Hi, my splunk install on /home/splunk, i have try rpm -i -Uvh --prefix=/home splunk-6.5.3-36937ad027d4-linux-2.6-x86_64.rpm, but show "package splunk-6.5.3-36937ad027d4.x86_64 is already installed". i need remove splunk than re-install? thanks.
To upgrade Splunk, you never need to uninstall it and reinstall it again. That's why it´s called an upgrade 😉
First, I would check the list of installed packages.
If you're running Ubuntu 14:
apt list --installed
For older versions:
dpkg --get-selections | grep
If you are running other systems, just try to locate the right commands.
I would also try to make sure that you don´t have any other splunk instances in that machine.
