为什么要修改服务器ip呢？
ip -a 看下
单机环境还是？
单机环境，集群方式启动的
这种方式参考下https://ask.oceanbase.com/t/topic/35604748/6

当时已经看过这解决办法了，但是不适用
1.我部署的是单机版本，没有其他备份服务器
2.目前旧IP已经无法使用，修改旧配置启动时 在SSH Connection阶段就会报错 。
有无其办法可以将旧库内的数据提取出来 ，我就可以重新部署集群了
之前修改的方式是通过什么方式修改的呢？
是通过edit-config方式将ip地址进行修改的嘛。
之前因为没有数据，是直接重新构建集群的。
ob当前不支持直接修改ip地址。
建议：可以试着修改修改服务器ip地址看看呢。
那是否有办法在不启动OB的情况下将数据库已存储数据导出
没办法。
如果是通过edit-config方式修改的ip，环境会被重装。最好的办法就是把之前ip改回来（配置文件也得还原） 然后新建个集群 创建主备租户 让数据同步 以便于再出现类似情况。
当前是生产环境还是测试呢？
