Building a small cluster

The goal of this page is to help you set up a small cluster of your own using Centos7.

Note: You will notice the packages are el6 this is because as of this writing we only build for Centos6.

Installing Talaria

In this example I'm using talaria version 0.1.1-244.

Add GPG Signature

sudo rpm --import https://github.com/Comcast/talaria/releases/download/0.1.1-244/RPM-GPG-KEY-comcast-xmidt

Install the Talaria RPM

sudo rpm --install https://github.com/Comcast/talaria/releases/download/0.1.1-244/talaria-0.1.1-244.el6.x86_64.rpm

Enable Talaria to Use ports < 1024

If you want to run Talaria on ports 443, 80 or other lower port numbers you need to tell Selinux to allow this executable to bind to them.

/usr/sbin/setcap CAP_NET_BIND_SERVICE=+eip /usr/bin/talaria
