Create Rails Application

Install MariaDB

Use Ubuntu Repository

• Run:

sudo apt update

• Run:

sudo apt install -y mariadb-server mariadb-client

• Run:

sudo apt install -y libmariadb-dev

Use mysql secure installation

• Run:

sudo mysql_secure_installation

In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and haven't set the root password yet, you should just press enter here. Enter current password for root (enter for none): << Just Press Enter OK, successfully used password, moving on... Change the root password? [Y/n] Y << Set MariaDB root password New password: **<< Enter New Psssword Re-enter new password: *** << Re-Enter New Password Password updated successfully! Reloading privilege tables.. ... Success! By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] Y << Remove Anonymous Users ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] Y << Disallow root login remotely ... Success! By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] Y << Remove test database -Dropping test database... ... Success! -Removing privileges on test database... ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] Y << Reload Tables ... Success! Cleaning up... All done! If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB!

Log into MariaDB as root user

• Run:

sudo mysql -u root -p

Use root password you created in mysql_secure_installation.

Enter, use mysql;

Than enter, update user set plugin='mysql_native_password' where user='root';

Next enter, flush privileges;

Lastly enter, quit;

Create a Database

Create Database User Login as root

• Run:

sudo mysql -u root -p

Enter, CREATE USER 'user'@'localhost' IDENTIFIED BY 'password' ;

Next enter, GRANT ALL PRIVILEGES ON . TO 'user'@'localhost' ;

Than enter, exit

Use the user you are logged in under.

Install the mysql2 extension

• Run:

gem install mysql2

Create Rails Application

• Run:

cd ~

• Run:

rails new myapp -d mysql

You can name your new myapp whatever you want.

• Run:

cd myapp

Update configuration file with the database information.

• Run

sudo vi config/database.yml

Enter DB user details shown like below.

default: &default

adapter: mysql2

encoding: utf8mb4

pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %> username: root << DB User

password: **** << DB Password

socket: /var/run/mysqld/mysqld.sock

Create the Database

• Run:
