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
Temp             | 01h | ns  |  3.1 | Disabled
Temp             | 02h | ns  |  3.2 | Disabled
Temp             | 05h | ns  | 10.1 | Disabled
Temp             | 06h | ns  | 10.2 | Disabled
Ambient Temp     | 0Eh | ok  |  7.1 | 22 degrees C
Planar Temp      | 0Fh | ns  |  7.1 | Disabled
IOH THERMTRIP    | 5Dh | ns  |  7.1 | Disabled
CPU Temp Interf  | 76h | ns  |  7.1 | Disabled
Temp             | 0Ah | ns  |  8.1 | Disabled
Temp             | 0Bh | ns  |  8.1 | Disabled
Temp             | 0Ch | ns  |  8.1 | Disabled

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。

实例

  cpu负载:

[root@m02 ~]# uptime 
 09:11:40 up 18:35,  1 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:   1.0G          0B        1.0G

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
