Is there a GOOD AJP-based cluster reference?
I've googled and not found anything very helpful, particularly nothing
recent.
I am trying to set up AJP load balancing using Apache 2.2.17 to Tomcat
6.0.29.
I'd like to route root to the Tomcat named context (not root). From the
docs I've read so far, I should be able to, but all the references in
the returned html have the context name stuck at the beginning of the
path, and I can't seem to get it to go away.
I know I can just rename the context as ROOT, but I thought I'd try
deploying it the way the dev team gives it to me.
I've tried:
ProxyPass / balancer://mycluster/context
<Proxy balancer=//mycluster>
BalancerMember ajp://hostname:8009
</Proxy>
and
ProxyPass / balancer://mycluster
<Proxy balancer=//mycluster>
BalancerMember ajp://hostname:8009/context
</Proxy>
Nothing seems to be working. Obviously, I'm not clear on some concept.
Any help would be appreciated.
Jeff
p.s. Don't send me to the Tomcat & Apache docs, I've read them.

Check the value of the path attribute, in Set-Cookie: header when a
session is created.

Some things are collected at
http://tomcat.apache.org/connectors-doc/generic_howto/proxy.html#URL%20Rewriting
Don't overlook the pointers for mod_proxy_html, mod_substitute and mod_sed.
Most of the steps are simplified by mod_proxy using ProxyPass,
ProxyPassReverse and ProxyPassReverseCookiePath, all documented at
http://httpd.apache.org/docs/2.2/mod/mod_proxy.html
If the response content contains URLs to fix and you can't get them
fixed on the webapp side, then mod_substitue, mod_proxy_html or mod_sed
can help changing the content on the fly. Of course this can get tedious
if the links in the content are hard to find (and also needs some CPU
resources).

Interesting.
I'll have to try something similar for my situation.
What I'm trying to do is a bit of the reverse. I want
hostname:80/tomcat-host/manager to end up at (tomcat-host) /manager for four
different tomcat hosts. The forward stuff works fine, but the URLs coming back
all drop the tomcat-host part.
I guess reading some more documentation is in order.
Glad you got it working without the reversproxy stuff.

In looking at the JSPs, the dev team is coding all the paths inside a
<c:url> construct, which is why the context string is getting prepended
to every path in the document. What was throwing me off a bit was the
default doc was just a redirect as:
------------------------------------------------------
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<% response.sendRedirect("login"); %>
------------------------------------------------------
The browser would show this as http://hostname/context/login. My
interpretation of the docs had me thinking that the context would get
stripped as well, but it wasn't. Thus the confusion.
I have managed to get it working with the following:
<Proxy balancer://mycluster>
BalancerMember ajp://prtltest01:8009/Portal route=tomcat1
loadfactor=50
BalancerMember ajp://prtltest02:8009/Portal route=tomcat2
loadfactor=50
</Proxy>
ProxyPass /Portal/static !
ProxyPass /Portal balancer://mycluster
stickysession=JSESSIONID|jsessionid scolonpathdelim=On
ProxyPass / balancer://mycluster/ stickysession=JSESSIONID|jsessionid
scolonpathdelim=On
Notice I don't have any ProxyPassReverse lines. From reading the docs,
I'm not sure they are needed for AJP proxying.
I'm trying to keep the Tomcat side of things fairly simple -- pretty
much deploy the war direct from dev -- to keep there from being too many
steps that could get screwed up when I'm not around and someone else
needs to deploy. The process will be documented, but some people refuse
to read directions correctly.
Plus, the apache server will someday host multiple apps under one host,
so having it work with the context as non-root now means less work
later. Then again, I bf'ed and didn't put the static stuff in the
proper tree structure under the htdocs dir. I just put them there as I
got them. (There is no "static" directory on the Tomcat side, it's
virtual. The dev team is doing weird stuff with this new product.)
Let me know if you see any problems with the above config.

Re: Is there a GOOD AJP-based cluster reference?
Posted by Mark Eggers <it...@yahoo.com>.
At the risk of violating your request (not to point you to the documentation),
I'm going to point you at the documentation.
In particular: manual/mod/mod_proxy.html#proxypassreverse (from the Apache httpd
docs)
This will rewrite response URLs. However, there is a caveat. It will not rewrite
any absolute URLs within the documents served. So if you have
/context/somewhere/someplace inside a particular page, this link will be
returned intact and the user will not be able to reach it. Again according to
the document, you'll need to look at Nick Kew's mod_proxy_html
(http://apache.webthing.com/mod_proxy_html/). There appears to be a tutorial on
reverse proxying at that location as well.
You may find it far easier to just rename the war file to ROOT.war and be done
with it.
. . . . just my two cents

That's what I'm doing now Pid.
Not sure if that's helping much since it seemed to work the other way
round also. Switching the order still showed the same apparent
behavior.
See my response to Mark Eggers about how I've got it working right now.
I'd love to get any more input from you if there is an issue on that
configuration.

What happens if you define the balancer before you try to use it?
