Setup redis-cli without the whole Redis Server on AWS EC2

This fast tutorial will teach you how to install redis-clion AWS EC2 without having to install the whole Redis Server. Firstly, SSH into your EC2 instance and run the following command:

$ sudo yum install gcc

This may return an "already installed" message, but that's OK. After that, just run:

$ wget http://download.redis.io/redis-stable.tar.gz && tar xvzf redis-stable.tar.gz && cd redis-stable && make && sudo cp src/redis-cli /usr/local/bin/ && sudo chmod 755 /usr/local/bin/redis-cli
