Hi, this guide will show you how to setup OpenLiteSpeed as reverse proxy server.

In this example , I will use backend.cyberpanel.net as back-end , and reverse.cyberpanel.net as front-end.

  1. First of all , test both domains are working


  1. Now go to External App , create a new external app type “Web Server”

  1. Let’s call it “Backend” , this name will be used in later step.

In this case , it’s same machine , so it is 127.0.0.1 , if it’s different server , you can set public IP , if backend is HTTPS , remember add https://

  1. Now create a context, type “Proxy”, set URI to /

  1. Since it’s different domain , you also have to pass hostname for backend to accept request.

RewriteRule ^/(.*)$ http://backend/$1 [P,E=Proxy-Host:backend.cyberpanel.net]`

note: backend is the name you created in step 3, and backend.cyberpanel.net is our back-end domain.

  1. Now let’s restart OpenLiteSpeed and test it.

what do you mean ? proxy to 2 servers on same domain , like load balancer ?

14

15

so should i setting it through OpenLiteSpeed webadmin console, right? or it can be done through cyberpanel?

If you want to reverse proxy something, you have to set it up in Webadmin

Query -

In this case where SSL will install?

On apache or openlitespeed ?

you can install on both place if you want to communication between OLS and Apache to be HTTPS

otherwise , on OLS , as it faces in front

One more issue - How to put OLS in front for apache? When we do apache not starting and always getting error like

(98)Address already in use: AH00072: make_sock: could not bind to address [::]:82

I checked many times this port is not in use but still error comping and apache not starting.

Tried putting
sudo setenforce 0

But no luck.

you need to confirm the port with netstat command
if you server doesn’t have ipv6 , then you need to comment out ipv6 bind
