虚拟机设置Nginx的开机自动启动(脚本启动)

7.1 编写**shell脚本**(这里使用的是编写shell脚本的方式来处理)  
(输入下面的代码)

vim /etc/init.d/nginx

#!/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

:wq 保存并退出

7.2 设置文件的访问权限 (a+x ==> all user can execute 所有用户可执行)

chmod a+x /etc/init.d/nginx

这样在控制台就很容易的操作nginx了：  
查看Nginx当前状态:

/etc/init.d/nginx status

启动Nginx:

/etc/init.d/nginx start

停止Nginx:

/etc/init.d/nginx stop

重启Nginx(或者命令:/etc/init.d/nginx reload)…:

/etc/init.d/nginx restart

如果修改了nginx的配置文件nginx.conf，也可以使用上面的命令重新加载新的配置文件并运行，可以将此命令加入到rc.local文件中，这样开机的时候nginx就默认启动了

7.3 加入到rc.local文件中:

vim /etc/rc.local

加入一行以下内容,保存并退出，下次重启会生效(reboot)。

/etc/init.d/nginx start
