0，集群节点以及脚色

TiDB的集群有多种架构，除了用于测试体验的“摆设本地测试集群”和“在单机上模仿摆设生产情况集群”之外，参考官方文档，顺应于天生情况的集群，基于最小拓扑架构集群的TIDB安装，呆板的IP地点以及脚色分配如下：
1，节点脚色如下，1个Monitor节点+2个TIDB节点+3个PD节点+3个TiKV节点，一共9个节点
实例个数物理机设置IP设置TiDB216 VCore 32 GiB
100 GiB 用于存储192.168.152.132
192.168.152.133默认端口
全局目次设置PD34 VCore 8 GiB
100 GiB 用于存储192.168.152.126
192.168.152.127
192.168.152.128默认端口
全局目次设置TiKV316 VCore 32 GiB
2 TiB (NVMe SSD) 用于存储192.168.152.129
192.168.152.130
192.168.152.131默认端口
全局目次设置Monitoring & Grafana14 VCore 8 GiB
500 GiB (SSD) 用于存储192.168.152.134默认端口
全局目次设置2，本文情况涉及到的主机与IP如下：
192.168.152.126 ubuntu16
192.168.152.127 ubuntu17
192.168.152.128 ubuntu18
192.168.152.129 ubuntu19
192.168.152.130 ubuntu20
192.168.152.131 ubuntu21
192.168.152.132 ubuntu22
192.168.152.133 ubuntu23
192.168.152.134 ubuntu24
1，SSH互信设置

1，恣意两台之间要设置为SSH互信，过程略，由于这里涉及较多的呆板，恣意两台之间都要相互信托，传统手动设置起来非法贫苦，这里就八仙过海各显神通，可以接种AI天生各种骚脚原来实现，这里不是本文的重点2，修改 /etc/ssh/sshd_config 将 MaxSessions 调至 20大概更高，然后重启sshd服务。

root@ubuntu15:~# vi /etc/ssh/sshd_config
root@ubuntu15:~#
root@ubuntu15:~# service sshd restart

复制代码

2，TiUP 安装

2.1 TiUP是做什么的？
一句话：TiUP是TiBD的主动化安装下令。
TiUP 对于 TiDB 生态，就犹如 yum之与 CentOS/RHEL ，或 apt 之与 Ubuntu 利用体系。它们都扮演着包管理器（Package Manager）的核心脚色，办理了软件摆设和管理的三个关键标题：下载、安装、依靠管理。
2.2 TiUP安装位置？
TiUP可以安装在集群呆板中的恣意一台上，这里安装在Monitoring Server上，也即ubuntu24上，从ubuntu24上发起集群的创建，以下全部的利用都在ubuntu24上实验
TiUP安装下令：curl --proto '=https' --tlsv1.2 -sSf https://tiup-mirrors.pingcap.com/install.sh | sh

root@ubuntu24:~# curl --proto '=https' --tlsv1.2 -sSf https://tiup-mirrors.pingcap.com/install.sh | sh

root@ubuntu24:~# source /root/.bashrc

3，安装 TiUP Cluster

TiUP Cluster是什么？专门用于生产情况 TiDB 集群的摆设和运维管理，TiUP Cluster 可以以为是 TiUP 工具包中的一个核心子集（或子下令）。
安装下令：tiup cluster

root@ubuntu24:~# tiup cluster
Checking updates for component cluster... Timedout (after 2s)
The component `cluster` version is not installed; downloading from repository.
download https://tiup-mirrors.pingcap.com/cluster-v1.16.5-linux-amd64.tar.gz 9.76 MiB / 9.76 MiB 100.00% 16.89 MiB/s

root@ubuntu24:~#

4，编写集群设置文件

1，集群设置文件的作用？
引导集群的搭建以及脚色分配，集群设置文件中指定了集群中的脚色对应的主机IP，相当于提前指定好集群中每个节点的脚色，目标是创建集群是引导文件，而不是集群运行的引导文件。
2，集群设置文件的位置？
上面提到“以下全部的利用都在ubuntu24上实验”，这里将设置文件放在ubuntu24下的/TiDB/topo.ymal（topo寄义为拓扑），如下

# # 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"
pd_servers:
- host: 192.168.152.126
- host: 192.168.152.127
- host: 192.168.152.128
tidb_servers:
- host: 192.168.152.132
- host: 192.168.152.133
tikv_servers:
- host: 192.168.152.129
- host: 192.168.152.130
- host: 192.168.152.131
monitoring_servers:
- host: 192.168.152.134
grafana_servers:
- host: 192.168.152.134
alertmanager_servers:
- host: 192.168.152.134

复制代码

5，TiDB集群安装

安装版本检察：tiup list tidb检察可供安装的TiDB集群版本，有上百个可用安装的版本可选。

这安装最新的稳固版v8.5.6，集群定名为TiDBCluster ，下令如下
tiup cluster deploy TiDBCluster v8.5.6 /TiDB/topo.yaml --user root -p，安装过程会主动再各个节点上创建对应的目次，然后下载对应的安装包，末了主动安装

root@ubuntu24:~# tiup cluster deploy TiDBCluster v8.5.6 /TiDB/topo.yaml --user root -p

Cluster `TiDBCluster` deployed successfully, you can start it with command: `tiup cluster start TiDBCluster --init`

复制代码

6，启动集群

根据上述提示：you can start it with command: `tiup cluster start TiDBCluster --init`，笔者这里使用tiup cluster start TiDBCluster，没有加--init，也可以正常启动。
启动集群的本质就是：将集群中安装的TIDB组件注意启动起来

7，客户端毗连

TIDB兼容MySQL客户端协议，就把他当MySQL用好了，默认暗码为空：mysql -h 192.168.152.132 -P 4000 -u root，修改root暗码：ALTER USER 'root'@'%' IDENTIFIED BY 'root';

8，集群检察

实验以下下令确认当前已经摆设的集群列表：tiup cluster list

root@ubuntu15:~# tiup cluster list
Name User Version Path PrivateKey
---- ---- ------- ---- ----------
TiDBCluster tidb v8.5.6 /root/.tiup/storage/cluster/clusters/TiDBCluster /root/.tiup/storage/cluster/clusters/TiDBCluster/ssh/id_rsa
root@ubuntu15:~#

复制代码

实验以下下令检察集群的拓扑布局和状态：tiup cluster display TiDBCluster

9，集群监控

配景

注意上面的输出

Dashboard URL: http://192.168.152.125:2379/dashboard
Dashboard URLs: http://192.168.152.125:2379/dashboard
Grafana URL: http://192.168.152.125:3000

复制代码

Monitor Server：访问 Grafana 监控

页面：http://192.168.152.134:3000，默认用户名和暗码均为 admin。PD Server：访问集群 TiDB Dashboard 监控

页面：http://192.168.152.126:2379/dashboard，默认用户名为 root，暗码为空。

对于Monitor Server的prometheus和 Grafana监控，已经预定了多个garfana的dashboard，以及altermanager告警规则，这里随意截几个图，不逐一截图，非常本心，从安装到监控，再到告警，可谓是一站式服务（白嫖）。

访问集群 TiDB Dashboard 监控页面，是对于PD监控的控制台页面

10，设置systemctl服务

以上通过下令启动了TIDB集群中各个节点上的组件，如果要设置为systemctl主动启动，必要实验，tiup cluster enable TiDBCluster
