Apache PHP-CGI SuExec Session Issues

After enabling php-cgi and suexec to handle your site in Apache, you may discover issues with your web applications working incorrectly. This could simply be a session issue which is result of the suexec user being unable to write into /var/lib/php/session directory.

You can verify this problem simply by looking websites error log.

First, lets identify the SuExec user configured for your site. Simply open your Apache configuration file and identify value set for “SuexecUserGroup”.

As you can see the value “user1″ has been set as the SuExec user. Now we need allow user1 access to the /var/lib/php/session directory. The simplest way to do this is to add user1 into the apache group. This is done by editing your /etc/group file and appending the line for the Apache group with your user.

Look for the apache group and append your user, save and close the file (:wq)

….and you’re done, you don’t even have to restart Apache.
