通过shell完成服务器巡检 输出服务器基础信息(内存CPU磁盘 Nginx redis mysql jar包）的状态.

#!/bin/bash
#获取服务器cpu信息
cpu=$(top -bn5 |awk -F " " '/Cpu/{print $2"%"}')

#获取服务器内存信息
free=$(free -h | awk -F " " '/Mem/{print $7}')

#获取服务器磁盘信息
#/vd/是云主机的磁盘格式,虚拟机物理机可替换为/sd/
disk=$(df -h | awk -F " " '/vd/{print $1"   "$5}')

#时间
date=$(date +%Y-%m-%d" "%H:%M)
