Troubleshoot Apache Startup Problems

Are you having difficulty getting your Apache server started? Here is a list of common problems and their solutions.

The information in this document is based on this ApacheFriends community forum thread.

Another Web Server Daemon is Already Running

XAMPP displays a message like:

Another web server daemon is already running.

To solve this problem, follow these steps:

Open a new Linux terminal.
Use the netstat command to identify which other service is currently using port 80 and/or 443.
```
sudo netstat -tunap | grep LISTEN
```
Terminate services currently using those ports - for example, using a command like service [process-name] stop.

You should now be able to start Apache successfully.

If the problem persists even after performing these steps, refer to this source thread and this forum post for alternative solutions.
