After this, it is necessary to configure the network interface of the CouchDB node. In the image are the instructions, however, it is recommended 0.0.0.0.0 for you to be able to access from all networks.
Finally, set a password for admin user.
Next, start and enable the service.

Finally, open your web browser and go to http://YOUR_IP:5984/_utils and access the web interface to manage the program.
And that’s it.
