一个openstack新增加计算节点的脚本。

2019-04-18 16:56:29  阅读：220  来源： 互联网

标签：脚本 file name nova echo conf openstack 节点 neutron


主要有四个文件：
1）addcomputernode.sh，主要脚本。在centos7 hpdl580 测试过。
2）addcomputernode.conf，一些配置信息，每个节点不同，都要改。第一次不能只修改这个，下面conf也有要改的。
3）nova.conf，这个是yum安装就有的，但需要自己修改好ip、user、password等addcomputernode.conf，中不包含的配置项 ，这里可以先改好，和sh文件放同目录。然后sh脚本会复制过去。一个环境都一样的，只用改一次。
4）neutron.con，这个也是yum安装后有的，也是修改后。同3，一个环境都一样的，只用改一次。
