What is this?

This is an automated script to help you setup new server and deploy Rails application along with database dump.

Requirements:

Ubuntu 16.04 or newer

Preparation

1. Execute within your rails app directory: git clone [email protected]:Freika/rails_server.git server
2. Create file server/hosts and set values as shown in an example below. User and database passwords should be encrypted.
3. Place your postgres database dump at server/app_name.sql. Dump must be created with following command: pg_dump --no-owner app_name > app_name.sql -U DB_USERNAME
4. Update IP address of your server in config/deploy/production.rb and set user value to deploy.
5. Install roles from ansible-galaxy:

ansible-galaxy install -r server/requirements.yml

hosts file

Create file hosts in root directory of ansible script. Here is an example:

[rails]
# Your server IP address
IP_ADDRESS

[rails:vars]
# Your application name
app_name=APP_NAME
# Your app domain (for nginx configuration)
app_domain=example.com
# Password for user deploy, encrypted in md5
user_password=PASSWORD

# Enable or disable monit installation
monit_enabled=true
# Username for monit
monit_user=MONIT_USERNAME
# Password for monit, plain text
monit_password=MONIT_PASSWORD
# Allowed IP for monit sign in
monit_allowed_ip=0.0.0.0

# Ruby version
ruby_version=2.3.3

# Make it false for fresh deploy
restore_backup=true
# Your app database password (for database.yml)
postgres_password=00000000

backup_to_aws=true
aws_key=AWS_KEY
aws_key_secret=AWS_SECRET_KEY
aws_region=eu-west-1
aws_bucket_name=YOUR_BUCKET_NAME

slack_webhook_url=https://hooks.slack.com/services/SOME_GENERATED_VALUE

# For local testing
;ansible_ssh_user=vagrant
;ansible_ssh_private_key_file=~/.vagrant.d/insecure_private_key

IMPORTANT After first deploy and restore database from backup don't forget to change restore_backup value to false. In other case on next applying app.yml playbook your database will be rewrited with provided in server directory.

Usage

Server

Run

ansible-playbook server/python.yml server/server.yml
cap production deploy:check
ansible-playbook server/app.yml -i server/hosts

This script goes through full server configuration process. For now it does next things (in order of applying):

python.yml

• Installs Python2 in order to allow Ansible do all the work
• Installs pip, python packet manager

server.yml

• Creates deploy user which is our main user for application deployments
• Configures zsh and oh-my-zsh for both root and deploy users
• Installs vim and htop
• Installs monit for server state monitoring and notifications (RAM, HDD, etc)
• Installs nginx with passenger to serve your Rails applications
• Installs Redis
• Installs Ruby
• Installs PostgreSQL

app.yml

• Configures Nginx to server your Rails application
• Creates PostgreSQL database and user for your Rails application
• Uploads database dump and restores it on server
• Setups daily DB backups with uploading to Yandex Disk

Application

Run cap production deploy to start deployment process.

That's all!

Deploying application to already configured server

Just run ansible-playbook server/app.yml -i server/hosts. You'll also want to update files from Preparation as appropriate.

Local testing

Install Vagrant, run vagrant up and then provision it as if it's just your production server.
