Linux(CentOS)系統下設置nginx開機自啓動

Nginx 是一個很強大的高性能Web和反向代理服務器。下面介紹在linux下安裝後，如何設置開機自啓動。
首先，在linux系統的/etc/init.d/目錄下建立nginx文件，使用以下命令：
vi /etc/init.d/nginx

在腳本中添加以下命令：
*********************************************************************************************************************************

#!/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

*********************************************************************************************************************************
注意紅色加粗部分，須要將路徑改成本身機器的相應路徑。
接着，設置文件的訪問權限：
chmod a+x /etc/init.d/nginx                                                        (a+x參數表示 ==> all user can execute  全部用戶可執行)

最後將ngix加入到rc.local文件中，這樣開機的時候nginx就默認啓動了

vi /etc/rc.local

添加

/etc/init.d/nginx start   

保存並退出

下次重啓就會生效，實現nginx的自啓動。
