In this series, we take you from bare-metal to a highly-available WordPress site, load-balanced over two nodes and resistant to VPS failures using MariaDB multi-master replication, DRBD, and round-robin DNS.
In this, the final episode of the series, we enable round-robin DNS and test our setup. What happens if we take down node #1? What about node taking down node #2? Does the user’s browser correctly switch nodes? Find out as we put our work to the test!
This video is based on our earlier tutorial.

Dread Lord of LowEnd Content at LowEndBox
I'm Andrew, techno polymath and long-time LowEndTalk community Administrator. My technical interests include all things Unix, perl, python, golang, shell scripting, vintage operating systems such as MVS, and relational database systems such as Oracle, PostgreSQL, and MySQL.
I also enjoy using LEBs! I have an empire of little guys for VPNs, larger guys for apps, and big guys for databases and storage. When I'm not in front a screen I'm into German Shepherd dogs, quality knives, target shooting, theology, tabletop roleplaying games, and forest hiking.
I enjoy writing technical articles here on LowEndBox to help people get more out of their systems. You can find me on LowEndTalk @raindog308
