  • Googlebot repeatedly looks for files that aren't on my server

    - by John at CashCommons
    I'm hosting a site for a volunteer organization. I've moved the site to WordPress, but it wasn't always that way. I suspect at one point it was hacked badly. My Apache error log file has grown to 122 kB in just the past 18 hours. The large majority of the errors logged are of this form -- it's repeated hundreds of times today alone in my log files: [Mon Nov 12 18:29:27 2012] [error] [client xx.xxx.xx.xxx] File does not exist: /home/*******/public_html/*******.org/calendar.php [Mon Nov 12 18:29:27 2012] [error] [client xx.xxx.xx.xxx] File does not exist: /home/*******/public_html/*******.org/404.shtml (I verified that xx.xxx.xx.xxx was a Google server.) I suspect there was a security hole somewhere before, likely in calendar.php, that was exploited. The files don't exist anymore, but there may be many backlinks that exist that reference here, hence why googlebot is so interested in crawling them. How do I fix this gracefully? I still would like Google to index the site. I just want to tell it somehow not to look for these files anymore.

  • MySQL -- enable connection to remote server via local /tmp/mysql.sock

    - by Kevin
    Hey all, I run a shared hosting provider and we're looking to move to a High Availability (replicated across multiple datacenters) setup for our hosting. We have created a replicated MySQL setup with failover that works wonderfully, and we'd like to move all of our clients' databases to it. The only trouble is that we have many many customers, all of whom have configured their Wordpress, Drupal, etc. installations to connect to MySQL via a local socket, not to the address of the remove server. I would hate to have to go through manually and change the connection statement in all of our clients' sites. What I'd ideally love to see is a program that listens on /tmp/mysql.sock and forwards connections there to the remote server I specify. I've seen SQL Relay, but it seems to require that I hardcode all of the database names and usernames and passwords into its configuration file. This is not going to work for me because our users add new databases dynamically all of the time, and I'd rather not have to write code to updated SQLRelay's config file every time. Does anyone have an idea on how to do this? Alternatively, I'd accept idea on how to handle this at the PHP level. (i.e. redirect any attempted calls to mysql_connect() to use that hostname rather than localhost) Thanks, Kevin

  • howto configure proxy.conf for mod_proxy, apache2, jetty

    - by Kaustubh P
    Hello, This is how I have setup my environment, atm. An apache2 instance on port 80. Jetty instance on the same server, on port 8090. Use-Case: When I visit foo.com, I should see the webapp, which is hosted on jetty, port 8090. If I put foo.com/blog, I should see the wordpress blog, which is hosted on apache. (I read howtos on the web, and installed it using AMP.) Below are my various configuration files: /etc/apache2/mods-enabled/proxy.conf: ProxyPass / http://foo.com:8090/ << this is the jetty server ProxyPass /blog http://foo.com/blog ProxyRequests On ProxyVia On <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPreserveHost On ProxyStatus On /etc/apache2/httpd.conf: LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so LoadModule proxy_balancer_module /usr/lib/apache2/modules/mod_proxy_balancer.so LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so LoadModule proxy_ajp_module /usr/lib/apache2/modules/mod_proxy_ajp.so I have not created any other files, in sites-available or sites-enabled. Current situation: If I goto foo.com, I see the webapp. If I goto foo.com/blog, I see a HTTP ERROR 404 Problem accessing /errors/404.html. Reason: NOT_FOUND powered by jetty:// If I comment out the first ProxyPass line, then on foo.com, I only see the homepage, without CSS applied, ie, only text.. .. and going to foo.com/blog gives me a this error: The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /blog. Reason: Error reading from remote server I also cannot access /phpmyadmin, giving the same 404 NOT_FOUND error as above. I am running Debian squeeze on an Amazon EC2 Instance. Question: Where am I going wrong? What changes should I make in the proxy.conf (or another conf files) to be able to visit the blog?

  • How can I tell which page is creating a high-CPU-load httpd process?

    - by Greg
    I have a LAMP server (CentOS-based MediaTemple (DV) Extreme with 2GB RAM) running a customized Wordpress+bbPress combination . At about 30k pageviews per day the server is starting to groan. It stumbled earlier today for about 5 minutes when there was an influx of traffic. Even under normal conditions I can see that the virtual server is sometimes at 90%+ CPU load. Using Top I can often see 5-7 httpd processes that are each using 15-30% (and sometimes even 50%) CPU. Before we do a big optimization pass (our use of MySQL is probably the culprit) I would love to find the pages that are the main offenders and deal with them first. Is there a way that I can find out which specific requests were responsible for the most CPU-hungry httpd processes? I have found a lot of info on optimization in general, but nothing on this specific question. Secondly, I know there are a million variables, but if you have any insight on whether we should be at the boundaries of performance with a single dedicated virtual server with a site of this size, then I would love to hear your opinion. Should we be thinking about moving to a more powerful server, or should we be focused on optimization on the current server?

  • Why is this APC installation failing so badly?

    - by Matt
    I have multiple instances of APC running on my server with similar configurations (albeit with different cache sizes. However, one of the instances is performing extremely poorly, and I have no idea why (100% cache fragmentation, high miss rate). The runtime settings I'm using are as follows (pretty much out of the box): apc.cache_by_default 1 apc.canonicalize 1 apc.coredump_unmap 0 apc.enable_cli 0 apc.enabled 1 apc.file_md5 0 apc.file_update_protection 2 apc.filters apc.gc_ttl 3600 apc.include_once_override 0 apc.lazy_classes 0 apc.lazy_functions 0 apc.max_file_size 1M apc.mmap_file_mask apc.num_files_hint 1000 apc.preload_path apc.report_autofilter 0 apc.rfc1867 0 apc.rfc1867_freq 0 apc.rfc1867_name APC_UPLOAD_PROGRESS apc.rfc1867_prefix upload_ apc.rfc1867_ttl 3600 apc.shm_segments 1 apc.shm_size 10M apc.slam_defense 1 apc.stat 1 apc.stat_ctime 0 apc.ttl 0 apc.use_request_time 1 apc.user_entries_hint 4096 apc.user_ttl 0 apc.write_lock 1 APC is version 3.1.6, PHP is 5.3.3-1ubuntu9.5. I've tried restarting Apache multiple times, so this isn't a freak instance. The instance with problems is simply running Wordpress with a few plugins installed. All other instances (~4) on the server are running perfectly fine with almost 100% hit rates and 0% fragmentation; for example this instance is holding a website built using the Symfony framework. Any help would be much appreciated; I haven't had much experience with APC and was hoping for it to be an out-of-the-box speed boost ;).

  • apache 2.4 redirect within virtualhost

    - by user129545
    I have a couple http (port 80) vhosts that I want to redirect to http if an https request is made to them. Apparently some things have changed with Apache 2.4 (NameVirtualHost not used like it was in the past, etc). Apache 2.4 on centos 5.5, This is all using a single ip for all vhosts below, I don't have multiple ip's on this box, my /usr/local/apache2/conf/extra/httpd-vhosts.conf : # <VirtualHost www.dom1.com:80> ServerName www.dom1.com ServerAlias dom1.com DocumentRoot /usr/local/apache2/htdocs/dom1/wordpress </VirtualHost> <VirtualHost webmail.dom2.com:443> ServerName webmail.dom2.com DocumentRoot /usr/local/apache2/htdocs/webmail SSLEngine On SSLCertificateFile /usr/local/apache2/webmail.crt SSLCertificateKeyFile /usr/local/apache2/webmail.key </VirtualHost> # my /usr/local/apache2/conf/extra/httpd-ssl.conf, # Listen 443 SSLPassPhraseDialog builtin SSLSessionCache shmcb:/var/cache/mod_ssl/scache(512000) SSLSessionCacheTimeout 300 Mutex default SSLRandomSeed startup file:/dev/urandom 512 SSLRandomSeed connect builtin SSLCryptoDevice builtin # webmail.dom2.com works fine. Problem is I can connect to https://www.dom1.com, and it serves up the content from webmail.dom2.com. I want any https requests for www.dom1.com on port 443 to simply redirect to http://www.dom1.com on port 80. Thanks

  • Cannot 301 redirect with IIS URL Rewrite Module

    - by Justin
    I am trying to troubleshoot my issue with the URL Rewrite Module on IIS 7. I migrated a Wordpress blog over to BlogEngine.net. There were only about 5 entries that I wanted to use 301 redirects to the new blog, so I wanted to simply create 5 exact match redirect rules using the rewrite module. For some reason the exact match rule never seems to take effect, I always get a 404 error when the original url is navigated to. I verified that my exact match pattern matched the existing backlinks and it does. I then tried a simple test and got the same behavior, no redirection. I created a page, test.html, on my site, I then created a second page, test2.html. So my exact match pattern is: "http://www.mydomain.com/test.html" And the rule is supposed to do a 301 redirect to "http://www.mydomain.com/test2.html " The redirect never happens. I created the steps for the rule based on the instructions in this page: http://learn.iis.net/page.aspx/461/creating-rewrite-rules-for-the-url-rewrite-module/ I don't see that I left out a step. After I apply the rule I've even gone as far as doing an IISReset to make sure it would be in effect but still no luck. Any thoughts on what I might have left out? (Note: my rewrite rules dont include the " " around them but I had to add since serverfault thinks I am trying to spam the system with multiple urls.)

  • Switching from prefork MPM to worker MPM + php-fpm on ubuntu

    - by Shane
    All tutorials I found were how to fresh install worker MPM + PHP-FPM, since my wordpress blog's already up and running with prefork MPM, correct me if I'm wrong in the simulated installation process: I'm on ubuntu and according to some tutorials, the following lines would do all the tricks: apt-get install apache2-mpm-worker libapache2-mod-fastcgi php5-fpm php5-gd a2enmod actions fastcgi alias Then you setup configuration in /etc/apache2/conf.d/php5-fpm.conf: <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 -host 127.0.0.1:9000 -pass-header Authorization </IfModule> After all these, restart: service apache2 restart && service php5-fpm restart Question: 1) Would it cause any down time in the whole process for previously running sites with prefork MPM? 2) Do you have to change any already existent configuration files like php or mysql or apache2(would they take effect immediately after the switch without you doing anything)? 3) I've already have apc up and running, do you have to re-install/re-configure it after the switch? 4) How do you find out if apache2 is working in worker MPM mode as expected? Thanks a lot!

  • MySQL encoding problem after site move

    - by Quan Zhou
    Guys, I need your help. Since last month my friend has lost his database on Dreamhost, he decided to move his wordpress based blog site (written in Chinese) to my server. He's using a wp-plugin called wp-db-backup to perform regular db backups. And the servers backgrounds are: Dreamhost: Linux 2.6.31.5-modsign-aufs2-grsec-2-opt mysql Ver 14.12 Distrib 5.0.16, for pc-linux-gnu (i386) using readline 5.0 apache2 unknown version My Server: Linux li159-46 2.6.32.12-x86_64-linode12 mysql Ver 14.14 Distrib 5.1.45, for debian-linux-gnu (x86_64) using readline 6.1 nginx 0.8.36 His site's encoding was UTF-8 in both wp-config and db. I imported his db backup file in UTF-8 by default, then I sync'd files using rsync from dreamhost, then I just changed the db address and nothing more. But when I take first look at the "new" site, it was full of unreadable characters, I met this problem before, I changed charset options in browser but none of them can make it displayed properly. Then I converted his db to GB18030, it works with only if browser set charset to GB18030 either GBK, but by default they recognize the charset as UTF-8. I tried to edit the headers but it doesn't work. What could I do now? Thx~~

  • Trouble with IIS SMTP relaying to Gmail

    - by saille
    I appreciate that similar questions have been asked about how to setup SMTP relaying with IIS's virtual SMTP server. However I'm still completely stumped on this problem. Here's the setup: IIS 6.0 SMTP server running on Win2k3 box with a NAT'ed IP. Company uses Gmail for all email services. An app on the box needs to send email, so normally we'd just set the app up to talk to smtp.gmail.com directly, but this app doesn't support TLS. Easy, we just setup a local SMTP relay right? So I thought. What we have done so far: Setup IIS SMTP server to relay to smtp.gmail.com, as per these excellent instructions: http://fmuntean.wordpress.com/2008/10/26/how-to-configure-iis-smtp-server-to-forward-emails-using-a-gmail-account/ The local SMTP relay allows anonymous access. Both the local IP and the loopback IP have been explicitly allowed in the Connection and Relay dialogs. Tried sending email from 2 different apps via the local SMTP server, but failed (the emails end up in the Queue folder, but never get sent). The IIS logs show the conversation with the local app, but zero conversation happening with smtp.gmail.com. The port used by gmail is open outbound, and indeed the apps we have that support TLS can send email directly via smtp.gmail.com, so there is no problem with the network. At this point I changed the smtp settings in IIS SMTP server to use a different external SMTP server and hey-presto, the local apps can send email via local IIS SMTP relay. So smtp.gmail.com fails to work with our IIS SMTP relay, but another 3rd party SMTP service works fine. We need to use smtp.gmail.com, so how to troubleshoot this one?

  • Microsoft Arc Mouse OS X

    - by meepz
    I recently bought a new Mac Book Pro with Mountain Lion 10.8 on it. The only portable mouse I have is my Microsoft Arc Mouse. I wanted to use it with the laptop so I installed the IntelliPoint 8.2 for Mac from Microsofts website. According to their website, this driver is for OS X 10.4-10.7. Now I thought that wouldnt be too much of an issue but unfortunately for me, the driver installs fine and the mouse is detected but I get no movement and when I click the buttons nothing happens. I took the mouse with me on a business trip to EU and before I left I checked if the mouse worked with my desktop which is running Windows 7 and it worked without any hiccups. I'm not too sure where the OS differs from 10.7 to 10.8. I found an article online but it doesn't pertain to my mouse, although it could be of assistance. I have tried my version of their adjustment but I am not too knowledgable on low level hardware/software modifications so I may have done it wrong. heres the link: http://refluxions.wordpress.com/2008/08/18/mac-os-x-mouse-madnessfixed/ I get the following details when I check mouse info in the IntelliPoint preferences pane: The following Microsoft mouse devices are currently connected to your Macintosh driven by the Intellipoint software. Arc Mouse Vendor name: Microsoft Product name: Microsoft AE 2.4GHz Transceiver 5.0 Vendor ID: 045E Product ID: 074F Device version: 0140 if anyone has any suggestions on how to fix this it would be greatly appreciated! I love the mouse and im here in EU for another two weeks. Thanks

  • ntop to analyse bandwidth usage on multiple ASA 5505

    - by dunxd
    I have set up a netflow server at our data centre, which is connected via VPN to ~40 remote offices using Cisco ASA 5505. The aim is to analyse usage data and find out exactly how the remote connections are being used. I followed through http://techowto.files.wordpress.com/2008/09/ntop-guide.pdf to set up ntop and https://supportforums.cisco.com/docs/DOC-6114 to set up the ASAs. I can see from the Plugin Netflow Statistics page that netflow packets from my ASAs are being received - the counter is increasing. However, I am not seeing any breakdown on the Global Traffic Statistic page after switching to the Netflow interface. I'm just seeing a pie chart showing 100% traffic for eth0. The interfaces and documentation are a little hard to follow so I am not sure I have got things configured correctly. When setting up my NetFlow-device.2 I can specify Virtual NetFlow Interface Network Address - the web UI says This value is in the form of a network address and mask on the network where the actual NetFlow probe is located. is this a Network address (e.g. 192.168.0.0/24) or an actual host IP address (192.167.0.1/24)? If that should be a network address, is this the network in which one of my ASAs is or the network in which my ntop server is? If a host IP address, is this the IP address used by eth0 on my ntop server, the IP address of an ASA, or something else? Do I need a separate virtual interface for each ASA I am collecting netflow data from? Any guidance would be greatly welcome.

  • Access keystore on Sun ONE Webserver 6.1 for 2048 bit key length SSL

    - by George Bailey
    We want to get 2048 bit key length CSR requests. The browser based GUI provides us with a 1024 bit CSR and I don't know how to change that. It seems that 1024 bit key lengths will no longer supported by SSL companies. (Lower cost options only support 2048 bit. Thawte who is much more expensive say they accept 1024 for only one or two year certificates, but not 3). The legacy systems in question are running Sun ONE Webserver 6.1. Upgrading would be time consuming and we would rather not have to do that right now. We will be phasing these out but it will take awhile, so...

  • how many sites IIS 6 can handle

    - by Sarah Nasir
    Is there a limit for creating Sites in IIS. i have searched and some forums have it in discussion which says there is no limit. Someone mentioned that he has created upto 100,000 sites in IIS 6 but i dont know his server specs though. Personally i feel that whatever the limit of IIS, the resources will be run out well before the limit reaches. how do big sites like blogger and wordpress handle a huge number of sites on their server. Questions: 1) Is there an upper limit for IIS 6.0? if yes then what is it 2) What should be a good number of requests IIS should serve for a decent server? (I am not talking about dynamic requests on server or logs.) 3) Is there a way I can do the test run on my cloud to test the capability of my server. what factors should i keep in view. db request, page size, disk read/writes etc ? Response shall be highly appreciated.

  • Backup plan for linux webserver in small business?

    - by radman
    Hi, I am currently in the process of writing a backup plan for the webserver in use by my business. I am very new to this area and have a few ideas about how things should work but am unsure of what tools to use and what sort of restore process is appropriate. I'm looking for something relatively simplistic and it doesn't have to be 100% paranoid just enough to give me a reliable backup. Speed is not of the essence and there is not going to be a live fallback in place. The backup will be onto a single hdd that will be stored onsite (no option for offsite as yet). Backups will be taking place weekly. I am constrained by both time and money which is why I'm aiming for a good enough solution. Is taking an image of the webserver system drive periodically and using that as the backup appropriate? Should I be testing that the backups restore correctly every time that I perform one? This is a bit broad but what setup would you use if you were in my place, given the services I am running? Should I add additonal machines and split the services? Any advice is much appreciated!

  • I think installing PostFix solved my problem, but it seemed *too* easy

    - by Joel Marcey
    Hi, This is a followup to a serverfault post I made a while ago: http://serverfault.com/questions/21633/how-do-i-target-a-different-mail-server-depending-on-domain-with-exim (More context here too: http://forum.slicehost.com/comments.php?DiscussionID=3806 ) I have a slice/VPS at Slicehost. I basically decided to scrap exim (i.e., purge it), and start anew with my email infrastructure. In case you didn't read any of the above threads, basically my goal was to have a send only mail infrastructure that relays all outgoing email to Google Apps. I also wanted to where email from domain1 (a Wordpress installation) would show it coming from domain1.com and email from domain2 (a normal website) would show it coming from domain2.com. So I decided to give PostFix a try. I literally followed the surprisingly simple instructions here: http://sudhanshuraheja.com/2009/02/slicehost-setup-outgoing-mail-google-apps-postfix/ And voila, all seems to be working as I expected. My email tests show email coming from the proper locations (either domain1 or domain2 depending on where the emails were sent from). But this all seemed too simple to me. So simple, in fact, that I feel that something is amiss. When I installed PostFix according to the instructions in the post above and it worked, I was surprised that I didn't have to specify an SMTP server, a port number, any authentication credentials, etc. My slice is set up such that I have MX records for Google Apps (e.g., ASPMX.L.GOOGLE.COM.) in my DNS settings, but I am not sure if that is why it is working. My email infrastructure knowledge is admittedly limited, but with this am I suspect to: Spammers using my email infrastructure? My emails going to people as spam? Something else sinister? I have actually stopped running PostFix until I understand this better. Thanks!

  • Has anyone managed to build php5-xapian on Ubuntu 12.04?

    - by jetboy
    As Xapian's been dropped from the Ubuntu repositories, I'm attempting to build my own .deb from the instructions here: http://article.gmane.org/gmane.comp.search.xapian.general/8855 http://beeznest.wordpress.com/2011/07/06/howto-build-your-own-binaries-of-php-xapian-bindings-for-debian/ I can only get things to progress beyond the first few seconds by leaving out 'rm debian/control', but if I do, it looks as if the Python and Ruby bindings are building and passing their versions of smoketest correctly. However, the PHP part of the build is failing with this error: /home/charlie/xapian-bindings-1.2.8/php/smoketest.php:38: include(xapian.php): failed to open stream: No such file or directory FAIL: smoketest.php There's a xapian.php file in /home/charlie/xapian-bindings-1.2.8/php/php5/ but if I copy it to /home/charlie/xapian-bindings-1.2.8/php/ or change the path to it in smoketest.php, the build fails right near the start with: dpkg-source: error: aborting due to unexpected upstream changes Unfortunately I'm out of my comfort zone building from source. Anyone got any ideas? Edit post James' answer: Builds fine if I follow instructions exactly. I built it on a test VM initially, but that didn't build the PHP package as PHP itself wasn't installed. Obvious gotcha, but worth mentioning. Installing generated the following error: Setting up php5-xapian (1.2.8-1) ... Processing triggers for libapache2-mod-php5 ... dpkg (subprocess): unable to execute installed post-installation script (/var/lib/dpkg/info/libapache2-mod-php5.postinst): Permission denied ssion denied dpkg: error processing libapache2-mod-php5 (--install): subprocess installed post-installation script returned error exit status 2 Errors were encountered while processing: libapache2-mod-php5 It's only a script for restarting Apache. Stopping Apache before running sudo dpkg -i php5-xapian_*.deb prevents the error. Xapian now shows up in phpinfo(). Job done. Thanks.

  • Website has become slower on a VPS, was much fast on a shared host. What's wrong?

    - by Arpit Tambi
    My shared host suspended my website stating system overload, so I moved my website to a VPS which has 4GB RAM. But for some reason the website has become very slow. This is the vmstat output - procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu------ r b swpd free buff cache si so bi bo in cs us sy id wa st 1 0 0 3050500 0 0 0 0 0 1 0 0 0 0 100 0 0 Here's the Apache Benchmark output for a STATIC html page I ran on the server itself - Benchmarking www.ask-oracle.com (be patient)...apr_poll: The timeout specified has expired (70007) Total of 20 requests completed Update: Server Config: List item Centos 5.6 4 cores cpu 4 GB RAM LAMP stack with APC Wordpress Only one website It takes almost double time to load now, same website was much fast on shared hosting. I know I need to tweak some settings but have no clue where to start from? I have already tried to optimize apache, mysql etc. Update 2: CPU usage is low, see uptime output: 11:09:02 up 7 days, 21:26, 1 user, load average: 0.09, 0.11, 0.09 Update 3: When I load any webpage, browser shows "Waiting" for a long time and then page loads quickly. So I suspect server can accept only limited connections and holds extra connections in a waiting state. How to check this?

  • PHP script not automatically updating when moved to another server

    - by user32007
    A friend built a ranking system on his site and I am trying to host in on mine via WordPress and Go Daddy. It updates for him but when I load it to my site, it works for 6 hours, but as soon as the reload is supposed to occur, it errors and I get a 500 timeout error. His page is at: jeremynoeljohnson .com/yakezieclub My page is currently at http://sweatingthebigstuff.com/yakezieclub but when you ?reload=1 it will give the error. Any idea why this might be happening? Any settings that I might need to change? Here is the top of the index.php file. I'm not sure which part of any of it is messing up. I literally uploaded the same code as him. Here's the reload part: $cachefile = "rankings.html"; $daycachefile = "rankings_history.xml"; $cachetime = (60 * 60) * 6; // every 6 hours, the cache refreshes $daycachetime = (60 * 60) * 24; // every 24 hours, the history will be written to // - or whenever the page is requested after 24 hours has passed $writenewdata = false; if (!empty($_GET['reload'])) { if ($_GET['reload']== 1) { $cachetime = 1; } } if (!empty($_GET['reloadhistory'])) { if ($_GET['reloadhistory'] == 1) { $daycachetime = 1; $cachetime = 1; } } if (file_exists($daycachefile) && (time() - $daycachetime < filemtime($daycachefile))) { // Do nothing } else { $writenewdata = true; $cachetime = 1; } // Serve from the cache if it is younger than $cachetime if (file_exists($cachefile) && (time() - $cachetime < filemtime($cachefile))) { include($cachefile); echo "<!-- Cached ".date('jS F Y H:i', filemtime($cachefile))." -->"; exit; } ob_start(); // start the output buffer ?>

  • Permissions nightmare - tried all I know

    - by Ben
    Working on a new client's dev site, which is a wordpress install on a Plesk box. I have SSH root access, and FTP access through a separate account. What I've done so far Initially I couldn't make any changes to any files at all. The permissions on all the template files looked a little screwy (644), so I figured change them to allow group, and add myself to the group: CHMOD Recursive on the theme folder to set everything to 664 Quickly realised I'd broken it, set the folders to 755, kept files as 664 Ownership on all files is a mixture of root:root and 500:500 (there is no user nor group with the ID of 500 on the server). Added myself to the group 'root' so I could modify the files too The Problem This worked OK, in terms of being able to edit the existing files, so I began working. However, I can't upload to the directory, even having run CHOWN -R root:root templatefolder/ and being in the root group. I feel like I must be missing something obvious, and it's doing my head in. Questions: Files in the install owned by 500 with group 500 - I've looked in /etc/group and /etc/passwd and there is no user nor group with this ID. Is that left over from another developer's setup or the previous server (they moved recently)? Is being in the 'root' group enough, or do I need to own the theme folder as 'myftpuser' in order to upload and create new files? Like I say, I have edit access, so I got myself this far. I'm now questioning what to do next!
