How Do I Fix Web Server Failed to Start Port 8080 Was Already in Use Mac?

If you’re encountering the error message “Web Server Failed to Start Port 8080 Was Already in Use” on your Mac, don’t worry – there are a few simple steps you can take to resolve this issue. This error typically occurs when another application or process is already using port 8080, preventing your web server from starting properly. Let’s explore some possible solutions:

1. Find the Process Using Port 8080

To begin troubleshooting, we need to identify the process that is currently using port 8080. Open a terminal window and enter the following command:

lsof -i :8080

This command will display information about the process using port 8080. Take note of the Process ID (PID) associated with it.

2. Stop the Process Using Port 8080

Now that we know which process is causing the conflict, we can stop it by entering the following command in the terminal:

kill PID

Replace ‘PID’ with the actual Process ID you obtained from the previous step. This command will terminate the process and free up port 8080.

3. Change Web Server Configuration

If you’re unable to stop the conflicting process or if it’s an essential system service, you can change your web server’s configuration to use a different port instead of 8080.

  • Apache: Locate your Apache configuration file (httpd.conf), usually found in /etc/apache2/. Open it with a text editor, search for “Listen” directive and change the port number to an available one (e.g. 8888).

    Save the file and restart Apache.

  • Nginx: Open your Nginx configuration file (nginx.conf) with a text editor, locate the ‘listen’ directive and modify the port number to a different value (e. Save the file and restart Nginx.

4. Check for Other Programs Using Port 8080

It’s possible that other programs or services on your Mac are also using port 8080.

To identify them, you can use several methods:

  • Activity Monitor: Open Activity Monitor from your Applications/Utilities folder, search for processes using “8080” in the search bar, and manually stop any relevant processes.
  • Netstat: In the terminal, run the command netstat -an | grep LISTEN | grep ":8080". This will display processes listening on port 8080. Stop any unwanted processes accordingly.

5. Use a Different Web Server

If you’re still unable to resolve the issue, consider using a different web server software that doesn’t rely on port 8080 by default. There are various alternatives available, such as Lighttpd or Tomcat.

Note: Changing ports may require adjusting firewall settings or updating URLs in your applications to reflect the new port configuration.

By following these steps, you should be able to fix the “Web Server Failed to Start Port 8080 Was Already in Use” error on your Mac and get your web server up and running smoothly again!
