cobbler之电源管理

电源管理

8.1 测试机环境

DELL系统CentOS5.8 64bit安装ipmitoolyum install ipmitool -y8.2 安装电源管理工具cmanyum install cman -yCobbler代码维护者jimi告知：某些系统版本将执行程序安装在/sbin/目录下，通过rpm -ql cman查看，CentOS5.8下如此解决即可ln -s /sbin/fence_* /usr/sbin/

8.3 修改电源管理python脚本

备份cp /usr/lib/python2.4/site-packages/cobbler/action_power.py /usr/lib/python2.4/site-packages/cobbler/action_power.py.$(date +%F)编辑vim /usr/lib/python2.4/site-packages/cobbler/action_power.py 删除或注释此文件如下代码utils.die(self.logger,"command succeeded (rc=%s), but output ('%s') was not understood" % (rc, output))删除文件action_power.pyo 、 action_power.pyc这两个文件在目录/usr/lib/python2.4/site-packages/cobbler/下重启cobbler，注意一定是重启cobblercobbler reboot步骤8.2、8.3是我在使用电源管理中发现的问题，后通过github与Cobbler代码维护者jimi沟通解决的，非常感谢他的帮助，详见https://github.com/cobbler/cobbler/issues/4268.4 配置电源管理参数为指定的系统配置host-188116增加电源管理参数cobbler system edit --name=host-188116 --power-address=172.17.11.20 --power-type='ipmilan' --power-user=root --power-pass=djxxxx

8.5 检查、同步配置

8.6 查看配置信息

cobbler system report | egrep -i "system|profile|power"Power Management Address : 172.17.11.20Power Management ID :Power Management Password : djxxxxPower Management Type : ipmilanPower Management Username : rootProfile : centos5.8-x86_64

8.7 Cobbler默认的电源管理配置

/etc/cobbler/settings# settings for power management features. optional.# see https://github.com/cobbler/cobbler/wiki/Power-management to learn more# choices (refer to codes.py):# apc_snmp bladecenter bullpap drac ether_wake ilo integrity# ipmilan ipmitool lpar rsa virsh wtipower_management_default_type: 'ipmitool' # the commands used by the power management module are sourced# from what directory?power_template_dir: "/etc/cobbler/power"
