Configured apache2 virtual hosts show default page

When you set up Apache2 web server on your machine, one of the common issues you might encounter is that even after configuring your virtual hosts, the server may still display the default Apache page instead of your website. This issue can arise from several misconfigurations or oversight in your settings.

Understanding the Problem

The original problem statement was: "Configured apache2 virtual hosts show default page."

This can be rephrased for clarity: "Even after configuring virtual hosts in Apache2, the server continues to display the default page instead of the intended website."

Original Code for the Problem

Here’s a typical configuration snippet for an Apache2 virtual host that could lead to such an issue if not set up properly:

<VirtualHost *:80>
    ServerName example.com
    DocumentRoot /var/www/example
    <Directory /var/www/example>
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

In the above example, if the configuration is not correct, you might still end up seeing the default Apache page.

Causes of the Default Page Displaying

Misconfigured Virtual Host: If the DocumentRoot is pointing to a directory that does not contain the desired website files, Apache will serve the default page instead.
Incorrect ServerName: If the ServerName does not match the domain you are trying to access, Apache may not know to route your request to the correct virtual host.
Port Conflicts: If multiple virtual hosts are listening on the same port, it could create confusion for the server, leading to serving the default page.
Configuration File Not Enabled: The virtual host file may not be enabled. Apache requires that virtual host configurations are enabled using a2ensite.
Cached Responses: Sometimes, your browser may cache the default page. Clearing your cache can help in seeing the changes you made.
Apache Not Restarted: After making changes to the configuration files, you must restart or reload Apache for the changes to take effect.

Solutions

Verify Configuration

Check the Syntax: Use the command below to verify that there are no syntax errors in your Apache configuration.
```
apachectl configtest
```
Ensure DocumentRoot Exists: Double-check that the directory you specified in DocumentRoot exists and contains the correct index.html or index.php file.
Verify ServerName: Make sure that the ServerName matches the domain you are accessing. If you’re testing locally, also consider adding an entry to your /etc/hosts file:
```
127.0.0.1   example.com
```

Enable and Restart the Virtual Host

Enable your site configuration:
```
sudo a2ensite example.conf
```
Restart Apache to apply the changes:
```
sudo systemctl restart apache2
```

Additional Tips

Log Files: Check Apache's error logs for any issues that might give clues to why the default page is still being served. Logs are often located in /var/log/apache2/error.log.
Port Conflicts: If using virtual hosts on different ports, ensure that Apache is configured to listen to those ports:
```
Listen 80
Listen 8080
```

Practical Example

Here’s a practical example of a properly configured virtual host:

<VirtualHost *:80>
    ServerName mywebsite.local
    DocumentRoot /var/www/mywebsite
    <Directory /var/www/mywebsite>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

Testing It Out

Add the following line to your /etc/hosts file to test locally:
```
127.0.0.1   mywebsite.local
```
Save your changes, restart Apache, and access http://mywebsite.local in your browser to verify that the correct page is displayed.

Conclusion

If your configured Apache2 virtual hosts are showing the default page instead of the intended content, double-checking the configuration, validating directories, enabling the site, and checking the server name can resolve the issue effectively. Always ensure to restart Apache after making any changes to the configuration.

Following these steps will ensure a proper setup for your Apache2 virtual hosts, allowing you to effectively manage multiple sites on a single server.
