Haproxy
Most important: continuously check ssllabs
Most important: continuously check to ensure ssllabs gives A+ rating for all sites.
It's important to get a current cipher configuration right.
SSL cert format
Haproxy wants a combined PEM format, with crt and keys included. Typical way:
cat STAR_equityshift_io.crt > manual_combined.pem cat equityshift_io.key >> manual_combined.pem
Config
For working code to get an A+, work on the config, here:
đ” m@bitpost [~/development/scripts/gentoo/bitpost/root] emacs haproxy.cfg
It contains a list of all my sites that are currently live.
After changing it, restart it:
sudo /etc/init.d/haproxy restart
2019-12-08 It was updated to use a new config format to prevent ssl less than TLS1.2. It was also updated with an attempt to redirect www.* to *, but we need updated certificates with multiple names. certbot script was updated to add them, but it has not recreated certs yet. Check back in February at the latest!
