1、下载并安装 TiUP
curl --proto '=https' --tlsv1.2 -sSf https://tiup-mirrors.pingcap.com/install.sh | sh
2、声明全局环境变量
注意看第一步执行完的内容，页面的日志中会打印相关的source相关信息，直接复制执行即可
source ${your_shell_profile}
3、安装 TiUP 的 cluster 组件
tiup cluster
执行如上命令，若机器已经安装 TiUP cluster，需要更新软件版本：
tiup update --self && tiup update cluster
4、修改配置
由于模拟多机部署，需要通过 root 用户调大 sshd 服务的连接数限制：
- 修改 /etc/ssh/sshd_config 将 MaxSessions 调至 20。
- 重启 sshd 服务：
service sshd restart
5、创建并启动集群
- 按下面的配置模板，编辑配置文件，命名为 topo.yaml
- host：设置为本部署主机的 IP
# # 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.
monitored:
node_exporter_port: 9100
blackbox_exporter_port: 9115

tikv:

monitoring_servers:
- host: 192.168.30.43

6、执行集群部署命令
#tiup cluster deploy <cluster-name> <tidb-version> ./topo.yaml --user root -p tiup cluster deploy tidb_v640 v6.4.0 ./topo.yaml --user root -p
- 参数 <cluster-name> 表示设置集群名称
- 参数 <tidb-version> 表示设置集群版本，可以通过 tiup list tidb 命令来查看当前支持部署的 TiDB 版本
注意错误提示：ssh: unable to authenticate, attempted methods [none password], no supported methods remain
[root@HAST04 tidb]# tiup cluster deploy tidb_v640 v6.4.0 ./topo.yaml -i ~/.ssh/ --user root -p tiup is checking updates for component cluster ... Starting component `cluster`: /root/.tiup/components/cluster/v1.11.0/tiup-cluster deploy tidb_v640 v6.4.0 ./topo.yaml -i /root/.ssh/ --user root -p Input SSH password: + Detect CPU Arch Name - Detecting node 192.168.30.43 Arch info ...

问题原因：跟TiDB依赖的SSH秘钥相关
解决方法：所在服务器上生成密钥，再次执行部署命令
[root@master spark]# ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): /root/.ssh/id_rsa already exists. Overwrite (y/n)? y Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. #注意此时可以看到公共密钥的位置存放地址，记住这个，下面会用到 The key fingerprint is: SHA256:7bUrm6Bob+rSnLSXwp+uu8guOkZr+pNCOcp2Zzv6JVc [email protected] The key's randomart image is: +---[RSA 2048]----+ | | | | | | | . | | . SE. . | | = . .. . . | |= o* + +. . . | |=B+oO=Bo ... . | |O***%#O oo. | +----[SHA256]-----+
tiup cluster deploy tidb_v640 v6.4.0 ./topo.yaml --user root i
执行完如上的操作后，若还是继续报错，则继续向下执行：
vim /etc/ssh/sshd_config
[root@localhost tidb]# service sshd restart Redirecting to /bin/systemctl restart sshd.service
此时，继续向下执行，执行后的正确打印信息如下：
[root@HAST04 tidb]# tiup cluster deploy tidb_v640 v6.4.0 ./topo.yaml --user root i tiup is checking updates for component cluster ... Starting component `cluster`: /root/.tiup/components/cluster/v1.11.0/tiup-cluster deploy tidb_v640 v6.4.0 ./topo.yaml --user root i + Detect CPU Arch Name - Detecting node 192.168.30.43 Arch info ... Done + Detect CPU OS Name - Detecting node 192.168.30.43 OS info ...

7、启动集群
[root@HAST04 tidb]# tiup cluster start tidb_v640
8、停止集群
[root@HAST04 tidb]#tiup cluster stop tidb_v640
9、查看集群状态
[root@HAST04 tidb]# tiup cluster display tidb_v640 #打印的集群信息如下 tiup is checking updates for component cluster ... A new version of cluster is available: The latest version: v1.11.1 Local installed version: v1.11.0 Update current component: tiup update cluster Update all components: tiup update --all Starting component `cluster`: /root/.tiup/components/cluster/v1.11.0/tiup-cluster display tidb_v640 Cluster type: tidb Cluster name: tidb_v640 Cluster version: v6.4.0 Deploy user: tidb SSH type: builtin Dashboard URL: http://192.168.30.43:2379/dashboard #tidb的面板 Grafana URL: http://192.168.30.43:3000 #tidb的监控界面 ID Role Host Ports OS/Arch Status Data Dir Deploy Dir -- ---- ---- ----- ------- ------ -------- ---------- 192.168.30.43:3000 grafana 192.168.30.43 3000 linux/x86_64 Up - /tidb-deploy/grafana-3000 192.168.30.43:2379 pd 192.168.30.43 2379/2380 linux/x86_64 Up|L|UI /tidb-data/pd-2379 /tidb-deploy/pd-2379 192.168.30.43:9090 prometheus 192.168.30.43 9090/12020 linux/x86_64 Up /tidb-data/prometheus-9090 /tidb-deploy/prometheus-9090 192.168.30.43:4000 tidb 192.168.30.43 4000/10080 linux/x86_64 Up - /tidb-deploy/tidb-4000 192.168.30.43:9000 tiflash 192.168.30.43 9000/8123/3930/20170/20292/8234 linux/x86_64 N/A /tidb-data/tiflash-9000 /tidb-deploy/tiflash-9000 192.168.30.43:20160 tikv 192.168.30.43 20160/20180 linux/x86_64 Up /tidb-data/tikv-20160 /tidb-deploy/tikv-20160 192.168.30.43:20161 tikv 192.168.30.43 20161/20181 linux/x86_64 Up /tidb-data/tikv-20161 /tidb-deploy/tikv-20161 192.168.30.43:20162 tikv 192.168.30.43 20162/20182 linux/x86_64 Up /tidb-data/tikv-20162 /tidb-deploy/tikv-20162 Total nodes: 8
注意：从如上的信息中可以看出：
- tiflash状态为N/A：如果你不用tiflash的列存储，只是看tikv的事务能力，则可忽略tiflash的状态，若需要HTAP能力，则需要启动Tiflash，，首先查看tiflash的使用Ports端口是否均未被占用，若被占用，则停止掉被占用的进程，重新启动集群。
- tiflash状态为down：则需要等一会，tiflash的启动会相比较慢一些，过一会了再次查看集群状态即可
10、访问集群
- 安装 MySQL 客户端。如果已安装 MySQL 客户端则可跳过这一步骤。
yum -y install mysql
- 访问 TiDB 数据库，密码为空：
mysql -h 192.168.30.43 -P 4000 -u root
[root@HAST04 .ssh]# mysql -h 192.168.30.43 -P 4000 -u root Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 407 Server version: 5.7.25-TiDB-v6.4.0 TiDB Server (Apache License 2.0) Community Edition, MySQL 5.7 compatible Copyright (c) 2021, 2022 StoneAtom Group Holding Limited Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql>
- 访问 TiDB 的 Grafana 监控：
通过 http://192.168.30.43:3000/login 访问集群 Grafana 监控页面，默认用户名和密码均为 admin。
- 访问 TiDB 的 Dashboard：
通过http://192.168.30.43:2379/dashboard/访问集群 TiDB Dashboard 监控页面，默认用户名为 root，密码为空。
- 执行以下命令确认当前已经部署的集群列表：
tiup cluster list
- 执行以下命令查看集群的拓扑结构和状态：
tiup cluster display <cluster-name>
增加Tiflash
tiup ctl:v6.4.0 pd -u http://192.168.30.43:2379 config set enable-placement-rules true
