• Enable fastcgi on SSL Virtualhost

  - by ggstevens

  Debian 7.5 My VirtualHost for port 80 works fine with the ifmodule for fastcgi. However, it does not work with the VirtualHost for port 443. SSL/https:// was working fine until I added the following: <IfModule mod_fastcgi.c> AddHandler php5-fcgi .php Action php5-fcgi /php5-fcgi Alias /php5-fcgi /usr/lib/cgi-bin/php5-fcgi FastCgiExternalServer /usr/lib/cgi-bin/php5-fcgi -socket /var/run/php5-fpm.sock -pass-header Authorization </IfModule> When I try to restart Apache I get an error: Reloading web server config: apache2 failed! However, if I remove the FastCgiExternalServer line, it works.

• haproxy not passing X_FORWARD_FOR on HTTP POST

  - by Mark L

  Hello, I've setup HAProxy with the option forwardfor option so it'll pass on the user's IP to PHP via $_SERVER[ "HTTP_X_FORWARDED_FOR" ]. If the page request isn't a POST it's populated fine but if it is then it won't be populated. Any ideas where I've gone wrong? Thanks everyone!

• Social-Networking Startup, Hosting Plan

  - by pws5068

  I've created a social networking community which is soon ready to release, and I'm trying to decide on a type of hosting plan. I have considered options such as VPS and Reseller plans. I anticipate (or hope for at least) a significant amount of traffic/bandwidth in the not-too-distant future. If I open a reseller, will I receive the same amount of server lag during busy hours that I do with a shared account? How significant is the profit margin with the reseller option? Aside from generalized "configurability", what advantages merit purchasing a VPS? Is there anything stopping me from reselling space on a VPS account? Features I need Include: PHP, MySql, Unlimited Domains, Ruby on Rails, Remote Database Connections

• sql and web encoding problem

  - by Marki

  Guys, I've got an encoding problem I believe. I have upgraded from phpBB2 to phpBB3. The old databases were in latin1, the new ones have utf8 encoding. Already during the upgrade process some rows of the DB were only read partly into the new version, because of strange characters as it turned out. When I use PHP's mb_convert_encoding() function to convert those strings to UTF8 they end up e.g. as 0x0093, i.e. they must have been some kind of double quotes. Even after doing this conversion, they still show up as 0x0093 in the browser (the squares with 0093 in them when the browser does not know what to display). Can someone explain the problem here? I'm a little confused and afraid I don't see all the dependencies that need to work to have the correct encodings and the correct display thereof...

• What to do for a 1 million concurrent web application? [duplicate]

  - by Amit Singh

  This question already has an answer here: How do you do load testing and capacity planning for web sites? 3 answers There are few things that I would like to know here. What server configuration do I need. And if I am deploying it on EC2 how many VMs do I need and what should be their configuration. What options do I have to do a load testing for 1 million concurrent users. Any pointer to (for php) how to code or what to keep in mind for such application. This is for sure that I don't exactly know what to ask because this is my first application on this scale. But one thing is clear that this application should pass a load test of 1 million concurrent request.

• What kind of server do I need to handle 10 million requests and mySQL queries a day?

  - by Calvin

  I'm a new bie of server administration and I'm looking for a powerful hosting service to host my new website. This website is basically a back-end of an mobile online game, and it will: handle up to 10 million of HTTPS request and mySQL queries a day store up to 2000 GB file on the hard disk transfer probably 5000 GB data in and out per month it runs on PHP and mySQL have 10 million records in mySQL database, for each record there are 5-10 fields, around 100 bytes each I really don't know what kind of a server I need to handle these requirements, my question is: what cpu/ram do I need for a dedicated server or vps? what hosting companies are able to offer this kind of dedicated server or VPS? what about cloud computing? I've researched Amazon EC2 but it seems complicated to me. And I've contacted Rackspace but strangely they said Cloudsites is not suitable for my requirements. I wonder if there is other cloud hosting company. any other alternative method? thanks very much!

• variables in batch files

  - by richzilla

  Hi All, Im trying to set up a batch file to automatically deploy a php app to a web server, and basically what i want is an entirely automated process where i would just give it a revision number from the repository and it would then export the files, upload via ftp and then update deployment info at the repo host (codebase). However, im starting from scratch here, and im wanting to know, how would i set up a batch file to accept a variable when it was run, for example typing myfile.bat /revision 42 would enable me to deploy revision 42 to my server. if anyone can point me in the right direction id be very appreciated.

• Would a Socket Connection Outperform an Intarvaled Database Sweep and Requests?

  - by Jascha

  I'm building a small chat application to add to an existing framework. There will only be 20-50 users MAX at any one time. I was wondering if I could get away with updating a cache file containing (semi) live chat data for whichever users happen to be chatting just by performing timed queries and regular AJAX refreshes for new data as opposed to learning how to open and maintain a socket connection. I'm sure there are existing chat plug-ins out there. But I just had a hell of a time installing one and I could see building the whole damn thing taking just as much time as plugging one in. Am I off to a bad start? Thanks in advance -J (p.s. this is a semi closed network behind a php login so security isn't a great concern)

• W3 Total Cache or WP Super Cache?

  - by javipas

  I'm just preparing the setup of a new VPS where I will migrate a WordPress blog with a good traffic (currently, around 40k pageviews a day), and I was thinking about the caching strategy. I've found different ideas and recommendations, but from previous experiences I will setup a Nginx+PHP-FPM+MySQL (LEMP) system on a Linode VPS. I've read also about setting Nginx as a reverse proxy with Apache, and even using Varnish too, but I don't know if all of this can benefit the speed/performance of the blog (that's the only thing that will be installed on the VPS). The question now is... would you recommend W3 Total Cache or WP Super Cache? I've used W3 on some blogs, but I haven't noticed great benefits and don't need all its options, so I think I could give the veteran WP Super Cache a try. Besides, some users have complained about W3 complex configuration and lack of performance (even consumig more CPU) on some cases.

• Can a web server and XBMC HTPC co exist happily?

  - by Mild Fuzz

  I have a machine that is currently dedicated to running my home theatre. It is way more powerful than it needs to be, and spec wise would have no problem running both a few websites and an HTPC What I wanted to know is that is this was a reasonable thing to expect of a single machine? 90% of the time, all it's power would be just for the web server ( and the odd torrent) Currently it's running Windows, but I am pretty sure I will have to turn it into a Linux box Will I run into any problems? Is there anything I need to know before I start? Any prerequisites? The webserver will be required to run Ruby on Rails sites mainly, but might be called upon to run PHP for Wordpress also.

• Can't make updates with LDAP from Linux box to Windows AD

  - by amburnside

  I have a webapp (built using Zend Framework - PHP) that runs on a Linux environment which needs to authenticate against Active Directory on a Windows server. So far my webapp can authenticate with LDAPS, but cannot perform any kind of write operation (add/update/delete). It can only read. I have configured my server as follows: I have exported the CA Certificate from my Windows AD server to /etc/opendldap/certs I have created a pem file based on this certificate using openssl I have update /etc/openldap/ldap.conf so that it knows where to look for the pem certificate: TLS_CACERT /etc/openldap/certs/xyz.internal.pem When I run my script, I get the following error: 0x35 (Server is unwilling to perform; 0000209A: SvcErr: DSID-031A1021, problem 5003 (WILL_NOT_PERFORM), data 0 ): Have I missed something with my configuration, which is causing the server to reject making updates to AD?

• Blocking a specific URL by IP (a URL create by mod-rewrite)

  - by Alex

  We need to block a specific URL for anyone not on a local IP (anyone without a 192.168.. address) We however cannot use apache's <Directory /var/www/foo/bar> Order allow,deny Allow from 192.168 </Directory> <Files /var/www/foo/bar> Order allow,deny Allow from 192.168 <Files> Because these would block specific files or directories, we need to block a specific URL which is created by mod-rewrite and the page is dynamically created using PHP. Any ideas would be greatly appreciated

• What ports do I need open for IMAP connections

  - by iamjonesy

  I'm developing a web application that connects to an IMAP mailbox and fetches emails as part of it's functionality. The application is PHP and I'm connecting like this: public function connect() { /* connect to gmail */ $hostname = '{imap.gmail.com:993/imap/ssl}INBOX'; $username = $this->username; $password = $this->password; /* try to connect */ $this->inbox = imap_open($hostname,$username,$password) or die('Cannot connect to Gmail: ' . imap_last_error()); } Developing locally on my mac this was fine, I was able to connect and get emails. However now that I've put the app on my web hosts server I'm getting the following error: Cannot connect to Gmail: Can't connect to gmail-imap.l.google.com,993: Connection timed out After checking with my hosting provider they told me outgoing connections on port 993 are blocked. Is there anyway around this? Otherwise I need to upgrade to a dedicated server :S

• Having many subdomains with SSL--best practices?

  - by jnunn

  I have a site that has many subdomains (one for each client). The content for each subdomain will be different, pulling different data, different layouts etc, so I don't think I can just alias one directory to many different sub domains. My question is, what's the best practice for doing this? Each subdomain will need SSL. My setup is Amazon EC2 (ubuntu) Wildcard SSL for my domain (*.mydomain.com) Apache 2 PHP (LAMP) Currently, I'm just creating a new entry into "/etc/hosts" and an appropriate spot in the web root (ie /var/www/abc.mydomain.com, /var/www/def.mydomain.com, etc). I've just discovered that I'll need a unique IP for each subdomain, and that's tricky with EC2 as they limit you to the number you can have (unless you jump through some hoops). Right now I have about 10 subdomains, which is manageable, but theoretically I could have thousands. Am I doing it the only way possible or is there a better way I should investigate?

• Webserver security, intrusion detection, and file intregrity

  - by enfield

  I would like to add some type of tracking / alerting on some linux webservers running PHP and Apache. In doing searches I have come across a lot of info from 2006-2009. Would like to revisit things and see what others are doing now. The main purpose here is to track when any files are changed and if so alert me somehow. The same goes for IDS and hopefully something that can reside on same server? Since some of these are small scale projects I would prefer opensource/free solutions that are really effective. Although I would still like to hear of other alternatives if someone has the experience and the cost can be justified.

• Dedicated Server emails ending up in Junk

  - by Pasta

  I have a dedicated server that works fine. Recently I added a new domain with a new dedicated IP address. The emails from the webserver gets sent out from the primary IP address which is different from the IP address of the domain. This causes the emails to end up in the Junk email folders. Is there anything I can do changing the SMTP server to the new IP address or configuring send mail? I need this for my php server on centos.

• Can Apache 2 be configured to start sending gzipped data early?

  - by rikh

  We have Apache set up to gzip compress html pages before they are sent to the client browser. However, some of our pages are slowish to generate and it seems that Apache is holding on until it has the complete page, compressing it, then sending it to the browser. There are big chunks of the page (the main important bits) that are actually generated and output fairly quickly. Is it possible to configure Apache to start compressing and send data for the page as soon as the script starts outputting something? Is it is, can you offer any help is how to do this? If not, can you suggest any other way to get gzip compression working for the server? The scripts that generate the pages are written in PHP. We are using Apache 2.0 on Linux.

• Can't escape single quotes in shell

  - by user13743

  I'm trying to make a command to do a perl substitution on a batch of php files in a directory. The string I want to replace has single quotes in it, and I can't get it to properly escape the in shell. I tried echoing the string with unescaped quotes, to see what perl would be getting: echo 's/require_once('include.constants.php');/require_once('include.constants.php');require_once("./functions/include.session.inc.php");/g' and it doesn't have the single-quotes in the result: s/require_once\(include.constants.php\);/require_once\(include.constants.php\);require_once\("\./functions/include\.session\.inc\.php"\);/g However, when I try to escape the single quotes: echo 's/require_once\(\'include\.constants\.php\'\);/require_once\(\'include\.constants\.php\'\);require_once\("\./functions/include\.session\.inc\.php"\);/g' I get the prompt to complete the command: > What I want it to parse to is this: What am I doing wrong? s/require_once\('include.constants.php'\);/require_once\('include.constants.php'\);require_once\("\./functions/include\.session\.inc\.php"\);/g

• Wordpress multisite and redirect

  - by Dr I

  I come to you because I'm facing a really strange effect on my hosting. I currently manage a server contening a NGINX/PHP-CGI and a wordpress multisite in it. My sites are created using subsite.domaine.tld, for now, my three subsites are correctly accessibles through the url: subsite.domain.tld. My goal is to allow my subsite on the host domain to be access through their respective unique domain. For exemple: www.domainA.com would redirect to subsite1.host.domain.tld. If I do that using the following setting on the domainA Public DNS: www 10800 IN CNAME subsite1.host.domain.tld. When I try to access www.domainA.com I don't go to subsite1.host.domain.tld but instead I'm redirect to the Wordpress ROOT site where I create my Network (host.domain.tld). Is there a trick to deal with?

• Sendmail relay out of Amazon EC2?

  - by Stephen Belanger

  I have a site running on CentOS 5.4 through Amazon EC2. Unfortunately, Amazon has had nothing but trouble with their entire IP range getting black listed from spam tracking services regularly. I need a mail server, so I setup an smtp server elsewhere that I want to send to, but I can't just send directly to it through PHP because the direct smtp request is way too slow. What I want to do is relay through sendmail, but I've never used sendmail before, so I have no idea how to configure it. All I want is for all emails sent from localhost to be relayed to one specific external server, but I don't know how to do that. I tried to find a tutorial online, but couldn't find anything that was particularly clear as to how I go about doing that. Can anyone help me out?

• Automatic server redirect that passes through as the referring site

  - by nsearle

  Hey All, As always, I would like to thank all of your help and assistance in advance. I am looking for a way to automatically redirect a user to a site and maintain the redirect site as the referral site. Let me explain the process and what is needed in a step by step format. User clicks on a desired link in an email User is navigated to testdomain.com User is automatically redirected to test.com/landing test.com sees testdomain.com as the referral site Data is gathered via Google Analytics I am unsure as if this PHP code will take care of it, or not - header("Location: http://google.com", true, 303); I could test and that is most likely what I am going to do. But I would like to understand a little more as to WHY this would or WHY this wouldn't work.

• Outgoing mail from linux not being delivered

  - by Jason

  I can't seem to send mail through my php scripts or through the linux console on my Centos 5.5 LAMP server, when the email is addressed to go to a domain that is hosted by my box. I think it is something to do with the email routing internally, or the DNS servers that the box uses not reporting the correct MX records. Basically my box doesn't host any mail, it's all hosted on google apps. My name servers are hosted by a 3rd party provider and I am using webmin. Webmin doesn't recognise the settings on the 3rd party provider. I'm unsure how to fix this. Previously when I had this problem on a cpanel server, I would edit the remotedomains and localdomains files, moving domains from one file to another and it would fix the problem. What information do I need to provide for anyone to work out what the issue is? Thanks
