PHP-FPM启动脚本

编写初衷：

因为某些原因会经常重启php。但每次 都会提示端口被暂用。

[root@localhost ~]# /opt/php-7.1.11/sbin/php-fpm 
[29-Aug-2018 15:11:29] ERROR: unable to bind listening socket for address '127.0.0.1:9000': Address already in use (98)
[29-Aug-2018 15:11:29] ERROR: FPM initialization failed

只能每次kill掉进程，然后再启动，这样操作很麻烦。

 

 

创建/etc/init.d/php-fpm，并赋权

[root@localhost ~]# cd /etc/init.d/
[root@localhost init.d]# touch php-fpm
[root@localhost init.d]# chmod +x php-fpm

/etc/init.d/php-fpm文件内容

#! /bin/sh
