CentOS安装ipmi

CentOS release 6.2 (Final)
一、安装所需软件
1、查询下ipmi安装包
yum list |grep ipmi
ipmitool.x86_64 1.8.11-13.el6.1 @updates
ipmitool.x86_64 1.8.11-14.el6_4.1 update
2、安装ipmitool
yum -y install ipmitool
3、查看已安装的ipmi包
rpm -qa |grep ipmi
ipmitool-1.8.11-13.el6.1.x86_64
4、将ipmi服务添加到启动项
chkconfig ipmi on
5、5.1和5.2二选一查看
5.1)、ls /etc/rc3.d/S13ipmi
lrwxrwxrwx 1 root root 14 May 6 16:26 /etc/rc3.d/S13ipmi -> ../init.d/ipmi
5.2)、chkconfig –list|grep ipmi
ipmi 0:off 1:off 2:on 3:on 4:on 5:on 6:off
6、加载ipmi模块
modprobe ipmi_si && modprobe ipmi_devintf && modprobe ipmi_msghandler
7、查看模块
lsmod |grep ipmi
ipmi_si 42401 0
ipmi_devintf 8049 0
ipmi_msghandler 35992 2 ipmi_si,ipmi_devintf
8、启动ipmi
/etc/init.d/ipmi start

二、配置grub启动参数
cat /boot/grub/grub.conf|egrep -v “^#|^$”
default=0
timeout=5
title CentOS (2.6.32-220.el6.x86_64)
root (hd0,0)
kernel /boot/vmlinuz-2.6.32-220.el6.x86_64 ro root=/dev/sda1 selinux=0 console=tty0 console=ttyS1,115200 ro
initrd /boot/initramfs-2.6.32-220.el6.x86_64.img
PS:添加console=tty0 console=ttyS1,115200在这个配置文件里
console=tty0 console=ttyS1,115200参数传递到内核中,实现串口重定向
console=tty0 代表显示器输出
console=ttyS0 代表定向到串口1 ,如果是ttyS1代表定向到串口2
115200则为串口通信采用的波特率,波特率和bios设置的一样

三、通过ipmitool命令还可以对ipmi进行配置
1、查看ipmi信息
ipmitool lan print 1
2、设置BMC ip,作为远程管理ip
ipmitool lan set 1 ipaddr 172.16.*.*
3、连接目标终端
ipmitool -I lanplus -H 172.16.1. -U root -P 123456 sol activate
4、结束目标终端
ipmitool -I lanplus -H 172.16.1. -U root -P 123456 sol deactivate
5、重启目标终端
ipmitool -Ilanplus -H 172.16.1. -U root -P 123456 power reset
6、查看电源情况
ipmitool -I lanplus -H 172.16.1. -U root -P 123456 power status
7、开机
ipmitool -I lanplus -H 172.16.1. -U root -P 123456 power on
8、关机
ipmitool -I lanplus -H 172.16.1. -U root -P 123456 power off
9、修改bios启动项为网络启动
ipmitool -I lanplus -H 172.16.1. -U root -P 123456 chassis bootdev pxe
10、设置channel 1允许访问
ipmitool -I open lan set 1 access on
11、配置ipmi管理用户
ipmitool user set name 2 root
ipmitool user set password 2 “123456”
12、获取传感器中的各种监测值和该值的监测阈值,包括(CPU温度,电压,风扇转速,电源调制模块温度,电源电压等信息)
ipmitool -I open sdr list(ipmitool -I open sensor)
13、显示温度
ipmitool sdr type Temperature
Temp | 01h | ok | 3.1 | -56 degrees C
Temp | 02h | ok | 3.2 | 50 degrees C
Temp | 05h | ok | 10.1 | 42 degrees C
Temp | 06h | ns | 10.2 | Disabled
Ambient Temp | 0Eh | ok | 7.1 | 20 degrees C
Planar Temp | 0Fh | ok | 7.1 | 37 degrees C
CPU Temp IF | 76h | ns | 7.1 | Disabled
Temp | 0Ah | ok | 8.1 | 31 degrees C
Temp | 0Bh | ns | 8.1 | Disabled
Temp | 0Ch | unc | 8.1 | 45 degrees C
Ambient Temp | 07h | ok | 10.1 | 29 degrees C
Ambient Temp | 08h | ns | 10.2 | Disabled
当然也可以ipmitool sdr type直接回车
ipmitool sdr type
Sensor Types:
Temperature Voltage
Current Fan
Physical Security Platform Security
Processor Power Supply
Power Unit Cooling Device
Other Memory
Drive Slot / Bay POST Memory Resize
System Firmwares Event Logging Disabled
Watchdog System Event

14、退出ipmi
shift ~ .

ipmitool命令参数说明
lan用于远程访问,电源管理等。 open用于本地访问。 lanplus用于sol。

三、inittab配置(因版本不同 配置有相应的变动)
cat /etc/inittab|egrep -v “^#|^$”
co:2345:respawn:/sbin/agetty ttyS1 115200 vt100-nav
设置ipmi必须需要注意 有的时候是ttyS1有的时候ttyS0 根据情况更改ttyS1还是ttyS0
/etc/inittab如何生效?
生效的话需要执行init q(Q or q tell init to re-examine the /etc/inittab file. )
ps aux|grep tty
root 1137 0.0 0.0 4072 228 ttyS1 Ss+ 2013 0:00 /sbin/agetty /dev/ttyS1 115200 vt100-nav
或执行start ttyS1
