3、openstack高可用实现
#==============================================================
1 openstack 虚拟机跨机迁移
#迁移实例，cp镜像到其他node时，用户为nova #nova用户改为可登录shell类型 #各node节点更改nova用户shell类型 # usermod -s /bin/bash nova #设置nova用户密码 # echo nova | passwd --stdin nova #切换至nova用户生成秘钥，相互cp至其他node # su - nova $ ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa $ ssh-copy-id nova@10.0.0.47 #管理员->实例->迁移实例->确认 调整大小/迁移 #=================================================================================== #实例类型动态调整 #项目->计算->实例->对应实例->调整实例大小->新的实例类型：选设定的实例类型 调整大小 确认 调整大小/迁移
