~/var/canvas$ sudo chown -R helpdesk /var/canvas   --- helpdesk just happens to be the name of this user.  use your own 

Download Ruby 2.1.6

You're going to have to add a repository because the version available through Ubuntu's US or Main repos is not up to date (at the time of this writing.

~/var/canvas$ sudo apt-get -y install software-properties-common
~/var/canvas$ sudo apt-add-repository ppa:brightbox/ruby-ng

~/var/canvas$ sudo gem install bundler --version 1.7.11
~/var/canvas$ bundle install --path vendor/bundle --without=sqlite mysql

Download default config files from Amazon instance

~/var/canvas$ for config in amazon_s3 database \
  delayed_jobs domain file_store outgoing_mail security external_migration
do cp config/$config.yml.example config/$config.yml; done

Configuration

database.yml

~/var/canvas$ cp ./config/database.yml.example ./config/database.yml
~/var/canvas$ vi config/database.yml

Under Production

• edit the database name (if different from default)default=canvas_production & canvas_queue_production
• host (if different from default) default=localhost
• username for database user (if different from default) default=canvas
• password for database user

In my instance, nothing was changed except the password.

production:
 adapter: postgresql
 encoding: utf8
 database: canvas_production
 host: localhost
 username: canvas
 password: password
 timeout: 5000
 queue:
   adapter: postgresql
   encoding: utf8
   database: canvas_queue_production
   host: localhost
   username: canvas
   password: password
   timeout: 5000

outgoing_mail.yml

~/var/canvas$ cp ./config/outgoing_mail.yml.example ./config/outgoing_mail.yml
~/var/canvas$ vi config/outgoing_mail.yml

Under Production

• Edit the address, this should be your email relay or SMTP server
• Edit the port (if different from default) default=25
• Edit the username for your relay/smtp
• Edit the password for your relay/smtp
• Edit the domain (if different from default) default=example.com
• Edit the outgoing address (if different from default) [email protected]

In my instance, I only changed the address, username, password, domain, and outgoing_address

production:
 address: "smtp.example.com"
 port: "25"
 user_name: "user"
 password: "password"
 authentication: "plain" # plain, login, or cram_md5
 domain: "example.com"
 outgoing_address: "[email protected]"
 default_name: "Instructure Canvas"

domain.yml

~/var/canvas$ cp ./config/domain.yml.example ./config/domain.yml
 ~/var/canvas$ vi config/domain.yml

Under Production

• Edit the domain
• Uncomment the files domain and add your domain

In my instance, I only changed the domain and uncommented the files domain

production:
 domain: "canvas.example.com"
 # whether this instance of canvas is served over ssl (https) or not
 # defaults to true for production, false for test/development
 ssl: true
 files_domain: "canvasfiles.example.com"

security.yml

~/var/canvas$ cp ./config/security.yml.example ./config/security.yml
 ~/var/canvas$ vi config/security.yml

Under Production

• Edit the encryption Key to a minimum of 20 characters. This can be random.

In my instance, I only changed the encryption key by pressing alot of buttons

production:
 # replace this with a random string of at least 20 characters
 encryption_key: hu9ehd92hdh2798ehdrd2hd37824   ---(no this is not really my encryption key)

Database Population

~/var/canvas$ RAILS_ENV=production bundle exec rake db:initial_setup

You will be asked the following questions:

What email address will the site administrator account use? > 
Please confirm > 
What password will the site administrator use? >
Please confirm >
What do you want users to see as the account name? This should probably be the name of your organization. >

To help our developers better serve you, Instructure would like to collect some usage data about your Canvas installation. You can  
change this setting at any time.:
1. Opt in
2. Only send anonymized data

File Generation

~/var/canvas$ sudo mkdir -p log tmp/pids public/assets public/stylesheets/compiled
~/var/canvas$ sudo touch Gemfile.lock
~/var/canvas$ npm install
~/var/canvas$ RAILS_ENV=production bundle exec rake canvas:compile_assets

Ownership limitations

I did this with www-data as this user exists by default with Apache installtions on Ubuntu.
Verify www-data exists:

~/var/canvas$ awk -F':' '{ print$1}' /etc/passwd
...
www-data
...

Limit read access

 ~/var/canvas$ sudo chown -R www-data config/environment.rb log tmp public/assets public/stylesheets/compiled Gemfile.lock config.ru
 ~/var/canvas$ sudo chown www-data ./config/*.yml
 ~/var/canvas$ sudo chmod 400 ./config/*.yml

Apache2 install/config

Unfortunately we need to add a repo before we can install passenger-common1.9.1 as it is not found in the normal 14.04 repo:

E: Unable to locate package passenger-common1.9.1
E: Couldn't find any package by regex 'passenger-common1.9.1'

Add the new repo

~$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 561F9B9CAC40B2F7
~$ sudo apt-get install -y apt-transport-https ca-certificates
~$ sudo sh -c 'echo deb https://oss-binaries.phusionpassenger.com/apt/passenger trusty main > /etc/apt/sources.list.d/passenger.list'
~$ sudo apt-get update

Now you should be able to install the required dependencies.

~$ sudo apt-get install -y passenger-common1.9.1 libapache2-mod-passenger apache2
