Redhat7.3环境下最小拓扑架构TIDB安装（附图）
之前讲过单机版TIDB安装，因为资源有限将TiDB，PD，TiKV安装在了同一台服务器上，详见：Redhat7.3环境下单机版TIDB安装（附图）
本篇介绍开发及测试环境最小拓扑架构安装。参考官方文档：https://docs.pingcap.com/zh/tidb/stable/hardware-and-software-requirements
| 组件 | CPU | 内存 | 本地存储 | 网络 | 实例数量(最低要求) |
|---|---|---|---|---|---|
| TiDB | 8 核+ | 16 GB+ | 无特殊要求 | 千兆网卡 | 1（可与 PD 同机器） |
| PD | 4 核+ | 8 GB+ | SAS, 200 GB+ | 千兆网卡 | 1（可与 TiDB 同机器） |
| TiKV | 8 核+ | 32 GB+ | SSD, 200 GB+ | 千兆网卡 | 3 |
从上面表格可以看出，开发和测试环境仅需要4台服务器即可。我们将TiDB和PD部署在同一台服务器，另外再需要3台TiKV服务器。
最小拓扑安装和单机版TiDB安装唯一的区别是topology.yaml文件配置不一样，其它安装环节一模一样，真的一模一样。所以安装的具体流程参考：Redhat7.3环境下单机版TIDB安装（附图）
最小拓扑安装topology.yaml文件配置如下：
# # 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: 172.16.43.110 tidb_servers: - host: 172.16.43.110 tikv_servers: - host: 172.16.43.107 - host: 172.16.43.108 - host: 172.16.43.109 monitoring_servers: - host: 172.16.43.110 grafana_servers: - host: 172.16.43.110 alertmanager_servers: - host: 172.16.43.110
