			=Final Steps=

			#### If you want to use SQLite (not recommended)
			rails new myapp

			#### If you want to use MySQL
			rails new myapp -d mysql

			#### If you want to use Postgres
			# Note that this will expect a postgres user with the same username
			# as your app, you may need to edit config/database.yml to match the
			# user you created earlier
			rails new myapp -d postgresql

			# Move into the application directory
			cd myapp

			# If you setup MySQL or Postgres with a username/password, modify the
			# config/database.yml file to contain the username/password that you specified

			# Create the database
			rake db:create

			rails server


			You can now visit http://localhost:3000 to view your new website!

			Now that you've got your machine setup, it's time to start building some Rails applications.


			If you received an error that said ''Access denied for user 'root'@'localhost' (using password: NO)'' then you need to update your '''config/database.yml''' file to match the database username and password.

			=Setting Up PostgreSQL=

			For PostgreSQL, we're going to add a new repository to easily install a recent version of Postgres.

			sudo apt install postgresql-11 libpq-dev


			The postgres installation doesn't setup a user for you, so you'll need to follow these steps to create a user with permission to create databases. Feel free to replace ''chris'' with your username.

			sudo -u postgres createuser chris -s

			# If you would like to set a password for the user, you can do the following
			sudo -u postgres psql
			postgres=# \password chris

	rbenv users need to run '''rbenv rehash''' after installing bundler.		rbenv users need to run '''rbenv rehash''' after installing bundler.


			== Using rvm==

			The installation for '''rvm''' is pretty simple:

			sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev
			gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
			curl -sSL https://get.rvm.io \| bash -s stable
			source ~/.rvm/scripts/rvm
			rvm install 2.7.0
			rvm use 2.7.0 --default
			ruby -v


			==From source==

			Arguably the least useful Ruby setup for development is installing from source, but I thought I'd give you the steps anyways:

			cd
			wget http://ftp.ruby-lang.org/pub/ruby/2.7/ruby-2.7.0.tar.gz
			tar -xzvf ruby-2.7.0.tar.gz
			cd ruby-2.7.0/
			./configure
			make
			sudo make install
			ruby -v



			=Configuring Git=

			We'll be using Git for our version control system so we're going to set it up to match our Github account. If you don't already have a Github account, make sure to register. It will come in handy for the future.


			Replace my name and email address in the following steps with the ones you used for your Github account.


			git config --global color.ui true
			git config --global user.name "YOUR NAME"
			git config --global user.email "YOUR@EMAIL.com"
			ssh-keygen -t rsa -b 4096 -C "YOUR@EMAIL.com"


			The next step is to take the newly generated SSH key and add it to your Github account. You want to copy and paste the output of the following command and paste it here.(https://github.com/settings/ssh)

			cat ~/.ssh/id_rsa.pub

			Once you've done this, you can check and see if it worked:

			ssh -T git@github.com

			You should get a message like this:

			Hi excid3! You've successfully authenticated, but GitHub does not provide shell access.


			=Installing Rails=

			Aktuelle Version: 6.0.2.1

			gem install rails -v 6.0.2.1

			If you're using rbenv, you'll need to run the following command to make the rails executable available:

			rbenv rehash

			Now that you've installed Rails, you can run the '''rails -v''' command to make sure you have everything installed correctly:

			rails -v
			# Rails 6.0.2.1

			If you get a different result for some reason, it means your environment may not be setup properly.


			=Setting UP MySQL=


			Rails ships with sqlite3 as the default database. Chances are you won't want to use it because it's stored as a simple file on disk. You'll probably want something more robust like MySQL or PostgreSQL.

			There is a lot of documentation on both, so you can just pick one that seems like you'll be more comfortable with. If you're coming from PHP, you may already be familiar with MySQL. If you're new to databases, I'd suggest skipping to '''setting up PostgreSQL'''. (https://gorails.com/setup/ubuntu/19.10#postgres)

			You can install MySQL server and client from the packages in the Ubuntu repository. As part of the installation process, you'll set the password for the root user. This information will go into your Rails app's '''database.yml''' file in the future.


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

			Installing the '''libmysqlclient-dev''' gives you the necessary files to compile the '''mysql2''' gem which is what Rails will use to connect to MySQL when you setup your Rails app.


			When you're finished, you can '''skip to the Final Steps'''.

			Next we're going to be installing Ruby using one of three methods. Each have their own benefits, most people prefer using rbenv these days, but if you're familiar with rvm you can follow those steps as well. I've included instructions for installing from source as well, but in general, you'll want to choose either rbenv or rvm.

			'''Choose one method.''' Some of these conflict with each other, so choose the one that sounds the most interesting to you, or go with my suggestion, rbenv.

			==Using rbenv (recommended)==

			Installing with rbenv is a simple two step process. First you install '''rbenv''', and then '''ruby-build''':

			cd
			git clone https://github.com/rbenv/rbenv.git ~/.rbenv
			echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
			echo 'eval "$(rbenv init -)"' >> ~/.bashrc
			exec $SHELL

			git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
			echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
			exec $SHELL

			rbenv install 2.7.0
			rbenv global 2.7.0
			ruby -v


			The last step is to install Bundler

			gem install bundler

			rbenv users need to run '''rbenv rehash''' after installing bundler.

Installation von Ruby on Rails auf Ubuntu 16.04

Quelle: https://gorails.com/setup/ubuntu/16.04

Aktuelleste Version: 2.7.0 (Stand 24.03.2020)

=Overview=

We will be setting up a Ruby on Rails development environment on Ubuntu 16.04 Xenial Xerus.

The reason we're going to be using Ubuntu is because the majority of code you write will run on a Linux server. Ubuntu is one of the easiest Linux distributions to use with lots of documentation so it's a great one to start with.

You'll want to download the latest Desktop version here: http://releases.ubuntu.com/16.04/

Some of you may choose to develop on Ubuntu Server so that your development environment matches your production server. You can find it on the same download link above.

=Installing Ruby=

The first step is to install some dependencies for Ruby and Rails.

To make sure we have everything necessary for Webpacker support in Rails, we're first going to start by adding the Node.js and Yarn repositories to our system before installing them.

sudo apt install curl
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
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 apt-get update
sudo apt-get install git-core 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 nodejs yarn
