Default fcgid configuration is wrong...

[kilburn]

Warning: This is the configuration I like to use in my servers, but there are no guarantees that they are going to work well in your case (you *have* to adjust the min/max processes to prevent too many php5-cgi processes eating all your server's ram). Additionally, this is only tested in Debian squeeze.

First of all, we have to edit the wrapper being called by mod_fcgid. At this aim, start by modifying the *users* wrapper template found in "/etc/ispcp/fcgi/parts/php5-fcgi-starter.tpl":

Code:

#!/bin/sh

umask 022

PHPRC="{PHP_STARTER_DIR}/{DMN_NAME}/php5/"
export PHPRC

TMPDIR="{WWW_DIR}/{DMN_NAME}/phptmp"
export TMPDIR

PHP_FCGI_CHILDREN=0
export PHP_FCGI_CHILDREN

PHP_FCGI_MAX_REQUEST=1000
export PHP_FCGI_MAX_REQUEST

exec {PHP5_FASTCGI_BIN}

Next, we also need to modify the *panel's* wrapper template, that is located in "/etc/ispcp/fcgi/parts/master/php5-fcgi-starter.tpl":

Code:

#!/bin/sh

umask 022

PHPRC="{PHP_STARTER_DIR}/{DMN_NAME}/php5/"
export PHPRC

PHP_FCGI_CHILDREN=0
export PHP_FCGI_CHILDREN

PHP_FCGI_MAX_REQUEST=1000
export PHP_FCGI_MAX_REQUEST

TMPDIR="{GUI_ROOT_DIR}/phptmp"
export TMPDIR

exec {PHP5_FASTCGI_BIN}

Now that the wrappers are properly configured, lets see the mod_fcgid specific settings. These are setup in the "/etc/apache2/mods-enabled/fcgid_ispcp.conf":

Finally, you just need to regenerate the configuration files so that your changes to the templates are made effective.
