How to setup Amazon EC2 API on Linux Machine

OBJECTIVE

The objective of this how to is to enable the use of various command line tools of Amazon such as EC2 API, S3 API, Route53 API, etc.

GETTING STARTED

  • After downloading java archive on the server, we are now ready to setup java environment.
  • Create java directory
[[email protected] ~]# mkdir /usr/java/

  • Next untar jdk into /usr/java/ folder & create the soft links as follows
[[email protected] ~]# cd /usr/java/
[[email protected] java]# ll
total 4
lrwxrwxrwx 1 root root   16 Jun 10  2010 default -> /usr/java/latest
drwxr-xr-x 9 root root 4096 Jun  8  2010 jdk1.6.0_14
lrwxrwxrwx 1 root root   21 Jun 10  2010 latest -> /usr/java/jdk1.6.0_14
[[email protected] java]#
  • Now the last step is to setup JAVA_HOME in user’s environment
[[email protected] java]# cd
[[email protected] ~]# vim .bashrc
# JAVA Home
export JAVA_HOME=/usr/java/default

  • After saving the ~/.bashrc file, source it so that the changes can be added to the environment variables
[[email protected] ~]# source .bashrc
[[email protected] ~]# echo ${JAVA_HOME}
/usr/java/default
[[email protected] ~]#

  • Now the common step among almost all Amazon APIs is that they require Amazon account certificate file, private key file, Access key & secret key. So we are going to setup these 4 variables
  • We created a folder named keys in root’s home
[[email protected] ~]# mkdir /root/keys/
[[email protected] ~]# cd keys/
[[email protected] keys]# chmod 0600 *.pem
[[email protected] keys]# ll
-rw------- 1 root root  916 Sep 30  2011 cert-XUXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.pem
-rw------- 1 root root  928 Sep 30  2011 pk-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.pem

  • Now we access Amazon console -> security credentials & copied Access Key & Secret Key to some file. We setup these two keys & above two .pem files path in user’s ~/.bashrc & source it to add the changes to user’s environment
[[email protected] keys]# cd
[[email protected] ~]# vim .bashrc
export AWS_ACCESS_KEY_ID=xxxxxxxxxxxxxxxxxxxxxx
export AWS_SECRET_ACCESS_KEY=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
export EC2_PRIVATE_KEY=/root/keys/pk-XXXXXXXXXXXXXXXXXXXXXXXXXX.pem
export EC2_CERT=/root/keys/cert-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.pem
[[email protected] ~]# source .bashrc

[[email protected] ~]# cd ~/Downloads/
[[email protected] Downloads]# wget http://s3.amazonaws.com/ec2-downloads/ec2-api-tools.zip

[[email protected] Downloads]# unzip ec2-api-tools.zip

  • Now we are moving ec2-api-tools folder in /home/ directory as ec2
[[email protected] Downloads]# mv ec2-api-tools-1.6.6.0/ /home/ec2

  • Then again we will setup our ~/.bashrc with EC2 API commands in user’s environment
[[email protected] Downloads]# cd
[[email protected] ~]# vim .bashrc
export EC2_HOME=/home/ec2
export PATH=$PATH:/home/ec2/bin
[[email protected] ~]# source .bashrc

  • Now it’s time to test if all the setup, keys, etc are working as expected or not
