How to Install OpenTSDB on OpenBSD

In this tutorial, we will guide you through the installation process of OpenTSDB on OpenBSD.

OpenTSDB is a distributed, scalable, and high-performance time-series database written in Java. It is designed to store and index large amounts of time-series data and provide easy-to-use APIs for querying and analyzing this data.

Prerequisites

• A server running OpenBSD
• Root access to the server
• Java Development Kit (JDK) 8 or later
• Git client

Step 1: Install JDK

OpenBSD does not come with a preinstalled JDK. Therefore, you need to install it manually.

First, update the package list:

$ sudo pkg_add -u

Then, install the JDK package:

$ sudo pkg_add openjdk8

You can verify the installation by running the following command:

$ java -version

This should print the version of the installed JDK.

Step 2: Install Git

OpenTSDB is hosted on GitHub. Therefore, you need to install Git to download the source code.

Install Git using the following command:

$ sudo pkg_add git

After installation, verify the version of Git by running the following command:

$ git --version

Step 3: Download and Build OpenTSDB

Now, we will download the OpenTSDB source code and build it.

First, clone the OpenTSDB repository using Git:

$ git clone git://github.com/OpenTSDB/opentsdb.git

After cloning, switch to the latest stable version:

$ cd opentsdb
$ git checkout v2.4.0

Then, build and install OpenTSDB using the following command:

$ sh build.sh

This will build the OpenTSDB JAR files and install them in /usr/local/share/opentsdb.

Step 4: Configure OpenTSDB

Now, we need to configure OpenTSDB before we can start using it.

Open the opentsdb.conf file in a text editor:

$ sudo vi /usr/local/share/opentsdb/etc/opentsdb.conf

Update the following settings according to your requirements:

• tsd.network.bind: The IP address or hostname to bind the OpenTSDB service to. Set it to 0.0.0.0 to accept connections from any host.
• tsd.network.port: The port number to listen on. By default, OpenTSDB uses port 4242.
• tsd.core.auto_create_metrics: Set to true to allow OpenTSDB to create new metrics automatically.

Save the file and exit the text editor.

Step 5: Start OpenTSDB

Finally, we can start the OpenTSDB service.

Run the following command to start the OpenTSDB service:

$ sudo /usr/local/share/opentsdb/bin/tsdb tsd --config=/usr/local/share/opentsdb/etc/opentsdb.conf

This will start the OpenTSDB service in the foreground. You can now use OpenTSDB to store and query time-series data.

Conclusion

In this tutorial, we have shown you how to install OpenTSDB on OpenBSD. You can now use OpenTSDB to store, index, and analyze large amounts of 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!
