This snippets shows you how to add an ssl backend to HAPROXY. You need haproxy 1.5 or higher, 1.4 does not support ssl backends.
This snippet is tested on a Digital Ocean VPS. If you like this snippet and want to support me, use this link to order a Digital Ocean VPS: https://www.digitalocean.com/?refcode=7435ae6b8212
Note: this is not about adding ssl to a frontend. this allows you to use an ssl enabled website as backend for haproxy.
The following config is required in a
backend example-backend balance roundrobin option httpchk GET /health_check server srv01 10.20.30.40:443 weight 1 maxconn 100 check ssl verify none server srv02 10.20.30.41:443 weight 1 maxconn 100 check ssl verify none
The important parts are:
10.20.30.41:443 ssl verify none
You can also specify verify all. As expected, this will verify all certificates, however this will generate extra load. For this example setup the
verify none is good enough.
