Among many Time Series databases (TSDB), InfluxDB is able to secure its position in the market. This is because InfluxDB provides many features that give added advantages and make it sustainable in various scenarios. Besides these, it also provides easy installation and configuration. InfluxDB gives flexibility to the user to install a single instance, QuickStart cluster for the non-production environment, and complete cluster solution for a production environment. With all such types of products supported, it would be great to start with a single instance installation.
There are many versions of InfluxDB you can found for download, hence it is important to check which version you are downloading. You should go for Latest version. This blog is dealing version 1.5. At the time of this blog, “InfluxDB 2.0 Beta” is already out.
Before proceeding with installation, your VM should be ready with OS already installed.
Any online installation utility can be utilized which is supported by OS. For RedHat, the YUM installation repository is used here.

This will also create a directory “influxdb” under folder /etc. This folder contains files which is utilized by InfluxDB for any configurational changes. File “influxdb.conf” contains both meta and data sections where anyone can make changes as per one’s environment. configurational changes will be covered in details in next blog which will explain “QuickStart Cluster” installations and configurations.
