【 TiDB 使用环境】生产环境
【 TiDB 版本】6.1.0
【复现路径】
1、通过tiup搭建的集群，pump一共三个节点，分别分布在不同的服务器上，
| 组件名称 | tidb集群关联IP | 服务器上另外一个网卡的IP |
|---|---|---|
| pump | 172.16.2.119 | 192.168.20.236 |
| 172.16.2.120 | 192.168.20.237 | |
| 172.16.2.35 | 192.168.20.55 | |
| tiup | 172.16.2.105 | 192.168.20.235 |
| 如下图： | ||
|  | |
| 2、集群打开binlog，并扩展安装drainer连接下游mysql用作binlog的实时同步，扩展脚本如下： | ||
| drainer_servers: |
- host: 172.16.2.35
port: 8249
data_dir: “/home/data-tidb/tidb-data/drainer-8249”
commit_ts: -1
deploy_dir: “/home/data-tidb/tidb-deploy/drainer-8249”
config:
syncer.db-type: “mysql”
syncer.to.host: “172.1.1.13”
syncer.to.user: “xxxx”
syncer.to.password: “xxxxx”
syncer.to.port: 4000
扩展后查看集群也是能正常运行的
【遇到的问题：问题现象及影响】
drainer组件没有同步，日志报错：

这里drainer居然识别不到已经搭建好了的pump，而是去控制机上通过另外一块网卡找pump
