Re: Apache2 and Tomcat : Simultaneously running both servers and Virtual Hosting.

[William A Rowe Jr <wrowe@xxxxxxxxxxxxx>]

Pretty simple answer, you either,

1. Change the Tomcat port, E.g. 8080 so it doesn't collide with httpd, or

2. Listen (IPaddr1):80 to httpd and bind (IPaddr2):80 to Tomcat.

The second can be more confusing, since if you bind localhost:80 to Tomcat, httpd won't respond unless you make a request to its own IP listener.

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"

        <Host name="domain-first.com" autoDeploy="true" unpackWARs="true" appBase="tooltank_webapps">
                <Alias>www.domain-first.com</Alias>
                <Context path=""/>
        </Host>

        <Host name="domain-second.com" autoDeploy="true" unpackWARs="true" appBase="aupair_webapps">
                <Alias>www.domain-second.com</Alias>
                <Context path=""/>


    </Host>
    <Connector port="8010" protocol="AJP/1.3" redirectPort="443" URIEncoding="utf-8"
 compressableMimeType="text/html,text/xml,text/plain,text/css,text/ _javascript_,application/x-_javascript_,application/_javascript_"
/>

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..
