SHELL判断服务是不是正在运行

使用SHELL脚本进行检查服务开启情况

#!/bin/bash
#需要首先安装 yum install nmap -y

#检查指定端口是否开启
function checkPortStatus()
{
        status=`nmap -sS 127.0.0.1 -p $ | grep open | awk '{print $2}'`
        if [ "$status" != "open" ];
        then
                return ;
        else
                return ;
        fi
}

checkPortStatus
echo $?

checkPortStatus
echo $?
