How to Configure and Use HAProxy for Load Balancing
Due to its way of working, HAProxy requires: CPU: prefer the speed and the cache size over the number of cores; enough memory to handle all the TCP connections + HAProxy + system * network interfaces: intel ones are usually a good choice I found another way to modify logging to be able to log the data I need. E.g. Configure in the frontend. log-format “${HAPROXY_HTTP_LOG_FMT} limit:%{+Q}[var([HOST])] agent:%{+Q}[var([HOST])] backend:%{+Q}[var([HOST])] path:%{+Q}[var([HOST])]” Then use the next statement in the frontend or the backend Eventually, we ended up with the following HAProxy configuration for our backend: http-request set-header Connection keep-alive. http-request set-header Host [HOST] http-request set-header X-Forwarded-Proto https. option httpchk GET /. http-check send hdr Host [HOST]
