sudo dnf install yum-utils -y

Then, enable CRB (PowerTools) and Epel repo with the following commands:

sudo dnf config-manager --set-enabled crb
sudo dnf install epel-release -y

Now use the following command to enable the CouchDB repo on RHEL 9:

sudo dnf config-manager --add-repo https://couchdb.apache.org/repo/couchdb.repo

Step 2 – Install ApacheCouchDB on RHEL 9

Once you added your package repository, you can use the following commands to install CouchDB on your RHEL 9:

# sudo dnf update -y
# sudo dnf install mozjs78 -y
# sudo dnf install couchdb -y

Step 3 – Start and Enable Apache CouchDB Service

Once your installation is completed, you need to start and enable CouchDB on RHEL 9 by using the commands below:

# sudo systemctl start couchdb
# sudo systemctl enable couchdb

Then, verify your CouchDB service is active and running:

sudo systemctl status couchdb

Step 4 – CouchDB Configuration on RHEL 9

In this step, we want to configure CouchDB in a Standalone mode. It is a single-mode configuration. To do this, open the CouchDB config file with your desired text editor like Vi editor or Nano Editor:

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

In the file, look for the [chttpd] section. Then, uncomment the port and bind_address directives.

Note: The default value for standalone mode is 127.0.0.1. You can change it to 0.0.0.0 which listens to all interfaces. Or, you can change it to a specific IP address.

[chttpd]
port = 5984
bind_address = 127.0.0.1

Next, find the [admins] section. From there, uncomment the admin directive and set a password for the admin user.

[admins]
admin = mypassword

When you are done, save and close the file.

Restart your CouchDB service on RHEL 9 to apply the changes:

sudo systemctl restart couchdb

Step 5 – Configure Firewall Rules for Apache CouchDB

At this point, you must allow CouchDB port 5984 through your firewall rules. To do this, you can run the following command:

sudo firewall-cmd --zone=public --permanent --add-port=5984/tcp

To apply the new rules, reload the firewall:

sudo firewall-cmd --reload

Or from your web browser, you can follow the URL below:

http://server-ip:5984/_utils/

You will see the CouchDB login screen. Enter the Admin credentials you have defined in the configuration step and click Log in.

Then, you will see your CouchDB database dashboard.
