Community, I have spent a decent amount of time attempting to get KEYCLOAK
behind an NGINX Reverse Proxy to protect a TOMCAT Application. It does work
without the proxy, but I need the proxy to handle certificates. I think I
am pretty close to having it working, but somethings seems to be missing...
I have done the following. I appreciate any insight you may have as I think
I have exhausted other resources.
*1. Configure a server in NGINX*
server {
listen 443;
ssl on;
ssl_certificate /etc/ssl/certs/dcf30de94f28f16f.crt;
ssl_certificate_key /etc/ssl/certs/*.domain.key;
server_name sso2. domain.com;
access_log /var/log/nginx/nginx.sso.access.log;
error_log /var/log/nginx/nginx.sso.error.log;
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Port 443;
proxy_pass http://internalip:8080;
}
}
*2. Enable SSL on a Reverse Proxy*
First add proxy-address-forwarding and redirect-socket to the http-listener
element:
<subsystem xmlns="urn:jboss:domain:undertow:1.1">
...
<http-listener name="default" socket-binding="http"
proxy-address-forwarding="true" redirect-socket="proxy-https"/>
...
</subsystem>
Then add a new socket-binding element to the socket-binding-group element:
<socket-binding-group name="standard-sockets"
default-interface="public"
port-offset="${jboss.socket.binding.port-offset:0}">
...
<socket-binding name="proxy-https" port="443"/>
...
</socket-binding-group>
*RECIVE THE FOLLOWING ERROR in TOMCAT:*
