Nginx is a web server that is responsible for handling HTTP requests and responses. If the nginx.service fails, it means that the nginx process has exited with an error code. This error code can be caused by a number of things, such as a configuration error, an incorrect file permissions, or a missing file.

You are here because you have a question about:

  • job for nginx.service failed because the control process exited with error code
  • job for nginx.service failed because the control process exited with error code.

1. Check the nginx error log for more information on the specific error

The steps to check the nginx error log are as follows:

  1. Find the error code in the nginx error log.
  2. Check the nginx configuration file for the error.
  3. Check the nginx service file for the error.
  4. If the errors are found, fix the nginx configuration file or service file.

2. Check the nginx configuration file for any syntax errors

  1. Open the nginx configuration file in a text editor.
  2. Check for any syntax errors.
  3. Correct any errors.
  4. Save the file.
  5. Restart the nginx service.

3. Try reloading nginx instead of restarting it

  1. Reload nginx by running the following command: nginx -t
  2. Check the nginx error log for any errors that might have occurred.
  3. If there are no errors, then it may be necessary to restart nginx.
  4. To restart nginx, run the following command: sudo service nginx restart

If you didn't find success with an option above, then try:

  1. If reloading nginx does not work, try restarting it.
  2. If nginx still does not start up correctly, check for any other processes that may be using port 80 or 443.
  3. If there are no other processes using port 80 or 443, then there may be a problem with the nginx binary itself. Try reinstalling nginx.
