Tomcat, Apache web-server : Simultaneously running both servers and
Virtual Hosting.
Hello friends,
I am working on some server side changes in which I have the webapps or
website hosted by Apache server is called by the URL. So if url is
www.domain-one.com, then the specific webapp or website must be served.
I have partial success in these regards as I have already configured Apache
Tomcat to host multiple webapps, and call them based on URL. It is working.
Now on to the 2nd stage of problem, where I have hosted a CMS on Apache
server, and would like to call it with a URL, *but also keep Apache tomcat
running in parallel*, and this is the main problem I am dealing with.
This may seem like a Apache server issue, but it's both, as I want to run
Apache web-server and Apache tomcat simultaneously with Virtual hosting. I
just hope there might be people here who know both servers.
I tried mod_jk without any luck. Here are the changes I made to tomcat and
apache server.
Tomcat changes : server.xml :
<Connector port="80"
protocol="org.apache.coyote.http11.Http11NioProtocol"
compression="force" compressionMinSize="1024"
connectionTimeout="20000" maxPostSize="5242880"

URIEncoding="utf-8"
compressableMimeType="text/html,text/xml,text/plain,text/css,text/

/>
Installed mod_jk with following command :
apt-get install libapache2-mod-jk
Created file workers.properties in /etc/apache2/
# Define 1 real worker using ajp13
worker.list=worker
# Set properties for worker (ajp13)
worker.worker.type=ajp13
worker.worker.host=localhost
worker.worker.port=8010
Instructed jk.conf to load this file :
JkWorkersFile /etc/apache2/workers.properties
Finally edited 000-default in sites-enabled to add :
JkMount /home/user/tomcat_directory/* worker1
Then restarted Apache2, and I got this error :
[....] Restarting web server: apache2(98)Address already in use:
make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
Action 'start' failed.
The Apache error log may have more information.
failed!
I understand that Tomcat is running on 80, but how do I then configure
the servers so they can run simultaneously.
Kindly let me know..

Akshay S.

Hi,
Thank you for the links, I will go through it. I have configured Apache
Tomcat to serve multiple webapps depending upon the URL, but Apache
web-server is what seems to be stopping me.
The major problem I am having is I cannot find any examples if someone has
tried to do this before. I have gone a bit further since I posted the
question in the mailing list. Can you please check out this question :
http://serverfault.com/questions/740534/apache-webserver-tomcat-runing-multiple-tomcat-webapps-and-apache-webserver
Thanks a lot. Now my only-problem is how to inform Apache2 that, don't
process this URL, just forward it. I will read it in parallel what you
gave.
Regards,
Akshay S

Hi. You may have a lot of reading to do, specially on the Apache httpd side.
It will be worth it in the end, to be able to think "globally" about the issues, and to be
able to decide where best to do what.
1) Virtual Hosts :
http://httpd.apache.org/docs/2.2/vhosts/ --> name-based virtual hosts
2) Proxying from Apache to Tomcat :
http://httpd.apache.org/docs/2.2/mod/mod_proxy.html
http://httpd.apache.org/docs/2.2/mod/mod_proxy_ajp.html (an alternative to mod_jk)
.. and mod_jk you already know
3) URL Rewriting :
http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html
(allows you to do a lot of things, in combination with mod_proxy, but at a much finer
level)
Also, a tip if you want to use mod_jk in combination with all the Apache-httpd modules
above : look at an alternative way to configure proxying from httpd to Tomcat, here :
http://tomcat.apache.org/connectors-doc/reference/apache.html
section : Using SetHandler and Environment Variables
This method replaces the JkMount/JkUnMount, and fits nicely in Apache httpd's <Location>
scheme, together with mod_rewrite, mod_proxy etc..

Hi Chris,
I just saw your mail, although I was able to solve this problem yesterday
before leaving. This is what I did. I just waned to know, if this
configuration will also work if I am using https. Thank you.
Here is what I did :
Tomcat's server.xml :
<Connector port="8080" proxyPort="80" redirectPort="443"
protocol="HTTP/1.1" compression="force" compressionMinSize="1024"
connectionTimeout="20000" maxPostSize="5242880"
URIEncoding="utf-8"

javascript,application/x-javascript,application/javascript"/>
<Connector port="443"

maxPostSize="5242880" SSLEnabled="true" maxThreads="200" compr$
compressionMinSize="1024" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS"
keystoreFile="keystore.jks" keystorePass="PASSWORD"

<Connector port="8010" protocol="AJP/1.3" redirectPort="80"
URIEncoding="utf-8"
compressableMimeType="text/html,text/xml,text/plain,text/css,text/
javascript,application/x-javascript,application/javascript"
/>
<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat">
// Multiple webapps hosted
</Engine>
Added this in jk.conf :
<IfModule jk_module>
JkWorkersFile /PATH/to/workers.properties
JkLogFile /var/log/apache2/mod_jk.log
JkLogLevel notice
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions +ForwardURIProxy
JkMountFile /path/to/uriworkermap.properties
</IfModule>
workers.properties :
worker.list = worker_app1
worker.worker_app1.type = lb
worker.worker_app1.balance_workers = app1_instance1
worker.worker_app1.sticky_session = true
worker.worker_app1.sticky_session_force = false
worker.worker_app1.method = busyness
worker.app1_instance1.type = ajp13
worker.app1_instance1.host = 127.0.0.1
worker.app1_instance1.port = 8010
worker.app1_instance1.host = localhost
worker.app1_instance1.lbfactor = 1
worker.app1_instance1.socket_timeout = 40
worker.app1_instance1.socket_keepalive = true
worker.app1_instance1.reply_timeout = 30000
uriworkermap.properties :
/|/* = worker_app1;
Added this to 000-default in sites-enabled
// This is the tomcat domain.
<VirtualHost *:80>
ServerName www.domain_tomcat_webapp.de
ServerAlias domain_tomcat_webapp.de
ProxyRequests on
ProxyPreserveHost On

</Proxy>
ProxyPass / http://localhost:8080/
ProxyPassReverse / http://localhost:8080/
<Location / >
Order allow,deny

</Location>
</VirtualHost>
Will this config also work if the the request made is in https? Kindly
let me know. Thanks a lot. :-)

You have configured Tomcat for ports 80 and 443. When you start httpd:

... you get a port conflict. You have to choose: httpd or Tomcat on port
80 (and 443).

It looks like you started configuring for mod_jk, but didn't really
finish. What you have to do is proxy *all* applications from http ->
Tomcat. Then remove the HTTP <Connectors> from Tomcat and rely
exclusively on the AJP connector(s). (You really only need one single
AJP connector, since it will forward TLS information across to Tomcat.)

Why would I? I don't have your server log to inspect. And I haven't
used mod_jk in a very long time, so I didn't even bother looking at
your config.
Also, FYI, Apache httpd has a built-in configuration checker that you
could (and apparently should) run (hint) :-)

To start, the information in the server log referenced above.
Secondly, I'd strongly recommend you start out by using plain old
mod_proxy and mod_proxy_http rather than mod_jk - less config
required, doesn't require changing your Tomcat config other than
picking a different port number than 80 for your connectors.
Good luck,

Thank you for the changes you suggested. First problem is, not all the
webapps have Https enabled, so I have to use port-number 80. Can you
suggest me an alternative configuration. I have changed it to port 8080 and
given a proxyPort=80 as follows :

workers.properties looks like :
worker.list = worker_app1
worker.worker_app1.type = lb
worker.worker_app1.balance_workers = app1_instance1
worker.worker_app1.sticky_session = true
worker.worker_app1.sticky_session_force = false

worker.app1_instance1.lbfactor = 1
worker.app1_instance1.socket_timeout = 40
worker.app1_instance1.socket_keepalive = true
worker.app1_instance1.reply_timeout = 30000
uriworkermap.properties looks like :
# Proxy everything to backend:
/|/* = worker_app1;
jk.conf in modules-enabled
<IfModule jk_module>
JkWorkersFile /etc/apache2/workrs.properties
JkLogFile /var/log/apache2/mod_jk.log

After this, when I try to open domain_tomcat.de, I get :
The server encountered an internal error or misconfiguration and was unable
to complete your request.
Please contact the server administrator, [no address given] and inform them
of the time the error occurred, and anything you might have done that may
have caused the error.
More information about this error may be available in the server error log.
So, what am I missing. Kindly let me know. Thanks a lot. :-)
