So far the only way of creating a highly available cluster with a floating IP approach was using bare metal serves in any datacentre, until Digital Ocean arrived. As far as I know, Digital Ocean is the only VPS datacentre who provides floating IP services. Floating IP is very handy, it is the key to create a highly available cluster by moving a floating IP under demand among some selected servers.

I have already explained how to configure a FreeSWITCH HA Cluster. In this article, I will only explain how to configure the Digital Ocean's Pacemaker resource.

Today I have published in OKay's RPM repository RPMs for TXT2PDF. This is a Python 2 / 3 script using the ReportLab module for generating PDF documents. It is intended to be used with monospace True Type fonts. It can be hacked for being used with Type 1 Postscript fonts, but such fonts contain fewer characters than TTF ones.RPM's are available for Centos 6 and 7. And you can find it if you type yum search txt2pdf.

Enjoy!
