ZooKeeper is a distributed coordination service used for managing large systems. In this tutorial, we will be walking you through the steps of installing ZooKeeper on a Fedora CoreOS system.
ZooKeeper requires Java to run. Fedora CoreOS does not come with Java pre-installed. Therefore, we need to install Java before we can proceed with the ZooKeeper installation.
To install Java, run the following command in the terminal:
sudo dnf install java-latest-openjdk
To download and install ZooKeeper, follow these steps:
Download the ZooKeeper compressed file from the official website:
wget https://downloads.apache.org/zookeeper/zookeeper-3.7.0/apache-zookeeper-3.7.0-bin.tar.gz
Extract the downloaded file using the following command:
tar -xzvf apache-zookeeper-3.7.0-bin.tar.gz
Move the extracted directory to the desired location. In this example, we will be moving it to the /opt/ directory:
sudo mv apache-zookeeper-3.7.0-bin /opt/zookeeper
Configure ZooKeeper by creating the zoo.cfg file in the conf directory:
sudo cp /opt/zookeeper/conf/zoo_sample.cfg /opt/zookeeper/conf/zoo.cfg
You can configure ZooKeeper by editing the zoo.cfg file.
Create a data directory for ZooKeeper:
sudo mkdir /var/lib/zookeeper
Change the ownership of the directory:
sudo chown -R $USER:$USER /var/lib/zookeeper
To start ZooKeeper, run the following command in the terminal:
/opt/zookeeper/bin/zkServer.sh start
You should see the following message:
ZooKeeper JMX enabled by default
Using config: /opt/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
Congratulations, you have successfully installed ZooKeeper on your Fedora CoreOS system. You can now start exploring the capabilities of ZooKeeper and its various use cases.
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!
