1. gitlab 使用容器方式啟動的，分別在 192.168.1.247 ， 192.168.1.248 兩個節點部署；
2. 兩個節點共同掛載nfs存儲到本地/nfs-storage；
```bash
192.168.1.249:/storage /nfs-storage nfs rsize=8192,wsize=8192,timeo=14,intr
```
3. gitlab 容器將數據目錄映射在nfs-掛載目錄，實現兩個節點故障切換后數據一致\(轉到Gitlab/README.md\)
4. 使用Keepalived 地址漂移功能進行故障切換\(轉到Gitlab\_高可用-Keepalived\)
5. 使用compose啟動后可能會有無法發送郵件的問題，安裝以下方法修改重啟即可；
