Apache Flume is a distributed, reliable, and available system for efficiently collecting, aggregating, and moving large amounts of data from one place to another. In this tutorial, you will learn how to install Flume on OpenBSD.
Before you begin, ensure that you have the following:
Flume is a Java-based application, so you need to ensure you have Java installed on your OpenBSD system. To install Java, open the terminal and run:
$ doas pkg_add openjdk-11.0.10
This will install OpenJDK 11 on your OpenBSD system.
Next, download Flume from the Apache Flume website. You can do this using the wget command:
$ wget https://downloads.apache.org/flume/1.9.0/apache-flume-1.9.0-bin.tar.gz
Once the download has completed, extract the downloaded file using the tar command:
$ tar -xvzf apache-flume-1.9.0-bin.tar.gz
This will extract the contents of the downloaded file to a new directory named apache-flume-1.9.0-bin.
To run Flume, you need to set the FLUME_HOME and PATH environment variables.
Add the following lines to the end of the ~/.profile file:
export FLUME_HOME="/path/to/apache-flume-1.9.0-bin"
export PATH="$PATH:$FLUME_HOME/bin"
Replace /path/to/apache-flume-1.9.0-bin with the actual path to the directory where you extracted Flume.
Now that Flume is installed and the environment variables are set up, you can start Flume. To do so, open the terminal and run:
$ flume-ng agent --conf $FLUME_HOME/conf --conf-file $FLUME_HOME/conf/flume.conf --name my-agent -Dflume.root.logger=INFO,console
This command starts Flume with the default configuration file in the conf directory. You can create your own configuration file if needed.
In this tutorial, you have learned how to install Flume on OpenBSD. With Flume, you can efficiently collect, aggregate, and move large amounts of data from various sources to other systems.
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!
