Orchestrator client 用法

查询当前有哪些集群

orchestrator-client -c clusters
git.sqlpy.com:4406

查询指定集群的拓扑

orchestrator-client -c topology -i git.sqlpy.com:4406
git.sqlpy.com:4406     [0s,ok,8.0.33,rw,ROW,>>,GTID,semi:master]
+ git.sqlpy.com:4407   [0s,ok,8.0.33,ro,ROW,>>,GTID,semi:replica]
  + git.sqlpy.com:4408 [0s,ok,8.0.33,ro,ROW,>>,GTID,semi:replica]

调整复制的层级结构

orchestrator-client -c relocate -i git.sqlpy.com:4408 -d git.sqlpy.com:4406
git.sqlpy.com:4408<git.sqlpy.com:4406

orchestrator-client -c topology -i git.sqlpy.com:4406
git.sqlpy.com:4406   [0s,ok,8.0.33,rw,ROW,>>,GTID,semi:master]
+ git.sqlpy.com:4407 [0s,ok,8.0.33,ro,ROW,>>,GTID,semi:replica]
+ git.sqlpy.com:4408 [0s,ok,8.0.33,ro,ROW,>>,GTID,semi:replica]

手工切换

orchestrator-client -c  graceful-master-takeover -i git.sqlpy.com:4407 -d git.sqlpy.com:4407

orchestrator-client -c topology -i git.sqlpy.com:4406
git.sqlpy.com:4407   [0s,ok,8.0.33,rw,ROW,>>,GTID]
- git.sqlpy.com:4406 [null,nonreplicating,8.0.33,ro,ROW,>>,GTID,semi:master,downtimed]
+ git.sqlpy.com:4408 [0s,ok,8.0.33,ro,ROW,>>,GTID,semi:replica]
