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下安裝后，如何設置開機自啟動。
首先，在linux系統的/etc/init.d/目錄下創建nginx文件，使用如下命令：
vi /etc/init.d/nginx
在腳本中添加如下命令：
*********************************************************************************************************************************
#!/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
*********************************************************************************************************************************
注意紅色加粗部分，需要將路徑改為自己機器的相應路徑。
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 所有用戶可執行)
最后將ngix加入到rc.local文件中，這樣開機的時候nginx就默認啟動了
vi /etc/rc.local
添加
/etc/init.d/nginx start
保存並退出
下次重啟就會生效，實現nginx的自啟動。
