数据库克隆（克隆的主机只需要安装软件不需要安装实例）

主库为99的odsv实例，克隆的为26的odsv实例（克隆的名字可以和主库一样也可以不一样）

#查看归档

#创建一个screen进程（这个进程即使远程断开也会继续执行命令，没有这个进程yum安装）在screen进程中执行克隆命令
新建\：screen -S lkl -L
script /dev/null            #Cannot open your terminal '/dev/pts/1' - please check.  报错解决方案
查看screen：screen -ls
进入screen: screen -r lkl
