min requirements and env for ec2-api-tools

I started a mini Fedora EC2 instance on Amazon Web Services the other day. The instance had a slim set of installed programs. Here is the short list of dependencies to get the ec2-api-tools running:

• yum install openssh-clients (for SCP)
• yum install unzip (for the zipped ec2-api-tools install zip)
• install latest jdk (latest 6_27 from Oracle's site)

As well, ec2-api-tools depends on a a few environment variables..the five lines at the bottom of this .bash_profile:

export PATH

export HADOOP_HOME=/usr/lib/hadoop-0.20

export HIVE_HOME=/usr/lib/hive

export MYBUCKET=frasestrendingtopics

export MYSERVER=localhost

export MAILTO=cacasododom@gmail.com

export JAVA_HOME=/usr/java/jdk1.6.0_24/

export EC2_HOME=/usr/bin/ec2-api-tools-1.4.4.0

export EC2_PRIVATE_KEY=~/doc/software/amazon/certs/pk-GEQDDYWBHKJKKUWNWAS.pem

export EC2_CERT=~/doc/software/amazon/certs/cert-DYWBHKJKKUWNWASYNF2YL.pem

export ACCESS_KEY_ID=8DSRMMTFQMQRER2

export SECRET_ACCESS_KEY=mAq9QzCVhmxzKpxhQxBoA5jOxZksq62jpO5mbD

ec2 api tools through an http proxy

I spent about an hour on this today so I thought it would be reasonable to post about it. I was trying to access the EC2 API tools behind my firewall at work, through our http proxy server. You can get this to work by setting a JVM environment variable called EC2_JVM_ARGS like so. Example is from a Linux box.

Example without username authentication (using ntlmaps)
export EC2_JVM_ARGS="-DproxySet=true -DproxyHost=localhost -DproxyPort=5865 -Dhttps.proxySet=true -Dhttps.proxyHost=localhost -Dhttps.proxyPort=5865"

Example with username authentication
export EC2_JVM_ARGS="-DproxySet=true -DproxyHost=http-proxy -DproxyPort=8080 -Dhttps.proxySet=true -Dhttps.proxyHost=http-proxy -Dhttps.proxyPort=8080 -Dhttp.proxyUser=username -Dhttp.proxyPass=password -Dhttps.proxyUser=username -Dhttps.proxyPass=password"

Voila..it works!
