This article mainly shows you "what are the startup methods in php-fpm", the content is simple and clear, and I hope it can help you solve your doubts. Let me lead you to study and learn this article "what are the startup methods in php-fpm".

Various startup methods of php-fpm:

The easiest operation to start php-fpm is:

/ usr/local/php/sbin/php-fpm

Php-fpm after php 5.3.3 no longer supports commands such as / usr/local/php/sbin/php-fpm (start | stop | reload) that php-fpm used to have, so don't look at such old commands, you need to use signal control:

The master process can understand the following signals:

INT, TERM is terminated immediately.

QUIT smooth termination

USR1 reopens the log file

USR2 smoothly reloads all worker processes and reloads configuration and binary modules

A simple and straightforward restart method:

Check the master process number of php-fpm first.

[root@test ~] # ps-ef | grep php-fpmroot 27556 1 0 15:57? 00:00:00 php-fpm: master process (/ usr/local/php/etc/php-fpm.conf) www 27557 27556 15:57? 00:00:00 php-fpm: pool www www 27558 27556 0 15:57? 00:00:00 php-fpm: pool www www 27559 27556 0 15:57? 00:00:00 php-fpm: pool www www 27560 27556 0 15:57? 00:00:00 php-fpm: pool www root 27733 26938 0 16:35 pts/0 00:00:00 grep php-fpm

Restart php-fpm:

Kill-USR2 27556

That's OK. [recommended: PHP video tutorial]

The above scenario is generally used when no php-fpm.pid file is generated. If you want to generate php-fpm.pid, use the following scenario:

As you can see from the master process above, matster uses the configuration file / usr/local/php/etc/php-fpm.conf, and cat / usr/local/php/etc/php-fpm.conf finds:

[global]; Pid file; Note: the default prefix is / usr/local/php/var; Default Value: none;pid = run/php-fpm.pid

The path of the pid file should be located in / usr/local/php/var/run/php-fpm.pid. It was not generated because it was commented out. If we remove the comments and restart php-fpm with kill-USR2 42891, the pid file will be generated. Next time, you can restart and close php-fpm using the following command:

Php-fpm shuts down:

Kill-INT 'cat / usr/local/php/var/run/php-fpm.pid'

Php-fpm restart:

Kill-USR2 'cat / usr/local/php/var/run/php-fpm.pid' are all the contents of this article entitled "what are the startup modes in php-fpm?" Thank you for reading!
