3, php configuration

#php的配置文件为 php.ini
cp /usr/local/php-7.1.4/php.ini-production   /usr/local/php/lib/php.ini
#使得另一种方法来管理服务：
cp /usr/local/php-7.1.4/sapi/fpm/php-fpm /etc/init.d/php-fpm
#添加执行权限
chmod +x /etc/init.d/php-fpm 
#php-fpm的配置文件
cp /usr/local/php/etc/php-fpm.conf.default   /usr/local/php/etc/php-fpm.conf
cp /usr/local/php/etc/php-fpm.d/www.conf.default   /usr/local/php/etc/php-fpm.d/www.conf

Modify the maximum limit on the number of php-fpm processes according to the machine configuration, which is limited to /usr/local/php/etc/php-fpm.d/www.conf

Use netstat -napo |grep " php-fpm" | wc -l Check the current number of fastcgi processes. If the number is close to the upper limit configured in conf, you need to increase the number of processes.

But you can’t increase it endlessly. You can adjust the number of php-fpm sub-processes to 100 or more according to the server memory. On a server with 4G memory, 200 is enough.

pm.max_children = 200
pm.start_servers = 10
pm.min_spare_servers = 8
pm.max_spare_servers = 12

4. Set environment variables

vi /etc/profile

After opening, add the following configuration at the bottom of the document:

export PATH=/usr/local/php/bin:$PATH
:wq!保存退出，执行如下命令，使更改生效
source /etc/profile

5. Start php test

#启动
/etc/init.d/php-fpm start
#测试php
cd /usr/local/nginx/html
vi test.php

Add the following content:

<?php  
 echo phpinfo();  
?>

:wq! Save and exit.

Browser input: http://10.62.32.123/test.php

If the PHP Version 7.1.4 interface appears, the detailed configuration interface of PHP is displayed, indicating that the installation is correct

6. Restart and stop php

php 7.1.4 The source code has already embedded php-fpm, you only need to add compilation parameters when configure.

The compilation parameters for php-fpm include –enable-fpm –with-fpm-user=www –with-fpm-group=www –with-libevent-dir=libevent location.

However, php-fpm under php 7.1.4 no longer supports commands such as /usr/local/php/sbin/php-fpm (start|stop|reload) that php-fpm previously had. You need to use Signal control:

The master process can understand the following signals:

SIGINT, SIGTERM Terminate immediately

SIGQUIT Terminate smoothly

SIGUSR1 Reopen the log file

SIGUSR2 Smoothly reload all worker processes and reload configuration and binary modules

Example:

php-fpm 关闭：  
kill -SIGINT `cat /usr/local/php/var/run/php-fpm.pid`  
php-fpm 重启：  
kill -SIGUSR2 `cat /usr/local/php/var/run/php-fpm.pid`

View the number of php-fpm processes:

ps aux | grep -c php-fpm
netstat -anpo | grep "php-cgi" | wc -l
netstat -anop | grep "php-fpm" | wc -l

3. Appendix
