在这个练习里，我们将集群名由tidb-test 改为tidb-prod，之后改回tidb-test。

1. 使用tiup进行集群名修改，如下所示:

[root@tidb1 ~]# tiup cluster rename tidb-test tidb-prodStarting component `cluster`: /root/.tiup/components/cluster/v1.6.0/tiup-cluster rename tidb-test tidb-prodWill rename the cluster name from tidb-test to tidb-prod.Do you confirm this action? [y/N]:(default=N) y        #输入y继续更改集群名称tidb-test为tidb-prodRename cluster `tidb-test` -> `tidb-prod` successfullyWill reload the cluster tidb-prod with restart policy is true, nodes: , roles: grafana,prometheus.Do you want to continue? [y/N]:(default=N) y          #输入y继续，roles重新加载+ [ Serial ] - SSHKeySet: privateKey=/root/.tiup/storage/cluster/clusters/tidb-prod/ssh/id_rsa, publicKey=/root/.tiup/storage/cluster/clusters/tidb-prod/ssh/id_rsa.pub+ [Parallel] - UserSSH: user=tidb, host=192.168.80.139+ [Parallel] - UserSSH: user=tidb, host=192.168.80.140+ [Parallel] - UserSSH: user=tidb, host=192.168.80.136+ [Parallel] - UserSSH: user=tidb, host=192.168.80.137+ [Parallel] - UserSSH: user=tidb, host=192.168.80.135+ [Parallel] - UserSSH: user=tidb, host=192.168.80.135+ [Parallel] - UserSSH: user=tidb, host=192.168.80.135+ [Parallel] - UserSSH: user=tidb, host=192.168.80.141+ [Parallel] - UserSSH: user=tidb, host=192.168.80.138+ [Parallel] - UserSSH: user=tidb, host=192.168.80.135+ [ Serial ] - UpdateTopology: cluster=tidb-prod+ Refresh instance configs  - Regenerate config pd -> 192.168.80.135:2379 ...

2. 查看集群状态，发现集群名已经改为tidb-prod, 如下:
