KairosDB is a distributed time-series database that runs on top of Apache Cassandra, which is designed to store and index timestamped data at a massive scale. In this tutorial, we’ll go through the steps involved in installing KairosDB on nixOS Latest.
Before we begin, you’ll need the following:
It is always a good practice to update your system to ensure that the latest security patches and updates are installed.
You can do this by running the following command:
sudo nixos-rebuild switch --upgrade
KairosDB is a Java-based application. Therefore, Java must be installed on our system before we proceed with the installation. Here, we will install OpenJDK 11, which is the latest Java version.
You can install OpenJDK 11 by running the following command:
nix-env -iA nixpkgs.openjdk11
As mentioned before, KairosDB is built on top of Apache Cassandra. Hence, we must first install it.
You can install Cassandra by running the following command:
nix-env -iA nixpkgs.cassandra
Finally, we can proceed to install KairosDB itself.
You can install KairosDB by following these steps:
git clone https://github.com/kairosdb/kairosdb.git
cd kairosdb
./bin/build.sh package
nix-env -iA kairosdb -f kairosdb-${version}.tar.gz
Now that we've installed KairosDB, we can start it up by running:
systemctl start kairosdb
In this tutorial, we have shown you how to install KairosDB on nixOS Latest. You can now start using KairosDB to store and index timestamped data.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
