＊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
