CentOS 6.5 – How to upgrade Splunk

Existing install : 6.1.1-207789
Upgrade : 6.1.2.213098

  • First, create a backup of the entire Splunk folder. In theory, the /etc and it’s sub-folders would be sufficient, but a full backup can’t hurt.
  • Download the new source files. The Splunk developers have been kind enough to provide a wget friendly link. Simply click the “Download” button and look at the next page.
  • Extract (tar -xvf) the splunk folder.
  • Copy that entire folder over your previous installation. You can use ” yes | cp -r source_path destination_path” to answer yes to all the overwrite prompts.
  • That’s it!
