apache2.4でのpreforkのチューニング

apache2.2ではhttpd.confに設定する部分があったが、 2.4では場所が変わっていたためメモ。

sudo vi /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

#以下を追記
<IfModule mpm_prefork_module>
    StartServers 10
    MinSpareServers 10
    MaxSpareServers 10
    ServerLimit 10
    MaxClients 10
    MaxRequestsPerChild 50
</IfModule>
