- - all of the following commands should be performed creating a python file with fabric libraries to do - -it automatically
- - after the creation of the instance and the volume. We need to attach the volume to its instance.
- - to see if the disk is attached
sudo fdisk -l
- - format disk
sudo mkfs.ext4 /dev/vdc

- -create a folder to manually mount the disk
sudo mkdir /mnt/data

- -mount the disc
sudo mount /dev/vdc /mnt/data

- -give permission to ubutntu user to save in the disk
sudo chown -R ubuntu /mnt/data

- -modify /etc/fstab in order to mount the disk automaticlly when it reboots
sudo vi /etc/fstab

- -add this line at the end of the file
/dev/vdc        /mnt/data       auto    defaults        0       1


- -create a folder to install CouchDB database
sudo mkdir /mnt/data/couchdb

- -reboot the instance
sudo reboot

- -update apt
sudo apt-get update

- -finally installing couchdb
sudo apt-get install couchdb -y

- -install curl:
sudo apt-get install curl

- -test couchdb
curl localhost:5984

- -give CouchDB permissions to read and write in the folder that is located in the volume
sudo chown -R couchdb:couchdb /mnt/data/couchdb/

- -backup default.ini (just in case that we need, it is not necesary)

cd /etc/couchdb
sudo cp default.ini default.ini.back

- -open the port to acces FUTON in default.ini
- -it seems like this:
- -    [couchdb]
- -    ;database_dir = /var/lib/couchdb
- -    ;view_index_dir = /var/lib/couchdb
- -    database_dir = /mnt/data/couchdb
