Hi,
I'm trying to configure reverse proxy rules in vhost.conf. I have
Apache-2.2.8 on Ubuntu-8.04 (monitored by Plesk-10.4.4).
What I'm trying to achieve is defining a reverse proxy rule that defers
all traffic to -say- <http://mydomain/tomcat/> to the Tomcat server
running on port 8080. I have mod_rewrite and mod_proxy loaded in Apache.
As far as I understand mod_proxy docs, entering following rules in a
vhost.conf file should work:
| <Proxy *>
Order deny,allow
Allow from all
</Proxy>
|
| ProxyRequests off
RewriteRule ^/tomcat/(.*)$ http://mydomain:8080/$1 [P]
|
(Note: I tested with a RewriteRule directive to get at least some
logging.) Yet, I am getting a HTTP 500: internal server error when
requesting above URL.
I have made mod_rewrite log extensively, and find following entries in
the logs:
81.241.230.23 - - [19/Mar/2012:16:42:59 +0100]
[mydomain/sid#b06ab8][rid#1024af8/initial] (2) init rewrite engine with
requested uri /tomcat/testApp/
81.241.230.23 - - [19/Mar/2012:16:42:59 +0100]
[mydomain/sid#b06ab8][rid#1024af8/initial] (3) applying pattern
'^/tomcat/(.*)$' to uri '/tomcat/testApp/'
81.241.230.23 - - [19/Mar/2012:16:42:59 +0100]
[mydomain/sid#b06ab8][rid#1024af8/initial] (2) rewrite '/tomcat/testApp/' ->
'http://mydomain:8080/testApp/'
81.241.230.23 - - [19/Mar/2012:16:42:59 +0100]
[mydomain/sid#b06ab8][rid#1024af8/initial] (2) forcing proxy-throughput with
http://mydomain:8080/testApp/
81.241.230.23 - - [19/Mar/2012:16:42:59 +0100]
[mydomain/sid#b06ab8][rid#1024af8/initial] (1) go-ahead with proxy request
proxy:http://mydomain:8080/testApp/ [OK]
This suggests that the rewrite and proxy part are processed ok; still
the proxied request produces a 500 error. Addressing the testApp
directly via <http://mydomain:8080/testApp> does work, and the same
setup does work on my local computer.
Does anyone have an idea what might be wrong, or how I at least can get
more useful information than 'internal server error' (apart from above
rewrite logs, I can't find any trace of this request in other logs).
Any pointers much appreciated!
