＊Nginx 安装完后，开启，关闭的操作实在是长，因此……

一、新建脚本:

$ vi /etc/init.d/nginx

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemin
#
# chkconfig:   - 85 15 
# description:  Nginx is an HTTP(S) server, HTTP(S) reverse \
#               proxy and IMAP/POP3 proxy server
# processname: nginx
# config:      /etc/nginx/nginx.conf
# pidfile:     /run/nginx/nginx.pid
# Source function library.
. /etc/rc.d/init.d/functions

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ "$NETWORKING" = "no" ] && exit 0

nginx="/usr/sbin/nginx"

prog=$(basename $nginx)

NGINX_CONF_FILE="/etc/nginx/nginx.conf"

lockfile=/var/lock/nginx.lock

start() {
    [ -x $nginx ] || exit 5
    [ -f $NGINX_CONF_FILE ] || exit 6
    echo -n $"Starting $prog: "
    daemon $nginx -c $NGINX_CONF_FILE
    retval=$?
    echo
    [ $retval -eq 0 ] && touch $lockfile
    return $retval
}

stop() {
    echo -n $"Stopping $prog: "
    killproc $prog -QUIT
    retval=$?
    echo
    [ $retval -eq 0 ] && rm -f $lockfile
    return $retval
}

restart() {
    configtest || return $?
    stop
    start
}

reload() {
    configtest || return $?
    echo -n $"Reloading $prog: "
    killproc $nginx -HUP
    RETVAL=$?
    echo
}

force_reload() {
    restart
}

configtest() {
  $nginx -t -c $NGINX_CONF_FILE
}

rh_status() {
    status $prog
}

rh_status_q() {
    rh_status >/dev/null 2>&1
}

case "$1" in
    start)
        rh_status_q && exit 0
        $1
        ;;
    stop)
        rh_status_q || exit 0
        $1
        ;;
    restart|configtest)
        $1
        ;;
    reload)
        rh_status_q || exit 7
        $1
        ;;
    force-reload)
        force_reload
        ;;
    status)
        rh_status
        ;;
    condrestart|try-restart)
        rh_status_q || exit 0
            ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}"
        exit 2
esac

注意几个地方的配置，就是上在nginx中编译时设置的那些目录：

# config: /etc/nginx/nginx.conf

# pidfile: /run/nginx/nginx.pid

nginx="/usr/sbin/nginx"

NGINX_CONF_FILE="/etc/nginx/nginx.conf"

lockfile=/var/lock/nginx.lock

二、添加到服务

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

$ chkconfig --add nginx

$ chkconfig --list nginx
nginx          	0:关	1:关	2:关	3:关	4:关	5:关	6:关

上面其实就是在／etc/rc.d/rc5.d/目录下创建了一个链接。如下：

$ cd /etc/rc.d/rc5.d/

$ ll |grep nginx
lrwxrwxrwx. 1 root root 15 6月  24 16:14 K15nginx -> ../init.d/nginx

三、使用

$ service nginx start  
$ service nginx stop  
$ service nginx restart  
$ service nginx reload  
  
$ /etc/init.d/nginx start  
$ /etc/init.d/nginx stop  
$ /etc/init.d/nginx restart  
$ /etc/init.d/nginx reload

四、问题：

如果有下面的错误提示，去看看目录是否在该文件，如果实在是存在，且脚本无错，则考虑文件的格式是不是正确，网上有用工具转的比如:doc2unix 。

env: /etc/init.d/nginx: 没有那个文件或目录

我的做法是直接复制下内容:

$ rm /etc/init.d/nginx

$ vi /etc/init.d/nginx

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