这个脚本，可以满足nginx开启，停止和重启的操作

#!/bin/bash

. /etc/init.d/functions

function usage() {
    echo $"usage:$0 {start|stop|restart}"
    exit 1
}

function start() {
    /usr/local/nginx/sbin/nginx 
    sleep 1
    if [ `netstat -antlpe | grep nginx | wc -l` -ge 0 ];then
	action "nginx is started." /bin/true 
    else
	action "nginx is started." /bin/false
    fi
}

function stop() {
    killall nginx &>/dev/null
    sleep 1
    if [ `netstat -antlpe | grep nginx | wc -l` -eq 0 ];then
	action "nginx is stopped." /bin/true
    else
	action "nginx is stopped." /bin/false
    fi
}

function main() {
    if [ $# -ne 1 ];then
	usage $0
    fi
    case $1 in 
	start)
	start
	;;
	stop)
	stop
	;;
	restart)
	stop
	start
	;;
	*)
	usage $0
	;;
    esac
}

main $*
