Deploy Rails without Capistrano and anger

BLAh blah not finished article yet.

First think which you need to know — you don’t have to use Capistrano for deploy your ruby on rails web application.

1. Setting ubuntu

WARNING: DON”T USE UBUNTU up than 18.04 yet. Because Passenger.

$ adduser deploy
$ adduser deploy sudo #add user to sudo group
$ cd .. && cd /home/deploy
$ mkdir .ssh
$ ssh-keygen -t rsa -C 'enotikalt@gmail.com'

STOP COPYING!!!!

when shh program will ask you about place of file — past this:

/home/deploy/.ssh/id_rsa

Generate ssh on server and add public ssh key from your local computer to file /home/someuser/.ssh/authorized_keys on a server.

install nodejs, yarn, redis-server etc

# Adding Node.js repository
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
# Adding Yarn repo
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo add-apt-repository ppa:chris-lea/redis-server
# Refresh our packages list with the new repositories
sudo apt-get update
# Install our dependencies for compiiling Ruby along with Node.js and Yarn
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev software-properties-common libffi-dev dirmngr gnupg apt-transport-https ca-certificates redis-server redis-tools nodejs yarn

RBENV is sucks. Let’s install rvm

$ gpg --keyserver hkp://pool.sks-keyservers.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
$ \curl -sSL https://get.rvm.io | bash

CREATE Gemset. Gemset is a folder inside RVM (like box). In this place you can install gems, but in the future, when you will want to update your rails application for newest rails version — you can just create new gemset (box with gems lol). If something went wrong — just change CURRENT gemset and it will works again.

Check your bundler gem version on local machine and install it in gemset on server

$ bundle info bundler 

server

$ gem install bundler -v 3.3.3.3.3

2. Passenger

INSTALL PASSENGER

passenger it’s a program which knows how to work with ruby projects. It works after nginx get request

# Install our PGP key and add HTTPS support for APT
$ sudo apt-get install -y dirmngr gnupg
$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 561F9B9CAC40B2F7
$ sudo apt-get install -y apt-transport-https ca-certificates
# Add our APT repository
sudo sh -c 'echo deb https://oss-binaries.phusionpassenger.com/apt/passenger bionic main > /etc/apt/sources.list.d/passenger.list'
sudo apt-get update
# Install Passenger + Nginx module
sudo apt-get install -y libnginx-mod-http-passenger

enable the Passenger Nginx module and restart Nginx

$ if [ ! -f /etc/nginx/modules-enabled/50-mod-http-passenger.conf ]; then sudo ln -s /usr/share/nginx/modules-available/mod-http-passenger.load /etc/nginx/modules-enabled/50-mod-http-passenger.conf ; fi
$ sudo ls /etc/nginx/conf.d/mod-http-passenger.conf

If you don’t see a file at /etc/nginx/conf.d/mod-http-passenger.conf; then you need to create it yourself and set the passenger_ruby and passenger_root config options. For example:

passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
passenger_ruby /usr/bin/passenger_free_ruby;#REWRITE THIS LINE TO:->
passenger_ruby /home/deploy/.rvm/wrappers/ruby-3.0.0@r6131/ruby;

—

$ sudo service nginx restart

YAY!

3. NGINX, DATABASE, ENVIRONMENT VARIABLES

connect to server

clone your your project from github

git clone git://github.com/username/myapp.git

WARNING : REMEMBER NAME OF THIS FOLDER

sudo rm /etc/nginx/sites-enabled/default

sudo vim /etc/nginx/sites-enabled/myapp

server {
  listen 80;
  listen [::]:80;

  server_name 1.2.3.4; #this is yout ip or domain name
  root /home/deploy/myapp/public;

  passenger_enabled on;
  passenger_app_env production;

  location /cable {
    passenger_app_group_name myapp_websocket;
    passenger_force_max_concurrent_requests_per_process 0;
  }

  # Allow uploads up to 100MB in size
  client_max_body_size 100m;

  location ~ ^/(assets|packs) {
    expires max;
    gzip_static on;
  }
}

$ sudo service nginx reload

$ sudo apt-get install postgresql postgresql-contrib libpq-dev

$ sudo -u postgres psql

psql#> create role deploy with createdb login password ‘qwerty’;
$ psql -d postgres -U myuser # myuser == created role inside postgres before

It will login you to user which we was create inside postgresql

> create database myapp_production;

export DATABASE_URL=postgresql://deploy:juice@127.0.0.1/myapp_production
export RAILS_MASTER_KEY=bla2bla3
export RAILS_SECRET_KEY_BASE=keyFrom_rails_credentialsEdit
export REDIS_URL=redis://127.0.0.1:6379/1
export RAILS_ENV=production
export REDIS_SIDEKIQ_DB=0
# For Postgres
export DATABASE_URL=postgresql://deploy:PASSWORD@127.0.0.1/myapp

# For MySQL
export DATABASE_URL=mysql2://deploy:$omeFancyPassword123@localhost/myapp

export RAILS_MASTER_KEY=ohai
export SECRET_KEY_BASE=1234567890

STRIPE_PUBLIC_KEY=x
STRIPE_PRIVATE_KEY=y

thats all, your app is works now. Check your ip via browser
