Re: Tomcat, Apache web-server : Simultaneously running both servers and Virtual Hosting.

[Kernel freak]

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

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 :








  
 
 www.domain-first.com
 
 

 
 www.domain-second.com
 


 
 



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:

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..



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  
scheme, together with mod_rewrite, mod_proxy etc..

Re: Tomcat, Apache web-server : Simultaneously running both servers and Virtual Hosting.

[Kernel freak]

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 :

So you don't know what mistake I am making in the configuration?

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,

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)  :-)

Re: URL based redirection working partially with Apache tomcat

[Kernel freak]

Hi Chris,

I was able to finally resolve it by adding Host elements directly in
server.xml and creating separate webapps folder for each app to hold the
WAR file. I am on to a bigger fish. I will post a question soon in mailing
list. Thank you.

Tomcat, Apache web-server : Simultaneously running both servers and Virtual Hosting.

[Kernel freak]

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 :








 

www.domain-first.com




www.domain-second.com








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..

[ANN] Apache Tomcat 8.0.30 available

[Mark Thomas]

The Apache Tomcat team announces the immediate availability of Apache
Tomcat 8.0.30.

Apache Tomcat 8 is an open source software implementation of the Java
Servlet, JavaServer Pages, Java Unified Expression Language and Java
WebSocket technologies.

Apache Tomcat 8.0.30 includes fixes for issues identified in 8.0.29 as
well as other enhancements and changes. The notable changes since 8.0.29
include:

- Location headers for redirects now use relative URIs. This can
  be controlled by Context with the useRelativeRedirects attribute.

- Correct a regression in 8.0.29 that broke redirects for context
  roots.

- Restore the default setting of quoteAttributeEL in Jasper to true
  to align with 8.0.26/7.0.64 and earlier as well as other JSP
  implementations.


Please refer to the change log for the complete list of changes:
http://tomcat.apache.org/tomcat-8.0-doc/changelog.html

Downloads:

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

> [] Restarting web server: apache2(98)Address already in use:

... 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  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.)
