Centos7 php-fpm root 运行，执行 kill 等系统命令

Centos7 php-fpm root 运行，执行 kill 等系统命令

前提

当前系统安装的是宝塔环境，PHP的环境在如下的目录：

/www/server/php/72/etc

1 修改 php-fpm.conf

php-fpm 的用户和组改成 root

[global]
pid = /www/server/php//var/run/php-fpm.pid
error_log = /www/server/php//var/log/php-fpm.log
log_level = notice

[www]
listen = /tmp/php-cgi-.sock
listen.backlog = -
listen.allowed_clients = 127.0.0.1
listen.owner = www
listen.group = www
listen.mode =
user = root
group = root
pm = dynamic
pm.status_path = /phpfpm_72_status
pm.max_children =
pm.start_servers =
pm.min_spare_servers =
pm.max_spare_servers =
request_terminate_timeout =
request_slowlog_timeout =
slowlog = var/log/slow.log

2 kill 当前运行进程

killall php-fpm

3 启动 php-fpm

php-fpm -R

4 测试

如果需要在web执行系统命令，使用如下代码：

shell_exec("sudo service network restart");

5 宝塔配置

如果您的安装环境中是用宝塔安装的，那么需要修改对应的启动脚本，我当前使用的是PHP7.2版本；故修改 /etc/init.d/php-fpm-72

vi /etc/init.d/php-fpm-72

#! /bin/sh

### BEGIN INIT INFO
# Provides:          php-fpm
# Required-Start:    $remote_fs $network
# Required-Stop:     $remote_fs $network
# Default-Start:
# Default-Stop:
# Short-Description: starts php-fpm
# Description:       starts the PHP FastCGI Process Manager daemon
### END INIT INFO
