不要使用一部安装，以为程序安装的时候进行了如下检查：
## Sanity check
##
if [[ ! "$(lsb_release -d | cut -f2)" =~ $'Ubuntu 12.04' ]]; then
echo "This script is only known to work on Ubuntu 12.04, exiting...";
exit;
fi
用分布安装，安装步骤如下：
##
## Update and Upgrade apt packages
##
sudo apt-get update -y
sudo apt-get upgrade -y
##
## Install system pre-requisites
##
sudo apt-get install -y build-essential software-properties-common python-software-properties curl git-core libxml2-dev libxslt1-dev python-pip python-apt python-dev
sudo pip install --upgrade pip
sudo pip install --upgrade virtualenv
##
## Clone the configuration repository and run Ansible
##
cd /var/tmp
git clone -b release https://github.com/edx/configuration
##
## allow password based SSH authentication,
## edit the common role inside of
## configuration/playbooks/roles/common/defaults/main.yml and
## set COMMON_SSH_PASSWORD_AUTH to "yes"
##
##
## Install the ansible requirements
##
cd /var/tmp/configuration
sudo pip install -r requirements.txt
##
## Run the edx_sandbox.yml playbook in the configuration/playbooks directory
