Google Cloud DNS使用記錄


DNS是網際網路服務上不可或缺的一項服務,Google Cloud Platform上當壖也不能缺少這個服務... 果然在今年度問世了... 這邊介紹整個操作與設定的過程...

Zone的管理

Record管理

檢視DNS Zone下的記錄(record)

插曲 - 安裝textmate並且設定至路徑




Mac的用戶,可以下載TextMate:http://macromates.com/,並安裝至Application folder,然後透過下面指令將mate link到/usr/bin/mate

$ sudo ln -s /Applications/TextMate.app/Contents/SharedSupport/Support/bin/mate /usr/bin/mate

其中,mate需要安裝1.5.11版本,才可以在路徑中找到mate德執行檔... 安裝完之後,再執行一次上面指令,就可以正常編輯DNS記錄檔案...



編輯好後,儲存並關閉,則console會跳轉到執行結束畫面,執行結束會列表目前的record設定狀況,因此在這邊就可以看到剛剛所增加的設定值。

測試記錄是否寫入


要確認record是否正常寫入,可以透過gcloud dns records list的方式列表...

peixindeMacBook-Pro in ~
○ → gcloud dns records --zone="gcp-arecord-us" list
[
   {
       "kind": "dns#resourceRecordSet",
       "name": "gcp.arecord.us.",
       "rrdatas": [
           "ns-cloud-d1.googledomains.com.",
           "ns-cloud-d2.googledomains.com.",
           "ns-cloud-d3.googledomains.com.",
           "ns-cloud-d4.googledomains.com."
       ],
       "ttl": 21600,
       "type": "NS"
   },
   {
       "kind": "dns#resourceRecordSet",
       "name": "gcp.arecord.us.",
       "rrdatas": [
           "ns-cloud-d1.googledomains.com. dns-admin.google.com. 1 21600 3600 1209600 300"
       ],
       "ttl": 21600,
       "type": "SOA"
   },
   {
       "kind": "dns#resourceRecordSet",
       "name": "www.gcp.arecord.us.",
       "rrdatas": [
           "192.168.2.10"
       ],
       "ttl": 86400,
       "type": "A"
   }
]

檢視DNS是否設定完成


確認好令表正確之後,接下來可以確認一下記錄是否已經生效...

peixindeMacBook-Pro in ~
Address: 216.239.32.109#53

Address: 192.168.2.10

後續


到這邊為止,記錄雖然已經生效,但是還無法讓網際網路上的大眾找到您的記錄,所剩的臨門一腳是~將DNS記錄指向到適當的DNS server位置,如果需要找DNS server位置,可以透過下面指令:

peixindeMacBook-Pro in ~
○ → gcloud dns managed-zone get gcp-arecord-us
{
   "creationTime": "2014-04-24T11:32:03.853Z",
   "description": "A zone",
   "dnsName": "gcp.arecord.us.",
   "id": "1595320562141013743",
   "kind": "dns#managedZone",
   "name": "gcp-arecord-us",
   "nameServers": [
   ]
}

其中nameServers的位置,設定到網域提供商所指定的DNS name server位置即可,而如果您設定的是subdomain,則透過指定NS record即可完成設定,下面是godaddy subdomain的記錄設定範例:


設定完成後,等待一段時間,重新確認DNS記錄:

○ → nslookup www.gcp.arecord.us
Server: 168.95.1.1
Address: 168.95.1.1#53

Non-authoritative answer:
