1. Sign up to AWS http://aws.amazon.com (1 year free for now: Dec 09 2014) and choose EC2
2. Choose a server.
I’am selecting Ubuntu.
3. Choose an instance type.
4. Configure number of instances.
Change the number of instances to 4 and everything else will be default.
5. Add Storage.
Just let it be!
6. Give the instance name and description.
7. Define a Security Group.
8. Review Instance Launch.
Lets just launch. Once you click “Launch” 4 instance should be launched with “pending” state.
9. Create Security Pair.
10. Launching Instances and give names.
Once in “running” state we can give names like below.
HadoopNameNode (Master)
HadoopSecondaryNameNode
HadoopSlave1 (data node will reside here)
HaddopSlave2 (data node will reside here)
11. Let’s connect to the master server.
First, check the permission of the ‘pem’ file you received on ‘9. Create Security Pair.’ stage. You need to change permission to 600.
sudo chmod 600 ~/.ssh/name.pem
or you gonna see this error message.
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: UNPROTECTED PRIVATE KEY FILE! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
I’m using mac. To connect to the server.
ssh -l ubuntu -i ~/.ssh/name.pem YOUR_PUBLIC_SERVER_ADDRESS
Got it!
