Install and run Ruby on Rails on Windows10

It seems ruby needs Unix env in some points. So in windows, we should use wsl to run ruby.

Enable Windows subsystem for Linux and install Linux

I guess this site has explained very clear. Don’t forget to sudo apt update and upgrade.

Install Ruby/ Ruby On Rails on Windows

Open cmd and type “bash” to turn on wsl.

Then follow all the command line:

    4  sudo apt update
    5  sudo apt upgrade
    8  sudo apt install build-essential
    9  sudo apt install git-core curl
   10  sudo apt install libssl-dev libyaml-dev
   11  sudo apt install libreadline-dev libxml2-dev
   12  sudo apt install libsqlite3-dev sqlite3 libffi-dev
   20  explorer.exe .
   22  sudo apt install zlib1g-dev libxslt1-dev libcurl4-openssl-dev
   23  sudo apt install software-properties-common
   24  curl -fsSL | bash

   25  nano .bashrc
   27  source .bashrc
   28  which rbenv

   29  rbenv install --list
   30  rbenv install 2.7.3

   32  rbenv versions
   33  rbenv global 2.7.3
   34  rbenv versions
   35  ruby -v
   36  gem -v
   37  gem list
   38  gem install rails
   39  rbenv rehash
   40  rails -v
   41  history > print.txt

I have deleted some irrelevant command lines and leave all needed lines. Before line 24, all sudo commands are just installed with all the needed packages.

[Action needed] From line 25 to 28, is going to add the “rbenv” PATH. After opening the .bashrc file, navigate to the end of the file and add 2 lines as below:

export PATH="$HOME/ .rbenv/bin:$PATH"
eval "$(rbenv init -)"

The first line is to set PATH to find the rbenv. And the second line is to tell Linux when it launched go ahead and get ready for the rbenv. After typed these 2 lines, hit “Ctrl + X” and “y” then confirm the file name (no change) by press enter.

source .bashrc is to re-run the file again instead of reboot wsl.

which rbenv is to confirm if the PATH is set or not.

Install MySQL

Use sudo the install MySQL:

sudo apt install mysql-server mysql-client libmysqlclient-dev  

Then type “sudo service mysql status” to confirm the installation. If the MySQL is stopped, type “sudo service mysql start” to start it.

Next, we should secure our mysql by the command:

sudo mysql_secure_installation

It would prompt pop a couple questions, except the first question (password validate), all answer “y”.

OK…so the next step is a bit tricky since there is a bug in MySQL. If you tried to use “mysql -u root -p” then enter the password you just made, it won’t work.

We will need to change the config by enter “sudo mysql -u root” then enter typing your sudo password, enter “USE mysql;” Then select data from the user table. “SELECT User, host, plugin FROM user;”

You can see the plugin scheme for the root user is auth_socket

Next, change the root user plugin by the follow query:

UPDATE user SET plugin='mysql_native_password' WHERE user='root';

Then make sure the change has executed by “SELECT User, host, plugin FROM user;”

change has been implemeted

Finally enter “FLUSH PRIVILEGES;” to let the change effect. Then “quit;” mysql to the Ubuntu and enter “mysql -u root -p” try the mysql password again to see if you can log in.

Install MySQL Ruby gems on Windows

gem install mysql2

Install JavaScript tools for Ruby on Rails

We will need to install node.js, Yarn. Just enter all the command lines as below:

   18  gem install mysql2
   20  curl -sL | sudo -E bash -
   21  sudo apt-get install -y nodejs
   22  sudo apt install gcc g++ make
   23  curl -sL | sudo apt-key add -
   24  echo "deb stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
   25  sudo apt-get update && sudo apt-get install yarn

Use the webserver on Windows

The common webservers are “Apache 2”, “NGINX (engine-X)” or some minor ones “Passenger”, “Unicorn”, “Puma”. Since Ruby on Rails already build-in with Puma, so for local testing, we are using Puma.

Go to your target folder and simply type “rails new your_project_name -d mysql”
