Nginx使用（配置开机启动）

环境：

　　系统：CentOS 6.5 Final

　　安装目录：/usr/local/nginx

Nginx开机自启：

①编写shell实现控制

vi /etc/init.d/nginx

添加内容：

#!/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 

更改访问权限：

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

测试效果：

[[email protected] ~]# /etc/init.d/nginx stop

停止 nginx：                                               [确定]

[[email protected] ~]# /etc/init.d/nginx start

正在启动 nginx：                                           [确定]

[[email protected] ~]# /etc/init.d/nginx restart

停止 nginx：                                               [确定]

正在启动 nginx：                                           [确定]

[[email protected] ~]# /etc/init.d/nginx stop

停止 nginx：                                               [确定]

[[email protected] ~]# /etc/init.d/nginx sto

Usage: nginx {start|stop|restart|reload|status|help}

[[email protected] ~]# /etc/init.d/nginx restart

停止 nginx：                                               [失败]

正在启动 nginx：                                           [确定]

②使用该shell配置开机启动

法一：

vi /etc/rc.local

添加一行

/etc/init.d/nginx start 

保存并退出，重启生效。

法二：

chkconfig --add nginx //添加索引

chkconfig --level 23 nginx on //开机启动

重启生效。

③添加自定义命令（使用nginx代替/etc/init.d/nginx，启动nginx再也不用输那么长命令了）

vi  /root/.bashrc

追加

alias nginx="/etc/init.d/nginx"

重启生效。
