• Magento Apache Config & Memory Issues

  - by cheshirepine

  I have a Magento installation on a VPS that is giving me a headache. This particular VPS has a reasonable spec - 2gb Memory and 50gb storage. It runs a single domain, with a single Magento install - and nothing else. About 5 months ago we started having issues. Every so often (about once every 2 or 3 weeks) the VPS would crash - all processes stopped and the only way to restart the container is via Virtuozzo. Now, however its 2 or 3 times a week. My VPS hosts confirm I am breaching the 2gb memory limit, at which point all VPS processes are killed to stop it bringing the entire node down. I have not made any config changes to it at all - I was running New Relic on it for a short while, but have removed that in case it was contributing to the issues. I can see nothing in the logs which indicates an issue and we have no CRON jobs running at the time the crashes happen. The site generates steady, but not huge amounts of traffic (averaging usually less than 100 visits per day) Is there anything in particular I should have done to the Apache or PHP configs to help? Im not a massivley experienced Apache admin, but know more than enough to solve most problems... Failing that, any other ideas that might help? Can't afford for this site to be down this much.

• Ruby on Rails (Redmine) on Apache - 503 Error

  - by andrewtweber

  I am running a Ruby on Rails application called Redmine. It's been working fine, but today it's giving a 503 Service Temporarily Unavailable error. (It was initially set up by an employee who is now gone.) I check the error log and it says: [Mon Nov 21 11:03:30 2011] [error] (111)Connection refused: proxy: HTTP: attempt to connect to 127.0.0.1:3000 (127.0.0.1) failed [Mon Nov 21 11:03:30 2011] [error] ap_proxy_connect_backend disabling worker for (127.0.0.1) Here's a chunk of my Apache config <VirtualHost *:80> ServerName redmine.{domain}.com RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f RewriteRule ^/(.*)$ balancer://redminecluster%{REQUEST_URI} [P,QSA,L] </VirtualHost> <Proxy balancer://redminecluster> BalancerMember http://127.0.0.1:3000 </Proxy> I found this link: http://www.redmine.org/boards/2/topics/20561 which suggests I simply need to "start the redmine server." I've tried /etc/init.d/redmine start which gives me this output => Booting Mongrel => Rails 2.3.11 application starting on http://0.0.0.0:3000 The contents of /etc/init.d/redmine: cd /var/redmine sudo ruby script/server -d -e production One thing I immediately notice is that it says 0.0.0.0 instead of 127.0.0.1. In addition, running top or ps -ef shows no record of a "mongrel" or "redmine" process. I've also tried restarting Apache before and after starting redmine. Not sure where to go from here.

• Apache subdomain not working

  - by tandu

  I'm running apache on my local machine and I'm trying to create a subdomain, but it's not working. Here is what I have (stripped down): <VirtualHost *:80> DocumentRoot /var/www/one ServerName one.localhost </VirtualHost> <VirtualHost *:80> DocumentRoot /var/www/two ServerName two.localhost </VirtualHost> I recently added one. The two entry has been around for a while, and it still works fine (displays the webpage when I go to two.localhost). In fact, I copied the entire two.localhost entry and simply changed two to one, but it's not working. I have tried each of the following: * `apachectl -k graceful` * `apachectl -k restart` * `/etc/init.d/apache2 restart` * `/etc/init.d/apache2 stop && !#:0 start` Apache will complain if /var/www/one does not exist, so I know it's doing something, but when I visit one.localhost in my browser, the browser complains that nothing is there. I put an index.html file there and also tried going to one.localhost/index.html directly, and the browser still won't fine it. This is very perplexing since the entry I copied from two.localhost is exactly the same .. not only that, but if something were wrong I would expect to get a 500 rather than the browser not being able to find anything. The error_log also has nothing extra.

• Dynamic virtual host configuration in Apache

  - by Kostas Andrianopoulos

  I want to make a virtual host in Apache with dynamic configuration for my websites. For example something like this would be perfect. <VirtualHost *:80> AssignUserId $domain webspaces ServerName $subdomain.$domain.$tld ServerAdmin admin@$domain.$tld DocumentRoot "/home/webspaces/$domain.$tld/subdomains/$subdomain" <Directory "/home/webspaces/$domain.$tld/subdomains/$subdomain"> .... </Directory> php_admin_value open_basedir "/tmp/:/usr/share/pear/:/home/webspaces/$domain.$tld/subdomains/$subdomain" </VirtualHost> $subdomain, $domain, $tld would be extracted from the HTTP_HOST variable using regex at request time. No more loads of configuration, no more apache reloading every x minutes, no more stupid logic. Notice that I use mpm-itk (AssignUserId directive) so each virtual host runs as a different user. I do not intend to change this part. Since now I have tried: - mod_vhost_alias but this allows dynamic configuration of only the document root. - mod_macro but this still requires the arguments of the vhost to be declared explicitly for each vhost. - I have read about mod_vhs and other modules which store configuration in a SQL or LDAP server which is not acceptable as there is no need for configuration! Those 3 necessary arguments can be generated at runtime. - I have seen some Perl suggestions like this, but as the author states $s->add_config would add a directive after every request, thus leading to a memory leak, and $r->add_config seems not to be a feasible solution.

• Apache 2 proxy for Tomcat 7

  - by hsnm

  Following the how-to, I wanted to make a proxy for traffic to the address /app to be processed by Tomcat 7. I added this to my httpd.conf: LoadModule proxy_module {path-to-modules}/mod_proxy.so LoadModule deflate_module modules/mod_deflate.so ProxyPass /app http://localhost:8081 ProxyPassReverse /app http://localhost:8081 I also have this on my server.xml: <Connector port="8081" enableLookups="false" acceptCount="100" connectionTimeout="20000" proxyName="localhost" proxyPort="80"/> And I have the folder /var/lib/tomcat7/webapps/app with my application files. I restarted both Tomcat 7 and Apache 2 after doing the configurations above. Problem: When navigating to my webpage.com/app, I get the error 500. I consulted apache logs, it says: [warn] proxy: No protocol handler was valid for the URL /app. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule. Update: This is running in ubuntu. I resolved this by adding LoadModule proxy_http_module modules/mod_proxy_http.so to my httpd.conf. Now I have another question: How can I make this proxy to work on SSL through port 443?

• Google Chrome audit on caching

  - by Álvaro G. Vicario

  If I run an audit on my sites with Google Chrome, I get this message in the Leverage browser caching section: The following resources are missing a cache expiration. Resources that do not specify an expiration may not be cached by browsers: A list of all the pictures follows. I get a similar notice in Leverage proxy caching: Consider adding a "Cache-Control: public" header to the following resources: Apart from pictures, I also get a notice about HTML, CSS and JavaScript files: The following resources are explicitly non-cacheable. Consider making them cacheable if possible: Its funny because I've worked hard to cache all static contents (except for pictures, where I just left Apache's default settings). Firefox does indeed store all these items in cache. Is there anything I should improve in my HTTP headers? Here's the complete header set of some items as loaded after removing the browser caché. Pictures use default settings I didn't really check before, the rest should be cachéd for three hours. I can set headers with both .htaccess and PHP.

• httpd.config Easy Apache WHM CentOS

  - by jessie

  First let me explain how I got to this situation. I run a Streaming Video Site. Videos are about 100-250MB in size at any given time there are 500 people on the site. So I guess that would make then static. Recently My site started getting really slow and the only way to fix it temporarily was to restart apache. Now there was no change in traffic that could have caused this. My site is not being attacked. My hosting company recomended to implement mpm_mod and suPHP. They did that by using Easy Apache in WHMS. Then everything was working fine but a little slow. I researched around and to my understanding that mpm will do that but be more table. I was told that installing FastCGI would speed things up just enough. Well that made everything worse. The site is slow and time's out. I used WHM and took off fastCGI but its still the same, it seems like everything i do as of now nothing changes. I even did a roll back on the htconfig file but that didn't work. I'm not sure how to fix this. and my hosting network guy wont be able to touch the problem until Tuesday. I have root access.

• Mac OS - Built SVN from source, now Apache2 not loading sites

  - by Geuis

  This relates to another question I asked earlier today. I built SVN 1.6.2 from source. In the process, it has completely screwed up my dev environment. After I built SVN, Apache wasn't loading. It was giving me this error: Syntax error on line 117 of /private/etc/apache2/httpd.conf: Cannot load /usr/libexec /apache2/mod_dav_svn.so into server: dlopen(/usr/libexec/apache2/mod_dav_svn.so, 10): no suitable image found. Did find:\n\t/usr/libexec/apache2/mod_dav_svn.so: mach-o, but wrong architecture It appears that SVN over-wrote the old mod_dav_svn.so and I am not able to get it to build as FAT, and I can't recover whatever was originally there. I resolved this(temporarily?) by commenting out the line that was loading the mod_dav_svn.so and got Apache to start at this point. However, even though Apache is running I am now getting this error when trying to access my dev sites: Directory index forbidden by Options directive: /usr/share/tomcat6/webapps/ROOT/ I have Apache2 sitting in front of Tomcat6. I access my local dev site using the internal name "http://localthesite". I have had virtual directories set up that have worked until this SVN debacle. Tomcat is installed at /usr/local/apache-tomcat, and webapps is /usr/local/apache-tomcat/webapps. Our production servers deploy tomcat to /usr/share/tomcat6, so I have symlinks setup on my system to replicate this as well. These point back to the actual installation path. This has all been working fine as well. None of our configurations for Apache2, Tomcat, or .htaccess have changed. Over the weekend, I performed a "Repair Disk Permissions" on the system. This was before I discovered the mod_dav_svn.so problem. I have been reading up on this all morning and the most common answer is that there is an Options -Indexes set. We have this in a config file, but it was there before and when I removed it during testing, I still got the same errors from Apache. At this point, I'm assuming I either totally borked the native Apache2 installation on this Mac, or that there is a permissions error somewhere that I'm missing. The permissions error could be from the SVN installation, or from my repair process. Does anyone have any idea what could be the problem? I'm totally blocked right now and have no idea where to check next.

• Incorrect gzipping of http requests, can't find who's doing it

  - by Ned Batchelder

  We're seeing some very strange mangling of HTTP responses, and we can't figure out what is doing it. We have an app server handling JSON requests. Occasionally, the response is returned gzipped, but with incorrect headers that prevent the browser from interpreting it correctly. The problem is intermittent, and changes behavior over time. Yesterday morning it seemed to fail 50% of the time, and in fact, seemed tied to one of our two load-balanced servers. Later in the afternoon, it was failing only 20 times out of 1000, and didn't correlate with an app server. The two app servers are running Apache 2.2 with mod_wsgi and a Django app stack. They have identical Apache configs and source trees, and even identical packages installed on Red Hat. There's a hardware load balancer in front, I don't know the make or model. Akamai is also part of the food chain, though we removed Akamai and still had the problem. Here's a good request and response: * Connected to example.com (97.7.79.129) port 80 (#0) > POST /claim/ HTTP/1.1 > User-Agent: curl/7.19.7 (x86_64-pc-linux-gnu) libcurl/7.19.7 OpenSSL/0.9.8k zlib/1.2.3.3 libidn/1.15 > Host: example.com > Accept: */* > Referer: http://example.com/apps/ > Accept-Encoding: gzip,deflate > Content-Length: 29 > Content-Type: application/x-www-form-urlencoded > } [data not shown] < HTTP/1.1 200 OK < Server: Apache/2 < Content-Language: en-us < Content-Encoding: identity < Content-Length: 47 < Content-Type: application/x-javascript < Connection: keep-alive < Vary: Accept-Encoding < { [data not shown] * Connection #0 to host example.com left intact * Closing connection #0 {"msg": "", "status": "OK", "printer_name": ""} And here's a bad one: * Connected to example.com (97.7.79.129) port 80 (#0) > POST /claim/ HTTP/1.1 > User-Agent: curl/7.19.7 (x86_64-pc-linux-gnu) libcurl/7.19.7 OpenSSL/0.9.8k zlib/1.2.3.3 libidn/1.15 > Host: example.com > Accept: */* > Referer: http://example.com/apps/ > Accept-Encoding: gzip,deflate > Content-Length: 29 > Content-Type: application/x-www-form-urlencoded > } [data not shown] < HTTP/1.1 200 OK < Server: Apache/2 < Content-Language: en-us < Content-Encoding: identity < Content-Type: application/x-javascript < Content-Encoding: gzip < Content-Length: 59 < Connection: keep-alive < Vary: Accept-Encoding < X-N: S < { [data not shown] * Connection #0 to host example.com left intact * Closing connection #0 ?V?-NW?RPR?QP*.I,)-???A??????????T??Z? ??/ There are two things to notice about the bad response: It has two Content-Encoding headers, and the browsers seem to use the first. So they see an identity encoding header, and gzipped content, so they can't interpret the response. The bad response has an extra "X-N: S" header. Perhaps if I could find out what intermediary adds "X-N: S" headers to responses, I could track down the culprit...

• Apache Reverse proxy for intranet and other integrated application on intranet

  - by user1433448

  I'm trying to configure a reverse proxy (ssl) with apache 2.2 in Debian Squeeze, but I have some problems, specially with some path absolute and with https I'll try to detail what I have made and what I'm trying to configure I have a server Debian Squeeze with apache2.2 + mod_proxy_html with: # apt-get install libapache2-mod-proxy-html libxml2-dev # a2enmod proxy # a2enmod proxy_http # a2enmod proxy_html # a2enmod headers After that I have configured a virtual host with: reverse_proxy_ssl.conf I'm trying to configure to allow access of our intranet from internet with a reverse proxy (apache that is located in DMZ). With this configuration domain.com/intranet works correctly and we can access to intranet, but we have one problem when from domain.com/intranet we need to use another internal application that is called from intranet with absolute path ( https://192.168.10.25/application/) and from internet appears that try to access with internal ip, and this link es incorrect from external site We only need to access from intranet to multiple internal application that are in external server and we like to restrict to minimal access from internet. All the application that are in the smae server of intranet are working. The second problem is with https and reverse proxy in our firewall appears some errors with packets (not valid packets), and with https seems to work. What can I do to solve this problems (absolute path and ssl problem) Thanks

• Apache directive for authenticated users?

  - by Alex Leach

  Using Apache 2.2, I would like to use mod_rewrite to redirect un-authenticated users to use https, if they are on http.. Is there a directive or condition one can test for whether a user is (not) authenticated? For example, I could have set up the restricted /foo location on my server:- <Location "/foo/"> Order deny,allow # Deny everyone, until authenticated... Deny from all # Authentication mechanism AuthType Basic AuthName "Members only" # AuthBasicProvider ... # ... Other authentication stuff here. # Users must be valid. Require valid-user # Logged-in users authorised to view child URLs: Satisfy any # If not SSL, respond with HTTP-redirect RewriteCond ${HTTPS} off RewriteRule /foo/?(.*)$ https://${SERVER_NAME}/foo/$2 [R=301,L] # SSL enforcement. SSLOptions FakeBasicAuth StrictRequire SSLRequireSSL SSLRequire %{SSL_CIPHER_USEKEYSIZE} >= 128 </Location> The problem here is that every file, in every subfolder, will be encrypted. This is quite unnecessary, but I see no reason to disallow it. What I would like is the RewriteRule to only be triggered during authentication. If a user is already authorised to view a folder, then I don't want the RewriteRule to be triggered. Is this possible? EDIT: I am not using any front-end HTML here. This is only using Apache's built-in directory browsing interface and its in-built authentication mechanisms. My <Directory> config is: <Directory ~ "/foo/"> Order allow,deny Allow from all AllowOverride None Options +Indexes +FollowSymLinks +Includes +MultiViews IndexOptions +FancyIndexing IndexOptions +XHTML IndexOptions NameWidth=* IndexOptions +TrackModified IndexOptions +SuppressHTMLPreamble IndexOptions +FoldersFirst IndexOptions +IgnoreCase IndexOptions Type=text/html </Directory>

• Problem posting multipart form data using Apache with mod_proxy to a mongrel instance

  - by Ryan E

  I am attempting to simulate my site's production environment as closely as I can on my local machine. This is a rails site that uses Apache w/ mod_proxy to forward requests to a mongrel cluster. On my Mac OSX Leopard machine, I have the default install of apache running and have configured a vhost to use mod_proxy to to forward requests to a local running mongrel instance on port 3000. <Proxy balancer://mongrel_cluster-development> BalancerMember http://127.0.0.1:3000 </Proxy> For the most part, this is working fine. I can browse my development site using the ServerName of the vhost I configured and can confirm that requests are being properly forwarded to the mongrel instance. However, there is a page on the site that has a multipart form that is used to upload an image to the server. When I post this form, there is a delay of about 5 minutes and the browser ultimately returns a Bad Request Your browser sent a request that this server could not understand. In the error log for my vhost: [Tue Sep 22 09:47:57 2009] [error] (70007)The timeout specified has expired: proxy: prefetch request body failed to 127.0.0.1:3000 (127.0.0.1) from ::1 () This same form works fine if I browse directly to the mongrel instance (http://127.0.0.1:3000). Anybody have any idea what the problem might be and how to fix it? If there is any important information that I neglected to include, post a comment, and I can add to this question. Note: Upon further investigation, this appears to be a problem specific to Safari. The form works fine in Firefox.

• Apache mod_proxy with SSL not redirecting

  - by simonszu

  I have a custom server running behind an apache reverse proxy. Since the custom server can only handle HTTP traffic, i am trying to use apache for wrapping proper SSL around it, and for some kind of HTTP authentication. So i enabled mod_proxy and mod_ssl and modified sites-available/default-ssl. The config is as following: <Location /server> order deny,allow allow from all AuthType Basic AuthName "Please log in" AuthUserFile /etc/apache2/htpasswd Require valid-user ProxyPass http://192.168.1.102:8181/server ProxyPassReverse http://192.168.1.102:8181/server </Location> The custom server is accessible from the internal network via the location specified in the ProxyPass directive. However, when the proxy is accessed from the outside, it presents the login prompt, and after successfully authenticated, i get a blank page with the words The resource can be found at http://192.168.1.102:8181/server. When i type the external URL again in an already authenticated browser instance, i am properly redirected to the server frontend. The access.log is full of entrys stating that my browser does successful GET requests, and the proxy is happily serving the /server ressource. However, the ressource isn't containing the server's frontend, but this blank page with these words on it.

• Concerns about Apache per-Vhost logging setup

  - by etienne

  I'm both senior developer and sysadmin in my company, so i'm trying to deal with the needs of both activities. I've set up our apache box, wich deals with 30-50 domains atm (and hopefully will grow larger) and hosts both production and development sites, with this directory structure: domains/ domains/domain.ext/ #FTPS chroot for user domain.ext domains/domain.ext/public #the DocumentRoot of http://domain.ext domains/domain.ext/logs domains/domain.ext/subdomains/sub.domain.ext domains/domain.ext/subdomains/sub.domain.ext/public #DocumentRoot of http://sub.domain.ext Each domain.ext Vhost runs with his dedicated user and group via mpm-itk, umask being 027, and the logs are stored via a piped sudo command, like this: ErrorLog "| /usr/bin/sudo -u nobody -g domain.ext tee -a domains/domain.ext/logs/sub.domain.ext_error.log" CustomLog "| /usr/bin/sudo -u nobody -g domain.ext tee -a domains/domain.ext/logs/sub.domain.ext_access.log" combined Now, i've read a lot about not letting the logs out of a very restricted directory, but the developers often need to give a quick look to a particular subdomain error log, and i don't really want to give them admin rights to look into /var/logs. Having them available into the ftp account is REALLY handy during development stages. Do you think this setup is viable and safe enough? To me it is apparently looking good, but i'm concerned about 3 security issues: -is the sudo pipe enough to deal with symlink exploits? Any catches i'm missing? -log dos: logs are in the same partition of all domains. got hundreds of gigs, but still, if one get disk-space dos'd, everything will break. Any workaround? Will a short timed logrotate suffice? -file descriptors limits: AFAIK the default limit for Apache on Ubuntu Server is currently 8192, which should be plenty enough to handle 2 log files per subdomain. Is it? Am i missing something? I hope to read some thoughts on the matter!

• eXist-db: can't start webstart client on a closed port, reverse proxied via apache

  - by rvdb

  I am configuring an Apache HTTP server so it reverse proxies requests starting with /app/ to an eXist-db instance running in a Tomcat server, on port 8082. This port has been closed in the firewall and is inaccessible to the outer world. Following the eXist documentation, I have following rules in place in my httpd.conf file: ProxyPass /apps/ http://localhost:8082/ ProxyPassReverse /apps/ http://localhost:8082/ ProxyPassReverseCookiePath /apps/ / All goes well for requests to e.g. 'http://mydomain/apps/exist/index.xml'. Yet, the webstart client (accessible at 'http://localhost:8082/exist/webstart/exist.jnlp' on the web server) doesn't work behind the proxy. While 'http://mydomain/apps/exist/webstart/exist.jnlp' does generate a valid exist.jnlp file, that file can't be executed. The reason seems quite obvious: apparently, the eXist-db instance generating the exist.jnlp file only sees the proxied request as: 'http://localhost:8082/exist/webstart/exist.jnlp'. Yet, since the exist.jnlp file is executed on the client, that reference is meaningless (unless the client computer happens to have an eXist-db instance running on that port). Executing the exist.jnlp file hence fails with a 'connection refused' error. Yet, there's no problem at all connecting a local eXist-db Java client to the proxied eXist instance with the URL xmldb:exist://mydomain/apps/exist/xmlrpc. The problem lies in generating the webstart exist.jnlp file, which seems to need access to a publicly accessible URL. However, opening port 8082 and replacing the Proxy references to 'http://localhost:8082' with 'http://mydomain:8082' IMO rather destroys the point of reverse proxying. Do others have had success reverse proxying eXist-db on a closed port behind Apache? Are there perhaps some Proxy configuration settings I have overlooked (I'm no expert at all) that can make eXist see the original request instead of the proxied one? Kind regards, Ron

• Installing mod_pagespeed (Apache module) on CentOS

  - by Sid B

  I have a CentOS (5.7 Final) system on which I already have Apache (2.2.3) installed. I have installed mod_pagespeed by following the instructions on: http://code.google.com/speed/page-speed/download.html and got the following while installing: # rpm -U mod-pagespeed-*.rpm warning: mod-pagespeed-beta_current_x86_64.rpm: Header V4 DSA signature: NOKEY, key ID 7fac5991 [ OK ] atd: [ OK ] It does appear to be installed properly: # apachectl -t -D DUMP_MODULES Loaded Modules: ... pagespeed_module (shared) And I've made the following changes in /etc/httpd/conf.d/pagespeed.conf Added: ModPagespeedEnableFilters collapse_whitespace,elide_attributes ModPagespeedEnableFilters combine_css,rewrite_css,move_css_to_head,inline_css ModPagespeedEnableFilters rewrite_javascript,inline_javascript ModPagespeedEnableFilters rewrite_images,insert_img_dimensions ModPagespeedEnableFilters extend_cache ModPagespeedEnableFilters remove_quotes,remove_comments ModPagespeedEnableFilters add_instrumentation Commented out the following lines in mod_pagespeed_statistics <Location /mod_pagespeed_statistics> **# Order allow,deny** # You may insert other "Allow from" lines to add hosts you want to # allow to look at generated statistics. Another possibility is # to comment out the "Order" and "Allow" options from the config # file, to allow any client that can reach your server to examine # statistics. This might be appropriate in an experimental setup or # if the Apache server is protected by a reverse proxy that will # filter URLs in some fashion. **# Allow from localhost** **# Allow from 127.0.0.1** SetHandler mod_pagespeed_statistics </Location> As a separate note, I'm trying to run the prescribed system tests as specified on google's site, but it gives the following error. I'm averse to updating wget on my server, as I'm sure there's no need for it for the actual module to function correctly. ./system_test.sh www.domain.com You have the wrong version of wget. 1.12 is required.

• Apache + PHP via FastCGI

  - by Wilco

  I'm running into some problems while attempting to run PHP via FastCGI in Apache. I have the FastCGI module loaded, but get the following error when attempting to load a page: The requested URL /fastcgi/php54.fcgi/index.php was not found on this server. Somewhere, it seems that the script to be executed is appended to the executable without any spaces. Is this where the problem likely is? Below I've included snippets from my Apache configuration (hopefully this is enough): LoadModule fastcgi_module libexec/apache2/mod_fastcgi.so FastCgiIpcDir /var/run/fastcgi AddHandler fastcgi-script .fcgi FastCgiConfig -autoUpdate -singleThreshold 100 -killInterval 300 AddType application/x-httpd-php .php ScriptAlias /fastcgi/ /Library/WebServer/FCGI-Executables/ <Directory "/Library/WebServer/FCGI-Executables"> Options +ExecCGI SetHandler fastcgi-script Order allow,deny Allow from all <VirtualHost *:80> ServerName www.somedomain.com ServerAdmin [email protected] DocumentRoot "/Web/www.somedomain.com" DirectoryIndex index.html index.php default.html CustomLog /var/log/apache2/access_log combinedvhost ErrorLog /var/log/apache2/error_log Action application/x-httpd-php /fastcgi/php54.fcgi <IfModule mod_ssl.c> SSLEngine Off SSLCipherSuite "ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM" SSLProtocol -ALL +SSLv3 +TLSv1 SSLProxyEngine On SSLProxyProtocol -ALL +SSLv3 +TLSv1 </IfModule> <Directory "/Web/www.somedomain.com"> Options All -Indexes +ExecCGI +Includes +MultiViews AllowOverride All <IfModule mod_dav.c> DAV Off </IfModule> <IfDefine !WEBSERVICE_ON> Deny from all ErrorDocument 403 /customerror/websitesoff403.html </IfDefine> </Directory> </VirtualHost> ... and this is the executable: #!/bin/sh PHP_FCGI_CHILDREN=1 PHP_FCGI_MAX_REQUESTS=5000 export PHP_FCGI_CHILDREN export PHP_FCGI_MAX_REQUESTS exec /opt/local/bin/php-cgi54

• Apache virtualhost - only apply script if file does not exist in document root

  - by Brett Thomas

  Sorry for the newbie apache question. I'm wondering if it's possible to set up the following non-conventional apache virtualhost (for a Django app): -- If a file exists in the DocumentRoot (/var/www) it will be shown. So if /var/www/foo.html exists, then it can be seen at www.example.com/foo.html. -- If file does not exist, it is served via a virtualhost. I'm using mod_wsgi with a WSGIScriptAlias directive that points to a Django app. So if there is no /var/www/bar.html, www.example.com/bar.html will be passed to the Django app, which may or may not be a 404 error. One option is to create an Alias for each individual file/directory, but people want to be able to post a file without adding an alias, and we want to keep the above URL structure for legacy reasons. Simplified Virtualhost is: <VirtualHost *:80> ServerName www.example.com DocumentRoot /var/www WSGIScriptAlias / /path/to/django.wsgi <Directory /path/to/app> Order allow,deny Allow from all </Directory> Alias /hi.html /var/www/hi.html </VirtualHost> The goal is to have www.example.com/hi.html work as above, without the Alias line

• Is there a /users/www-data type directory in RedHat/Fedora?

  - by Yarin

  I'm trying to setup web2py on my Fedora server, and the instructions, written for Debian, are telling me to install it in the /users/www-data directory. I realize that Fedora uses a default 'apache' user for running Apache, and Debian uses a 'www-data' user, but there's no corresponding /users/apache directory on my machine... Here are the instructions http://web2py.com/book/default/section/11/2

• Running WordPress and Ghost on Apache with mod_proxy

  - by Jack Perry

  I currently have three WordPress sites hosted on Apache with virtual host files to direct the right domain to the right DocumentRoot. Ghost (node.js) just came out and I've wanted to tinker with it and just play around on one of my spare domains. I'm not really interested in moving over to nginx so I'm trying to get Ghost working on Apache via mod_proxy. I've managed to get Ghost working on my spare domain, but I think there's a problem with my virtual host files, as all of my other domains start pointing to Ghost as well. Here are two virtual host files, one for my main WordPress site that works fine, and the second for Ghost. Domains removed and replaced with DOMAIN and DOMAIN2. DOMAIN <VirtualHost *:80> ServerAdmin webmaster@localhost ServerName DOMAIN.com ServerAlias www.DOMAIN.com DocumentRoot /var/www/DOMAIN.com/public_html <Directory /> Options FollowSymLinks AllowOverride All </Directory> <Directory /var/www/DOMAIN.com/public_html> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined Alias /doc/ "/usr/share/doc/" <Directory "/usr/share/doc/"> Options Indexes MultiViews FollowSymLinks AllowOverride None Order deny,allow Deny from all Allow from 127.0.0.0/255.0.0.0 ::1/128 </Directory> </VirtualHost> DOMAIN2 <VirtualHost IP:80> ServerAdmin EMAIL ServerName DOMAIN2.com ServerAlias www.DOMAIN2.com ProxyPreserveHost on ProxyPass / http://IP:2368/ </VirtualHost> I get the feeling I'm not working with virtual hosts or mod_proxy right, and Google-fu has let me down after many suggested attempts. Any ideas? Thanks!

• Local DNS and Apache Server Configuration Interferring - example.com / www.example.com

  - by nicorellius

  I have a domain for my site: example.com I am also running local DNS with these lines: www IN CNAME server.<host_provider>.com. dev IN CNAME server.<host_provider>.com. So www.example.com and dev.example.com go to production and development sites, respectively, that are hosted by a host company. In my Apache configuration for the main site, I'm running a rewrite rule like this: RewriteEngine ON RewriteCond %{HTTP_HOST} ^example\.com$|!dev\.example\.com$ [NC] RewriteRule ^(.*)$ http://www\.%{HTTP_HOST}/$1 [R=302,L,NE] This rule seems to work, as when you are off the network and go to example.com in the browser, you get redirected to www.example.com. The problem is when I'm on the network, and I go to example.com I get an error page, saying page can't be found. No server errors; just a page can't be found, as if the local DNS is causing it to stop looking at that point. I'm also using Nettica for DNS service and have this A record in place: example.com Host (A) Default xxx.xx.xxx.xx This handles the external DNS, but my problem seems to be related to my internal DNS. For example, inside my network, I can go to servers on the network with addresses like this: server.example.com server1.example.com server2.example.com These are configured in my local DNS. I'm just not sure how to get past the "empty" subdomain and go to example.com. Adding to this since it might not be clear. If I'm out side the example.com network, on another network, like example123.com, then when I go to example.com I'm redirected to www.example.com as expected, eg, the Apache rewrite rule is working. Thanks in advance for any information.

• Newbie queston: Cannot load http://localhost/phptest:8080/

  - by Princess Innah

  Hi guys, I decided to learn HTML so I installed apache on windows vista. Everything seems to work fine; when I go to http://localhost:8080 the sample webpage installed by apache shows. Apache is configured at port 8080. So far so good. Since my DocumentRoot is c:\pub, I made another folder inside, e.g., c:\pub\test. What I'm trying to figure out is why the page at http://localhost/test:8080 cannot load? It has index.html and apache is working fine. Any ideas?
