【python】openstack管理小工具（增删查改，批量ping）

网络浪子

　　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
