Install Apache Tomcat 5.5 on Ubuntu 8.04 Hardy
To install and run Tomcat on Ubuntu (8.04 over here) the following packages should be installed from synaptic :
They can be installed from command line using the command sudo apt-get
After synaptic finishes installing them open /etc/default/tomcat5.5 and edit it as follows :
Change : Remove the # so that it is uncommented.
It points to the java home which can be java-6-sun or any other java .
Then restart tomcat5.5 from command line like this :
[email protected]:~$ sudo /etc/init.d/tomcat5.5 restart * Stopping Tomcat servlet engine tomcat5.5 [ OK ] * Starting Tomcat servlet engine tomcat5.5 [ OK ]
Now open in your browser the url :http://localhost:8180/
And the welcome page of Apache Tomcat should appear.
has the default username and password listed which is username : tomcat and password : tomcat.
On the tomcat welcome page Tomcat Administration link is on the left :http://localhost:8180/admin
Opening this page might show the error message :
HTTP Status 403 - Access to the requested resource has been denied
To fix the above issue open the file
sudo gedit /usr/share/tomcat5.5/conf/tomcat-users.xml
and add a role called admin and user called admin with that role :
<user username="admin" password="tomcat" roles="tomcat,admin"/>
Restart tomcat from command line as shown above.
Now log in to the administration panel :
with username : admin and password : tomcat.
The login should take you to the admin panel without any error.
To the left is another link of Tomcat Manager :
which might still show the error of Access denied.
To fix this issue simply login to the admin panel and create a role called manager (if it doesnt exist) and assign this role to a non-admin user like tomcat or create a new user.
Then log in to the Tomcat Manager page and it should open fine without any errors.
Now /usr/share/tomcat-webapps is the folder that contains the jsp files/webapps which are accessible from localhost:8180 url.
To change the directory of webapps to say one in /home/username/tomcat
Open : /usr/share/tomcat5.5-webapps/ROOT.xml
Look for :
Context path="/" docBase="/usr/share/tomcat5.5-webapps/ROOT"
and change the docBase value to the folder where the tomcat webapps would be.
Context path="/" docBase="/home/enlightened/tomcat"
Context path="/" docBase="/var/www/tomcat"
Save the file and restart tomcat.
One more thing you can do is copy the contents of the /usr/share/tomcat5.5-webapps/ROOT directory to this new directory and then open the url localhost:8180 to check that everything is working fine. The admin and manager pages on the left and the jsp examples also should all open fine as previously.
