IPMI(Intelligent Platform Management Interface)智能平台管理接口 是一种开放标准的硬件管理接口规格,定义了嵌入式管理子系统进行通信的特定方法。IPMI亦是一个开放的免费标准,用户无需支付额外的费用即可使用此标准。
IPMI 能够横跨不同的操作系统、固件和硬件平台,可以智能的监视、控制和自动回报大量服务器的运作状况,以降低服务器系统成本。
PMI的核心是一个专用芯片/控制器 —— BMC,其并不依赖于服务器的处理器、BIOS或操作系统来工作,可谓非常地独立。
在工作时,所有的IPMI功能都是向BMC发送命令来完成的,BMC接收并在系统事件日志中记录事件消息,维护描述系统中传感器情况的传感器数据记录。
最简单的话理解,就是BMC是独立于整个系统之外的一个设备,它不依赖于运行的系统,就好像一个外挂模块,有自己的网络,并且断电都不会影响它。它可以从外部管理服务器。
远程调整BIOS;
远程安装操作系统;
在遥远的地方,我们不需要去机房,直接通过ipmi的命令工具即可进行对服务器电源的操作 —— 这个操作是独立于操作系统的,硬件实现,因此比较稳定可靠。
在Linux环境下我们可以通过 ipmi的命令行工具,来进行服务器硬件的获取:例如:风扇的转速,机箱温度,硬件日志,电压,BIOS版本号,RAID卡 fireware版本号,机箱上次打开的时间,服务标签等等。
yum install OpenIPMI OpenIPMI-tools
chkconfig ipmi on
service ipmi start
modprobe ipmi_watchdog
modprobe ipmi_poweroff
modprobe ipmi_devintf
modprobe ipmi_si
modprobe ipmi_msghandler
然后就可以用ipmitool命令了
[root@localhost ~]# ipmitool

例子
[root@localhost ~]# ipmitool -I open power status
Chassis Power is on
首先需要配置IPMI的IP地址
ipmitool lan set 1 ipsrc static
ipmitool lan set 1 ipaddress 192.168.1.239
ipmitool lan set 1 netmask 255.255.255.0
ipmitool lan set 1 defgw ipaddr 192.168.1.1
ipmitool lan print 1
[root@localhost home]# ipmitool lan print 1
Set in Progress : Set Complete
Auth Type Support : MD5
Auth Type Enable : Callback : MD5
: User : MD5
: Operator : MD5
: Admin : MD5
: OEM : MD5
IP Address Source : Static Address
IP Address : 192.168.1.239
Subnet Mask : 255.255.255.0
MAC Address : b4:05:5d:a2:8f:00
SNMP Community String : AMI
IP Header : TTL=0x40 Flags=0x40 Precedence=0x00 TOS=0x10
BMC ARP Control : ARP Responses Enabled, Gratuitous ARP Disabled
Gratituous ARP Intrvl : 0.0 seconds
Default Gateway IP : 192.168.1.1
Default Gateway MAC : 68:ed:a4:3b:94:e1
Backup Gateway IP : 0.0.0.0
Backup Gateway MAC : 00:00:00:00:00:00
802.1q VLAN ID : Disabled
802.1q VLAN Priority : 0
RMCP+ Cipher Suites : 0,1,2,3,6,7,8,11,12,15,16,17
Cipher Suite Priv Max : caaaaaaaaaaaXXX
: X=Cipher Suite Unused
: c=CALLBACK
: u=USER
: o=OPERATOR
: a=ADMIN
: O=OEM
Bad Password Threshold : 3
Invalid password disable: no
Attempt Count Reset Int.: 200
User Lockout Interval : 300
然后增加用户2,名字为root
ipmitool user set name 2 root
ipmitool user set password 2 123456
ipmitool user priv 2 0x4 1
ipmitool user enable 2
[root@localhost home]# ipmitool user list 1
ID Name Callin Link Auth IPMI Msg Channel Priv Limit
1 admin true true true ADMINISTRATOR
2 root true true true ADMINISTRATOR
3 true false false NO ACCESS
4 true false false NO ACCESS
5 true false false NO ACCESS
6 true false false NO ACCESS
7 true false false NO ACCESS
8 true false false NO ACCESS
9 true false false NO ACCESS
10 true false false NO ACCESS
11 true false false NO ACCESS
12 true false false NO ACCESS
13 true false false NO ACCESS
14 true false false NO ACCESS
15 true false false NO ACCESS
16 true false false NO ACCESS
然后配置绑定到channle 1
ipmitool channel setaccess 1 2 callin=on
ipmitool channel setaccess 1 2 ipmi=on
ipmitool channel setaccess 1 2 link=on
ipmitool channel setaccess 1 2 privilege=4
然后在另一台机器上,安装好ipmitool工具。
[root@localhost ~]# ipmitool -I lanplus -H 192.168.1.239 -U root -P 123456 power status
Chassis Power is on
这是常见的命令部分,完整命令需要后续的部分,每个部分都不一样,需要随用随学。
