What are the basic prerequisites to enable PHP opcache

Hello guys. I'm trying to enable a server to use PHP opcache as I did in other EA4 installs, but is not installing it.

I discovered after repeated compilations and trial and error, that to enable opcache, EA4 requires to precompile the system including:

• Apache MPM: mpm_worker
• Apache modules: mod_suphp + mod_suexec + mod_cgid + mod_proxy_fcgi
• PHP modules: php_build + php_devel + php_runtime + php-fpm + php-opcache + php-zendguard (?)

In some servers this combination made the trick, but there is one of them not obbeying and opcache is not being included in phpinfo reports
Can you confirm if this is ok or may I be missing something important?

Best regards

 

Hello @cPanelMichael, thanks for answering. I'm already aware of all these recomendations. I was trying to enable OPCache under PHP 5.6.25, with Apache 2.4 using mpm_worker and the modules I listed above, which are theoretically compatible with it. In fact, I cloned one of the default templates that are currently shipped with cPanel, which already include OPCache, but it just don't integrate the OPCache PHP module when provisioning, it just ignores the request to do that.

I also tried to find the DSO Apache module but it's not present in the list of options.

So, should I open a ticket? or may this be a EA4 bug?

 

@Erel:
Do you know if there is anyway to use mpm_worker + OPCache + fcgid?

 

ok @cPanelMichael, it's frustrating but I started following the feature request and monitor page changes in the Current Status of EasyApache 4 - EasyApache 4 - cPanel Documentation and also in EA4 changelog to see when it is available. (for those also interested: you can monitor changes in webpages with this free webservice).


Well now I have 3 more questions:
1) As per the performance solution, what would you recommend to reach the best possible speed without fcgi in crowded servers (+200 accounts)? Maybe mod_cgi + PHP opcache + apache mpm_worker?

2) If fcgi is not supported, why are these modules present in the EA4 options:

• ea-apache24-mod_cgid
• ea-apache24-mod_proxy_fcgi
• ea-php55-php-fpm
• ea-php56-php-fpm
• ea-php70-php-fpm

3) What's the difference between ea-apache24-mod_cgid and ea-apache24-mod_cgi?

Thanks

 

Ok, thanks for the clarifications.

So, usage of *-php-fpm modules is officially discouraged? Still, using opcache seems to be the closest approach to a PHP optimization by now. Is this correct?

So, mod_cgid is completely unrelated to fcgid. Similar names but not similar functionality. Is this correct?
