部署集群

export TIUP_MIRRORS=/root/tidb-server --tidb安装包解压路径
tiup cluster deploy tidb-test v4.0.1 topology.yaml --user tidb [-p] [-i /home/root/.ssh/gcp_rsa] --没有配置免密码，需要两个参数其中一个。tidb-test 集群名，v4.0.1 版本 tidb 系统用户，没有建，在执行这段命令，会自动创建
tiup cluster start tidb-test --启动集群
看到如下信息就表示成功
Deployed cluster tidb-test successfully
