Laravel多独立域名（非子域名）同服务器无跳转展示页面方案

First, make sure you have mod_rewrite enabled on your Apache server. If you’re on Debian/Ubuntu, run sudo a2enmod rewrite and restart Apache with sudo systemctl restart apache2 to apply the change.

Step 1: Set Up Virtual Hosts for Client Domains #

Create a separate Apache configuration file for each client domain (e.g., client1.com.conf, client2.com.conf). Here’s the template for client1.com:

<VirtualHost *:80>
    ServerName client1.com
    ServerAlias www.client1.com

    # Point to your main Laravel project's public directory
    DocumentRoot /var/www/example.com/public

    <Directory /var/www/example.com/public>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Require all granted

        # Internal rewrite logic to map client domain requests to the subpath
        RewriteEngine On
        RewriteBase /

        # Rewrite non-existent files/dirs to the client subpath
        RewriteCond %{REQUEST_FILENAME} !-f
        RewriteCond %{REQUEST_FILENAME} !-d
        RewriteRule ^(.*)$ /client1.com/$1 [L]

        # Serve existing assets (CSS/JS/images) directly from the client subdirectory
        RewriteCond %{REQUEST_URI} !^/client1.com/
        RewriteCond %{REQUEST_FILENAME} -f
        RewriteRule ^(.*)$ /client1.com/$1 [L]
    </Directory>

    # Optional logging for debugging
    ErrorLog ${APACHE_LOG_DIR}/client1.com-error.log
    CustomLog ${APACHE_LOG_DIR}/client1.com-access.log combined
</VirtualHost>

Key Details: #

• Replace /var/www/example.com/public with the actual path to your Laravel project’s public folder.
• The [L] flag tells Apache to stop processing further rewrite rules after this one, ensuring the internal redirect happens without changing the user’s browser URL.

Step 2: Add HTTPS Support (Recommended) #

If you’re using SSL (which you should), create a similar config for port 443 with your SSL certificates:

<VirtualHost *:443>
    ServerName client1.com
    ServerAlias www.client1.com

    DocumentRoot /var/www/example.com/public

    <Directory /var/www/example.com/public>
        # Same rewrite rules as the HTTP config
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Require all granted

        RewriteEngine On
        RewriteBase /

        RewriteCond %{REQUEST_FILENAME} !-f
        RewriteCond %{REQUEST_FILENAME} !-d
        RewriteRule ^(.*)$ /client1.com/$1 [L]

        RewriteCond %{REQUEST_URI} !^/client1.com/
        RewriteCond %{REQUEST_FILENAME} -f
        RewriteRule ^(.*)$ /client1.com/$1 [L]
    </Directory>

    # SSL certificate paths
    SSLEngine On
    SSLCertificateFile /path/to/your/client1.crt
    SSLCertificateKeyFile /path/to/your/client1.key
    SSLCertificateChainFile /path/to/your/chain.crt # If required by your SSL provider

    ErrorLog ${APACHE_LOG_DIR}/client1.com-ssl-error.log
    CustomLog ${APACHE_LOG_DIR}/client1.com-ssl-access.log combined
</VirtualHost>

Step 3: Laravel Route & URL Adjustments #

• Route Setup: Ensure your Laravel routes are configured to handle the client subpath. For example:

  Route::prefix('client1.com')->group(function () {
      Route::get('/', function () {
          return view('clients.client1.home');
      });
      // Add other client-specific routes here
  });
  

• Dynamic APP_URL: To generate correct URLs in views (e.g., for assets or links), add a middleware to set the APP_URL based on the request domain:

  // app/Http/Middleware/SetClientAppUrl.php
  public function handle(Request $request, Closure $next)
  {
      $protocol = $request->isSecure() ? 'https://' : 'http://';
      config(['app.url' => $protocol . $request->getHost()]);
      return $next($request);
  }
  

  Register this middleware in app/Http/Kernel.php to apply it to all requests.

Final Steps #

1. Enable the new virtual host files with sudo a2ensite client1.com.conf (repeat for each client domain).
2. Restart Apache again to apply all changes: sudo systemctl restart apache2.
3. Test by visiting client1.com in your browser—you’ll see the content from example.com/client1.com without any URL redirect.
