haproxy SNI configuration with SSL pass through

This comes from this forum post and adapted with info from this gist

A sample HAproxy configuration using SNI. Using SNI has the advantage that you don't have to mess with the certificates on the HAproxy server itself. Useful with many servers and / or many fast-expiring certificates (letsencrypt).

For best results:

  • Use only a single core per VM (cpus setting). This is critical, more causes problems.
  • Set the sysctl.conf settings below

Configure sysctl.conf and reboot

Add to /etc/sysctl.conf and reboot
