SuPHP Or EAccelerator

Jul 22, 2009

I have a Linux server for shared hosting in which I am using Cpanel/WHM. I have PHP running as suPHP which I believe is for security. The problem I am facing is a lot of PHP based websites create load on the server and consume as much as 10% of the CPU and sometimes some script even consumes 50% CPU. I think I can reduce the load caused by the PHP scripts by installing eAccelerator. However, it does not work with PHP running as suPHP. Can anybody tell me which one should I choose of the both? Is there any other way to reduce the load on the server?

Eaccelerator Eaccelerator.shm_ttl

Apr 30, 2008

Does anyone have a recommendation for the eaccelerator eaccelerator.shm_ttl setting? If it was left at the default of "0", this means no newer scripts would ever be cached once the memory is full. Or would it do additional caching on disk as well and not show up in the phpino.php file?

We have alloted 32 Megs of Ram for eA. Maybe something like this would help move some old scripts out of the cache?

eaccelerator.shm_ttl="86400"
eaccelerator.shm_prune_period="0"

Eaccelerator

Apr 14, 2008

When eAccelerator doesn't have enough free shared memory to cache a new script it will remove all scripts from shared memory cache that haven't been accessed in at least shm_ttl seconds. By default this value is set to "0" which means that eAccelerator won't try to remove any old scripts from shared memory.

Does that mean that once the shared memory is full, that even if a script that is in shared memory hasn't been accessed in 5 months, any new scripts will have to be ran off of the compiled versions on disk instead of being read out of the much-faster RAM?

EAccelerator

i installed eAccelerator, everything look good, exept i have a problem with Wifidog-auth server that i have installed, it gives me errors that it cant connect to database.... but not all the times, could eaccelarator be doing this? it was fine before i installed EA

Suphp

Nov 13, 2007

I use "suphp" on 3 servers I own with apache 2.2.6 and suddenly yesterday (15 hours ago) one of the servers show "Internal server error" on all sites.

Tried rebuilding apache and php 4 times with no fix until I came to try handling php with cgi instead. (I always like to track who is using apache processes)

well. getting to this fix was after 10 hours of all sites not working on the server.

now (5 minutes ago) I go to http://www.suphp.org to read their docs for solution to find this

Quote:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, hostmaster@marsching.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.
Apache Server at www.suphp.org Port 80

Why did this suddenly arise while No changes were done on server software or config?

I believe this happens after the first coming apache restart or something but dunno what was the reason yet

maybe suphp.org guys have to update us when their site comes back online

Installing EAccelerator

Jun 22, 2009

I successfully installed eAccelerator and its already working fine then I decided to update my PHP version which is 5.1.6 to 5.2.6 after the upgrade eAccelerator is no longer loaded I tried recompiling eAccelerator but to no avail it doesnt load anymore I double checked eaccelerator.ini and it was already set. Someone said that the phpize that was installed in my server is not compatible to PHP5.2.6 and it needs to be updated also but I cant seem to update it since it always says that it is already updated.

I am using CentOS5.3.

Install EAccelerator

Jun 6, 2008

I've got a CentOS 5.0 machine running PHP 4 & 5 in FastCGI mode with suPHP.

I've read the instructions to install eAccelerator at: InstallFromSource - eAccelerator - Trac

However there is a line at the beginning that says it is safe to follow those directions if you have ONE php install.

I have php5 as default and php4 optional. Does this count as 1 or 2 installs?

EAccelerator Error

Apr 5, 2007

Everything was working fine until I upgraded from PHP 5.2.0 to PHP 5.2.1. I compiled from source to upgrade, and I installed PHP 5.2.0 from source. Once I upgraded, eAccelerator complained that I had to recompile it again for it to work on 5.2.1. I did and it gave me the same error. I recompiled maybe 10 times and it has still complained about it. How do I fix this error?

EAccelerator And Zend Optimizer

Feb 23, 2007

I am using PHP 5.2.1 (recently upgraded), Apache 2.2.4.

Before the upgrade, I had Zend Optimer and eAccelerator installed.

However, after upgrade of Apache and PHP + I had to reboot the server, I went on to reinstall eAccelerator.

Here is what php -v gave me :

=================
eAccelerator requires Zend Engine API version 220051024.
The zend Engine API version 220060519 which is installed, is newer.

contact eAccelerator at http://eaccelerator.net for a later version of eAccelerator.

SuPHP On A Dedicated Server

Oct 18, 2009

I'm running a dedicated server (ie my site only) which is primarily a vbulletin powered site.

I was wondering if it is beneficial in running PHP as suPHP along with suhosin?

A lot of articles I see seem to be aimed at shared setups where there are other users with various (possibly) untrusted scripts.

It is a WHM/cPanel managed server which by default is set to run PHP5 as DSO (Apache module).

suexec is installed however this only affect CGI scripts correct?

I recently had a (paid) security audit completed and I asked the question about suhosin. The reply I got was:

Quote:

You do not need suhosin as you do not run suPHP we enforce posix acl's which will prevent vulnerable scripts from being able to download to the system easily and prevent the automated attacks. You can try this by installing a phpshell and you will see it's not very effective, only php functions are really of any use (such as readfile() and so on) but it will prevent things like wget xxx.

Should I recompile Apache (via EasyApache) with suPHP and suhosin or just leave as is?

Suphp Working With Vsftpd

Apr 23, 2009

I am setting up a shared Server with apache2 and php5 + suhosin +suPHP + vsftpd.

The Directory Structure is:

1. DocumentRoot

/var/www/virtual/website1
/var/www/virtual/website2
/var/www/virtual/website3
............etc

2. For each website I would create a system account and tie it to each virutal host(as required by suPHP)

chown -R John:group1 /var/www/virtual/website1
chown -R Mary:group1 /var/www/virtual/website2
chown -R Ben:group1 /var/www/virtual/website3
...........etc

<VirtualHost 192.168.100.44>
DocumentRoot /var/www/virtual/website1
ServerName www.website1.com
suPHP_UserGroup John group1
</VirtualHost>

<VirtualHost 192.168.100.45>
DocumentRoot /var/www/virtual/website2
ServerName www.website2.com
suPHP_UserGroup Mary group1
</VirtualHost>
........etc

3. I setup vsftpd with chroot to each virtual host.

This works very nice as long as each client has only one ftp account. But if a client(website1) wants to have multiple ftp accounts( ex. john, john100, john200), they would mess up the file ownership when they upload and change files. Since suPHP executes PHP scripts with the permissions of their owners (suPHP_UserGroup John group1, suPHP would complain their setid is mismatched because the John100 is not the suPHP_USERGROUP owner(John). I have tried Virtual Hosting with Vsftpd and Mysql, that didn't work because all the virutal users would be acting as one user (guest_username=virtualftp) when they upload and change files. I am wondering if there is ways to allow multiple ftp accounts for each Virutal host working together with suPHP. Or It is possible for ftp user to change ownership once they log in.

SuPHP + CGI PHP And Zombie Processes

May 28, 2009

OS: CentOS 5
Software: Apache 2 / PHP CGI 5.8 / suPHP

Today I took the leap and switched to suPHP, rather than the Apache module. This is just what suited us best for hosting our own websites, keeping them more isolated from eachother bar a certain shared directory.

All is great, apart from I'm now noticing Zombie processes all of the time. These processes do seem to go away though, if I watch top the amount of Zombie processes will go up and down between 0 and 10.

Code:
17471 gnation 15 0 0 0 0 Z 1 0.0 0:00.03 php-cgi <defunct>
17463 gnation 16 0 0 0 0 Z 1 0.0 0:00.02 php-cgi <defunct>
17467 gnation 16 0 0 0 0 Z 1 0.0 0:00.02 php-cgi <defunct>

Are these processes a problem, considering they do leave after a while? I've read up about Zombie processes and it would seem that as long as they are closing at some point, instead of hanging around, then that's fine. Is this supposed to happen in my setup?
