Hi,

I'm trying to create a reverse proxy on Rackspace with nginx and tomcat.

Rackspace servers have two ethernet adapters eth0 (public internet, public ip address) and eth1 (private Rackspace network, private ip address, no bandwidth costs).

I can't get my nginx webserver to connect to the appserver over the local ip address. I keep getting a timeout. I'm thinking, not sure, that nginx is trying to route the reverse proxy request over the eth0 when it should be routing it over eth1.

Can you give me any suggestions on how to configure for this?

Kind regards,

Marc

I'm trying to use proxy_bind but it doesn't work.

I have
[b]Web server nginx[/b]
eth0
private ip: 2.2.2.200

eth1
public/internet ip: 1.1.1.200

[b]App server tomcat[/b]
eth0
private ip: 2.2.2.100

eth1
public ip: 1.1.1.100


My nginx config is like so
[code]

nginx.conf
http {
upstream msa {
server 2.2.2.100:8080;
}
[...]

site config
[...]
location @proxy {
auth_basic "Restricted";
auth_basic_user_file /usr/local/etc/passwords;


proxy_buffering on;
proxy_bind 2.2.2.100;
proxy_cache STATIC;
proxy_pass http://msa;
proxy_cache_valid 200 15m;
proxy_cache_valid 404 5m;
proxy_cache_use_stale error timeout invalid_header updating
http_500 http_502 http_503 http_504;
proxy_cache_key $host$request_uri;
proxy_ignore_headers Set-Cookie;
proxy_cache_bypass $proxy_bypass;


proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
#proxy_max_temp_file_size 0;
#proxy_store off;

proxy_connect_timeout 30;
proxy_send_timeout 30;
proxy_read_timeout 30;

}

[/code]

I'm seeing these kinds of errors
2011/02/07 18:30:20 [error] 4907#0: *1 connect() failed (110: Connection timed out) while connecting to upstream, client: 201.83.48.178, server: _, request: "GET / HTTP/1.1", upstream: "http://2.2.2.100:8080/", host: "1.1.1.200"

I would expect a connect of upstream: http://2.2.2.100:8080, host 2.2.2.200

The whole set up does work when I run it across eth1, the default. It seems like the proxy_bind command is ignored. I have nginx 0.8.54 based on Brian's distro.

Please help.

Kind regards,

MArc

Sorry, I made a typo in the config for the example.
proxy_bind 2.2.2.100

Come on guys, some help or suggestions please

Kind regards,
Marc

Ok, resolved, running tcpdump on eth1 showed me a stupid configuration error on my side
