TiDB开启bilog

1.新建文件 scale-out.yaml

pump_servers:
  - host: 192.168.10.225
  - host: 192.168.10.226
  - host: 192.168.10.227
  
drainer_servers:
  - host: 192.168.10.228
  
    config:
      syncer.db-type: "mysql"
      syncer.to.host: "192.168.10.228"
      syncer.to.password: "xxx"

2.扩容安装pump_servers\drainer_servers

3.在线编辑配置

tiup cluster edit-config tidb-poly
在global下新增

global:
  user: root
  ssh_port: 22
  ssh_type: builtin
  deploy_dir: /tidb-deploy
  data_dir: /tidb-data
  os: linux
server_config:
  tidb:
    binlog:
      enable: true
      ignore-error: true

4.重启reload

tiup cluster reload tidb-poly 

5.验证sql

show variables like "log_bin";

show pump status;

show drainer status;
