# tidb4.0 单机部署
## 准备环境
- 参照地址：https://pingcap.com/docs-cn/stable/check-before-deployment/
- 主要关注：防火墙、免密登陆、关闭swap
- 准备环境注意点：
当前主机针对tidb用户免密登陆：
```
ssh-copy-id -i ~/.ssh/id_rsa.pub tidb@本主机
```
## 开始安装
- 参照地址：https://pingcap.com/docs-cn/stable/quick-start-with-tidb/
参照第三个方案：
第三种：使用 TiUP cluster 在单机上模拟生产环境部署步骤
#### 下载并安装 TiUP
```
curl --proto '=https' --tlsv1.2 -sSf https://tiup-mirrors.pingcap.com/install.sh | sh
```
#### 安装 TiUP 的 cluster 组件
```
tiup cluster
```
#### 配置模板10.0.1.1 替换自己的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.

#### 执行集群部署命令
```
