Hello All,

Can someone help me with the steps to upgrade Splunk Universal Forwarder on Linux machines?

Appreciate your help.

Thanks,

It's very easy.

1) Stop the forwarder

2) Untar the new code.

tar -zxf splunk<<something>>.tgz -C /opt

If necessary, replace /opt with the location of the forwarder on your machines (omit the /SplunkForwarder part).

3) Start the forwarder

Hi

1st you should check if the original UF was installed from tar package as @richgalloway used here or was it installed via package manager (rpm or dep). If later, then you should use the same package manager command like yum/dnf on RedHat based distroes. If you mix those method that will hit you later on.

yes @isoutamo  it was already installed and just needed to upgrade since the UF's are running on very old versions. Do i need to follow the steps which @richgalloway proposed, will it override the previous installation?

If it is installed outside of packet manager then you should follow @richgalloway 's instructions, but if it was installed by packet manager like rpm then you should use that packet manager version. Used packet manager is dependent of Your linux version (Red-hot, Centos, Debian, Ubuntu etc.)
