资源说明：Vagrant config for Ubuntu VM with R, under EC2
# Vagrant-EC2-R
This repository shows how to use the same `chef-solo`-based provisioning scheme for Vagrant virtual machines and Amazon's EC2. This is useful because you'll be able to test the deployment procedures as you develop within a clean Vagrant machine. Running continuous deployment locally also saves tons of partial instance-hours, which can run into the hundreds of cents (I'm not made of money, people).
These scripts have been tested only on Mac OS X 10.7.
# Development (local)
### One-time setup of for local virtual machines
* Install [Vagrant](http://vagrantup.com). (On Linux, `gem install vagrant`)
* Install [VirtualBox 4](http://www.virtualbox.org/wiki/Downloads)
* Add the `precise64` vagrant base image to Vagrant's local storage: `vagrant box add precise64 http://files.vagrantup.com/precise64.box`
### Create and provision local virtual machines
After this is done, you can create the VM with Vagrant:
cd a_vagrant_machine/
vagrant up
vagrant ssh
To delete the virtual machine, run:
vagrant destroy
# Production (EC2)
### One-time setup of local machine for EC2
On your local machine, you will need the following:
* Do steps 1-11 from [this page](http://petterolsson.blogspot.com/2012/02/installing-amazon-ec2-api-tools-on-mac.html).
* On Linux, instead of doing step 8, installing the EC2 command-line tools manually, they can be installed with `apt-get`. See the section on Linux below for more information.
* Instead of step 12, put the following in your `~/.profile`. Make sure that the `JAVA_HOME` is appropriate for your system; if you have a Mac, delete the line for Linux:
```
# Setup Amazon EC2 Command-Line Tools
export EC2_HOME=~/.ec2
export PATH=$PATH:$EC2_HOME/bin
export EC2_PRIVATE_KEY=`echo $EC2_HOME/pk-*.pem`
export EC2_CERT=`echo $EC2_HOME/cert-*.pem`
export JAVA_HOME=`/usr/libexec/java_home` # On Mac
export JAVA_HOME=/usr/lib/jvm/default-java # On Ubuntu linux
```
* Make sure you have the JSON Ruby gem installed:
```
gem install --user-install json
```
* Create a key pair in the appropriate region. In this case the region is `us-west-1`, and we'll use the name `test-ec2-keypair`:
```
ec2-add-keypair --region us-west-1 test-ec2-keypair > ~/.ec2/test-ec2-keypair
chmod 600 ~/.ec2/test-ec2-keypair
```
After you do all these things, you will need to start a new terminal, or simply run all the `export` lines (that you added to your `~/.profile`) from your command line.
### Create and provision virtual machines on EC2
Do the following each time you want to create a virtual machine on EC2.
Go to the directory containing this project, then start up a new EC2 instance (`ami-87712ac2` is a Ubuntu 12.04 64-bit server in region `us-west-1`):
cd vagrant-ec2-r/
ec2-run-instances ami-87712ac2 --region us-west-1 --instance-type t1.micro --key test-ec2-keypair --user-data-file bootstrap.sh
NOTE: you may need to also set the security group with `--group `.
The default security group might not allow any connections to the machine; you will need to at the very least allow incoming ssh connections.
Find its IP address with:
ec2-describe-instances --region us-west-1
After the machine boots up, provision it using the same recipes as the demo Vagrant machine machine:
./setup.sh a_vagrant_machine/ ~/.ec2/test-ec2-keypair
It should print a lot of diagnostic info to the terminal. If it doesn't, wait a little while and try again.
DONE!
You can ssh into the machine:
ssh -i ~/.ec2/test-ec2-keypair ubuntu@
This will terminate your instances when you're finished:
ec2-terminate-instances --region us-west-1
# Converting existing Vagrantfiles
Just add three lines in the provisioning section of your `Vagrantfile` so it looks like this:
config.vm.provision :chef_solo do |chef|
require 'json'
open('dna.json', 'w') do |f|
chef.json[:run_list] = chef.run_list
f.write chef.json.to_json
end
open('.cookbooks_path.json', 'w') do |f|
f.puts JSON.generate([chef.cookbooks_path]
.flatten
.map{|x| File.expand_path(x)})
end
end
# Set up notes
## Installing EC2 command line tools in Ubuntu Linux
The EC2 command line tools can be installed by enabling the "multiverse" repositories. In `/etc/apt/sources.list`, uncomment the lines that end with `multiverse`. For example:
deb http://us.archive.ubuntu.com/ubuntu/ precise multiverse
deb http://us.archive.ubuntu.com/ubuntu/ precise-updates multiverse
Then run:
sudo apt-get update
sudo apt-get install ec2-api-tools
