Installing the software

Install of the stuff you need, and maybe some of the stuff you don't.

yum install epel-release -y
yum install cobbler cobbler-web pykickstart fence-agents-all git nc dhcp xinetd

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

	# EG : ALTER USER Postgres WITH PASSWORD '<newpassword>';


	CP_PASS=`grep jpa.config.hibernate.connection.password /etc/candlepin/candlepin.conf \| awk -F= '{print $2}'`
	F_PASS=`grep password /etc/foreman/database.yml \| awk -F: '{print $2}' \| sed 's/"//g'`

	echo "ALTER USER candlepin WITH PASSWORD '$CP_PASS';" \| sudo -u postgres psql
	echo "ALTER USER foreman WITH PASSWORD '$F_PASS';" \| sudo -u postgres psql
