I've used these Install Instructions for CouchDB 2.1.1 on a DigitalOcean Droplet running Ubuntu 16.04

ssh root@Droplet-IP-ADDRESS
root@ubuntu-droplet:~# cd ../home
root@ubuntu-droplet:/home# mkdir temp

root@ubuntu-droplet:/home# cd temp

Copy and paste the "install-couchdb.sh" script included below to a file in the "/home/temp" directory and name it "install-couchdb.sh"

root@ubuntu-droplet:/home/temp# nano install-couchdb.sh

Then change the permissions and run the script:

root@ubuntu-droplet:/home/temp# chmod 777 install-couchdb.sh

Run the script to install CouchDB

root@ubuntu-droplet:/home/temp# ./install-couchdb.sh

After install:

root@ubuntu-droplet:/home/couchdb# curl http://localhost:5984

Output should be something like: {"couchdb":"Welcome","version":"2.1.1","features":["scheduler"],"vendor":{"name":"The Apache Software Foundation"}} Edit local ini file to bind ip address:

root@ubuntu-droplet:/home/couchdb# nano etc/local.ini

restart the server sudo reboot

root@ubuntu-droplet:~# curl http://IP ADDRESS:5984

Output should be something like: {"couchdb":"Welcome","version":"2.1.1","features":["scheduler"],"vendor":{"name":"The Apache Software Foundation"}} The script below is an updated version of the one found here: https://github.com/afiskon/install-couchdb/blob/master/install-couchdb.sh ####### install-couchdb.sh Script !/bin/sh
