Apache-Tomcat

By AdNovea – June 2009 – version 1.0 

 

Apache Tomcat is an implementation of the Java Servlet and JavaServer Pages technologies. The Java Servlet and JavaServer Pages specifications are developed under the Java Community Process. Apache Tomcat powers numerous large-scale, mission-critical web applications across a diverse range of industries and organizations.

Installation

IMPORTANT: Apache-Tomcat requires the JRE QPKG [1] to be up and running.

• Download, Install and Enable the JRE QPKG first
• Download, Install and Enable the Apache-Tomcat QPKG.

[1] JRE QPKG is available only for the x86 QNAP Platform. Please refer to the SUN Java website about the release conditions for other processors.

Apache-Tomcat Administration

In your browser enter the following address [2]:

http://<your_nas_ip>:7080/

[2] Forward the port to access the Apache-Tomcat server from external network

• To change the Apache-Tomcat port, edit the section below in the conf/server.xml file:

    <Connector port="7080" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443" />

Set up the Administrator account

If the page here above is displayed, it means that Apache-Tomcat is running.
Nevertheless don't be surprised if you cannot access the Status or the Tomcat Manager. You must first setup the Admin account.
Open the usr/local/tomcat/conf/tomcat-users.xml file using an SFTP client like Transmit(OS X) or WinSCP(Windows), and using a text editor insert the content below between the tags (change with secret):

  <role rolename="manager"/>
  <user username="manager" password="password" roles="manager"/>

• The conf/tomcat-users.xml manages all users permissions as shown in the example below:

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
  <role rolename="manager"/>
  <role rolename="tomcat"/>
  <role rolename="admin"/>
  <role rolename="role1"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="admin" password="admin" roles="admin,manager"/>
  <user username="role1" password="tomcat" roles="role1"/>
</tomcat-users>
