how to switch to a wildcard certificate on Nagios XI?

[gornm565]

When I go to my Nagios Xi GUI right now, I always get an error: "There is a problem with this website’s security certificate." We have a wildcard certificate for our domain. How do we install it to get rid of these warnings?

When you go to the URL, are you using the domain the certificate is for (not the servers IP)?

If so, have you added the certificate and chain to the httpd configuration files?

Can you share your httpd settings you changed?

I haven't modified it yet. The certificate being used is still the default one "localhost.localdomain".

You would need to modify the ssl.conf to point to your wildcard certificate file and certificate key file
something like this

Code: Select all

    SSLCertificateChainFile /etc/pki/tls/certs/essential.crt
    SSLCertificateFile /etc/pki/tls/certs/xxxxxxxxxxxxxxx.crt
    SSLCertificateKeyFile /etc/pki/tls/private/xxxxxxxxxxxxxxx.key

When I download our wildcard certificate from GoDaddy, I get 2 files, the crt file and the crt bundle. Your reply also mentions a key file. How do I get that one?

I would have been created when you created the CSR that you sent to GoDaddy
