Install on Linux
You can install Splunk on Linux using RPM or DEB packages, or a tar file.
Note: If you want to install the Splunk universal forwarder, see the Distributed Deployment manual: "Universal forwarder deployment overview". Unlike Splunk heavy and light forwarders, which are full Splunk instances with some features changed or disabled, the universal forwarder is an entirely separate executable, with its own set of installation procedures. For an introduction to forwarders, see "About forwarding and receiving".
If you are upgrading, review "How to upgrade Splunk" for instructions and migration considerations before proceeding.
RedHat RPM install
To install the Splunk RPM in the default directory
rpm -i splunk_package_name.rpm
To install Splunk in a different directory, use the
rpm -i --prefix=/opt/new_directory splunk_package_name.rpm
To upgrade an existing Splunk installation that resides in /opt/splunk using the RPM:
rpm -U splunk_package_name.rpm
To upgrade an existing Splunk installation that was done in a different directory, use the
rpm -U --prefix=/opt/existing_directory splunk_package_name.rpm
Note: If you do not specify with
--prefix for your existing directory, rpm will install in the default location of
For example, to upgrade to the existing directory of
$SPLUNK_HOME=/opt/apps/splunk enter the following:
rpm -U --prefix=/opt/apps splunk_package_name.rpm
If you want to automate your RPM install with kickstart, add the following to your kickstart file:
./splunk start --accept-license ./splunk enable boot-start
Note: The second line is optional for the kickstart file.
Debian DEB install
To install the Splunk DEB package:
dpkg -i splunk_package_name.deb
Note: You can only install the Splunk DEB package in the default location,
Tar file install
To install Splunk on a Linux system, expand the tarball into an appropriate directory using the
tar xvzf splunk_package_name.tgz
The default install directory is
splunk in the current working directory. To install into
/opt/splunk, use the following command:
tar xvzf splunk_package_name.tgz -C /opt
Note: When you install Splunk with a tarball:
- Some non-GNU versions of
tarmight not have the
-Cargument available. In this case, if you want to install in
/optor place the tarball in
/optbefore running the
tarcommand. This method will work for any accessible directory on your machine's filesystem.
- Splunk does not create the
splunkuser automatically. If you want Splunk to run as a specific user, you must create the user manually before installing.
- Ensure that the disk partition has enough space to hold the uncompressed volume of the data you plan to keep indexed.
