Dieser Artikel ist eine überarbeitete Version meines Tomcat 5.5 Artikels. Ich habe diesmal die Installation des Open Bluedragon in einen eigenen Artikel getrennt beschrieben. Es soll Tomcat 6 unter Debian Lenny installiert werden und mit mehreren virtuellen Hosts betrieben werden. Tomcat 6 ist unter Debian leider nicht über die Quellen zu beziehen, deshalb muss er manuell installiert werden. (Ubuntu bietet Tomcat 6 per apt-Installation an)
1. Installation von Java 6 runtime:
Eine der folgenden Java JDK Installationen wählen:
1.1 OpenJDK
aptitude install java6-runtime
1.2 Sun JDK (non-free)
vim /etc/apt/sources
deb http://ftp.de.debian.org/debian/ lenny main non-free deb-src http://ftp.de.debian.org/debian/ lenny main non-free
aptitude update aptitude install sun-java6-jdk
Bemerkung: Nicht vergessen, dass eine andere Konfiguration beim Apache Connector erforderlich sein wird, sollte Sun JDK verwendet werden.
2. Download Tomcat
Download Tomcat 6 von der Tomcat 6 Download Seite.
Zum Beispiel:
wget http://apache.imsam.info/tomcat/tomcat-6/v6.0.18/bin/apache-tomcat-6.0.18.tar.gz
3. Installation von Tomcat
tar -xzvf apache-tomcat-6.0.18.tar.gz mv apache-tomcat-6.0.18 /opt/tomcat
4. Init-Skript erstellen
vim /etc/init.d/tomcat
#!/bin/sh
# Tomcat Init-Script
case $1 in
start)
sh /opt/tomcat/bin/startup.sh
;;
stop)
sh /opt/tomcat/bin/shutdown.sh
;;
restart)
sh /opt/tomcat/bin/shutdown.sh
sh /opt/tomcat/bin/startup.sh
;;
esac
exit 0
update-rc.d tomcat defaults
5. Aktivieren des Tomcat Managers
vim /opt/tomcat/conf/tomcat-users.xml
<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
<role rolename="manager"/>
<role rolename="admin"/>
<user username="YOUR_USERNAME" password="YOUR_PASSWORD" roles="admin,manager"/>
</tomcat-users>
6. Start Tomcat
/etc/init.d/tomcat start
Nun kann man den Tomcat Manager mit http://SERVER:8080/manager/html aufrufen.
5. Installation des Apache2 Connectors
Tomcat besitzt zwar einen eingebauten Webserver, jedoch ist der Apache2 Webserver wesentlich leistungsfähiger außerdem sind so die Apache Module verwendbar. (mod_rewrite zum Beipiel)
aptitude install apache2 libapache2-mod-jk
vim /etc/apache2/workers.properties
workers.tomcat_home=/opt/tomcat workers.java_home=/usr/lib/jvm/java-6-openjdk ps=/ worker.list=default worker.default.port=8009 worker.default.host=localhost worker.default.type=ajp13 worker.default.lbfactor=1
Bemerkung: Falls die non-free Java Runtime von Sun verwendet wird, muss “/usr/lib/jvm/java-6-openjdk” durch “/usr/lib/jvm/java-6-sun” ersetzt werden.
JK Konfigurationsdatei
vim /etc/apache2/conf.d/jk.conf
<ifmodule mod_jk.c>
JkWorkersFile /etc/apache2/workers.properties
JkLogFile /var/log/apache2/mod_jk.log
JkLogLevel error
</ifmodule>
/etc/init.d/apache2 stop /etc/init.d/tomcat restart /etc/init.d/apache2 start
6. Neuen Virtuellen Host anlegen
Nun soll ein neuer VirtualHost angelegt werden. Dieser muss im Apache und im Tomcat angelegt werden.
6.1 Verzeichnisse anlegen
mkdir /var/www/vhost1 mkdir /var/www/vhost1/htdocs mkdir /var/www/vhost1/logs
vim /etc/apache2/sites-available/vhost1
6.2 Apache
<virtualhost www.testsrv.local>
JkMount /*.jsp default
ServerName www.testsrv.local
ServerAdmin servermaster@testsrv.local
DocumentRoot /var/www/vhost1/htdocs
ErrorLog /var/www/vhost1/logs/error.log
CustomLog /var/www/vhost1/logs/access.log common
<directory /var/www/vhost1/htdocs>
Options -Indexes
</directory>
</virtualhost>
Bemerkung: Man könnte auch alle Dateien an den Tomcat weiterleiten “JkMount /*” oder alle Dateien innerhalb eines Verzeichnisses “JkMount /folder/*“.
a2ensite vhost1 /etc/init.d/apache2 reload
6.3 Tomcat
vim /opt/tomcat/conf/server.xml
<!-- www.testsrv.local -->
<host name="www.testsrv.local" appBase="/var/www/vhost1" unpackWARs="true" autoDeploy="true">
<context path="" docBase="htdocs" debug="0" reloadable="true"/>
<valve className="org.apache.catalina.valves.AccessLogValve" directory="/var/www/vhost1/logs" prefix="tomcat_access_" suffix=".log" pattern="common" resolveHosts="false"/>
</host>
/etc/init.d/tomcat restart
Bemerkung: Man kann weitere Domains mit:
<alias>additionaldomain.com</alias>
hinzufügen.
7. Testseite anlegen
vim /var/www/vhost1/htdocs/test.jsp
<html>
<head>
<title>Hello World</title>
</head>
<body>
<h1>Hello World</h1>
Today is: <%= new java.util.Date().toString() %>
</body>
</html>
Nun kann man durch den Aufruf von http://www.testsrv.local/test.jsp die Konfiguration/Installation testen.

Danke für das kleine howto. Hat mir weitergeholfen
Ein kleiner Fehler hat sich in der tomcat-users.xml eingeschlichen: Die Tags müssen und heissen.
Cheers
Hallo,
danke für den Hinweis. Ich denke ich habe alles entsprechend korrigiert, auch wenn die Tags aus deinem Kommentar entfernt wurden …
Danke
This page of instructions has been extremely helpful. Many thanks for putting together this comprehensive and well laid out page.
hi is a great how to but i have a lot of doubts 1. how i make that test page shows in my others computer a lan of four computer witn s.o. windows 2 do you know how connect this configuration with postgresql
bye
Hi rolando,
i don’t understand your problem with the lan computers, i need more informations.
For PostgresSQL you need the JDBC driver from http://jdbc.postgresql.org/download and save this in the “lib” folder of your “WEB-INF” folder.
And insert between the context tag the jdbc resource:

bye
pd
recommend a book for doing this
hi i have tomcat 6 working without any configuration then follow the steps to make a virtual host because i want learn how configured that everything okay but when put /etc/init.d/tomcat restart appears various lines of errors “expected a token in line 54 …” after that i try to open the server.xml to erase the modifications but only appears the erros so i try stop tomcat and the same open another terminal the same so i close all after that let me open server.xml and put the backup restart all no errors…. apparently because now start tomcat but in the browser only says waiting for localhost
How uninstall tomcat apache2 but deleting all the files for make a clean installation and star over
take care
(i made a copy server.xml at the moment apache2 not installed later install)
Three cheers for the creator of this howto!!! I havnt tested it yet but this actually looks like tomcat made operational in a virtual host environment!
Thank you…Thank you … Thank you.
Hello,
Thanks for the tutorial. I had 2 questions:
1°) I followed the instructions above (with OpenJDK). Everything went fine until step 7. When I try the test.jsp, the code was just dumped in the browser instead of being interpreted. Why?
2°) Where should I place my WAR files for the deployment? In the /opt/tomcat/webapp directory or in the /var/www/vhost1 directory?
Thanks a lot for your help.
Hi,
1) Check if the apache connector is installed and working and if you created the JkMount entry in the virtual host configuration.
2) We moved the tomcat webapp path to appBase=”/var/www/vhost1″ in the host configuration so you have to place the war files there. Make sure you have the setting unpackWARs=”true” and autoDeploy=”true”.
cheers
Sebastian
Hi Sebastian,
Thanks for your fast answer!
I made some modifications (the JkMount entry was not defined indeed) and now, the HTML code is displayed properly but my browser still does not interpred the Java piece of code…
Any idea?
Thanks?
Hi,
make sure you have installed libapache2-mod-jk and check the settings in /etc/apache2/workers.properties
Watch the syslog on apache startup and take a look at the apache error and access logs.

Hallo,
ich habe eben mal die Anleitung auf meinem Lenny System getestet, zuerst musste ich im Apache vhost1 File in ändern, da sonst bei Aufruf des VHosts im falschen Verzeichnis gesucht wurde. Nun habe ich aber das Problem, das meine test.jsp gefunden wird, allerdings weder der Quelltext dieser, noch die Testseite erscheint. D.h. wenn ich mir den Quelltext anzeigen lasse, ist dieser leer. Irgendwelche Ideen wo der Fehler liegt?
Hi,
leider wurde deine Änderung im Kommentar nicht mit gespeichert. Kann dir so leider nicht helfen. Pack deine vhost1 config doch mal in http://pastebin.com und schick mir dann den entsprechenden Link dazu.

Hi, good post. I have been wondering about this issue,so thanks for posting.
Wow … that is one of the best tutorials I have ever read!
)
It works also with little changes in Etch.
Many thanks …
Thanks for the tutorial!
One thing is missing which is vital for production use: in your configuration tomcat runs with superusercredentials.
First this is unnessesary hence tomcat runs by default on a unprevileged port 8080.
Secondly every application on the tomcat instance will have full rights on your machine. This means every security issue on a single application can cause the full compromise of your machine!
Please consider using something like
su tomcat /opt/tomcat/bin/startup.sh
where tomcat is a nonprivileged user.

How soon will you update your blog? I’m interested in reading some more information on this issue.
As soon as possible …
I currently working on a new startup script.
Hi Everyone,
Have a look at the blog given below for multiple instances of apache tomcat6 on debian lenny just in few very easy steps;
http://www.itoperationz.com/2009/07/multiple-instances-of-apache-tomcat-6-on-debain5-lenny/
Please post your valueable comments.

this works great on ubuntu too
thanks Man
Hi there !
There’s an extra space in the code for your test page : “< %=" should be "<%="
I spent two hours looking for the reason why i couldn't get this "simple" page working !
Thanks for this great tutorial by the way !
Thank you !
I removed the extra space from the example.
It is not working with me!!!!!! I even don’t know where is the mistake!!!
