This works – Apache + Tomcat + mod_jk

This is a compact step-by-step guide for installing Tomcat with Apache and mod_jk on a Ubuntu 10.10 system considering following components

Apache 2, MySQL 5, PHP 5, PhpMyAdmin, Sun Java JDK 1.6, Tomcat 6.0, Tomcat-Admin, mod_jk

Important note: This is just the first version of this guide. It does not consider any previous configured or installed components

…Greyed out indicates should try, not tested…

Server setup would allow for skipping steps:

• 1 as we do not want MySQL on the same server and Apache2 is in setup (needs cleaned up)
• 2 as we do not care about PHP (and already skipping)
• 4 as we have it in the Setup

1 LAMP – Apache, MySQL, PHP (Add Tomcat)

Remember your MySQL password.

Now create a test page

$ sudo nano /var/www/info.php

and insert following code

Restart Apache

and check if everything went fine

2 PHPMyAdmin

Install via apt-get

Choose Apache, and insert credentials

Now create a soft-link to make phpmyadmin-sources available in /var/www

Now open a browser and see if it’s working

http://[MY_IP]/phpmyadmin

(use the credentials you defined shortly before)

3 JAVA

Due Sun’s java is not provided by the repository anymore, we have to add it manually:

Usually this should already be everything what we have to do. Try it by typing

4 TOMCAT – Commons and Admin/Manager

Install both tomcat-common and tomcat-admin via apt-get

For accessing the Tomcat-admin we need to add our own manager-user

And add the new user

Finally restart Tomcat

$ sudo /etc/init.d/tomcat6 restart

Try if it works

http://[MY_IP]:8080/manager/html

5 Mod JK

Install via apt-get

Now create our own workers.properties file for Apache.
Open or create

and paste:

and add following lines

Finally configure which URLs Apache should pass through the Tomcat

(If you want to pass all requests to the Apache (instead of individual ones), just remove the line
DocumentRoot /var/www
and add following JkMounts:
JkMount / worker1
JkMount /* worker1)

Serve some Java JSP Site called QBW-Web-Parent.com

$ sudo nano /etc/apache2/sites-available/QBW-Web-Parent.com

<VirtualHost *:80>
DocumentRoot /var/lib/tomcat6/webapps/QBW-Web-Parent
ServerName QBW-Web-Parent.com
JkMount /*.jsp worker1
JkMount /* worker1
</VirtualHost>
<VirtualHost *:443>
DocumentRoot /var/lib/tomcat6/webapps/QBW-Web-Parent
ServerName QBW-Web-Parent.com
JkMount /*.jsp worker1
JkMount /* worker1
SSLEngine On
# SSL Engine Switch:
# Enable/Disable SSL for this virtual host.
SSLEngine on
# A self-signed (snakeoil) certificate can be created by installing
# the ssl-cert package. See
# /usr/share/doc/apache2.2-common/README.Debian.gz for more info.
# If both key and certificate are stored in the same file, only the
# SSLCertificateFile directive is needed.
SSLCertificateFile /etc/ssl/certs/ssl-cert-snakeoil.pem
SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key
</VirtualHost>

=====================================================

And last but not least, we have to enable the redirect port 8443 on Tomcat

And uncomment / insert / update that following line is present

  </Host></Engine>

Now we only have to restart first the Tomcat and then the Apache

Et voila, now it should work as expected.

6 Setup a new virtual host in Apache2

Create the folders for our new virtual host:

mkdir /var/www/server1.example.com
mkdir /var/www/server1.example.com/htdocs
mkdir /var/www/server1.example.com/logs

Then create a new site in Apache2:

vi /etc/apache2/sites-available/server1.example.com

Then add:

<VirtualHost *:80>JkMount /* defaultServerName server1.example.comServerAdmin webmaster@server1.example.comDocumentRoot /var/www/server1.example.com/htdocsErrorLog /var/www/server1.example.com/logs/error.logCustomLog /var/www/server1.example.com/logs/access.log combined<Directory /var/www/server1.example.com/htdocs>Options -Indexes</Directory></VirtualHost>

Note: JkMount can be setup in different ways.

JkMount /* will use tomcat for all files
JkMount /*.jsp only for .jsp files
JkMount /folder/* for tomcat files in a specific directory

Enable the new virtual host we created, by running:

a2ensite server1.example.com

6 Setup a new virtual host in Tomcat6

Open up the configuration file for Tomcat6:

vi /etc/tomcat6/server.xml

Find the following lines:

<!--<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />-->

And uncomment the connector port, like this:

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

Then scroll down and find:

  </Host></Engine>

AFTER the ending </Host> tag, and BEFORE the ending </Engine> tag, insert the following:

<!-- server1.example.com -->

<Host

 name="server1.example.com"

 appBase="/var/www/server1.example.com"

 unpackWARs="true"

 autoDeploy="true">

<Context

 path=""

 docBase="htdocs"

 debug="0"

 reloadable="true"/>

<Valve

 className="org.apache.catalina.valves.AccessLogValve"

 directory="/var/www/server1.example.com/logs"

  prefix="tomcat_access_"

 suffix=".log"

 pattern="common"

 resolveHosts="false"/>

</Host>

Make sure you replace server1.example.com with your details in all the places.

Now lets create a Catalina folder for our new domain:

mkdir /etc/tomcat6/Catalina/server1.example.com

And copy the original context files to new domain:

cp /etc/tomcat6/Catalina/localhost/* /etc/tomcat6/Catalina/server1.example.com/

But remove the ROOT.xml file, because we don't need that one on our new domain:

rm -f /etc/tomcat6/Catalina/server1.example.com/ROOT.xml

4.5 Create a test file and test our new setup

Create a new test.jsp file for our new virtual host:

vi /var/www/server1.example.com/htdocs/test.jsp

and add:

<html><head><title>Hello World</title></head><body><h1>Hello World</h1>Today is: <%= new java.util.Date().toString() %></body></html>

Save and exit the file.

Finally restart the services, so that the new configuration will load:

/etc/init.d/apache2 stop
/etc/init.d/tomcat6 restart
/etc/init.d/apache2 start

Then use your browser to visit http://server1.example.com/test.jsp and verify that you get the test page we just created.

You should also be able to visit http://server1.example.com/examples which is now also available on our virtual host (/docs, /manager/html and /host-manager/html should also work):
