DNS Configurations
Server A -> sub domain -> Server B
目前Domain是指到Server A, 但是想要開一個subdomain指到Server B
- 取得Server B的IP
- 在Server B中建一個sub domain
- 在Server A中建一個sub domain
- 修改#3 sub domain的A record, 指到#1的IP
GSuit -> Godaddy
- 如果網址是在gsuite買的，在Gsuite控制台會有地方查詢到網域相關的資料，並且有登入godaddy domain manager的帳密和網址
- 在Godaddy另外開一個帳號建立網站
- #2完成後，在網域的地方可以查到server的IP
- 在#1的domain manager中，把A record指到#3的IP
