如果想远程管理服务器就有远程管理卡，比如Dell idRAC，HP ILO，IBM IMM
查看硬件的温度/风扇转速，电脑有撸大师，服务器就有ipmitool。使用ipmitool实现对服务器的命令行远程管理
yum -y install OpenIPMI ipmitool #->IPMI在物理机可以成功，虚拟机不行
[root@KVM ~]# ipmitool sdr type Temperature

查看cpu方面
想知道了cpu性能好不好、忙不忙可以用lscpu、uptime、top、htop。

cpu负载：
[root@m02 ~]# uptime
:: up :, user, load average: 0.00, 0.05, 0.05
查看内存方面
内存够不够可以用free
[root@cache01 ~]# free -h
total used free shared buff/cache available
Mem: 472M 105M 93M 4.8M 272M 325M
Swap: .0G 0B .0G
查看磁盘相关
磁盘剩多少写的快不快可以用df、dd、iotop
[root@m01 ~]# yum install iotop -y
[root@m01 ~]# iotop
