如果误删了整个 /home/admin/oceanbase/ 目录，该如何恢复

本文主要介绍了如果用户误删了 OceanBase 集群中某个 OBServer 节点或者多个 OBServer 节点上的整个 /home/admin/oceanbase/ 目录，这种情况下该如何进行 OceanBase 集群的恢复。

恢复误删了整个 /home/admin/oceanbase/ 目录的步骤

1. 模拟用户误删了整个 /home/admin/oceanbase/ 目录。

    [admin@ob61 ~]$ rm -rf /home/admin/oceanbase/
   

2. 使用如下命令查看 OBServer 进程。

    [root@ob61 ~]# ps -ef | grep observer
    admin     194176       1 81 Jul05 ?        1-21:44:11 /home/admin/oceanbase/bin/observer
    root      886246  883843  0 18:26 pts/0    00:00:00 grep observer
   

3. 将该问题节点上的 OBServer 进程 kill 掉。

    [root@ob61 ~]# pkill -9 observer
   

4. 再次使用如下命令查看 OBServer 进程。

    [root@ob61 ~]# ps -ef | grep observer
    root      886273  883843  0 18:27 pts/0    00:00:00 grep observer
   

5. 在剩余的某个正常的 OBServer 服务器上，将 /home/admin/oceanbase/ 目录整体打包压缩拷贝到上面发生问题的节点上。

    [admin@ob58 ~]$ tar --exclude='log/*' -cpzvf oceanbase.tar.gz /home/admin/oceanbase

6. 查看指定文件大小使用如下命令。

    [admin@ob58 ~]$ du -sh oceanbase.tar.gz
    253M    oceanbase.tar.gz
   

7. 将压缩文件拷贝至发生问题的 OBServer 节点。

    [admin@ob58 ~]$ scp oceanbase.tar.gz admin@192.xxx.xxx.61:~
   

8. 在发生问题的 OBServer 节点上，解压上面拷贝过来的压缩文件。

    [admin@ob61 ~]$ tar zxvf oceanbase.tar.gz -C /

    [admin@ob61 ~]$ cd /home/admin/oceanbase ; ./bin/observer -I 192.xxx.xxx.61 -z zone3 -o "rootservice_list=192.xxx.xxx.59:2882:2881;192.xxx.xxx.58:2882:2881;192.xxx.xxx.61:2882:2881"
    ./bin/observer -I 192.xxx.xxx.61 -z zone3 -o rootservice_list=192.xxx.xxx.59:2882:2881;192.xxx.xxx.58:2882:2881;192.xxx.xxx.61:2882:2881
