Linux设置nginx开机自启

1.首先进入/etc/init.d目录:

2.创建nginx服务配置文件:vi nginx

3.将以下代码复制到创建的 nginx 配置文件中:

#!/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

注意检查里面的相对路径要改成和自己的一致

4.按下esc输入:wq! 保存并退出

5.给文件设置访问权限:chmod a+x /etc/init.d/nginx

6.添加 nginx 为系统服务:chkconfig --add nginx

7.输入命令查看是否添加成功: chkconfig --list
在这里插入图片描述
2,3,4,5都是开代表跟随系统而启动

8.要想管理这些服务的开关可以通过ntsysv命令
(1)ntsysv --level 2345 这样就可以对这几个开关进行打开和关闭了
(如果没有这个命令可以通过 yum install ntsysv 命令来下载)
在这里插入图片描述
(2)可以进入到一个这个图形界面 *代表打开 空白代表关闭 (空格建切换模式)
(3)如果其他自启文件配置开启自启的话chkconfig里面将不起作用
