centos ngnix 自动启动

编写脚本

1	[root@localhost]# vim /etc/init.d/nginx

如下是脚本内容

#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# it is v.0.0.2 version.
# chkconfig: - 85 15

[ -x $nginxd ] || exit 0

start() {

  echo "nginx already running...."
  exit 1

  echo -n $"Starting $prog: "
  daemon $nginxd -c ${nginx_config}
  RETVAL=$?
  echo
  [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx
  return $RETVAL
}
# Stop nginx daemons functions.
stop() {
    echo -n $"Stopping $prog: "
    killproc $nginxd
    RETVAL=$?
    echo
    [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /usr/local/nginx/logs/nginx.pid
}
# reload nginx service functions.

  echo -n $"Reloading $prog: "
  #kill -HUP `cat ${nginx_pid}`

:wq 保存并退出

 

保存脚本文件后设置文件的执行权限：

chmod a+x /etc/init.d/nginx

而后，就能够经过该脚本对nginx服务进行管理了：

/etc/init.d/nginx start
/etc/init.d/nginx stop

使用chkconfig进行管理

上面的方法完成了用脚本管理nginx服务的功能，可是仍是不太方便，好比要设置nginx开机启动等。这时能够使用chkconfig来设置。

先将nginx服务加入chkconfig管理列表：

chkconfig --add /etc/init.d/nginx

加完这个以后，就能够使用service对nginx进行启动，重启等操做了。

service nginx start
service nginx stop

设置终端模式开机启动：

chkconfig nginx on
