Apache Couchbase is an open-source, distributed, NoSQL document-oriented database management system. It’s designed to store, manage, and retrieve data in flexible JSON-like documents. Couchbase is suitable for a wide range of use cases, from web and mobile applications to real-time analytics and caching layers. Its combination of performance, scalability, flexibility, and robust features makes it a compelling choice for organizations looking to modernize their data infrastructure.

In this tutorial, we will show you how to install the CouchBase database on Ubuntu 22.04.

Note: Couchbase recommends a server with 4 Cores

Step 1 – Add CouchBase Repository

CouchBase is not included in the Ubuntu default repository by default. Therefore, you will need to add the CouchBase repository to your server.

First, install the required dependencies using the following command:

apt install apt-transport-https ca-certificates software-properties-common -y

Next, download the CouchBase repository package.

curl -O https://packages.couchbase.com/releases/couchbase-release/couchbase-release-1.0-noarch.deb

Next, install the downloaded package file.

dpkg -i couchbase-release-1.0-noarch.deb

Finally, update the repository index using the following command:

apt update

Step 2 – Install CouchBase

You can install the CouchBase server package using the following command:

apt-get install couchbase-server-community

Once the CouchBase is installed, start the CouchBase service and enable it to start at system reboot.

systemctl start couchbase-server
systemctl enable couchbase-server

You can check the status of CouchBase using the following command:

systemctl status couchbase-server

Output:

● couchbase-server.service - Couchbase Server
     Loaded: loaded (/lib/systemd/system/couchbase-server.service; enabled; vendor preset: enabled)
     Active: active (running) since Sat 2024-04-06 03:15:30 UTC; 1min 41s ago
       Docs: https://docs.couchbase.com
   Main PID: 12511 (beam.smp)
      Tasks: 149 (limit: 4579)
     Memory: 224.3M
        CPU: 14.346s
     CGroup: /system.slice/couchbase-server.service

Step 3 – Access CouchBase Web Interface

At this point, the CouchBase server is installed and listens on port 8091. You can check it using the following command:

ss -antpl | grep 8091

Output:

LISTEN 0      128          0.0.0.0:8091       0.0.0.0:*    users:(("beam.smp",pid=12640,fd=53))

Now, open your web browser and access the CouchBase web interface using the URL http://your-IP-address:8091. You will see the CouchBase dashboard on the following screen.

Click on Setup New Cluster. You will see the following screen:

Define your cluster name, admin username, and password, and click on Next. You will see the following screen.

Accept the term and click on Finish with Defaults. You will see the Couchbase dashboard on the following screen.
