Steps to build a Ruby on Rails development environment with Vagrant

environment

macOS 10.15.4

Install Vagrant

Install Vagrant from your home page.

Install Cent OS

First, check if Vagrant is installed.

terminal

$ vagrant -v
Vagrant 2.2.9

Create a directory and move it.

terminal

$ mkdir -p vagrant/centos7
$ cd vagrant
$ cd centos7

Execute the following command in the moved directory.

terminal

$ vagrant init centos/7

After the installation is complete, open an editor and uncomment the line below.

Vagrantfile

# config.vm.network "private_network", ip: "192.168.33.10"

Run the command below and wait a moment ...

terminal

$ vagrant up

Log in to CentOS

Execute the following command to log in.

terminal

$ vagrant ssh
[vagrant@localhost ~]$  

Install rbenv

Prepare the yum package.

terminal

$ sudo yum install -y git gcc openssl-devel readline-devel zlib-devel sqlite-devel gcc-c++ libicu-devel cmake vim

Install rbenv.

terminal

$ git clone https://github.com/sstephenson/rbenv.git ~/.rbenv    
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
$ echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
$ source ~/.bash_profile

Check if the installation is complete.

terminal

$ rbenv --version
rbenv 1.1.2-30-gc879cb0

Added ruby-build plugin

Execute the following command to add the ruby-build plugin.

terminal

$ git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build

Install Ruby

Install Ruby.

• As an aside, the version was 2.4 when I referred to another person's site. However, Rails 5 or higher and the current mainstream Rails version require 2.5 or higher, so please be careful about version specification etc.

terminal

$ rbenv install 2.7.1
$ rbenv global 2.7.1
$ rbenv rehash
$ ruby -v 

After confirming that the installation is complete, proceed to the next step.

Install Bundler

Execute the following command to install Bundler.

terminal

$ gem install bundler
$ rbenv rehash
$ bundle -v
Bundler version 2.1.4

Install Ruby on Rails

Create and move the directory for installation.

terminal

$ mkdir -p app/memo_app
$ cd app
$ cd memo_app

Then run the command to install.

terminal

$ bundle init
$ sed -i 's/# gem "rails"/gem "rails", "~> 5.1.0"/g' Gemfile
$ bundle install --path vendor/bundler
$ bundle exec rails new .
$ sed -i "s/# gem 'therubyracer'/gem 'therubyracer'/g" Gemfile
$ bundle install

Start the server

Execute the following command to access the following address.

terminal

$ ./bin/rails s -b 0.0.0.0

http://192.168.33.10:3000/

This is the end of the procedure ^ _ ^

(Supplement) About shutdown and login / logout

I will also explain shutdown and login / logout because you will need it when you close it once or reopen it.

** Log out **

terminal

#Command for logging out of CentOS
$ exit
 
#Command to shut down CentOS
$ vagrant halt
   

** Login **

terminal

#Commands for logging in to Cent OS
$ vagrant up
   
$ vagrant ssh
[vagrant@localhost ~]$

Procedure to enable you to create an application with a high-performance editor (VS Code) even in the Vagrant development environment

A virtual environment of Vagrant has been built, but please also refer to it because it explains how to connect it so that it can be created and edited even with a high-performance editor (VSCode) ^ _ ^
