Introduction
This article explains how to create a MySQL8.0 HA cluster using group replication and MySQL router. It is important to note that I am using an Ubuntu 20.04 LTS server edition as the LXC host OS and have created 4 Ubuntu 20.04 containers in it and installed MySQL 8.0 from the repositories. The containers have private IPs and they are not reachable on public network. A reverse proxy is setup on the LXC host server so that application setup on the containers are accessible on port 443 or port 80. It can be found here.
Basic preparation
Container details are mentioned below. Host entries have been made into respective servers so that the servers can reach every other server using a hostname instead of an IP.
| # | Container | Hostname | IP Address | Software installed |
|---|---|---|---|---|
| 1 | Container 1 | db1 | 10.0.3.202 | mysql server 8.0 |
| 2 | Container 2 | db2 | 10.0.3.246 | mysql server 8.0 |
| 3 | Container 3 | db3 | 10.0.3.175 | mysql server 8.0 |
| 4 | Container 4 | db4 | 10.0.3.100 | mysql server 8.0 |
| 5 | Container 5 | web1 | 10.0.3.33 | mysql-client, apache2, php7.4 |
