但是很多内网环境不支持外网连接，即使是临时开通部署后，后续运维也可能会遇到报错：
1
failed to start: fetch /timestamp.json from mirror(https://tiup-mirrors.pingcap.com) failed: download from https://tiup-mirrors.pingcap.com/timestamp.json failed: Get “https://tiup-mirrors.pingcap.com/timestamp.json”: dial tcp: lookup tiup-mirrors.pingcap.com on 114.114.114.114:53: read udp 192.168.52.2:44673->114.114.114.114:53: i/o timeout

## 代表为官方镜像源 [root@lucifer ~]# tiup mirror show https://tiup-mirrors.pingcap.com
建议内网环境部署完成后，切换为本地离线镜像源，方便运维。
离线部署
准备 TiUP 离线组件包
首先，找一台可以连接外网的主机，在线安装 TiUP 包管理器工具：
