SuPHP Or EAccelerator

Eaccelerator Eaccelerator.shm_ttl
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
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
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
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
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
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
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.

PHP 5.2.1 (cli) (built: Feb 23 2007 11:36:11)

the version of eAccelerator I tried to install is the latest one ( 0.95)

SuPHP On A Dedicated Server
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
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.

Eaccelerator Cache Emptying Cron
I'm sure all of you who use eaccelerator know how big the cache can get and that it needs emptied manually. Well at least to my knowledge it does, the only thing I have seen that you can configure is the shm pruning. If anyone does know such a feature with eaccelerator please share. But I also notice a performance decrease and a few php errors mostly related to memory allocations here and there.

Anyway I was piddling around and came up with a command to disable eaccelerator from php.ini, delete the cache folder and then enable it back. I figured this would be good as a daily cron. I would like some input if anyone knows any better ways.

So I wanted to share this in case someone else here has the same problems with eaccelerator cache folder getting huge. If anyone knows a way to make this better or shorter please reply with solution.

Of course this will vary depending on where your php.ini is and where your eaccelerator cache is. Just replace those values with yours. I'm sure there is also a way to use similar commands to find and input these values, again if anyone knows please share.

Code:
find /usr/local/lib -name 'php.ini' | xargs perl -pi -e 's/extension="eaccelerator.so"/;extension="eaccelerator.so"/g' ; rm -rf /usr/lib/php/eacc ; mkdir /usr/lib/php/eacc ; chmod 4777 /usr/lib/php/eacc ; find /usr/local/lib -name 'php.ini' | xargs perl -pi -e 's/;extension="eaccelerator.so"/extension="eaccelerator.so"/g'

Alternative To SuPHP (phpsuexec) For Plesk
As all we know suPHP or phpsuexec are coded to let apache run the script with file's owners name and not the "nobody"

1- Plesk does not support phpsuexec but its possible to setup suPHP on plesk! Any comment, suggestion experience?

2-My alternative
I create a group for each single user named "apacheUSERNAME" and will assign both apache and the user to this group.

Then I will change the group for any file/directory that needs 777 permission.But instead 775.
Again suggestions are appreciated

3-Final comparator should be server load; How will be the server performance(load) with or without suPHP or phpsuexec

How Does A SuPHP Upgrade Mess Up A Website
One of my client's website is now hosed.

When I go to all of the html pages, I get a message box that says You have chosen to open [blank line] which is a: text/x-server-parsed-html. The blank line means there is nothing there no filename.

An email from the webhost said that a suPHP upgrade(?) caused this.

The only PHP file I have is one that reads text files to put up on a News page.

I am confused as to exactly how a suPHP upgrade which I have never heard of until today can cause this much damage.

# To customize this VirtualHost use an include file at the following location
# Include "/usr/local/apache/conf/userdata/std/2/xxx/xxx.com/*.conf"

</VirtualHost>

Scripts are running with user's UID, and that is fine, but it can still read /etc/passwd file for example.

How to fix that? Is it really open_basedir value is ignored by susphp? It works fine if I remove suphp and run scripts with nobody uid.

Smooth Migration From Mod_php To Suphp
When cpanel has apache 2.2 available. I am planning on switching my servers over to it and to SuPHP from mod_php. There are hundreds of accounts on my different servers and I am worried about the transition. I know cpanel has a permission conversion script, but I dont completely trust it. The biggest issue to me though, is all the users that have php_values and flags in their htaccess files that would then be needed converted to php.ini's. Has anyone created a conversion script for doing this in an automated fashion?

I might not even convert my full servers to this and just do with the partial ones (less than 25%), but I really think it would benefit the customers and myself with the nice added layer of protection of suphp.

DirectAdmin./SUPHP (Anyone Run This Combo)
A server I have runs DA. On this server I switched php to SUPHP. This combo has worked 99% good so far except for one big pain in the ***.

When ever a new domain, sub domain or a pointer domain is added I get a php_admin_flag error and Apache will not restart untill I rem out all instances of php_admin_flag lines in the httpd.conf file.

Code:
Stopping httpd: [FAILED] Starting httpd: Syntax error on line 31 of /usr/local/directadmin/data/users/****/httpd.conf: Invalid command 'php_admin_flag', perhaps mis-spelled or defined by a module not included in the server configuration [FAILED]

Has anyone solved this? Apperantely the new version of DA was suppose to fix this but I upgraded DA today and at the end I ended having to rem out all php_admin_flag instances for all domains on that server which = good times.

Few days ago I realize I hadn't updated this server for a while. I run 'apt-get update' and 'apt-get dist-upgrade' . A whole lot of things get updated, and after that I perform a reboot, as adviced by the update script.

The next day I experiment a bit with the profiler of xdebug . I manage to install it , play around with the results, but decide to uncomment it from php.ini again as it is not that helpfull to me and it makes quiet big log files too.

Today I notice this server is getting very big loads. Normally on peak evenings it would float around 2-4 , with sometime jumps to 10-12 but always quickly recovering and working well. But on this evening it kept rising, stayed around 30-60 for most of the time, and even hit up to 85 . It only lowers when the busy hours are really over. So I look around everywhere , and then after a few hours I notice that eaccelerator is not visible in phpinfo(); anymore. This is the only weird thing I could find, and I assume this caused a big difference on the performance.

I dont know why exactly it went away. Maybe it was the server update, wich touched a lot of files. But I thought it was not supposed to update any configuration files, not without warning at least. I could also have been the xdebug script, wich also uses 'phpize' to install and also required editing in php.ini . I really wish I noticed the lack of eaccelerator after the update but before trying xdebug.

So I try to install eaccelerator again. Unpack from source, phpize, make, etc etc, just as last time. I edit php.ini to make sure the load command and settings of eaccelerator are still there and reload apache. I check phpinfo(); , but nothing changes. I try it all again to be sure, but still nothing. I check the location of the .so files, yes they are still there and the rights of the files look ok.

I edit php.ini again and uncomment 'extension=mysql.so', and reload apache. I notice a mysql error on my site as expected. So that means I'm really editing the right php.ini file and that I can influence the extensions that are loaded. I add the mysql extension again and reload apache.

I load an old php.ini backup file, from right after first installation of this server. The eaccelerator settings are there too already, but if I try it and reload apache : no difference.

I reboot my server again, because .. well sometimes it helps. But not with this. phpinfo(); still says no eaccelerator.

I check another server, exact same specs, same php+eaccelerator installation on the same day as the first one. I compare versions of apache/php/php extensions/zend extensions and all numbers I can find. Everything still looks the same, except server 1 does not have eaccelerator and server 2 still has.

I'm shomehow out of things to check now. I'm pretty sure eaccelerator has a big influence on the performance of my heavy php site, and I want it back. Everything looks ok, the files are there, the settings in php.ini are there, it should work ... but it doesnt. No errors or warnings anywhere, just phpinfo(); saying that eaccelerator has not been loaded and the high loads are confirming this.

It will either be a very complicated solution, or a very simple one, but I'm just looking over it. Does anyone has any tips on where to look or what to try ? Thanks.

Enable Zlib Compression If EAccelerator Is Already Installed
Does it make sense to enable zlib compression if eAccelerator is already installed? I'm running PHP 5.2.1 (FastCGI) with lighttpd 1.4.13 and eAccelerator 0.9.5. Also, here's a more general question. Since I manually compiled these programs, how would I go about updating them with the source files? Would I just repeat the normal installation process with the new source files?

Opcode Caches And Segfaults (XCache, EAccelerator)
Running gallery2 on a box with 4GB RAM. Tried PHP 5.2 w/XCache then with eAccelerator, both caused segmentation faults after a couple days.

"In a previous article, I stressed a common problem with all PHP op-code caches/accelerators: they die with segmentation faults every once in a while."
[url]

Anybody using logwatcher? How many faults per day do you get? If you're using a cache and never get segfaults how busy is your site and how do you prevent them?

SuPHP + CGI PHP And Zombie Processes
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?
