Sentora and php-fpm

[hrace009]

no as the security model will be broken. Notice in apache 2.4 performance have improved a lot.

Yeah, but if i have a website with a lot of requests, apache handler is not the good choice, not in my case. Sentora is the only control panel that i see that use the apache handler, other use usually the fastcgi or fpm technology.

Starting from version 2.4 apache offers 3 MPM we can choose, it’s depend in what you needs.

• prefork MPM uses multiple child processes without threading. Each process handles one connection at a time without creating separate threads for each.
  
• worker MPM uses several threads per child processes, where each thread handles one connection at a time.
  
• event MPM It is similar to the worker MPM in that it also creates multiple threads per child process but with an advantage: it causes KeepAlive or idle connections (while they remain in that state) to be handled by a single thread, thus freeing up memory that can be allocated to other threads. This MPM is not suitable for non-thread-safe modules like mod_php, to use event MPM, PHP-FPM must be used instead.
  

check the MPM used by your Apache:

Code:

[root@panel ~]# httpd -V

To change this, edit /etc/httpd/conf.modules.d/00-mpm.conf
and uncomment the line that loads mpm_event_module

Code:

LoadModule mpm_event_module modules/mod_mpm_event.so

install php-fpm, fcgi,mod_fcgid

Code:

# yum -y install php-fpm mod_fcgid fcgi

change /etc/php-fpm.d/www.conf

Code:

listen = /var/run/php-fpm/socket.sock

change php handler in order to use php-fpm in /etc/httpd/conf.d/php.conf

Code:

<FilesMatch \.php$>
#    SetHandler application/x-httpd-php
     SetHandler "proxy:unix:/var/run/php-fpm/socket.sock|fcgi://localhost"
</FilesMatch>

Restart Service

Code:

# systemctl start php-fpm.service
# systemctl enable php-fpm.service
# systemctl restart httpd.service

go to your phpinfo();
