Apache FCGID MPM_Worker on 512MB + 16CPU VPS

[LeGastronome]

Hello,

I run one eshopping website + WordPress Blog on a VPS.

I just notice that on this server (16CPU), MPM_Worker is faster than Prefork.

But for RAM usage, I have a lot of /usr/bin/php running each 5MB of ram everytimes !

Memory Used 64.8 %
Server Load 0.23 (16 cpus)

My current config is :

Apache :

TraceEnable Off
ServerSignature Off
ServerTokens ProductOnly
FileETag None
StartServers 2
<IfModule prefork.c>
MinSpareServers 3 
MaxSpareServers 8
</IfModule>
MaxClients 15
MaxRequestsPerChild 500
ThreadsPerChild 3

FCGID :

<IfModule mod_fcgid.so>
        # Maximum number of PHP processes
        MaxProcessCount             4
        # Number of seconds of idle time before a php-cgi process is terminated
        IPCCommTimeout              200
        IdleTimeout                 60
	 IdleScanInterval		 60
</IfModule>

mod_fcgid status:

Total FastCGI processes: 7
Process name: php5

Pid	Active	Idle	Accesses	State
32639	443	6	30	Ready
18131	694	122	95	Ready
32472	444	135	21	Ready
Process name: php5

Pid	Active	Idle	Accesses	State
15955	203	123	10	Ready
23663	610	122	20	Ready
15969	201	201	1	Ready
15960	203	188	4	Ready

How could I reduce PHP idle ? and PHP footprint ?

Thanks !

Maybe you are affected by bug 48981
See https://svn.apache.org/repos/asf/htt.../CHANGES-FCGID
make sure you run mod_fcgid 2.3.6

How could I know the module version ?

For EasyApache, I just need to change the mod_fcgi.so ?

Thanks

1) you may access a non-existing URL om your server and read module version from error page footer
2) you may configure /server-status (mod_status), access it and read module versions
3) you may check in /home/cpeasyapache/src
Yes compiling and replacing mod_fgcid.so should work

Thanks :

I have this : mod_fcgid/2.3.5

Could I install it just in changing .so ?

download 2.3.6, read installation instructions, install
remove superfluous LoadModule modules/mod_fcgid.so from httpd.conf as you already have it in /etc/httpd/conf/php.conf
restart apache
