Bootstrapping files for creating a Ruby on Rails server on an Tested on Ubuntu 12.04 server, with Ruby on Rails 3.2.7 and Ruby 1.9.3-p125
Blank Ubuntu 12.04 server machine with SSH access
Make sure on your machine which you are running the chef commands from that you have ruby, chef & knife-solo installed
gem install chef knife-solo
Create a new node
cd nodes cp ../node-templates/webserver.json <Server IP>.json
Edit <Server IP>.json file and change username and password to anything you like and remove or add cookbooks if you want.
NOTE: Your ‘dbuser’ should be the same as your ‘linuxuser’.
Prepare the server, ie: bootstap & install chef.
knife prepare <user>@<Server IP>
Optional: install ssh-copy-id for passwordless ssh setup to your server
ssh-copy-id <user>@<Server IP>
Run chef-solo on server
knife cook <user>@<Server IP>
NOTE: Sometimes I’ve had to re-run the prepare again for the cook to work properly.
This part maybe handled by using passenger_apache2.
Edit /etc/apache2/sites-enabled/rails_project, and follow the example
You may have to restart apache2 on the server
sudo service apache2 restart
Restarting apache2 from your DEV box.
cap passenger:restart
Max pool size should be set to ‘2’ for VPS’s with 256MB RAM. Default is 6. This is set in the /etc/apache2/sites-enabled/rails_project.
ssh into your server and do
ssh-keygen -t rsa -C "your_email@youremail.com" cat .ssh/id_rsa.pub
Testing with
git clone git@github.com:map7/venuebat.git
Copy the .ssh/id_rsa.pub file into your github profile.
The next step after your machine is setup is to setup capistrano for deployment.
Use capistrano to deploy your app. <config deploy.rb>
cap deploy:setup cap deploy:cold
ssh into server and do the following
cd /srv/<project>/shared mkdir config
Assuming you have a database.yml.example file you could do
mkdir /srv/<project>/shared/config cp /srv/<project>/current/config/database.yml.example /srv/<project>/shared/config/database.yml
Now edit your database.yml file so that it has only the production database details in it.
You can now create and seed the database
cap deploy:cold cap deploy:seed cap deploy:restart
If you want to update a Gem make sure you explicitly state the version number in the Gemfile before deploying.
EG: gem ‘gmaps4rails’, ‘1.5.2’
gems are placed in the shared/bundle directory and will not show up with ‘gem list’ on the server.
If you are getting the following error
Passenger encountered the following error: The application spawner server exited unexpectedly: Unexpected end-of-file detected.
Upgrade passenger to 3.0.14
sudo gem update passenger passenger-install-apache2-module
Setup your server using the mythbuntu 11.04 or higher distro.
During the install
- Select to download codecs etc
- Setup drives like so:
- Select all services
- Setup as a frontend & backend.
- Select your remote control
| mount point | type | size |
| / | ext4 | 20GB |
| /home | ext4 | 30GB |
| /var/lib/mythtv/overlays | ext4 | 10GB |
| /var/lib/mythtv | xfs | * |
./deploy.sh <user>@<host> mythtv.json
I typically put my video drives in /storage? (where ? is the number of the drive)
If you want to share a /storage? directory then look at /etc/samba/smb.conf
You must have a ruby installed in the system otherwise chef will install your gem into the embedded area (opt/chef/embedded/bin)
gem_package = Installs into the system area chef_gem = Installs into embedded area for use in chef scripts.
