使用binlog无法同步增量数据

[普罗米修斯]

【TiDB 版本】v5.2.4 使用tiup安装部署

【出现的问题】在上游TiDB数据库内写入测试数据，下游mysql没有自动同步，pump和drainer服务均正常，查看drainer.log，发现[2022/05/11 14:40:51.806 +08:00] [ERROR] [pump.go:140] [“pump create pull binlogs client failed”] [id=DC02:8250] [error=“rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial tcp 127.0.0.1:8250: connect: connection refused"”] [errorVerbose=“rpc error: code = Unavailable desc = connection error: desc = "transport: Error while dialing dial tcp 127.0.0.1:8250: connect: connection refused"

TiDB数据库中有

，怎么删除掉这个paused节点。

[Meditator (Wendywong020)]

1） 看看端口不是被占用？
2）4.x 开始不再支持pump和rainer，特别最新版本 ，不确定是否有兼容的问题
3） 有同步的需求后面还是用ticdc
