启动两次?4000端口被占用了?

4000端口没被占用,我用的下面的命令启动的:
tiup cluster start mytidb --init
然后就一直卡死在启动4000端口那步

启动两次可能是retry

[root@localhost tidb]# tiup cluster check ./topo.yaml --apply --user root -p
tiup is checking updates for component cluster …
Starting component cluster: /root/.tiup/components/cluster/v1.9.5/tiup-cluster /root/.tiup/components/cluster/v1.9.5/tiup-cluster check ./topo.yaml --apply --user root -p

Error: Deploy port conflicts to an existing cluster (spec.deploy.port_conflict)

The port you specified in the topology file is:
Port: 2379
Component: pd 127.0.0.1

It conflicts to a port in the existing cluster:
Existing Cluster Name: mytidb
Existing Port: 2379
Existing Component: pd 127.0.0.1

Please change to use another port or another host.

2379端口如何修改?

这个是PD的端口,你在拓扑文件中把PD的端口单独设置成其他端口就行

pd_servers:

  • host: 127.0.0.1
    port: xxxx

是这边修改吧?

对的,就是在pd_servers 里面增加一行port: xxxx就行
