KairosDB is a distributed time-series database that uses Cassandra and Elasticsearch as its storage backend. In this tutorial, we will guide you through the process of installing KairosDB on OpenSUSE.
The first step in installing KairosDB is to ensure that Java is installed on your system. This can be done by running the following command in your terminal:
sudo zypper install java-1_8_0-openjdk
This command will install the latest version of Java 8 on your OpenSUSE system.
Since KairosDB uses Cassandra as its storage backend, we need to install Cassandra on our system. This can be done by running the following command:
sudo zypper install cassandra
This command will install the latest version of Cassandra on your OpenSUSE system.
Now that we have installed Java and Cassandra, we can proceed to install KairosDB. The easiest way to install KairosDB on OpenSUSE is by using the RPM package available on the project's GitHub page.
To download the latest RPM package, run the following command:
wget https://github.com/kairosdb/kairosdb/releases/download/v1.2.1/kairosdb-1.2.1-1.rpm
Once the download is complete, install the RPM package using the following command:
sudo rpm -i kairosdb-1.2.1-1.rpm
This command will install KairosDB on your system.
Before you can start using KairosDB, you need to configure it to use Cassandra as its storage backend. To do this, edit the KairosDB configuration file at /opt/kairosdb/conf/kairosdb.properties using your favorite text editor.
Locate the following lines in the configuration file:
kairosdb.service.datastore=org.kairosdb.datastore.cassandra.CassandraModule
kairosdb.datastore.cassandra.keyspace=kairosdb
kairosdb.datastore.cassandra.host_list=localhost:9160
Change the kairosdb.datastore.cassandra.host_list parameter to match the hostname and port of your Cassandra instance. If you are using the default Cassandra installation, you can leave this parameter as it is.
Save the configuration file and exit your text editor.
You are now ready to start KairosDB. To start the KairosDB service, run the following command:
sudo systemctl start kairosdb
You can verify that KairosDB is running by checking its status:
sudo systemctl status kairosdb
If everything is working correctly, you should see a message indicating that the KairosDB service is running.
Congratulations! You have successfully installed KairosDB on your OpenSUSE system. 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!
