Overview
Concepts:
The default configuration file /etc/haproxy/haproxy.cfg.
Frontend Configuration
Frontend binds on both 80 and 443 to allow both regular and SSL HTTP requests.
frontend localhost bind *:80 bind *:443 option tcplog mode tcp default_backend nodes
Frontend iptables Considerations
If the host HAProxy is deployed on runs iptables, access to ports 80 and 443 has to be explicitly open as follows:
-A INPUT -p tcp -m tcp --dport 80 -m state --state NEW -j ACCEPT -A INPUT -p tcp -m tcp --dport 443 -m state --state NEW -j ACCEPT
For more details see iptables - Allow a Web Server on a Specific Interface.
Backend Configuration
Backend also needs to be set in "tcp" mode.
backend nodes mode tcp balance roundrobin option ssl-hello-chk server node01 192.168.1.11:443 check server node02 192.168.1.12:443 check
Alternatively, "balance source" can be used.
Backend iptables Considerations
If the backend hosts run iptables, they must be configured to allow new connections on port 443:
-A INPUT -p tcp -m tcp --dport 443 -m state --state NEW -j ACCEPT
For more details see iptables - Allow a Web Server on a Specific Interface.
