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。 ```shell [admin@ob61 ~]$ rm -rf /home/admin/oceanbase/ ``` 2. 使用如下命令查看 OBServer 进程。 ```shell [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。 ```shell [root@ob61 ~]# pkill -9 observer ``` 4. 再次使用如下命令查看 OBServer 进程。 ```shell [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。 ```shell [admin@ob58 ~]$ tar --exclude='log/*' -cpzvf

[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。 ```shell [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。 ```shell [admin@ob61 ~]$ tar zxvf oceanbase.tar.gz -C / home/admin/oceanbase/ home/admin/oceanbase/admin/ home/admin/oceanbase/admin/__dbms_upgrade.sql

进程，需要注意下面的 IP 地址和 Zone 名称需要根据当前节点的实际值调整一下。 ```shell [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

#### 说明 - 上面的恢复步骤仅适用于 `/home/admin/oceanbase/` 目录被删除的情况，如果 Clog 或者 Data 数据文件同时也被删除，该方法暂时不适用。 - 如果有多个 OBServer 节点上的 `/home/admin/oceanbase/` 目录被删除，只需要在每一个发生问题的节点上执行上面的恢复步骤即可。 ## 适用版本 OceanBase 数据库
