Apache CouchDB, a powerful open-source NoSQL database server, can easily be installed on Ubuntu 16.04 / 17.10 and 18.04. This tutorial will show students and new users how to do that.
Here’s a brief overview for those who don’t know Apache CouchDB.
Apache CouchDB is a general-purpose NoSQL database server that works just like any other database behind an application server of your choice.
You can add custom functions using different programming languages such as Erlang, C/C++, Java, etc. In addition, it uses JSON natively and supports binaries for all your data storage needs.
It is used by major corporations and businesses looking for high-performance NoSQL database systems. Most people will tell you a thing or two about MySQL and MariaDB. However, for professionals, Apache CouchDB is a stable choice.
To learn how to install Apache CouchDB Ubuntu, follow the steps below
Add Apache CouchDB Repository to Ubuntu
Adding the Apache CouchDB repository to Ubuntu is easy. All you have to run is run the commands below to add the repository key. The key is there to authenticate and validate packages from the repository.
Run the commands below to add the repository key and the repository.
sudo apt install curl curl -L https://couchdb.apache.org/repo/bintray-pubkey.asc \ | sudo apt-key add - echo "deb https://apache.bintray.com/couchdb-deb xenial main" \ | sudo tee -a /etc/apt/sources.list.d/apache_couchdb_xenial.list echo "deb https://apache.bintray.com/couchdb-deb bionic main" \ | sudo tee -a /etc/apt/sources.list.d/apache_couchdb_bionic.list
When you’re done, continue below.
Update and Install Apache CouchDB

During the installation, you should see messages to select some options.
┌──────────────────────────┤ Configuring couchdb ├──────────────────────────┐
│ │
│ Please select the CouchDB server configuration type that best meets your
│ needs.
│
│ For single-server configurations, select standalone mode. This will set
│ up CouchDB to run as a single server.
│
│ For clustered configuration, select clustered mode. This will prompt for
│ additional parameters required to configure CouchDB in a clustered
│ configuration.
│
│ If you prefer to configure CouchDB yourself, select none. You will then
│ need to edit /opt/couchdb/etc/vm.args and /opt/couchdb/etc/local.d/*.ini
│ yourself. Be aware that this will bypass *all* configuration steps,
│ including setup of a CouchDB admin user - leaving CouchDB in "admin

Next, select a standalone option and continue.

After that, type and confirm the admin password and complete the installation. After installing Apache CouchDB, the commands below can be used to stop, start, enable, and check its status.
sudo systemctl stop couchdb.service sudo systemctl start couchdb.service sudo systemctl enable couchdb.service sudo systemctl status couchdb.service
This is what the status command shows

i want to know how to configure cluster on couchdb 2.2, how to add node?
can i get some tutorial?
when run ‘ sudo systemctl status couchdb.service ‘ I receive everything as shown in your example in my Unbuntu 18.04 environment. When I navigate to the url: http://127.0.0.1:5984/_utils/, I received page not found. I noticed that from my machine when I do ‘telnet 127.0.0.1 5984’ I am not connecting. Also how do you return to the powershell prompt after running ‘sudo systemctl status couchdb.service’?
After setting up couchdb and running the status command, I am receiving the following:
kelalfbry@BRYANTVM:~$ sudo systemctl status couchdb.service
