本文主要是根据官方文档指导,结合实际主机情况,在Cent OS7上使用TiUP在线部署TiDB。
类型 | 操作系统版本 | 配置 |
---|---|---|
中控机 | Deepin 20.3 | 4核CPU+6G内存+40G硬盘 |
TiDB部署机 | Cent OS 7.3 | 8核CPU+48G内存+100硬盘 |
网络情况 | 中控机与外网相连,中控机与部署机网络互通 |
# 安装TiUP工具
$ curl --proto '=https' --tlsv1.2 -sSf https://tiup-mirrors.pingcap.com/install.sh | sh
# 重新声明全局环境变量
$ source .bash_profile
# 确认Tiup 是否安装
$ which tiup
/root/.tiup/bin/tiup
# 安装TiUP cluster组件
$ tiup cluster
# 查看TiUP cluster版本
$ tiup --binary cluster
/root/.tiup/components/cluster/v1.11.3/tiup-cluster
## 全局变量,ssh端口要填写部署机实际的ssh端口
global:user: "tidb"ssh_port: 2333deploy_dir: "/tidb-deploy"data_dir: "/tidb-data"

附录:官方在线文档中,还部署了TiFlash,但是实际执行总是报错,因此在本配置文件中移除了TiFlash部署。
在中控机执行以下指令:
tidb-test
为集群名
v6.5.0
为要安装的TiDB集群组件版本
--user root
为部署机的ssh账号,需根据实际替换
./topo.yaml
为集群拓扑配置
-p
为执行交互,输入ssh账号密码
$ tiup cluster deploy tidb-test v6.5.0 ./topo.yaml --user root -p
$ tiup cluster start tidb-test
# 查看集群信息,包括集群名、版本、安装用户等
$ tiup cluster list

Total nodes: 8
方式一:使用navicat
按照mysql的连接方式192.168.57.10:4000端口即可
方式二:访问http://192.168.58.10:2379/dashboard
访问监控面板
