1. Prerequisites
If you wish to install Checkmk over HTTPS the following prerequisites must be satisfied on your monitoring server — irrespective of your instances:
You must have a valid server certificate.
The apache module mod_ssl is installed and activated.
The server is reachable under HTTPS.
The Rewrite-Module for the webserver is available and loaded.
2. Configuring an HTTPS-connection for an instance
Add the following lines in the section for the VirtualHost:
/etc/apache2/sites-enabled/000-default
RewriteEngine On
RewriteCond %{SERVER_PORT} !^443$
RewriteRule (.*) https://%{HTTP_HOST}/$1 [L]
RequestHeader set X-Forwarded-Proto "https"The VirtualHost-configuration is found in these files — depending on the
distribution being used:
Debian, Ubuntu | /etc/apache2/sites-enabled/000-default(.conf) |
RHEL, CentOS | /etc/httpd/conf.d/ssl.conf |
SLES | /etc/apache2/httpd.conf |
Following a configuration change the webserver must be restarted. The restart commands are different for each distribution:
root@linux# service httpd restart
root@linux# service apache2 restart
root@linux# systemctl restart httpd
root@linux# systemctl restart apache2
