Setup Server for Rails app

Step 1. Clone chefrails

git clone http://github.com/wongyouth/chefrails.git

Step 2. Install ruby gems

cd chefrails
bundle install

Step 3. Prepare your databag. Create user deploy for deployment

cp data_bags/users/deploy.json.example data_bags/users/deploy.json

# Create your own password for deploy user. I use `deploy` as password in the deploy.json.example.
openssh password -1 "your password"

# open file below to paste created password, ssh_keys
vi data_bags/users/deploy.json

Step 4. Cook your recipes

knife solo bootstrap root@your_server

It will take a couple minutes, have a cup of tea and Enjoy!

Test with Vagrant

It's no different between vagrant server or not. The Vagrantfile file is just a basic setup which use precise64 as server. What we need to do with Vagrant is to setup a login username and server info.

Install Vagrant

gem install vagrant
vagrant up

Setup SSH

vagrant ssh-config --host chefrails >> ~/.ssh/config

Same Step 1~3, for Step 4. use vagrant username and server

knife solo bootstrap vagrant@chefrails

QA

1. Exit with error message: DEBUG: chef_gem[treetop] no installed version found for treetop (>= 1.4)

That because Chef cannot get gem treetop installed from https://rubygems.org in China.

Workaround is to change gem sources to taobao mirror.

/opt/chef/embedded/bin/gem sources --remove https://rubygems.org/ /opt/chef/embedded/bin/gem sources --add http://ruby.taobao.org/

2. apt-get update caused a lot of time to complete.

Change to a mirror in China.

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak sudo sed -e 's/us.archive/cn.archive/' -i /etc/apt/sources.list

3. Server hanging while install chef

It's difficult to install chef within China. You can download chef client from chef.io and install directly on your server.

If you use Ubuntu, you can download a debian version of chef client. and install it by

dpkg -i chef_12.4.0-1_amd64.deb
