How to use Nginx and PHP to achieve multi-domain name resolution and coexistence of static and pseudo-static pages?

Use Nginx and PHP to cleverly implement multi-domain name resolution and static and pseudo-static page coexistence

In the website architecture of Nginx and PHP, multiple domain name resolutions are often required to be processed at the same time and support access to static pages and pseudo-static pages. This article will introduce how to configure Nginx so that two different domain names point to the same directory and achieve static and pseudo-static access effects respectively.

Suppose we have two domain names: www.example.com and m.example.com , both pointing to the same directory. The requirements are as follows:

• When visiting www.example.com , directly access the static page, such as www.example.com/about.html .
• When accessing m.example.com , a pseudo-static effect is achieved. For example, m.example.com/about.html actually accesses m.example.com/index.php?page=about .

Implementation method:

For www.example.com , since it accesses static pages, there is no need for special configuration, just make sure that the .html file exists in the target directory.

For m.example.com , we need to add pseudo-static rules in Nginx and rewrite the request for .html suffix to the corresponding PHP file. The following is an example of Nginx configuration:

 server {
    listen 80;
    server_name m.example.com;
    root /path/to/your/website; # Replace /path/to/your/website with your website root directory location ~* \.html$ {
        rewrite ^/(.*)\.html$ /index.php?page=$1 last;
    }

    # ... other configurations ...
    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.4-fpm.sock; # Replace with your php-fpm socket path}
}

In this configuration, location ~* \.html$ matches all .html -end requests, and the rewrite directive rewrites the request to index.php and passes the part before .html as page parameter to PHP. last flag tells Nginx to continue processing the rewrite request. Please make sure to replace /path/to/your/website and unix:/run/php/php7.4-fpm.sock with your actual paths.

Through the above configuration, we successfully implement the two domain names pointing to the same directory and support access to static and pseudo-static pages respectively. Hope this method can help you solve similar problems.
