HAProxyrawBest Practices
- Set explicit timeouts in defaults (timeout connect 5s, timeout client 30s, timeout server 30s, timeout http-request 10s)
- Enable health checks on all backend servers with check, inter, fall, and rise parameters
- Configure logging via syslog (log /dev/log local0) and use option httplog for HTTP traffic
- Use SSL/TLS termination with strong cipher suites and ssl-default-bind-options no-sslv3 no-tlsv10 no-tlsv11
- Use ACLs (hdr, path_beg, path_end, src) for intelligent request routing instead of multiple frontends
- Enable stats page with authentication (stats auth user:password) for monitoring
- Set global maxconn and per-frontend/backend maxconn to prevent resource exhaustion
- Use balance algorithms appropriate to workload (roundrobin for stateless, leastconn for varied response times, source for sticky)
