首次AWS直接域名托管及Google Zeta域名绑定EC2实例上线流程咨询

Hey there, if you want to host a domain directly on AWS, Amazon Route 53 is your one-stop solution—it handles both domain registration and DNS management seamlessly. Here's how to get started:

• Log into the AWS Console and navigate to the Route 53 service.
• Click "Register Domain" from the dashboard.
• Search for the domain name you want—Route 53 will instantly show if it's available.
• Once you pick an available domain, fill in the required registration details (contact info, privacy protection settings, etc.).
• Complete the payment process, and AWS will register the domain for you. After registration, Route 53 automatically creates a hosted zone for your domain, so you can start configuring DNS records right away.

Let's break this down step by step, assuming you already have your EC2 instance running and full access to your Google Domains account.

准备工作 #

First, make sure you have these ready:

• The public IP address of your EC2 instance (pro tip: use an Elastic IP instead of the default public IP—Elastic IPs stay tied to your instance even after restarts, avoiding DNS disruptions).
• Access to your Google Domains dashboard to modify DNS settings.

Step 1: Create a Hosted Zone in Route 53 #

• Go to the Route 53 Console and click "Create hosted zone".
• Enter your full domain name (e.g., myawesomeblog.com), select "Public hosted zone", then click "Create hosted zone".
• After creation, you'll see 4 Route 53 name servers (e.g., ns-1234.awsdns-12.org). Copy all 4—you'll need these for the next step.

Step 2: Update DNS Servers in Google Domains #

• Log into your Google Domains account, locate your domain, and head to the "DNS" settings page.
• Find the "Name servers" section, switch from "Google Domains name servers" to "Custom name servers".
• Paste the 4 Route 53 name servers you copied earlier, then save the changes. Note: DNS propagation can take 15 minutes to a few hours, so don't panic if it doesn't work immediately.

Step 3: Add DNS Records to Point to Your EC2 Instance #

Back in your Route 53 hosted zone, click "Create record" to add the necessary entries:

Example 1: Point root domain (e.g., myawesomeblog.com) to EC2

• Record name: Leave this blank (it defaults to the root domain).
• Record type: Select A (for IPv4 addresses).
• Value: Paste your EC2 instance's Elastic IP (e.g., 1.2.3.4).
• TTL: Keep the default 300 seconds (or adjust if needed).
• Click "Create records".

Example 2: Point www subdomain (e.g., www.myawesomeblog.com) to EC2

• Record name: Enter www.
• Record type: Select A.
• Value: Same Elastic IP as above (1.2.3.4).
• TTL: 300 seconds.
• Click "Create records".

Example 3: IPv6 Setup (if using IPv6 on EC2)

• Record name: Blank or www.
• Record type: Select AAAA.
• Value: Paste your EC2 instance's IPv6 address.
• TTL: 300 seconds.
• Click "Create records".

Step 4: Configure EC2 Security Group #

Your EC2 instance's security group needs to allow incoming traffic for your service (e.g., HTTP/HTTPS):

• Go to the EC2 Console, select your instance, then click the linked security group under "Security".
• Click "Edit inbound rules".
• Add rules for:
  • Type: HTTP, Port range: 80, Source: 0.0.0.0/0 (restrict to specific IPs for better security if possible).
  • Type: HTTPS, Port range: 443, Source: 0.0.0.0/0 (if you plan to use SSL).
• Save the rules.

Step 5: Test the Setup #

Wait for DNS propagation to finish, then verify:

• Run the command nslookup myawesomeblog.com or dig myawesomeblog.com in your terminal—you should see your EC2 instance's IP in the output.
• Open a browser and enter your domain—you should be able to access the service running on your EC2 instance.
