Check the php configuration and restart php-fpm in nginx.

1. view the current php configuration information

Create the findini. php file in the root directory of the php project. The content is as follows:

<?php   phpinfo();?>

Visit the page to see the following page:

Search for Loaded Configuration File to find out which Configuration File php is currently using.

2. php-fpm restart and other operations

Php-fpm has been embedded in the source code of php 5.3.3. You do not need to install patches like in the previous php version. You only need to add the compilation parameters when configuring configure.
The compiling parameters for php-fpm include-enable-fpm-with-fpm-user = www-with-fpm-group = www-with-libevent-dir = libevent.
However, php-fpm in php 5.3.3 does not support commands such as/usr/local/php/sbin/php-fpm (start | stop | reload) in php 5.3.3, signal control is required:

The master process can understand the following signals:

INT, TERM terminated immediately
QUIT smooth termination
USR1 re-open the log file
USR2 smoothly reloads all worker processes and reloads configuration and binary modules.

Example:
Disable php-fpm:

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`

View the number of php-fpm processes:

ps aux | grep -c php-fpm

If the corresponding pid file cannot be found, you can find it as follows:

ps -aux|grep php-fpm

The main process is shown as follows:

root     12030  0.0  0.0 129360  4076 ?        Ss   18:35   0:00 php-fpm: master process (/usr/local/php/etc/php-fpm.conf)
