In the last blog, we discussed how to choose between a single or clustered environment. Read our first blog here!
Regardless of which one you choose, you must install Splunk using a user other than root to prevent the Splunk platform from being used in a security breach.
The following instructions have to be done in sequence:
Step 1: Create a Splunk user
We will first create a separate user for Splunk and add a group for that user.
useradd -d /opt/Splunk -m -g Splunk Splunk
Step 2: Download and Extract Splunk
The easiest way to download Splunk on a Linux machine is with wget. To get the URL do the following:
- Go to https://www.splunk.com/en_us/download/splunk-enterprise.html
- Log in with your Splunk credential.
- Select to download the Linux .tgz file. This will download the latest version of Splunk. To download an older version click on the “Older Releases” link.
- Once you click download, it will start downloading Splunk on your browser. Stop downloading.
- On the newly opened page, you will see Link for useful tools from there select “Download via Command Line (wget)” to get the URL.
- Select and copy the full wget link.
Open a Linux ssh session and paste in /opt/ directory. This will download the Splunk tgz file.
Step 3: Start Splunk
Make sure from this point onwards you always use Splunk user to do any activity in the backend related to Splunk.
Change ownership of the Splunk directory.
Chown -R splunk:splunk /opt/splunk
Change user to Splunk.
/opt/splunk/bin/splunk start –accept-license
It will ask you to enter the admin username and password.
Step 4: Enable Splunk boot start.
/opt/splunk/bin/splunk enable boot-start -user splunk
Step 5: Use Splunk
Open your browser and go to the URL below and you will be able to use Splunk.
Use the username and password you entered in step-3 while starting Splunk.
