SplunkWeb Certificates Issue

MHibbin — Thu, 05 Apr 2012 14:53:51 GMT

Recently I noticed I couldn't gain access to Splunkweb on one of Splunk installations. The installation was running fine when I used it previously, and then next day I was met with a certificates issue.

When I stop and start the services I see the following output:

# ./splunk start

Splunk> Australian for grep.

I'm not sure what has gone wrong here... any advice would be appreciated.

Thanks in advance,

Looks like you are trying to generate a certificate against a non-existant root CA. You might need to generate a new root CA. Try reading the following section of the docs:

 http://docs.splunk.com/Documentation/Splunk/4.3.1/admin/Secureaccesstoyoursplunkserverwithssl#Generate_a_new_root_certificate

That corrected the issue... Do you know how I might find the cause of the issue. i.e. what to look for in logs (splunk or system)?

I don't think that there are many (if any) scenarios where Splunk will remove ca.pem. Given that Splunk was trying to generate a new cert on start up, it seems that the server.pem file went missing as well. Any recent changes to server.conf or $SPLUNK_HOME/etc, specifically $SPLUNK_HOME/etc/auth?

I can't think of any changes I made to etc or etc/auth... I normally restrict my changes to etc/apps or etc/system. :S I must have done something outside of Splunk then (though I'm not sure what). Thanks anyway!
