Upgrading Splunk on Ubuntu Linux
Thursday, November 10, 2011 at 11:53 Just a small post with the instructions on upgrading Splunk on Ubuntu Linux.
First download the Splunk update. The Splunk website also gives you the wget command, which you can use directly on the Linux commandline.
The following (bold) commands were all issued from the commandline of the Ubuntu server;
user@server:~/Downloads$ wget -O splunk-4.2.4-110225-linux-2.6-amd64.deb 'http://www.splunk.com/index.php/download_track?file=4.2.4/splunk/linux/splunk-4.2.4-110225-linux-2.6-amd64.deb&ac=&wget=true&name=wget&typed=releases'

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'.
If you want to see what changes will be made before you proceed with the
upgrade, choose 'n'.

The following apps might contain lookup table files that are not exported to other apps:
Splunk_CiscoFirewalls
Such lookup table files could only be used within their source app. To export them globally and allow other apps to access them, add the following stanza to each /opt/splunk/etc/apps/<app_name>/metadata/local.meta file:
[lookups]
export = system
