CentOS 7部署TIDB单机：
curl --proto '=https' --tlsv1.2 -sSf https://tiup-mirrors.pingcap.com/install.sh | sh
source /root/.bash_profile
vi topo.yaml （将10.0.1.1改为实际ip，单ip为单机，多ip即为集群）
# Global variables are applied to all deployments and used as the default value of
# the deployments if a specific deployment value is missing.
global: user: "tidb" ssh_port: 22 deploy_dir: "/tidb-deploy" data_dir: "/tidb-data"
# Monitored variables are applied to all the machines.

tiup cluster deploy ming v7.0.0 ./topo.yaml --user root -p （5.7.25-TiDB-v7.0.0）
输入root密码 输入y（继续）
tiup cluster start ming --init
会给出新的tidb root密码
tiup cluster list
tiup cluster display ming
mysql -h 10.0.1.1 -P 4000 -u root -p'xxxxxxx' （10.0.1.1改为实际ip）
修改tidb的root密码
use mysql; update user set authentication_string=password('xxxxxx') where user='root'; flush privileges;
grafana访问 http://10.0.1.1:3000 初始用户名密码都是admin （10.0.1.1改为实际ip）
tidb dashboard访问 http://10.0.1.1:2379/dashboard 用户名root 密码是上步tidb的密码
