Linux(CentOS)系统下设置nginx开机自启动  

Nginx 是一个很强大的高性能Web和 反向代理服务器。下面介绍在linux下安装后,如何设置开机自启动。
首先,在linux系统的 /etc/init.d/目录下创建nginx文件,使用如下命令:
vi /etc/init.d/nginx

在脚本中添加如下命令:
*********************************************************************************************************************************

#!/bin/bash

# nginx Startup script for the Nginx HTTP Server

# it is v.0.0.2 version.

# chkconfig: - 85 15

# description: Nginx is a high-performance web and proxy server.

#              It has a lot of features, but it‘s not for everyone.

# processname: nginx

# pidfile: /var/run/nginx.pid

# config: /usr/local/nginx/conf/nginx.conf

nginxd=/usr/local/nginx/sbin/nginx

nginx_config=/usr/local/nginx/conf/nginx.conf

nginx_pid=/var/run/nginx.pid

RETVAL=0

prog="nginx"

# Source function library.

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

# Source networking configuration.

. /etc/sysconfig/network

# Check that networking is up.

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

[ -x $nginxd ] || exit 0

# Start nginx daemons functions.

start() {

if [ -e $nginx_pid ];then

   echo "nginx already running...."

   exit 1

fi

   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 /var/run/nginx.pid

}

# reload nginx service functions.

reload() {

    echo -n $"Reloading $prog: "

    #kill -HUP `cat ${nginx_pid}`

    killproc $nginxd -HUP

    RETVAL=$?

    echo

}

# See how we were called.

case "$1" in

start)

        start

        ;;

stop)

        stop

        ;;

reload)

        reload

        ;;

restart)

        stop

        start

        ;;

status)

        status $prog

        RETVAL=$?

        ;;

*)

        echo $"Usage: $prog {start|stop|restart|reload|status|help}"

        exit 1

esac

exit $RETVAL


*********************************************************************************************************************************
注意红色加粗部分,需要将路径改为自己机器的相应路径。
接着,设置文件的访问权限:
chmod a+x /etc/init.d/nginx                                                         (a+x参数表示 ==> all user can execute  所有用户可执行)

最后将ngix加入到rc.local文件中,这样开机的时候nginx就默认启动了

vi /etc/rc.local

添加

/etc/init.d/nginx start   

保存并退出

下次重启就会生效,实现nginx的自启动。
