Hey there! As a newbie in the world of CentOS7, I appreciate you sharing this guide on how to install Splunk 7. It looks like setting up the hostname and configuring NTP are crucial steps in the process. By the way, I heard that CentOS 7 has reached its end of life, which means no more updates or patches will be released. However, I also learned that TuxCare offers extended support for CentOS 7. You might want to check out their website https://tuxcare.com/extended-lifecycle-support/centos-7-extended-support/ to keep your system secure and up-to-date.
