公司的生产环境中,大部分都是DELL系列(1950 2950 410 420 510 610 710 720等) 都配置DRAC远程控制卡来支持IPMI，并分配了特定的网络段IP(172.16.0.0/24)给每台服务器 这样，平时我们远程修改BIOS启动项，重启服务器，连接本地终端等操作就都可以通过IPMI来实现了。 https://www.thomas-krenn.com/en/wiki/Configuring_IPMI_under_Linux_using_ipmitool参考文档 ================================Debian====================================== cat /etc/debian_version 5.0.2 一、安装所需软件 1、查询下ipmi安装包 apt-cache search ipmi ipmitool - utility for IPMI control with kernel driver or LAN interface 2、安装ipmitool apt-get -y install ipmitool --force-yes 3、查看已安装的ipmi包 dpkg -l|grep ipmi ii ipmitool 1.8.9-2 utility for IPMI control with kernel driver or LAN interface 4、将ipmivd服务添加到启动项 update-rc.d ipmievd defaults 5、5.1和5.2二选一查看 5.1)、ls /etc/rc2.d/S20ipmievd lrwxrwxrwx 1 root root 17 2014-12-28 11:32 /etc/rc2.d/S20ipmievd -> ../init.d/ipmievd 5.2)、sysv-rc-conf --list |grep ipmi ipmievd 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 43656 0 ipmi_devintf 15632 0 ipmi_msghandler 40308 2 ipmi_si,ipmi_devintf 二、配置grub启动参数 cat /boot/grub/menu.lst|egrep -v "^#|^$" default 2 timeout 5 color cyan/blue white/blue title Debian GNU/Linux, kernel 2.6.26-2-amd64 root (hd0,0) kernel /boot/vmlinuz-2.6.26-2-amd64 root=/dev/sda1 console=tty0 console=ttyS1,115200 ro initrd /boot/initrd.img-2.6.26-2-amd64 title Debian GNU/Linux, kernel 2.6.26-2-amd64 (single-user mode) root (hd0,0) kernel /boot/vmlinuz-2.6.26-2-amd64 root=/dev/sda1 console=tty0 console=ttyS1,115200 ro single initrd /boot/initrd.img-2.6.26-2-amd64 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 Critical Interrupt Button Module / Board Microcontroller Add-in Card Chassis Chip Set Other FRU Cable / Interconnect Terminator System Boot Initiated Boot Error OS Boot OS Critical Stop Slot / Connector System ACPI Power State Watchdog Platform Alert Entity Presence Monitor ASIC LAN Management Subsystem Health Battery Session Audit Version Change FRU State 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 "^#|^$" T1:23:respawn:/sbin/getty -L ttyS1 115200 vt100 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?
