扩容操作：
1.查看当前集群相关信息：
[tidb@node201 ~]$ tiup cluster display tidb-test

1.1新安装一台主机，IP：172.16.1.204

2.编辑扩容文件注意缩进格式：
vim scale-out-tikv.yaml
添加以下内容，其中，加入tikv节点IP地址为：172.16.1.204，端口号：20160

tikv_servers:
- host: 172.16.1.204
ssh_port: 22
status_port: 20180
deploy_dir: /tidb-deploy/tikv-20160
data_dir: /tidb-data/tikv-20160
log_dir: /tidb-deploy/tikv-20160/log

3.执行以下命令，进行扩容操作：
tiup cluster scale-out tidb-test scale-out-tikv.yaml -uroot -p

[tidb@node201 ~]$ tiup cluster scale-out tidb-test scale-out-tikv.yaml -uroot -p
tiup is checking updates for component cluster …
A new version of cluster is available:

你可以都放一个帖子里，分享学习测试笔记，代码可以用代码块包起来，这样比较好看，类似：
