运维篇—Nginx的快速启动停止Shell脚本

通常我们在编译安装的nginx由于没有提供nginx服务的管理脚本，在启动、停止以及重启nginx时非常不方便。只能通过安装的sbin目录下执行 nginx， nginx -s stop/reload。所以自己写了一个shell脚本来操作，也是在公司生产环境中使用。（centos系统）。

1.把脚本复制到/etc/init.d/目录下，命名为nginx，并赋予可执行权限

cd /etc/init.d/

chmod +x nginx

2.修改脚本中安装目录

3.常用使用命令

service nginx start 启动nginx

service nginx stop 停止nginx

service nginx restart 重启nginx

service nginx relaod 平滑重启nginx

4.脚本代码

#! /bin/bash

# nginx - this script starts and stops the nginx daemon

# chkconfig: - 85 15

# description: nginx shell

# processname: nginx

# config: /etc/nginx/nginx.conf

# pidfile: /var/run/nginx/nginx.pid

# Source function library.

. /etc/rc.d/init.d/functions

# Source networking configuration.

. /etc/sysconfig/network

# Check that networking is up.

[ "$NETWORKING" = "no" ] && exit 0
