社区版本

线下测试环境：

observer 4.3.5.1 最新版

obproxy 4.3.3.0-5 最新版

obbinlog 4.2.3 最新版

另一套4.2.5OB 线下环境环境创建obbinlog正常：

obproxy 4.3.3.0-5

observer 4.2.5.1

obbinlog 4.2.3

obbinlog server服务器信息

cat /etc/issue

Kernel \r on an \m

uname -r

cat /etc/redhat-release

OCP里租户开通binlog超时失败，重复删除binlog集群，新创建也是该错误

登录binlog server 2983端口改binlog实例convert_running: No

数据字典刷新配置已经修改为1h，重试几次还是binlog实例异常

详细binlog_instance和libcdc 日志如下

看着报错 是因为找不到Failed to open index file: ./data/mysql-bin.index, errno: 2(No such file or directory)

另外看你那边用的是 ob435bp1， obbinlog 4.2.3 目前还没有适配ob435bp1，所以这个问题可能是版本不适配引起的。如果想适配 ob435bp1，需要手动安装一下 ob435bp1 的 obcdc。https://www.oceanbase.com/docs/community-oblogproxy-doc-1000000001493746
