Installation of Canvas on Ubuntu 12.04 LTS on VMWare Virtual Machine

[a...@anotherspot.com]

Hello,

After following the production guide many times and seeing as more fails than successes in building our test servers I though I'd share a walkthrough of our current setup.

Although not guaranteed to work it seems to work for me - The securing portion still needs some extra effort. 

You'll see some snapshots along the way. Not needed but helped get me out of trouble a couple of times.

Happy for any improvements to be suggested.

Installation was from Ubuntu Server 12.04 LTS with defaults - only package selected in installation was OpenSSH.

sudo apt-get install linux-virtual linux-image-virtual linux-headers-virtual

Hi,

I have tried your method but getting error while initializing the DB.

RAILS_ENV=production bundle exec rake db:initial_setup  

   rake aborted!
FATAL:  password authentication failed for user "canvas"

My database.yml file is as follows;

# do not create a queue: section for your test environment
test:
  adapter: postgresql
  encoding: utf8
  database: canvas_test
  host: localhost
  username: canvas
  timeout: 5000

test-in-memory:
  adapter: sqlite3
  encoding: utf8
  database: ':memory:'
  pool: 1

development:
  adapter: postgresql
  encoding: utf8
  database: canvas_development
  timeout: 5000
  queue:
    adapter: postgresql
    encoding: utf8
    database: canvas_queue_development
    timeout: 5000

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

what about the rest of your guide? apache sites-available/canvas config?

[irfan...@enovatemedia.com]

you can get the apache virtualhost site configuration from https://github.com/instructure/canvas-lms/wiki/Production-Start

In my case the same error occured when the password not quotd. And solved now.
