Is it owned by the same user/group as the splunkd process? Have you used "chown -R" for your splunk home to be sure?

Kind Regards

Any luck with that?

Hey,

do you execute everything in context of user suk? Usually you have a seperate user and you kind of want to install splunk in /opt/splunk. To do this automagically (and also set SPLUNK_HOME) you can install splunk using your package manager (DEB/RPM):
http://docs.splunk.com/Documentation/Splunk/7.2.1/SearchTutorial/InstallSplunk#Install_the_Splunk_Enterprise_RPM

To your problem: This directory seems broken:
/home/suk/opt/splunk/$SPLUNK_HOME/etc/auth/splunkweb/

It should be: $SPLUNK_HOME/etc/auth/splunkweb/ with $SPLUNK_HOME being set.

/home/suk/opt/splunk/etc/auth/splunkweb/ as absolute path.

What does echo "$SPLUNK_HOME"print?

Cheerz,
Björn

I know this is old but while setting up a lab to do some clustering I ran into this issue after making some of the "appropriate settings". To get around this for the sake of getting the lab stood up I just removed that part of the line in the:

splunk_dir/etc/system/local/web.conf (have to copy this from /default or you can hand type everything out)

for the privKeyPath and serverCert, I basically removed the $SPLUNK_HOME part so that it was just

etc/auth/splunkweb/privkey.pem
etc/auth/splunkweb/cert.pem

(running a cmaster, dserver and fwdr on one server, an indexer cluster on one server, and search heads on another)
Would I do this for a single install or enterprise installation - heck no. This is only for personal labbing.

In your case:
File causing error and where you should fix - /home/suk/opt/splunk/etc/system/default/web.conf
copy that to
/home/suk/opt/splunk/etc/system/local/

imagine in that web.conf file you have
privKeyPath = $SPLUNK_HOME/etc/auth/splunkweb/privkey.pe,
serverCert = $SPLUNK_HOME/etc/auth/splunkweb/cert.pem

you would want (if you are just trying to get it to work)
privKeyPath = etc/auth/splunkweb/privkey.pem
serverCert = etc/auth/splunkweb/cert.pem

Previous comment is right, you want to install in the /opt/splunk - for me I wanted to "mock up" the lab environment for cluster admin so...

Hey @fearofcasanova ,

Thanks for the answer, this worked like a charm and now my splunkweb is up and running.

Thanks,
