CentOS 添加nginx到系统服务(service)

1. 简介

nginx源码安装完成后默认不会注册为系统服务,所以需要手工添加系统服务脚本。在/etc/init.d目录下新建nginx文件,并更改权限其即可。

2. 新建nginx文件

vim /etc/init.d/nginx
填写一下内容(根据自己的实际目录修改):

3. 修改文件权限

1
chmod 755 /etc/init.d/nginx

4. 设置开机启动

1
chkconfig nginx on

5. 查看开机启动的服务

1
chkconfig --list

6. 备注

启动服务:service nginx start

停止服务:service nginx stop

重启服务:service nginx reload
