Canvas - Learning Management Solution. Used by universities and schools.
Requirements
In the simplest configuration, everything will be running off a single server.
- Recommended Hardware specifications
- Dual Core+ 3.0ghz+ or Dual processors
- 4GB+ RAM
- 60GB HDD
- 64-bit capable system
Software Requirments
Minium, Ubuntu 10.04 LTS+ server edition. Desktop will require more hardware than listed above.
Preferably Ubuntu 12.04 LTS
If you are having trouble loading 12.04 LTS, try upgrading from 10.04. Instructions here
Download Database software
Postgres (Database)
~$ sudo apt-get update && sudo apt-get -y upgrade && sudo apt-get -y autoremove ~$ sudo apt-get -y install postgresql-9.1
Configure Database
~$ sudo -u postgres createuser canvas -D -S -R -P ~$ sudo -u postgres createdb canvas_production --owner=canvas ~$ sudo -u postgres createdb canvas_queue_production --owner=canvas
Download Git & Canvas
~$ sudo apt-get -y install git-core ~$ cd /var ~$ sudo git clone https://github.com/instructure/canvas-lms.git canvas ~$ cd canvas ~/var/canvas$ sudo git branch --set-upstream stable origin/stable ~/var/canvas$ sudo chown -R helpdesk /var/canvas --- helpdesk just happens to be the name of this user. use your own
Download Ruby 1.9.3
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 python-software-properties ~/var/canvas$ sudo apt-add-repository ppa:brightbox/ruby-ng ~/var/canvas$ sudo apt-get update ~/var/canvas$ sudo apt-get -y install ruby1.9.3 zlib1g-dev libxml2-dev libmysqlclient-dev libxslt1-dev imagemagick libpq-dev nodejs libxmlsec1-dev libcurl4-gnutls-dev libxmlsec1 build-essential openjdk-7-jre
Download Ruby Gems
If you are behind a firewall, you're going to need to open up the following routes to complete this sections' installation instructions:
- 192.30.252.128:9418
- 192.30.252.129:9418
- 192.30.252.130:9418
- 192.30.252.131:9418
~/var/canvas$ sudo gem install bundler --version 1.3.5 ~/var/canvas$ bundle install --path vendor/bundle --without=sqlite
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/cavnas$ 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 3. Opt out completely >
File Generation
~/var/canvas$ 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$1}' /etc/passwd ... www-data ...
Create directories and set permissions.
~/var/canvas$ sudo mkdir -p log tmp/pids public/assets public/stylesheets/compiled ~/var/canvas$ sudo touch Gemfile.lock ~/var/canvas$ sudo chown -R www-data config/environment.rb log tmp public/assets public/stylesheets/compiled Gemfile.lock config.ru
Limit read access
~/var/canvas$ sudo chown www-data config/*.yml ~/var/canvas$ sudo chmod 400 config/*.yml
Apache2 install/config
~/var/canvas$ sudo apt-get -y install passenger-common1.9.1 libapache2-mod-passenger apache2 ~/var/canvas$ sudo a2enmod rewrite ~/var/canvas$ sudo service apache2 restart
Verify that symlinks exist for the passenger mods:
~/var/canvas$ cd /etc/apache2/mods-enabled/ ~/etc/apache2/mods-enabled$ ls ... passenger.conf passenger.load ....
In my installation, I did not do the following:
Permission issues, see Configure Passenger with Apache on the Production start guide for Canvas
Apache 2 SSL config
~/var/canvas$ sudo a2enmod ssl ~/var/canvas$ sudo service apache2 restart
Canvas Apache2 config
Disable the default site
~/var/canvas$ sudo a2dissite 000-default ~/var/canvas$ sudo service apache2 restart
Create the canvas apache config file
~/var/canvas$ sudo nano /etc/apache2/sites-available/canvas
Paste the following into the new file:
<VirtualHost *:80> ServerName canvas.example.com ServerAlias files.canvas.example.com ServerAdmin [email protected] DocumentRoot /var/canvas/public RewriteEngine On RewriteCond %{HTTP:X-Forwarded-Proto} !=https RewriteCond %{REQUEST_URI} !^/health_check RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L] ErrorLog /var/log/apache2/canvas_errors.log LogLevel warn CustomLog /var/log/apache2/canvas_access.log combined SetEnv RAILS_ENV production <Directory /var/canvas/public> Allow from all Options -MultiViews </Directory> </VirtualHost> <VirtualHost *:443> ServerName canvas.example.com ServerAlias files.canvas.example.com ServerAdmin [email protected] DocumentRoot /var/canvas/public ErrorLog /var/log/apache2/canvas_errors.log LogLevel warn CustomLog /var/log/apache2/canvas_ssl_access.log combined SSLEngine on BrowserMatch "MSIE [2-6]" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0 BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown # the following ssl certificate files are generated for you from the ssl-cert package.

Modify the following values in the new canvas config file:
<VirtualHost *:80> ServerName [value] ServerAlias [value] ServerAdmin [value] DocumentRoot [value] ... SetEnv [value] <Directory [value]> ... </VirtualHost> <VirtualHost *:443> ServerName [value] ServerAlias [value] ServerAdmon [value] DocumentRoot [value] ...
