This article mainly describes how to configure PHP-FPM, common error resolution and PHP-FPM startup, shutdown, and restart.

The Nginx in the LNMP environment does not support PHP and requires the FASTCGI plug-in to process requests for PHP. and PHP needs to php-fpm This component to provide this functionality. Prior to php5.3.3 version php-fpm is in the form of a patch package, and php5.3.3 can only use –ENABLE-FPM to load the module at the time of compiling the installation, without installing it separately.

[root@localhost php-5.6.25]#/usr/local/php/sbin/php-fpm

[29-aug-2016 17:36:05] error:failed toopen configuration file '/usr/local/php/etc/php-fpm.conf ': No such file Ordirectory (2)

[29-aug-2016 17:36:05] error:failed toload configuration file '/usr/local/php/etc/php-fpm.conf '

[29-aug-2016 17:36:05] Error:fpminitialization failed

Startup PHP-FPM found a lack of configuration files/usr/local/php/etc/php-fpm.conf

At this point, just copy the PHP-FPM profile in the installation of PHP configuration files provided by the template/usr/local/php/etc/php-fpm.conf.default to the appropriate directory, there are two ways, you can provide a configuration file, that is, the last class copy to/ usr/local/php/etc/or/usr/local/etc/rename to php-fpm.conf

[root@localhost etc]# cd/usr/local/php/etc/

[root@localhost etc]# ls

Pear.conf Php-fpm.conf.default

[root@localhost etc]# cp/usr/local/php/etc/php-fpm.conf/usr/local/etc/php-fpm.conf

Use/USR/LOCAL/PHP/SBIN/PHP-FPM to start FPM

[root@localhost etc]#/usr/local/php/sbin/php-fpm

Ii

[root@localhost etc] #cp php-fpm.conf.defaultphp-fpm.conf

[root@localhost etc]#/usr/local/php/sbin/php-fpm

 

This PHP-FPM configuration is complete, since the FPM is placed between PHP and Nginx application, so configure the service to boot.

The following configuration php-fpm starts in service form

[root@localhost etc]# cd/usr/local/php-5.6.25/

[root@localhost php-5.6.25]# cp./sapi/fpm/init.d.php-fpm/etc/init.d/php-fpm

[root@localhost php-5.6.25]# ll/etc/init.d/php-fpm

-rw-r--r--1 root root 2354 August 3115:54/etc/init.d/php-fpm

[root@localhost php-5.6.25]# chmod a+x/etc/init.d/php-fpm

[root@localhost php-5.6.25]# ll/etc/init.d/php-fpm

-rwxr-xr-x 1 root root 2354 August 3115:54/etc/init.d/php-fpm

[Root@localhost php-5.6.25]#/etc/init.d/php-fpmstart

Gracefully shutting down PHP-FPM warning,no pid file found-php-fpm are not running?

When the PHP-FPM service is turned off, an error is found, the lack of PID files, the solution is to edit the configuration file, enable the PID file

[root@localhost etc]# vim php-fpm.conf

pid = Run/php-fpm.pid

[Root@localhost etc]# kill-int ' cat/usr/local/php/var/run/php-fpm.pid '

Cat:/usr/local/php/var/run/php-fpm.pid: No file or directory

[Root@localhost etc]#/etc/init.d/php-fpm Stop

Gracefully shutting down PHP-FPM warning,no pid file found-php-fpm are not running?

If you try to shut down the service again, create the Php-fpm.pid file manually

[root@localhost etc]# cd/usr/local/php/var/run/

[root@localhost run]# vim Php-fpm.pid

[Root@localhost run]# ls

Php-fpm.pid

[root@localhost run]# service php-fpm Stop

[root@localhost run]# service php-fpm start

[Root@localhost run]# NETSTAT-TUNLP |grep 9000

[root@localhost run]# netstat-tunlp |grep 9000

STARTINGPHP-FPM Done

Add service to Chkconfig list, set boot up

[root@localhost run]# chkconfig--add php-fpm

[root@localhost run]# chkconfig php-fpm on

 

now that the PHP-FPM configuration is complete, there are two ways to control

①PHP-FPM uses signal control:

INT, TERM immediately terminated

QUIT Smooth Termination

USR1 Reopen the log file

USR2 Smooth overload of all worker processes and reload configuration and binary modules

Start

[Root@localhost run]#/USR/LOCAL/PHP/SBIN/PHP-FPM

Shut down:

[Root@localhost run]# kill-int ' cat/usr/local/php/var/run/php-fpm.pid '

Reboot:

[Root@localhost run]# kill-usr2 ' cat/usr/local/php/var/run/php-fpm.pid '

Service Mode Control

Usage:/etc/init.d/php-fpm{start|stop|force-quit|restart|reload|status}

[root@localhost run]# service php-fpm start

Starting php-fpm Done

[root@localhost run]# service php-fpm Stop

[root@localhost run]#/etc/init.d/php-fpm Restart
