I've already asked this on Stack Overflow but received no response, so I'm trying my luck here.

I'm new to configuring Apache and I'm trying to optimize my Apache server. Reading through the documentation, I found that I should be using the Event MPM instead of the Prefork MPM. Everything was straight forward until this point as I only had to comment out Prefork and uncomment Event in 00-mpm.conf. However, when I restarted Apache, I got the following error -

AH00526: Syntax error on line 31 of /etc/httpd/conf.d/php.conf: Invalid command 'php_value', perhaps misspelled or defined by a module not included in the server configuration

Digging for some more information, I found out that mod_php should not be used with Event. So, I'm commented out php_value in php.conf and also commented out LoadModule in 10-php.conf.

My webpages wouldn't load anymore and I realized that I should be using php-fpm. However, documentation regarding this is really unclear and I'm not sure how to use it. I tried this -

[root@ip-xxx-xx-xx-xxx ~]# yum install php-fpm
Loaded plugins: amazon-id, rhui-lb, search-disabled-repos

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

I'm not sure how to proceed and would really appreciate any help with this problem. Thank you!

When using PHP-FPM you have no PHP configuration in Apache other than the directives used to map the request for PHP files to the back end FPM service (ProxyPass or a RewriteRule with the [P] flag)

php_value is a directive implemented by mod_php and so can only be used in setups that use mod_php itself.

Check the PHP-FPM documentation for details on how to replicate this functionality.

Other than that you seem to have a PHP package version inconsistency that needs to be resolved first. It looks like and upgrade from php-fpm before v5.5 is not supported, so you'll need to either use the one you have currently installed or resolve the problem manually.
