Cause
php package in OS repositories includes incorrect syntax in /etc/httpd/conf.d/php.conf: php_value parameters are included without <IfModule mod_php5.c> tags:
# tail -5 /etc/httpd/conf.d/php.conf
# Apache specific PHP configuration options
# those can be override in each configured vhost
#
php_value session.save_handler "files"
php_value session.save_path "/var/lib/php/session"
Resolution
- Connect to the server via SSH
- Create a backup of the configuration file:
# cp /etc/httpd/conf.d/php.conf{,.orig}
- Edit
/etc/httpd/conf.d/php.conffile in any text editor and edit the syntax to include the<IfModule mod_php5.c>tags:
BEFORE:php_value session.save_handler "files"
php_value session.save_path "/var/lib/php/session"AFTER:
<IfModule mod_php5.c>
php_value session.save_handler "files"
php_value session.save_path "/var/lib/php/session"
</IfModule>
