GNU/Linux - Ubuntu 12.04

These scripts are tested on Ubuntu Desktop 12.04 LTS 64 bit GNU/Linux. Why 64 bit? Because Apache BigTop only provides 64 bit deb/rpm packages. Besides, to run 64 bit VirtualBox images, you also need a 64 bit host OS.

### How to check your OS version
~$ uname -a
Linux EA-dev 3.8.0-29-generic #42~precise1-Ubuntu SMP Wed Aug 14 16:19:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
~$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:  Ubuntu 12.04.4 LTS
Release:  12.04
Codename: precise

git

To checkout the github repository, you need to install git.

### Install git on Ubuntu 12.04
~$ sudo apt-get -y install git
### How to check your git version
~$ git --version
git version 1.7.9.5

VirtualBox

Some scripts are tested on local virtualbox VMs, you need to install virtualbox before running these scripts. Due to PXE boot issue of some NICs, we suggest to run official virtualbox instead of ubuntu package (4.1.12_Ubuntur77245). Please install official virtualbox rpm/deb/exe for your environment.

### Install VirtualBox on Ubuntu 12.04
~$ echo "deb http://download.virtualbox.org/virtualbox/debian precise contrib" > virtualbox.list
~$ sudo mv virtualbox.list /etc/apt/sources.list.d/
~$ wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add -
~$ sudo apt-get update; sudo apt-get -y install virtualbox-4.3
### How to check your virtualbox version
~$ vboxmanage --version
4.3.10r93012

Vagrant

These scripts are based on Vagrant 2 syntex, so you can not use the default ubuntu package (1.0.1). Please install official vagrant rpm/deb/exe for your environment.

### Install official vagrant package on Ubuntu
~$ wget https://dl.bintray.com/mitchellh/vagrant/vagrant_1.5.2_x86_64.deb
~$ sudo dpkg -i vagrant_1.5.2_x86_64.deb 
### How to check your vagrant version
~$ vagrant --version
Vagrant 1.5.2

Amazon EC2 Access Key

To run virtual machines on Amazon EC2, you need to register AWS account. We will use Amazon EC2 API Tools to simplify some web operations. Please reference Ubuntu community Wiki "EC2 Starter's Guide" to register account, intall ec2-api-tools and configure environment variables.

### Install ec2-api-tools on Ubuntu
~$ sudo apt-get -y install ec2-api-tools
### How to check your ec2-api-tools
~$ dpkg -l ec2-api-tools 
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name                           Version                        Description
+++-==============================-==============================-============================================================================
ii  ec2-api-tools                  1.5.0.0-0ubuntu1               Amazon EC2 API tools

set up your Amazon API credentials. Go to Account -> Security Credentials

• click "Access Keys (Access Key ID and Secret Access Key)" tab
• Create a new Certificate
• Download the root key and save it in ~/.ec2/rootkey.csv
• Make your credential files private: chmod go-rwx ~/.ec2/*.csv

~$ mkdir -p ~/.ec2
### download Access Key Certificates and private key into ~/.ec2
~$ chmod go-rwx ~/.ec2/*.csv
### generate a shell script for furthur 
~$ source ~/.ec2/rootkey.csv
~$ cat > ~/.ec2/ec2_keys << EOF
export EC2_URL=https://ec2.ap-southeast-1.amazonaws.com
export AWS_ACCESS_KEY=$AWSAccessKeyId
export AWS_SECRET_KEY=$AWSSecretKey
export AWS_KEYPAIR_NAME=vagrant
export AWS_KEYPAIR_PATH=~/.ec2/vagrant.pem
export AWS_SEC_GROUPS=default
EOF
~$ source ~/.ec2/ec2_keys
### generate keypair named by 'vagrant' and store the private key in ~/.ec2/vagrant.pem
~$ ec2-create-keypair vagrant > ~/.ec2/vagrant.pem

"vagrant-aws" plugin

To run some example vagrant script for AWS EC2, please install vagrant-aws plugin.

### Install vagrant-aws plugin
~$ vagrant plugin install vagrant-aws
### How to check installed plugins
~$ vagrant plugin list
vagrant-aws (0.4.1)
vagrant-login (1.0.1, system)
vagrant-share (1.0.1, system)
### Add 'dummy' box for 'vagrant-aws' plugin
~$ vagrant box add dummy https://github.com/mitchellh/vagrant-aws/raw/master/dummy.box

Get the source code

You can check out the source code with following commands

~$ git clone https://github.com/jazzwang/vagrant-hadoop

Example 1 : run bigtop example on local virtualbox

The first example is to run BigTop single node Hadoop on AWS EC2.

~$ cd vagrant-hadoop/bigtop-aws/ubuntu
~/vagrant-hadoop/bigtop-aws/ubuntu$ vagrant up bigtop1

You could login local virtualbox instance with vagrant ssh

~/vagrant-hadoop/bigtop-aws/ubuntu$ vagrant ssh bigtop1

Example 2 : run bigtop example on remote EC2

~$ cd vagrant-hadoop/bigtop-aws/ubuntu
~/vagrant-hadoop/bigtop-aws/ubuntu$ source ~/.ec2/ec2_keys
~/vagrant-hadoop/bigtop-aws/ubuntu$ vagrant up --provider=aws

You could get the public ip of your EC2 instances with ec2-describe-instance-status command.

~/vagrant-hadoop/bigtop-aws/ubuntu$ ec2-describe-instance-status

You could login remote EC2 instance with vagrant ssh

~/vagrant-hadoop/bigtop-aws/ubuntu$ vagrant ssh bigtop2

Note: Please shutdown your EC2 instance after testing with command vagrant halt, or it will take USD 0.077 in Singapore region.

~/vagrant-hadoop/bigtop-aws/ubuntu$ vagrant halt bigtop2

To complete terminate your EC2 instance, you could use the command vagrant destroy -f.

~/vagrant-hadoop/bigtop-aws/ubuntu$ vagrant destroy -f bigtop2
