I'm currently upgrading Splunk version from 7.0.3 to 7.2.6.
If I do a manual upgrade it works fine. But if I try to do via automated Jenkins pipeline it's showing that I am installing Splunk for the first time. There is no admin user information & credentials.
Splunk cluster currently in AWS cloud.
Whenever I try to rebuild the stack, it thinks I am installing for the first time. i
Are there any additional processes or steps to follow to overcome this issue?
Please guide me on this. I followed the Splunk documentation exactly.
Thanks in Advance,
Maybe share the script (and/or other relevant details) you're using to install it through Jenkins? Apparently that does something different than a manual upgrade.
Splunk 7.0.3 runs under /etc/init.d while 7.2.6 runs under systemd (depending on your environment).
Under systemd, the splunk unit files are owned and executed as the root user by default (though they invoke the Splunk daemon as the splunk user). These can be viewed/configured at /opt/splunk/etc/splunk-lauch.conf
These settings can additionally be configured at install/upgrade time via CLI, or whatever script/job your build process is using.
I think the issue is more that instead of upgrading, the process being used is installing from scratch in another location. I don't think this question is about the startup scripts.
Refer to Create secure administrator credentials if you are using a fresh install, I find the user-seed.conf the easiest way.
If you want to use systemd (the default on 7.2.6) refer to Splunk systemd unit file in versions 7.2.2 and newer - how do I stop this prompting for the root pas... or use the flag to use init.d as per Configure Splunk Enterprise to start at boot time in particular refer to "Enable boot-start on machines that run systemd" but use the 0 argument to use init.d instead.
My guess is that Splunk is already installed in a custom directory but your automation uses rpm which is trying to install into /opt/splunk. Therefore, you're creating a new install rather than doing an upgrade.
Share more details, like output, screenshots, scripts, etc... and we can help further.
