How to Install KairosDB on Alpine Linux

KairosDB is a powerful open-source time-series database that is designed to be scalable and provide high performance. In this tutorial, we will guide you through the process of installing KairosDB on Alpine Linux Latest.

Prerequisites

Before you begin, please make sure that you have the following:

A server running Alpine Linux Latest
A non-root user with sudo privileges
Java 8 or higher installed on your server

Step 1: Install Apache Cassandra

KairosDB uses Apache Cassandra as its backend database. Therefore, we need to install Cassandra first. Run the following commands to install Apache Cassandra:

sudo apk update
sudo apk add openjdk8-jre
sudo apk add cassandra

Once the installation is complete, start the Cassandra service using the following command:

sudo rc-update add cassandra
sudo service cassandra start

Step 2: Install KairosDB

Next, we will install KairosDB. Run the following command to download and install KairosDB:

wget https://github.com/kairosdb/kairosdb/releases/download/v1.2.1/kairosdb-1.2.1-1.tar.gz
tar zxvf kairosdb-1.2.1-1.tar.gz
sudo mv kairosdb /opt/

Step 3: Configure KairosDB

Now that KairosDB is installed, we need to configure it. Run the following command to create a configuration file for KairosDB:

sudo nano /opt/kairosdb/conf/kairosdb.properties

Edit the file and update the following lines to match your configuration:

kairosdb.service.datastore=org.kairosdb.datastore.cassandra.CassandraModule
kairosdb.jetty.port=8080

Save and close the file.

Next, we need to create a Cassandra keyspace for KairosDB using the following command:

cqlsh -e "CREATE KEYSPACE kairos WITH REPLICATION = {'class': 'SimpleStrategy', 'replication_factor': 1};"

Finally, start KairosDB by running the following command:

/opt/kairosdb/bin/kairosdb.sh start

Step 4: Verify the Installation

To verify that KairosDB is installed and running correctly, open a web browser and navigate to:

http://<your server's IP or hostname>:8080/api/v1/version

You should see a JSON response containing the version number of KairosDB.

Congratulations! You have successfully installed KairosDB on Alpine Linux Latest. You can now start using KairosDB to store and query time-series data.
