Mudando de MPM Worker para Event com PHP-FPM

Question

CentOS 7, Apache 2.4, FPM / FastCGI, MariaDB

Meu VPS de 512M está consumindo memória com um site de desenvolvimento WordPress, então espero que isso me leve a um caminho de melhor sintonia; se não, por favor informe.

Estou tentando mudar de MPM Worker para MPM Event, mas estou recebendo o seguinte erro após a reinicialização do Apache:

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

/etc/httpd/conf.modules.d/00-mpm.conf

# Select the MPM module which should be used by uncommenting exactly
# one of the following LoadModule lines:

# prefork MPM: Implements a non-threaded, pre-forking web server
# See: http://httpd.apache.org/docs/2.4/mod/prefork.html
#LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

# worker MPM: Multi-Processing Module implementing a hybrid
# multi-threaded multi-process web server
# See: http://httpd.apache.org/docs/2.4/mod/worker.html
#
#LoadModule mpm_worker_module modules/mod_mpm_worker.so

# event MPM: A variant of the worker MPM with the goal of consuming
# threads only for connections with active processing
# See: http://httpd.apache.org/docs/2.4/mod/event.html
#
LoadModule mpm_event_module modules/mod_mpm_event.so

php_value session.save_handler "files"
php_value session.save_path    "/var/lib/php/session"

    

Answer 1

Descobri que eu precisava fazer as linhas finais do meu php.conf condicional.

<IfModule mpm_prefork_module>
#
# 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"
</IfModule>
