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