工具介绍:

创建虚拟机会使用多线程队列的方式去控制同时创建的虚拟机数量


如果在创建的虚拟机比较多,会2次创建。第一次会在各个宿主机上创建一台,其余的会再第一次创建成功后创建。


因为第一次创建需要传输镜像会比较慢,在宿主机上已经有对应的镜像后,再次创建相同镜像的虚拟机,不再需要传输相应的镜像(所有相同镜像的虚拟机共用同一个后端镜像,openstack对镜像管理使用copy on write技术)

查询和更改主要都是通过查询数据库实现。


其它功能自测。



使用帮助:

python openstack_manager.py --help

创建虚拟机:

python openstack_manager.py -c -f vmhost -t nslm

-c, 指定是要进行创建虚拟机 , -f  指定要创建的虚拟机列表文件 , -t 指定要给那个项目创建虚拟机

删除虚拟机:

python openstack_manager.py -d ip1 ip2

-d  指定要删除的ip ,可以跟多个

查看某个虚拟机信息

python openstack_manager.py -i ip1 ip2

-i 指定ip,后面可以跟上多个值

查看宿主机下的虚拟机信息

python openstack_manager.py -n node1 node2

-n 指定node,可以跟上多个值

更改虚拟机配置:

python openstack_manager.py -u ip -F flavor

-u指定某个ip, -F 指定某个配置

批量ping:

python openstack_manager.py -p -f vmhost

-p指定进行批量ping,-f指定文件

从文件中获取创建虚拟机的命令

(创建过程中某个虚拟机出错,可以进行查看创建虚拟机命令进行手动创建)

python openstack_manager.py -g -f vmhost -t

-g指定要进行获取命令,-f指定文件,-t指定项目


-f 指定文件的文件格式:

批量ping是检查ip虚拟机是否存在,指定的文件也是参照此格式

nodename instance_ip flavor

一行一个虚拟机


其它使用信息:

脚本中的flavor对应的flavor id,项目帐号密码和镜像ID,数据库帐号等替换成自己生产环境中的信息
