【 使用环境 】测试环境
【 OB or 其他组件 】OBD
【 使用版本 】OBD2.1.1
【问题描述】obd web命令进行白屏部署。选项如下
1、完全部署。
2、Zone 名称把默认的后面2个删掉了，只留了1个Zone1（OBServer节点）
3、集群模式为最小可用。
【问题现象及影响】
1、在“集群配置”选项时，点“更多配置”，会报错网络异常，您的网络发生异常，无法连接服务器。见附件1.
2、在“预检查”步骤时，出现请求错误，Internal Server Error。
错误截图和obd web打印日志已在附件。

obd web预检查错误时的日志
这个环境之前部署过obd吗？ 另外浏览器打开f12 看看点击更多配置时 发送的请求和响应的数据
是的，之前部署过obd的，然后卸载了重装过。
点击“ 更多参数”时 请求内容如下：

怀疑2个方面：
1、obweb 服务异常 — 》通过kill obd web进程 重启解决
2、obd环境之前没卸载干净 --》 卸载obd 删除~/.obd 重新安装
1、已经重开终端，重新obd web重新开始也一样错误。
2、obd环境，已经通过obd cluster destroy卸载。
也通过rpm -qa|grep ob-deploy和rpm -e --nodeps xxx 卸载了。
并且把.obd删除了rm -rf ~/.obd/*
同时环境变量 ~/.bash_profile/内的已经删除并且重启了终端。
你用的obd 通过在线去拉镜像 还是通过all in one形式安装的
之前是通过all in one安装的，这次是在线安装的。
obd --verison 看一下 目前生效的版本
这些操作都试过了，清理过了
obd --verison版本

点击“更多配置”时日志打印的异常是这样的，你看下根据错误提示能不能有点头绪：
有句TypeError: ‘NoneType’ object is not callable是不是关键问题？

把软件包 all-in-one 都下载下来 ，把之前的安装包和目录都手动删除掉。（rpm -e 和 /bin/rm -rf ~/.obd, 退出所有终端，看看 .bash_profile 里有残留 环境变量 export 设置么)
另外看看 python 版本。
重新安装试试，参考： OB 社区版 4.1 和 OCP express 笔记本电脑部署体验 (qq.com) ，每一步命令操作，截大图，所有信息 都提供（不要部分信息和图）。如果报错，有 log 就提供log 。
信息全了，有问题大家也能帮忙看。
官网下载的 oceanbase-all-in-one 里 OBD 版本是 2.1.0 。 先全部下载下来试试。
@谐云 已经安装了 OBD 2.1.0 的，好像没有办法通过 obd update 升级到 2.1.1 .

问题已解决。原因是使用教程文章《 通过 OBD 白屏部署 OceanBase 集群》的“在线部署”方案时，可能下载的组件缺失或有问题。
教程地址：
https://www.oceanbase.com/docs/common-oceanbase-database-cn-10000000001697442
解决方案是：
使用这教程里的“离线部署”方案，把 all-in-one 安装包拷到目标机器里再安装。
建议：
在线安装部分教程可能存在问题，请检查核实。
如果是在线包缺失 可以在~/.obd/repository/ 目录下删除组件对应的包 下次会自动下载。目前下载检查逻辑只判断了 有对应的包 就不会下载了。没有才下载
~/.obd/删除过几次了，然后按文章教程的重复在线安装数次，依然提示这个。你们重复下这些步骤看能否重现？
