How to start the Splunk service on Red Hat Linux?

Alan_Bradley — Wed, 04 Nov 2020 20:13:14 GMT

I installed the Splunk Linux version today (rpm version) but I don't know how to start Splunk service. I tried to input command service Splunk start and /etc/init.d/splunk start but these services did not have Linux. How can I start Splunk service?

You will want to run the command: $SPLUNK_HOME/bin/splunk start

Reference: http://docs.splunk.com/Documentation/Splunk/5.0/Installation/StartSplunkforthefirsttime

Better answer:
$SPLUNK_HOME/bin/splunk enable boot-start
This creates an init.d service file.

$SPLUNK_HOME/bin/splunk enable boot-start

Installs a service file in /etc/init.d that supports start|stop|restart|status

If it is RHEL 7.x + I would recommend using systemd to manage the splunk service:

$SPLUNK_HOME/bin/splunk enable boot-start -systemd-managed 1 -user <username> -group <groupname>

https://docs.splunk.com/Documentation/Splunk/8.1.0/Admin/RunSplunkassystemdservice

This will create a file in /etc/systemd/system/Splunkd.service and I replace the contents of that with:

[Unit] After=network.target [Service] Type=simple Restart=always ExecStart= /opt/splunk/bin/splunk _internal_launch_under_systemd ExecStop = /opt/splunk/bin/splunk stop ExecReload = /opt/splunk/bin/splunk restart LimitCORE = 0 LimitFSIZE = infinity LimitDATA = infinity LimitNPROC = 20480 LimitNOFILE = 65536 TimeoutSec = 300 SuccessExitStatus=51 52 RestartPreventExitStatus=51 RestartForceExitStatus=52 Delegate=true MemoryLimit=100G CPUShares=1024 PermissionsStartOnly=true ExecStartPost=/bin/bash -c "chown -R splunk:splunk /sys/fs/cgroup/cpu/system.slice/%n" ExecStartPost=/bin/bash -c "chown -R splunk:splunk /sys/fs/cgroup/memory/system.slice/%n" [Install] WantedBy=multi-user.target

This file will handle required ulimit settings and deal with permissions per Splunk's env specs. Also note that I am running Splunk as the linux user splunk which you can change should you want to. If you choose to do this make sure you refresh systemd daemon:

systemctl daemon-reload

I prefer running Splunk using systemd instead of the legacy init.d as there is more functionality and I would assume it is going to be more supported moving forward.
