failed: time out`。

## 问题风险 单机版 OBServer 部署失败。 ## 问题原因 单机版 OBServer 默认使用 SSH:22 端口来连接远程 OBServer 服务器，但是有些地方出于安全考虑会将 22 端口替换别的端口，所以导致 SSH 连接不上出现上述问题。 ## 解决方案 采取 YAML 配置文件的方式来部署（最快捷的方式是从已经部署好的单机版 OBServer 环境中拷贝一份 YAML 文件然后修改相关的配置信息）。如果没有可用的 YAML 文件的话，可以直接拷贝下面配置文件模版并修改相关参数来部署单机版 OBServer。 ```shell [root@observer ~]# vi mytest.yaml # 文件名字和 cluster_name 保持一致，实际应用中 yaml 文件里的 --注释需要去掉，文件中加粗部分需要根据实际情况更改 user: username: root password: xxxx port: 29022 # 更改成实际的 SSH 端口 oceanbase-standalone: # 这些可以根据实际安装包的信息来查看 obd mirror list local version: 4.3.5.3 release: 103000112025071821.el7 servers: - xx.xx.xx.xx global:
