This requires creating an account on the Oracle website. When installing Oracle Java on CentOS 8, make sure to download directly from the official source, Oracle. For OpenJDK 8 headless run: sudo yum install java-1.8.0-openjdk-headless Install Oracle JDK on CentOS 8. You can study these options after you have successfully installed and have graphed your first statistics. sudo yum install java-11-openjdk-headless. Both InfluxDB and Grafana have a text config file for advanced options.Assuming you have the correct time or an Network Time Protocol process and you are not going to change the hostname after install (possible but not covered here).
We will be using default network ports 8086 for InfluxDB and 3000 for Grafana.For an early easy successful first time, use InfluxDB 1.8 I think version 2 has excellent compatibility with an earlier version and work fine. I have not tested InfluxDB version 2 yet.Once downloaded, we can run the mvn -version to verify our installation. This will take a few minutes to download. We run the command sudo apt-get install maven to install the latest Apache Maven. For POWER8 go here: and POWER9 servers the latest versions here and The Maven package always comes with the latest Apache Maven.Latest versions for InfluxDB and Grafana (at the time of writing this blog) InfluxDB 1.8.3 and Grafana 7.3.6.Alternatively, you could download and copy over the installation files by hand. If this is a quick proto-type to throw away then even 64GB is fine. I suggest a root file system of 1 TB or more. It is your option to set-up a separate file system for this data. Alternatively, use a large root file system. We are going to take all the default settings including using the root file system for the InfluxDB data.A freshly installed Red Hat 8.2 and you have system admin access.
