Hello everyone, please I try to start an apache2 server that I just installed but it refuses. At the beginning it worked well. After installing the Nagios monitoring server on it, it refuses to start. Everything is on an Ubuntu 20.04 virtual server

Hey there!

It looks like there may be a syntax error in your configuration file /etc/apache2/conf-enabled/nagios4-cgi.conf. I’d recommend you check that file and verify line 37 is correct and does not have any syntax errors.

The apache logs in /var/log/apache2 may also have more details on the error.

Hope it helps!
Nate

Hello, @koboni2000

As the message says there is a SyntaxError in your Apache configuration file.

Syntax error on line 37 of /etc/apache2/conf-enabled/nagios4-cgi.conf

You can open the file with a text editor like vi, vim or nano and sort out the syntax error:

  • vim +37 /etc/apache2/conf-enabled/nagios4-cgi.conf

If you’re not familiar with editing files via ssh you can check out these articles:

You can also share the output of the file (line 37) here and we can check this together.
