Learn how to – How To Install CouchDB on Debian 10 Buster.

Apache CouchDB is an open-source document-oriented NoSQL database written in Erlang with concurrency and fault-tolerance in mind. Its development and releases are under Apache Software Foundation. CouchDB uses JSON to represent data stored in a database. The CouchDB replication allows you to synchronize two or more CouchDB databases. CouchDB RESTful HTTP/JSON API allows you to read, edit, delete and create database documents. In this guide, we will explain how to install CouchDB on Debian 10 Buster.

You need to have SSH access to a server as a user with sudo privileges. Once this is confirmed, access your server via terminal and follow the next steps shared below.

Step 1: Update System

Start by updating all system packages to the latest releases downloadable on the server.

sudo apt update
sudo apt -y upgrade

Step 2: Install Dependecies

Install all required dependencies to build CouchDB on Debian 10 Buster.

sudo apt update
sudo apt-get --no-install-recommends -y install build-essential pkg-config erlang libicu-dev libmozjs185-dev libcurl4-openssl-dev

Step 3: Create couchdb user for CouchDB

Create a couchdb system user to run CouchDB service.

sudo adduser --system 
        --shell /bin/bash 
        --group --gecos 
        "CouchDB Administrator" couchdb

Step 4: Build CouchDB on Debian 10 Buster

Download the latest stable release of CouchDB database archive.

curl -s https://api.github.com/repos/apache/couchdb/releases/latest 
  | grep browser_download_url 
  | cut -d '"' -f 4 
  | wget -qi -

Run the command below to build CouchDB on Debian 10 (Buster).

$ tar xvf apache-couchdb-*.tar.gz
$ cd apache-couchdb-*/
$ ./configure

To build CouchDB you should run:

$ make release

Try gmake if make is giving you any problems. If everything was successful you should see the following message:

Installing CouchDB into rel/couchdb/ ...
==> rel (generate)
WARN:  'generate' command does not apply to directory /root/apache-couchdb-2.3.1
... done

    You can now copy the rel/couchdb directory anywhere on your system.
    Start CouchDB with ./bin/couchdb from within that directory.

To install CouchDB into your system, copy the rel/couchdb to your desired installation location.

sudo cp -r rel/couchdb /home/couchdb
sudo chown -R couchdb:couchdb /home/couchdb/

List directory contents:

$ ls -1 /home/couchdb/couchdb/
bin
erts-10.2.4
etc
lib
LICENSE
releases
share
var

Change the permission of the CouchDB directories by running:

find /home/couchdb -type d -exec chmod 0770 {} ;
chmod 0644 /home/couchdb/couchdb/etc/*

Step 5: Configure CouchDB Systemd Service

We need to create a coucdb systemd service for managing application status.

sudo tee /etc/systemd/system/couchdb.service<<EOF
[Unit]
Description=Couchdb service
After=network.target

[Service]
Type=simple
User=couchdb
ExecStart=/home/couchdb/couchdb/bin/couchdb -o /dev/stdout -e /dev/stderr
Restart=always

[Install]
WantedBy=multi-user.target
EOF

Reload systemd daemon.

sudo systemctl daemon-reload
sudo systemctl start couchdb.service
sudo systemctl enable couchdb.service

Confirm service status

$ systemctl  status couchdb.service
● couchdb.service - Couchdb service
   Loaded: loaded (/etc/systemd/system/couchdb.service; disabled; vendor preset: enabled)

Make sure CouchDB is still running, and then do:

$ curl http://127.0.0.1:5984/
{"couchdb":"Welcome","version":"2.3.1","git_sha":"c298091a4","uuid":"cf6f7c87e049c287e1459a53c8415c39","features":["pluggable-storage-engines","scheduler"],"vendor":{"name":"The Apache Software Foundation"}}

This issues a GET request to your newly installed CouchDB instance.

Test database creation:

$ curl -X PUT http://127.0.0.1:5984/testdb
{"ok":true}

$  curl -X PUT http://127.0.0.1:5984/testdb1
{"ok":true}

$  curl -X PUT http://127.0.0.1:5984/testdb2
{"ok":true}

$ curl -X GET http://127.0.0.1:5984/_all_dbs
["testdb","testdb1","testdb2"]
