Jboss 7, mod_cluster and PrettyFaces

[ssachtleben]

I want to provide a cluster of jboss as 7 behind mod_cluster 1.1.3.Final. First jboss runs on port 8088. My mod_cluster configuration is:

1. <IfModule manager_module>
2.   Listen 127.0.0.1:6666
3.   ManagerBalancerName mycluster
4.  
5.   <VirtualHost 127.0.0.1:6666> 
6.         KeepAliveTimeout 300
7.         MaxKeepAliveRequests 0
8.         AdvertiseFrequency 5
9.         ServerAdvertise On
10.  
11.     <Location />
12.         Order deny,allow
13.         Allow from All
14.     </Location>
15.   </VirtualHost>
16. </IfModule>
18. NameVirtualHost *:80
20. <VirtualHost *:80> 
21.     ServerAdmin [e-mail]
22.     ServerName Name
23.     ServerAlias www.domain.de www.domain.com
24.    
25.     ProxyPass / balancer://mycluster stickysession=JSESSIONID|jsessionid nofailover=On
26.     ProxyPassReverse / balancer://mycluster
27.  
28.     <Location />
29.         Order deny,allow
30.         Allow from All
31.     </Location>
32.  
33.     <Location /mod_cluster_manager>
34.        SetHandler mod_cluster-manager
35.        Order deny,allow
36.        Deny from all
37.        Allow from 127.0.0
38.     </Location>
39. </VirtualHost>

I have also some other vhosts to provide static access to my repository.

Now I have two problems:

1) The method getRemoteAddr() from HttpServletRequest returns the server ip instead of the client ip. How do I retrieve the client ip with mod_cluster?

2) The RewriteHandler from PrettyFaces (return MappingID on s:viewAction method invoke) redirects to http://www.domain.com//start.html. The getRequestURL() from HttpServletRequest says ttp://www.serverip:8088/start.html. Why occure double slashes with mod_cluster?

Both problems doesnt occure when I browse directly on jboss without mod_cluster.

Any help would be appreciated.

Hi Sebastian, let me look at #1:

1) The method getRemoteAddr() from HttpServletRequest returns the server ip instead of the client ip. How do I retrieve the client ip with mod_cluster?

You should look at what are you doing with that method, see javadoc:

http://download.oracle.com/javaee/1.4/api/javax/servlet/ServletRequest.html#getRemoteAddr%28%29

It clearly says:

Returns the Internet Protocol (IP) address of the client or last proxy that sent the request. For HTTP servlets, same as the value of the CGI variable REMOTE_ADDR.

This means you are geetting the IP of the proxy. So for the client you would need to look for a header similar to "x-forwarded-for" or so, not sure what the exact header is.

Thanks Radoslav. Sounds fair enough.

request.getHeader("x-forwarded-for") has the value

But still having the double slash problem...

[pferraro]

Let's see if Jean-Frederic has any insight into the double slash issue.

• ProxyPass / balancer://mycluster stickysession=JSESSIONID|jsessionid nofailover=On
• ProxyPassReverse / balancer://mycluster

Do you really need those mod_proxy directives? May be that is the problem.

As I said before I need several vhosts to provide static content and I just want the jboss cluster in one vhost. Here is my full configuration:

CreateBalancers 1

UseAlias 0

# MOD_CLUSTER_ADDS

# Adjust to you hostname and subnet.

<IfModule manager_module>

  Listen 127.0.0.1:6666

  ManagerBalancerName mycluster

  <VirtualHost 127.0.0.1:6666> 

           KeepAliveTimeout 300

          MaxKeepAliveRequests 0

          AdvertiseFrequency 5

          ServerAdvertise On

    <Location />

          Order deny,allow

          Allow from All

    </Location>

  </VirtualHost>

</IfModule>

NameVirtualHost *:80

<VirtualHost *:80> 

    ServerAdmin [e-mail]

    ServerName domain

    ServerAlias www.domain.de www.domain.com

    ProxyPass / balancer://mycluster stickysession=JSESSIONID|jsessionid nofailover=On

    ProxyPassReverse / balancer://mycluster

    <Location />

          Order deny,allow

          Allow from All

    </Location>

    <Location /mod_cluster_manager>

       SetHandler mod_cluster-manager

       Order deny,allow

       Deny from all

       Allow from 127.0.0

    </Location>

</VirtualHost>

<VirtualHost *:80>

          ServerAdmin [e-mail]

          ServerName static.domain.de

          ServerAlias static.domain.de

          ErrorLog "/PRODUCTION/mod_cluster-1.1.3.Final/httpd/logs/error.log"

          # Possible values include: debug, info, notice, warn, error, crit,

          # alert, emerg.

          LogLevel warn

          CustomLog "/PRODUCTION/mod_cluster-1.1.3.Final/httpd/logs/access.log" combined

</VirtualHost>

</VirtualHost>

I have tried to comment out ProxyPassReverse but then the redirect will be end in serverip:8088/requested.html (jboss port directly).

It seems like:

externalContext.redirect("/requested.html");

result in:

domain//requested.html

Any ideas?

[ssachtleben]

I have fixed it with changing configuration to:

ProxyPass / balancer://mycluster stickysession=JSESSIONID|jsessionid nofailover=On

ProxyPassReverse / balancer://mycluster

ProxyPreserveHost On

Now everything seems fine

[jfclere]

It seems the ProxyPassReverse / balancer://mycluster is creating the problem.

[ssachtleben]

Should I raise a jira issue?

I think it should work without ProxyPreserveHost also or am I wrong?

[jfclere]

I have created MODCLUSTER-250

Thanks!!!
