ZooKeeper is a popular distributed coordination service that can be used to maintain configuration information, synchronize distributed processes, and provide group messaging services. In this tutorial, we will be walking through the installation process of ZooKeeper on NetBSD.
Before we begin, make sure that you have administrative privileges to the NetBSD machine you are installing ZooKeeper on. Additionally, ensure that you have a stable internet connection and a working installation of Java.
Begin by downloading the latest stable release of ZooKeeper from the Apache ZooKeeper website.
$ curl -O https://downloads.apache.org/zookeeper/zookeeper-3.7.0/apache-zookeeper-3.7.0-bin.tar.gz
Extract the downloaded archive file into the appropriate directory in your NetBSD system. You may choose to extract it to /usr/local.
$ tar -xzvf apache-zookeeper-3.7.0-bin.tar.gz -C /usr/local/
Navigate to the extracted ZooKeeper directory.
$ cd /usr/local/apache-zookeeper-3.7.0-bin/
Create a copy of the default zoo_sample.cfg file and name it zoo.cfg.
$ cp conf/zoo_sample.cfg conf/zoo.cfg
Use an editor, such as nano or vim, to modify the zoo.cfg file.
$ nano conf/zoo.cfg
In the file, set the dataDir field to the directory you want to use for storing data and logs.
dataDir=/var/zookeeper
Start the ZooKeeper server using the zkServer.sh script.
$ bin/zkServer.sh start
By default, ZooKeeper will run on port 2181.
You can verify that the server is running by checking the logs.
$ tail -f /var/zookeeper/zookeeper.out
Congratulations! You have successfully installed and configured ZooKeeper on NetBSD. You are now ready to use ZooKeeper to coordinate your distributed 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!
