AWS-RHEL

#Setup and launch an RHEL EC2 instance
#Ensure that the security group (firewall) allows access to port 8787

#Login via SSH
#Guide: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AccessingInstancesLinux.html
ssh -i keyfile.pem ec2-user@ec2-11-22-33-44.compute-1.amazonaws.com

#Keyfile.pem is the name of your the keyfile you generated with AWS.
#RHEL users are either root or ec2-user
#ec2-11-22-33-44.compute-1.amazonaws.com is the "actuall" public name assigned by AWS

sudo su

#Install R (not using su or sudo from site, instead using the line above):
#Guide: http://www.jason-french.com/blog/2013/03/11/installing-r-in-linux/
rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
#yum update #Not sure I like this step… Adds way more than I want/need… 
yum install R

Ultimately, need to save this as a corporate approved AMI so that it doesn’t need to be recreated every time!

#Install R Studio Server
wget http://download2.rstudio.org/rstudio-server-0.98.1060-x86_64.rpm
sudo yum install --nogpgcheck rstudio-server-0.98.1060-x86_64.rpm

#Add a username and password so that someone can login to the server.
useradd uname
passwd uname

#Access the server using the public name and the port 8787.
