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:
是这边修改吧？
对的，就是在pd_servers 里面增加一行port: xxxx就行
怎么配置这些参数，有培训的课程么？
启动了两次吧, 先杀掉所有在,重新初始化下
使用tiup cluster temple 导出模板 有配置说明
