How to Install Couchbase Server on Ubuntu 22.04 and 20.04

A Comprehensive Guide to Installing Couchbase Server on Ubuntu 22.04 and 20.04

Couchbase Server stands out as a powerful, distributed NoSQL cloud database. Renowned for its performance, scalability, and flexibility, it’s a popular choice for modern web, mobile, and IoT applications. If you’re running an Ubuntu environment, getting Couchbase Server up and running is a straightforward process. This guide will walk you through the steps to install Couchbase Server on Ubuntu 22.04 (Jammy Jellyfish) and 20.04 (Focal Fossa).

By following these instructions, you’ll be able to set up your Couchbase instance and begin exploring its capabilities for your data management needs.

Prerequisites

Before you begin the installation, ensure you have:

  • An Ubuntu system running either Ubuntu 22.04 or 20.04.
  • A user account with sudo privileges.
  • A stable internet connection to download packages.

Step-by-Step Installation Process

The most reliable way to install Couchbase Server is by using its official package repository. This ensures you get the latest stable version and makes future updates easy.

1. Add the Couchbase Repository:

First, you need to add the Couchbase APT repository to your system’s sources list. This tells your package manager (apt) where to find the Couchbase packages.

You’ll typically need to download the repository key and add it, then add the repository source list file. The exact commands may vary slightly based on the specific Couchbase version you intend to install, but the general process involves using wget to fetch the key and adding it with sudo apt-key add, followed by adding the repository information to /etc/apt/sources.list.d/. Consult the official Couchbase documentation for the precise repository URL and key download link for the version you require.

A common approach looks something like this (commands are illustrative and depend on the exact repo details):

wget -O couchbase.key <URL_TO_COUCHBASE_KEY>
sudo apt-key add couchbase.key
echo "deb <URL_TO_COUCHBASE_REPO> <UBUNTU_VERSION> couchbase" | sudo tee /etc/apt/sources.list.d/couchbase.list

Replace <URL_TO_COUCHBASE_KEY>, <URL_TO_COUCHBASE_REPO>, and <UBUNTU_VERSION> with the correct details for the Couchbase Server version and your Ubuntu release (e.g., jammy for 22.04 or focal for 20.04).

2. Update Your APT Package Index:

After adding the new repository, you must update your package list so that apt is aware of the new packages available.

Run the following command:

sudo apt update

This command fetches the package information from all configured repositories, including the newly added Couchbase one.

3. Install Couchbase Server:

Now you can install the Couchbase Server package using apt.

Execute the installation command:

sudo apt install couchbase-server

Your system will download and install Couchbase Server and its dependencies. Confirm any prompts to proceed with the installation.

Post-Installation: Initial Setup

Once the installation completes, the Couchbase Server process should start automatically. You can verify its status using:

sudo systemctl status couchbase-server

The key step after installation is configuring your Couchbase cluster via the web administration console.

Accessing the Web Console:

Open a web browser and navigate to the IP address or hostname of your Ubuntu server on port 8091.

For example, if installing on your local machine or accessing from a browser on the same network as the server:

http://<Your-Server-IP-or-Hostname>:8091

You will be greeted by the Couchbase Server setup wizard.

Initial Cluster Configuration:

Through the web console, you will perform the initial setup steps:

  • Set up a new cluster: Choose this option if this is the first node in your cluster.
  • Node Name and IP: Define the name and IP address the node will use.
  • Data and Index Paths: Specify the directories where Couchbase will store data and indexes. Ensure these locations have sufficient space and appropriate permissions.
  • Services: Select which services (Data, Index, Query, Search, Analytics, Eventing) this node will run.
  • Cluster RAM Quotas: Allocate memory for the data and index services.
  • Administrator Account: Create a strong administrator username and password. This is crucial for securing your database.
  • Agreement: Accept the license agreement.

Follow the wizard’s prompts to complete the configuration. Once finished, you’ll be logged into the Couchbase Server administrative dashboard, ready to create buckets, load data, and manage your cluster.

Conclusion

Installing Couchbase Server on Ubuntu 22.04 or 20.04 via the official repository is a reliable and recommended method. By adding the repository, updating your package list, and installing the package, you quickly get the server running. The subsequent steps involve accessing the intuitive web console to perform the vital initial configuration and security setup, including creating your administrator credentials.

With Couchbase Server successfully installed and configured, you’re well on your way to leveraging its powerful NoSQL capabilities for your applications. Remember to secure your installation by setting strong passwords and configuring network access appropriately.
