nginx same port proxy problem

Question

Background: For security reasons, the customer only allows the external server to open port 80. The system we deployed includes an IM module using the xmpp protocol. So there are the following questions.

The following is the access log of nginx:

192.168.1.113 - - [19/Mar/2015:17:08:42 +0800] "<?xml version=1.0\x22?>" 400 172 "-" "-"
192.168.1.113 - - [19/Mar/2015:17:08:46 +0800] "<?xml version=1.0\x22?>" 400 172 "-" "-"

Excuse me: How to write the nginx configuration file?

192.168.1.113 - - [19/Mar/2015:17:08:46 +0800] "POST /login HTTP/1.1" 400 172 "-" "-"

Answer 1

nginx does not support the XMPP protocol. You can use BOSH, but it requires client support.

You can also write an nginx module to forward to the backend XMPP server when the request is XML. Of course, another solution is to add a code program written by yourself in front of nginx. Please transfer it to nginx or XMPP.

Answer 2

Why only open port 80? Even if it is forwarded by nginx... doesn't it also directly access XMPP? Does nginx do any authentication verification?

In addition, nginx supports tcp proxy
