Prepare to install rbenv

$ sudo yum install git
$ sudo yum -y install gcc
$ sudo yum -y install gcc-c++
$ sudo yum -y install zlib-devel
$ sudo yum -y install openssl-devel
$ sudo yum -y install readline-devel

Install rbenv

$ mkdir ~/.rbenv
$ git clone https://github.com/rbenv/rbenv.git ~/.rbenv
$ mkdir ~/.rbenv/plugins ~/.rbenv/plugins/ruby-build
$ git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
$ cd ~/.rbenv/plugins/ruby-build
$ sudo ./install.sh
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
$ echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
$ source ~/.bash_profile

Install Ruby

$ rbenv install 2.4.6
$ rbenv rehash
$ rbenv global 2.4.6
$ ruby -v

Install Bundler

$ rbenv exec gem install bundler -v 2.0.1
$ rbenv rehash

Create a project on GitHub

Push to GitHub

On Mac
$ git remote add origin <URL Address>                    
$ git add .                                          
$ git commit -m "1st push"                           
$ git push -u origin master                          

Pull from GitHub to EC2

$ git clone <URL Address>
$ cd <The project's directory>                       

Install Rails

$ gem i -v 5.2.3 rails
$ gem list rails                     

$ bundle install                   

The below command executed due to an error occurred.

$ gem install pg -v '1.1.4' --source 'https://rubygems.org/'

Install postgreSQL

$ yum install postgresql
$ sudo yum install postgresql-devel                   

To avoid the SQLite3's error

$ sudo yum install sqlite-devel                    

Configure instance's security group inbound

• Configure Custom TCP/IP port　3000 0.0.0.0/0 additionally.

Start PostgreSQL on the EC2 instance

$ sudo yum install -y postgresql-server
$ sudo /sbin/service postgresql initdb
$ sudo /sbin/service postgresql start                    

Configure PostgreSQL on the EC2 instance

Master username：<the project's name>
Master password：<password>
postgres=# create role <username> with createdb login password '<password>';
postgres=# create database [database_name] owner [user_name];

$ sudo -u postgres psql
postgres=# create role <The project's name> with createdb login password '<password>';
postgres=# create database <the project's name>_production owner <The project's name>;
postgres=# create database <the project's name>_development owner <the project's name>;
postgres=# create database <the project's name>_test owner <the project's name>;
postgres=# \q                 

Create DB（Postgres）

.bash_profile
export POSTGRES_USERNAME="<The project's name>"
export POSTGRES_PASSWORD="<Password>"

The project's directory
$ rails db:create                     

 /var/lib/pgsql9/data/pg_hba.conf

local all all peer

　　　　　↓

local all all md5

Modified                     

$ rails db:create
$ rails db:migrate                    

Configure SMTP

Configure the environment variable in .bash_profile.

EMAIL_ADDRESS
EMAIL_PASSWORD

After that, execute the below command to reflect it.

$ source .bash_profile                     

• Launch Redis server on EC2.
• Select ElasticCache.
• Press 'Create'.

Primary endpoint generated.

Select 'security group' for Redis's inbound configuration on VPC configuration.

• Add it on the inbound edition of sg-694f3715.
• Custom TCP：TCP
• port：6379
• source 0.0.0.0/0

Configure the below files

config/initializers/sidekiq.rb
config/redis.yml                    

Restart the project and start Sidekiq

$ bundle exec sidekiq                      

Install Nginx

$ sudo yum install nginx

Copy /usr/local/etc/nginx/nginx.conf which is on Mac to EC2

$ scp -i ~/.ssh/<The project name名> nginx.conf [e-mail]:~/nginx.conf
$ sudo cp ~/nginx.conf /etc/nginx/

Modify the port number and root directory.

Start Unicorn

$ unicorn -c config/unicorn.rb -E production -D                      

Start Nginx

$ sudo service nginx start                     

Add port80(HTTP) for VPS configuration.

Modify the permission of the home directory to 744(drwxr--r--)

$ chmod 755 ~/                     

Restart Nginx

$ sudo service nginx restart

Create DB on the production environment

$ rails db:migrate RAILS_ENV=production                      

Restart Unicorn

$ kill [pid]
$ unicorn -c config/unicorn.rb -E production -D
