ipmitool命令的基本格式是:
ipmitool [选项] <命令> [参数]
其中,选项
是一些可选的开关,用于设置ipmitool的一些参数。命令
是要执行的操作,如获取传感器信息等。参数
是可选的,它们是指定要执行的特定操作所需的选项和值。
以下是一些常用的ipmitool命令:
ipmitool sensor get <Sensor ID>
其中,
是要获取的传感器的ID。此命令将显示指定传感器的当前状态。
ipmitool fru print
此命令将打印系统中所有可用的FRU(固件可重编程单元)信息。
ipmitool power on 开启电源
ipmitool power off 关闭电源
ipmitool power reset 重置电源,按我的理解是没有完全断电的动作,类似系统的reboot
ipmitool power cycle 先关闭电源,再开启
这些命令用于控制服务器的电源状态。
ipmitool sel list
此命令将显示系统的事件日志。
ipmitool user enable <用户ID>
ipmitool user disable <用户ID>
这些命令用于启用或禁用BMC用户。
以上是一些常用的ipmitool命令和它们的基本用法。更多的ipmitool命令和选项可以通过ipmitool -h
命令查看完整的帮助文档。
另外关于OS下设定BMC或远程控制服务器的BMC命令等:
ipmitool可以通过IPMI-over-LAN(基于LAN的IPMI协议)来远程控制BMC。要使用IPMI-over-LAN,您需要确保BMC已经配置并连接到网络。
下面是通过IPMI-over-LAN连接到BMC并进行远程控制的步骤:
使用ipmitool lan print
命令可以获取BMC的IP地址、MAC地址和子网掩码等信息。如果BMC未配置IP地址,则需要在本地物理访问服务器以配置BMC。
使用ipmitool lan set <参数>
命令设置BMC的用户名、密码和IP地址等信息。例如,下面的命令设置BMC的IP地址为192.168.1.100,并将用户名设置为admin,密码设置为password:
ipmitool lan set 1 ipsrc static
ipmitool lan set 1 ipaddr 192.168.1.100
ipmitool lan set 1 netmask 255.255.255.0
ipmitool lan set 1 defgw ipaddr 192.168.1.1
ipmitool user set name 2 admin
ipmitool user set password 2 password
注意,这里假设BMC使用的是默认的LAN通道1。如果使用的是其他通道,则需要将1
替换为相应通道的数字。
使用ipmitool channel info <通道号>
命令检查BMC所在通道的IPMI-over-LAN功能是否已经启用。如果未启用,可以使用以下命令启用:
ipmitool channel setaccess <通道号> 2 ipmi=on auth=off link=on privilege=4
这将启用指定通道的IPMI-over-LAN功能,并使得通过此通道的IPMI会话的权限级别为4(ADMINISTRATOR级别)。
使用以下命令连接到远程BMC:
ipmitool -H <BMC IP地址> -U <用户名> -P <密码> -I lanplus <命令>
注意,这里使用了-I lanplus
选项,以使用基于LAN的IPMI协议。<命令>
是您要执行的ipmitool命令。例如,要获取传感器信息,可以使用以下命令:
ipmitool -H 192.168.1.100 -U admin -P password -I lanplus sensor list
这将显示远程BMC的传感器列表信息。
以上是通过ipmitool进行远程BMC控制的基本步骤。请注意,远程BMC的访问权限应该是受限的,只有授权用户才能访问。此外,您还应该确保网络安全措施已经得到了应用,以确保远程访问的安全性。
