AWS EC2 API tools: Installation

AWS EC2 API tools help too much for Amazon EC2 to register and launch instances, manipulate security groups, and more. Someone asked me to backup EC2 instance. I thought to use it for backup script. Anyway, No need to explain more how to install Amazon EC2 API tools on Ubuntu? Just say thank for  EC2StartersGuide. I fellow this link and installed it easily. Additional, I used this Link for more idea about java.
- Adding Repository and Install EC2 API tools.

ubuntu@ip-x-x-x-x:~$ sudo apt-add-repository ppa:awstools-dev/awstools
 Up to date versions of several tools from AWS.
 Use this repository by:
 sudo apt-add-repository ppa:awstools-dev/awstools
 sudo apt-get update
 sudo apt-get install ec2-api-tools
.
.
.
ubuntu@ip-x-x-x-x:~$ sudo apt-get update
ubuntu@ip-x-x-x-x:~$ sudo apt-get install ec2-api-tools
ubuntu@ip-x-x-x-x:~$ sudo apt-get install -y openjdk-7-jre
ubuntu@ip-x-x-x-x:~$ file $(which java)
/usr/bin/java: symbolic link to `/etc/alternatives/java'
ubuntu@ip-x-x-x-x:~$ file /etc/alternatives/java
/etc/alternatives/java: symbolic link to `/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java'

- Adding variables in ~/.bashrs file. We should have "Access Key" - Security Credentials.

ubuntu@ip-x-x-x-x:~$ vi ~/.bashrc
.
.
.
export EC2_KEYPAIR=***
export EC2_URL=https://ec2.ap-southeast-1.amazonaws.com
export EC2_PRIVATE_KEY=$HOME/.ec2/pk-***.pem
export EC2_CERT=$HOME/.ec2/cert-***.pem
export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/jre
ubuntu@ip-x-x-x-x:~$ source ~/.bashrc

- If everything's all right. Time to use it.
