Using Redis + Sentinel HAProxy RHEL 6

Here are some of my notes.

sudo yum install -y mock
sudo useradd -s /sbin/nologin mockbuild
wget http://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/os/SRPMS/haproxy-1.5.4-3.el6.src.rpm
sudo mock -r epel-6-x86_64 haproxy-1.5.4-3.el6.src.rpm
cd /var/lib/mock/epel-6-x86_64/result
sudo rpm -ivh haproxy-1.5.4-3.el6.x86_64.rpm
rpm -qa|grep haproxy

config

sudo vi /etc/haproxy/haproxy.cfg
