This is a text-only version of the following page on https://raymii.org: --- Title : haproxy: ssl backends Author : Remy van Elst Date : 10-12-2013 URL : https://raymii.org/s/snippets/haproxy_ssl_backends.html Format : Markdown/HTML --- 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.

I'm developing an open source monitoring app called Leaf Node Monitoring, for windows, linux & android. Go check it out!

Consider sponsoring me on Github. It means the world to me if you show your appreciation and you'll help pay the server costs.

You can also sponsor me by getting a Digital Ocean VPS. With this referral link you'll get $100 credit for 60 days.

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` section: 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.
