How to distinguish multiple domain names from nginx

Multiple domain names can be distinguished by configuring nginx server block: Specify a unique server_name directive for each domain name. Repeat the above steps to create multiple server blocks. If the requested domain name does not match any server block, nginx will use the default server block for processing.

How to distinguish multiple domain names using nginx

In nginx, you can configure server blocks to serve different domain names. The server block specifies how requests for a specific domain name should be handled.

Configure server blocks

To configure server blocks for a specific domain name, add the following code block in the nginx configuration file:

 <code>server { listen 80; server_name example.com; # 针对example.com 请求的配置}</code>

In this example, the server block will listen for requests on port 80 and serve the domain name example.com.

Create server blocks for different domain names

To create server blocks for multiple domain names, repeat the steps above to specify a unique server_name directive for each domain name. For example:

 <code># example.com server { listen 80; server_name example.com; # 针对example.com 请求的配置} # otherdomain.com server { listen 80; server_name otherdomain.com; # 针对otherdomain.com 请求的配置}</code>

Default server block

If the requested domain name does not match any server block, nginx will use the default server block for processing. The default server block is usually defined at the end of the nginx configuration file.

 <code>server { listen 80 default_server; server_name _; # 针对所有其他域名的请求的配置}</code>

Test configuration

Reload nginx configuration to apply changes:

 <code>nginx -s reload</code>

To test the configuration, use the curl command to send a request to a different domain name. For example:

 <code>curl http://example.com curl http://otherdomain.com</code>

If configured correctly, you will see the corresponding content for each domain name.
