Checkmk redirect to domain name

[newitadmin (Spencer)]

CMK version: 2.2.0p14
OS version: Ubuntu 22.01

Error message: I am not that experienced with Linux and I am having an issue getting my checkmk host IP accessibly with a domain name. I have included the entry in my DNS server and put the desired web address to point to the checkmk server. However I just get a basic apache page, which is now no longer accessible since attempting to configure ssl. I am just wondering is there any reconfiguration command I can use to configure this stuff - I am a little lost!

Output of “cmk --debug -vvn hostname”: (If it is a problem with checks or plugins)

CMK has no commands or options to configure your systems Apache. The described problems are all Apache related. Empty page problem → configure automatic forwarding inside Apache if no URI for your site is provided.
For the other problem with the HTTPS configuration, your configuration is needed.

First check, whether you get the Apache “It works!” when calling it with the domain name specified in the SSL virtual host, usually the domain name you entered when running certbot.

Then the easiest way to redirect to a site probably is replacing the index.html with one that contains a Javascript Redirect:

Redirection from Apache Default Page to Checkmk Login Page

Quick and dirty, add this to the index.html (Apache default site) in the root folder. <script> window.location.replace("http://myserver/mysite"); </script> Then, when you are tinkering with mod_rewrite and mod_redirect, be sure to match the terminating $ (end of string) to avoid loops, like this mod_redirect only solution: RedirectMatch 301 ^/$ http://myserver/mysite/ RedirectMatch 301 ^$ http://myserver/mysite/

We do this with a rewrite and we also forward to https
Place a file with the following content in conf.d of apache. Replace ‘mysite’ with your site name.

RewriteEngine on
RewriteCond %{HTTPS} !on
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
RedirectMatch 302 "^/$" "/mysite/"
RewriteCond %{REQUEST_METHOD} ^(TRACE|TRACK)
RewriteRule .* - [F]
#LogLevel alert rewrite:trace6
