How to Install ZooKeeper on Manjaro

ZooKeeper is a distributed coordination service for maintaining and synchronizing configuration information, naming, providing distributed synchronization, and group services. In this tutorial, we will walk you through the installation process of ZooKeeper on Manjaro.

Prerequisites

Before installing ZooKeeper, ensure you have the following:

  • A terminal window / Command line interface
  • wget
  • Java JDK 8 or Later

Step 1: Download ZooKeeper

First, you need to download the latest stable version of ZooKeeper. To download ZooKeeper, follow the steps given below:

  1. Visit the ZooKeeper Download page.
  2. Under the Latest Stable Release section, click the link of the Apache mirror close to your location.
  3. When prompted, select the appropriate mirror to begin the download.

Alternatively, you can use the following command to download ZooKeeper:

wget https://downloads.apache.org/zookeeper/zookeeper-3.7.0/apache-zookeeper-3.7.0-bin.tar.gz

Step 2: Extract ZooKeeper Package

In this step, extract the downloaded ZooKeeper package using the following command:

tar -xzvf apache-zookeeper-3.7.0-bin.tar.gz

Step 3: Configure ZooKeeper

By default, ZooKeeper comes with a sample configuration file conf/zoo_sample.cfg. You need to rename it as zoo.cfg using the following command:

cp conf/zoo_sample.cfg conf/zoo.cfg

Step 4: Open Firewall for ZooKeeper

If you have an active firewall on your Manjaro system, you need to allow ZooKeeper ports through the firewall using the following command:

sudo ufw allow 2181/tcp

Alternatively, you can disable the firewall using the following command:

sudo ufw disable

Step 5: Start ZooKeeper Service

To start the ZooKeeper service, navigate to the ZooKeeper directory and use the following command:

bin/zkServer.sh start

If you want to start the ZooKeeper service in the background, use the following command instead:

bin/zkServer.sh start 2>&1 >/dev/null &

Step 6: Check ZooKeeper Status

To check the status of the ZooKeeper service, use the following command:

bin/zkServer.sh status

This will display the status of the ZooKeeper service, such as "Mode: standalone" or "Mode: leader".

Congratulations! You have successfully installed ZooKeeper on Manjaro. You can now use ZooKeeper for your distributed applications.
