[root@localhost ~]# yum install puias-{addons,unsupported}
[root@localhost ~]# yum install rubygem-rubycas-server ruby-mysql mod_ssl mod_passenger mysql-server rubygem-net-ldap

Open /etc/sysconfig/iptables and allow port 443 (https) traffic:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT

Configure httpd:
[root@localhost ~]# chkconfig httpd on
[root@localhost ~]# rm -f /etc/httpd/conf.d/welcome.conf
Configure /etc/httpd/conf.d/ssl.conf to look something like this:

LoadModule ssl_module modules/
Listen 443

SSLPassPhraseDialog  builtin
SSLSessionCache         shmcb:/var/cache/mod_ssl/scache(512000)
SSLSessionCacheTimeout  300
SSLMutex default
SSLRandomSeed startup file:/dev/urandom  256
SSLRandomSeed connect builtin
SSLCryptoDevice builtin

Create a test cert and key for httpd - BE SURE TO REPLACE THESE IN PRODUCTION:
[root@localhost ~]# cd /etc/pki/tls/certs
[root@localhost ~]# make httpd.pem
[Fill out the questionaire]

Configure MySQL:
[root@localhost ~]# chkconfig mysqld on
[root@localhost ~]# service mysqld start
[root@localhost ~]# /usr/bin/mysql_secure_installation
Fill out the questions, be sure to set a new root password and remove all test accounts/dbs.
[root@localhost ~]# mysql -u root -p
mysql> create database casserver;
mysql> use casserver;
mysql> source /etc/rubycas-server/create_rubycas_mysql_db.sql

Create and configure the file /etc/rubycas-server/config.yml
There is an example config file located at /etc/rubycas-server/config.yml.example. Here is a trimmed example, all the helpful comments have been removed:

  pool: 10
  adapter: mysql
  database: casserver
  username: root
  password: CHANGEME
  host: localhost
  class: CASServer::Authenticators::LDAP
    port: 389
    base: dc=example,dc=com
    username_attribute: uid
    filter: (objectClass=person)
theme: simple
organization: CAS
infoline: Powered by <a href="">RubyCAS-Server</a>
default_locale: en
  file: /var/log/casserver.log
  level: INFO

At this point, you can test your implementation:
[root@localhost ~]# setenforce 0
[root@localhost ~]# service httpd start

Note that I disabled SELinux. This should be used only for testing purposes, to generate policy files.
Here is an example SELinux policy file that worked for me (but needs a serious cleanup):
