Setup HAproxy on an Uberspace webspace

HAproxy als Reverse Proxy auf Uberspace installieren

Wer bei verschiedenen Reverse Proxy Aktivitäten auf seinem Uberspace mit Apache auf Grenzen stößt, kann HAproxy installieren. Ähnlich wie Pound ist es DASein Swiss Army Knife für alle HTTP, HTTPS und TCP Aktivitäten. Man kann sehr granular auf Layer 3-7 beeinflussen, wie Daten an andere Server und Dienste weitergeschleust werden sollen.

Ich benötigte HAproxy, um eine Website von einem externen Server via TLS gesichert per Uberspace verfügbar zu machen, also ein recht simles Szenario.

Apache Proxy einrichten
