Hi Cyrus
Here is the simple keepalived configuration we're using.
It serves us very well for redundancy of the web GUI.
All you need is “apt install keepalived” on every cluster node and the
configuration in /etc/keepalived/keepalived.conf.
Just mind the different priorities - gory details in the keepalived.conf(1) man
page.
The browser title page will show you which node you are actually connected to.
