Setup Ruby on Rails in DigitalOcean

Recently I moved the site from Heroku to DigitalOcean. As you can imagine, deployment could be difficult. Therefore I’d like to summarise the steps to deploy to DigitalOcean.

Create a droplet with one-click Ruby on Rails Application

First of all, you need to create a droplet in DigitalOcean.

Install git

SSH to the server then run

sudo apt-get install git-core

Configurate codebase

git clone <repo_https>
chmod 755 rails
chown -R rails:www-data <repo>

Deploy

1. Configure the database to point to the database

2. Install gems bundle install --deployment

3. Add any environmental variables to /etc/default/unicorn

4. Restart the server service unicorn restart

5. Allow remote access to the DB

   sudo nano /etc/mysql/my.cnf
   bind-address = your_database_IP
   GRANT ALL PRIVILEGES ON db.* To 'user'@'%' IDENTIFIED BY 'password';
   FLUSH PRIVILEGES;
