Update Splunk 6.0 to 6.0.3 on FreeBSD
A new version of splunk came out and I decided to apply it (here are the release notes, it mostly fixes the heartbleed vulnerability). The update process is covered in detail here. I was using a FreeBSD machine to host Splunk (check out a previous post on that here) and I first needed to install the pkg_install port in order to install the old style package.
Install pkg_install on FreeBSD
The install itself is pretty easy:
cd /usr/ports/ports-mgmt/pkg_install sudo make install
Backup Original Splunk Install
To be safe let’s go ahead and create a backup of the current setup. To do this, first stop the service:
sudo service splunk stop
Then to the splunk home location and tar up the install:
cd /opt sudo tar cpjvf splunk_4_15_14.tar.bz splunk
Update Splunk 6.0 to 6.0.3
After the backup is finished, download the package from splunk site and then install it:
sudo pkg_add -f splunk-6.0.3-204106-freebsd-7.3-amd64.tgz .. .. This looks like an upgrade of an existing Splunk Server. Attempting to stop the installed Splunk Server... splunkweb is not running. splunkd is not running. complete
Since it was an old style of the package, there were a couple of warnings, but it went through fine (I also ended up using the -f flag to force the install, since the old version of the package was already installed).
To check what changes will be made, start the service and you will see the following:
sudo /opt/splunk/bin/splunk start --accept-license
and you will see the following:
This appears to be an upgrade of Splunk. --------------------------------------------------------------------------------) Splunk has detected an older version of Splunk installed on this machine. To finish upgrading to the new version, Splunk's installer will automatically update and alter your current configuration files. Deprecated configuration files will be renamed with a .deprecated extension. You can choose to preview the changes that will be made to your configuration files before proceeding with the migration and upgrade: If you want to migrate and upgrade without previewing the changes that will be made to your existing configuration files, choose 'y'.

I looked over the files and made sure no files that I modified before, were getting replaced. After confirming that, I ran the same command and then selected ‘y’ to do the actual install:

That time around it actually applied the update. I logged into splunk and all of the reports and applications that I was using were still working as expected.
