Perform an update to ensure you've got the latest of everything in the base package.

Install wget so you can download a few things.

yum install wget

Allow yum to locate/install redis, per this page here.

wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm"

Now, install all the prerequisites

Enable and start MySQL

chkconfig --level 3 mysqld on

Secure your MySQL installation by setting a password. replace 'new-password' with your secure password.

mysqladmin -u root password 'new-password'
mysqladmin -u root -h YourHost.YourDomain.com password 'new-password'

Open up the necessary firewall ports

vi /etc/sysconfig/iptables
  copy this line.
    -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
  and add two more with port 80 & 443 as well
    -A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
    -A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT

Restart the firewall

service iptables restart
