[SOLVED] Apache + Tomcat and virtualhosting

neosk_ · 02-01-2012, 09:15 AM

Hello everybody,

Am struggling with this issue for 2 days already and none of the documentation I found on the web helps me.

I am running Debian Squeeze, Apache 2, Tomcat 6

on http://10.0.0.1:8080 I get the Tomcat welcome page, on /manager I have succesfully deployed my .war application which now runs on http://10.0.0.1:8080/time - flawlessly

installation of tomcat6 was done by apt-get install tomcat6, have installed mod_jk into apache, apache still serves everything (including php pages)

ajp13 runs and listens on port 8009 (default)

what I now want is to have
http://time.domain.local get the data from http://10.0.0.1:8080/time

And I can't get it to run. My configs are following:

apache vhost file:

Code:

<VirtualHost time.domain.local:80>
     ServerName time.domain.local
     JkLogFile "/var/log/apache2/mod_jk-time.log"
     JkLogLevel debug
     JkMount /time default
     DocumentRoot /var/www/time.domain.local
</VirtualHost>

jk.conf (enabled)

Code:

<IfModule mod_jk.c>
  JkWorkersFile /etc/apache2/workers.properties
  JkShmFile /var/log/apache2/mod_jk.shm
  JkLogFile /var/log/apache2/mod_jk.log
  JkLogLevel info
  JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
  JkRequestLogFormat "%w %V %T"
</IfModule>

tomcat host chunk in server.xml; ajp13 listener enabled aswell:

Code:

      <Host name="time.domain.local" debug="0" appBase="time"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false">
        <Context path="/time" docBase="webapps/time"/>
      </Host>

application is located in
/var/lib/tomcat6/webapps/time/
- contains META-INF etc (well, it runs, so it should be working)

some .html pages and .php pages are in /var/www/time.domain.local

tomcat6/Catalina contains time/manager.xml which was auto-created probbably

in the apache vhost document root I have created also test.jsp, which is not being parsed for whatever reason
index.html or test.php are served flawleslly/parsed from apache vhost docroot

last lines of mod_jk-time.log:

Code:

Am clueless, drank a lot of koffee and on the edge of my sanity

please help

PS: I am no jsp programmer and this is my first time of Tomcat deployment

All this in a virtual machine ? Is that right? And you want to access this from outside like from internet?

yes, it's a virtual machine and no, it should be accessible only in an intern network
domain name is correctly set-up and also the DNS Entry is correct. Aswell as /etc/hosts contains correct information (i.e. time.domain.local pointing to 10.0.0.1).

Hi,

Quote:

JkMount /time default

Are you sure the worker name is default? You should use the name as it's defined in workers.properties (usually worker1, tomcat or ajp13). Search for the line "worket.list=..." to see what the actual worker name is.
Also try to add more JkMounts:

Code:

JkMount /time/* <worker name>
JkMount /*/time/* <worker name>

Regards

my workers.properties file:

Code:

workers.tomcat_home=/var/lib/tomcat6
workers.java_home=/usr/lib/jvm/java-6-sun
ps=/
worker.list=default
worker.default.port=8009
worker.default.host=localhost
worker.default.type=ajp13
worker.default.lbfactor=1

Also, I have added your suggestion to the vhost apache definition file
when I go to time.domain.local I get only directory listing with test.jsp and test.php, no content from Tomcat

What happens if you click on test.jsp?
If you want to serve jsp pages also from your docroot, you can add:

Code:

JkMount /*.jsp default

Also since you have only one worker, you don't need "worker.default.lbfactor=1", so comment it out. Then better restart tomcat first and then apache.

after clicking now I get

Code:

<html>
<head>
<title>JSP Test Page</title>
</head>
<body>

<h1>JSP Test</h1>

<%
// for(int c = 1; c < 10; c++) {
//   out.println("<P>Iteration " + c + "</P>");
// }
%>

</body>
</html>

after adding your line *.jsp default into vhost I get only a blank page (probbably some kind of error, I go check the logs now)

So apache matches /*.jsp and sends the request to the mod_jk default worker, but it gets an error 400 (Bad Request).
Move test.jsp in tomcat's webapps/ROOT directory and see if it works. Better clear your browser cache before visiting again test.jsp

did that, same result - blank page
but when I went to http://10.0.0.1:8080/test.jsp

the test page got rendered and served properly by Tomcat

Could you try proxy_ajp and see if it works. For this to work, you have to enable mod_proxy and mod_proxy_ajp in your apache configuration.

Then you need to comment out (or remove) any reference to mod_jk and inside your vhost use:

Code:

ProxyRequests Off
ProxyPass /time ajp://localhost:8009/time
ProxyPassReverse /time ajp://localhost:8009/time

neosk_ · 02-03-2012, 02:40 AM

Curiously enough apache logs do not report anything, is there some option how to see the logs from proxy_ajp and proxy ?
do I need some rewrite rules aswell in some htaccess in DocumentRoot?

the more I spend time on this the more I get disgusted with Java

bathory · 02-03-2012, 03:15 AM

Hi,

Quote:

<VirtualHost *:80>
ServerName time.domain.local
ErrorLog /var/log/apache2/time.domain.local-error.log
CustomLog /var/log/apache2/time.domain.local-access.log combined

ProxyPass /time ajp://localhost:8009/
ProxyPassReverse /time ajp://localhost:8009/
DocumentRoot /var/www/time.domain.local
</VirtualHost>

In the Proxy Pass directives above, you have to use the same URI where you have deployed your app. So change them both as in my previous post.
Regarding the logs, everything should be logged in the log files defined in your vhost (time.domain.local-access.log, time.domain.local-error.log)

neosk_ · 02-03-2012, 07:27 AM

Nope, does not work:

Code:

     ProxyRequests Off
     ProxyPass /time ajp://10.0.0.1:8009/
     ProxyPassReverse /time ajp://10.0.0.1:8009/

getting suicidal

Was also thinking already to do some with some rewrite engine, but aaaah
