This installation is going to require 2 servers one acts as kerberos KDC server
and the other machine is going to be client. Lets assume the FQDN's are (here
cw.com is the domain name, make a note of the domain name here):
Important: Make sure that both systems have their hostnames properly set and both systems have the hostnames and IP addresses of both systems in

How to Ignore Merge Conflicts for Specific Files in a Git Repository
Create a directory and git init it
$ mkdir merge-test
$ cd merge-test/
$ git init
Generate a GPG Key and revocation cert per http://www.gnupg.org/gpg/en/manual.html:
gpg --key-gen
gpg --output revoke.asc --gen-revoke <my user ID or email>
Once gpg key in keyring we can encrypt and decrypt files.
| # Haproxy config file for SSL and basic authentication | |
| # | |
| # Since ssl is needed, we need to use | |
| # `make TARGET=linux26 USE_OPENSSL=1 ADDLIB=-lz` to install haproxy. | |
| # Also, haproxy version must be haproxy-1.5-dev19 or above. | |

| # An example curl command that queryies pic-collage.com/api/collages/feed is | |
| # `curl -k -v -u 'collages:password' 'https://ec2-ip.compute-1.amazonaws.com/api/collages/feed'` | |
