Setup redis-cli on AWS EC2

SSH into your EC2 instance. Run the following:

$ sudo yum install gcc This may return an "already installed" message. That's OK.

$ wget http://download.redis.io/redis-stable.tar.gz && tar xvzf redis-stable.tar.gz && cd redis-stable && make

See: http://docs.aws.amazon.com/AmazonElastiCache/latest/UserGuide/GettingStarted.ConnectToCacheNode.Redis.html

# The command finds the most recent tag that is reachable from a commit.
# If the tag points to the commit, then only the tag is shown.
# Otherwise, it suffixes the tag name with the number of additional commits on top of the tagged object 
# and the abbreviated object name of the most recent commit.
git describe

# With --abbrev set to 0, the command can be used to find the closest tagname without any suffix:
git describe --abbrev=0
