When managing an Apache web server, it’s essential to know where to locate the error log, especially when troubleshooting issues. In Ubuntu 24.04, Apache logs are crucial for identifying problems related to your server’s configuration or application performance.

By default, Apache logs errors to a specific file. To find the Apache error log in Ubuntu 24.04, follow these steps:

  1. Default Log Location
    The error log file is located at:
   /var/log/apache2/error.log
  1. How to Access the Log
    You can view the error log using any text editor or by running the following command in your terminal:
   sudo tail -f /var/log/apache2/error.log

This command shows the latest entries in real-time.

  1. Custom Log Locations
    If your server uses virtual hosts or custom configurations, the error log path might differ. You can check the specific log path by inspecting your Apache configuration files, typically located in /etc/apache2/sites-available/.
  2. Error Log Rotation
    Ubuntu uses a log rotation system to manage log size. Older logs are archived and compressed automatically. You can find these rotated logs in the same directory with a .gz extension, such as error.log.1.gz.
