Apache CouchDB is an open-source NoSQL database server that uses a schema-free document model to store data. It is designed for reliability and simplicity, making it ideal for web and mobile applications. In this guide, we will show you how to install Apache CouchDB on Debian 11.

Step 1: Update Your System

Start by updating your system to ensure all packages are up-to-date:

sudo apt update && sudo apt upgrade

Step 2: Add the CouchDB Repository

Next, add the official Apache CouchDB repository to your system. Run the following commands:

sudo apt install curl gnupg
curl https://couchdb.apache.org/repo/bintray-pubkey.asc | sudo apt-key add -
echo "deb https://apache.bintray.com/couchdb-deb/ focal main" | sudo tee -a /etc/apt/sources.list

Update your package list again:

sudo apt update

Step 3: Install CouchDB

Now, install Apache CouchDB by running the following command:

sudo apt install couchdb

Step 4: Configure CouchDB

During the installation, you will be asked to choose the CouchDB configuration mode. You can choose "Standalone" for a single-server setup. You will also be prompted to enter the IP address for the server, as well as an administrator username and password.

If you missed any configuration steps, you can manually configure CouchDB by editing the /opt/couchdb/etc/local.ini file:

sudo nano /opt/couchdb/etc/local.ini

Step 5: Start and Enable CouchDB

Once CouchDB is installed, start the CouchDB service and enable it to start on boot:

sudo systemctl start couchdb
sudo systemctl enable couchdb

Step 6: Access CouchDB Web Interface

By default, CouchDB runs on port 5984. You can access the CouchDB web interface, Futon, by navigating to http://your_server_ip:5984/_utils/ in your web browser. Use the credentials you set during installation to log in.

Step 7: Secure CouchDB with SSL

It is recommended to secure CouchDB with SSL, especially in production environments. You can configure SSL in the /opt/couchdb/etc/local.ini file by specifying the paths to your SSL certificate and key:

[ssl]
enable = true
cert_file = /path/to/your/certificate.crt
key_file = /path/to/your/private.key

After configuring SSL, restart the CouchDB service:

sudo systemctl restart couchdb
