Apache Tomcat installation directory in ubuntu / Tomcat configuration in eclipse + ubuntu

advertisements

I installed java7 and ApacheTomcat7 in my Ubuntu12.04, and download eclipse EE. And now I have to configure my eclipse with tomcat. For I want to find the tomcat installation directory. How can I find it. I installed java and tomcat using Ubuntu software centre.


1. Download the package "apache-tomcat-7.0.6.tar.gz" from the below link
http://tomcat.apache.org/download-70.cgi [tar.gz]

2. Now unpack it with the following command:

tar xvzf apache-tomcat-7.0.8.tar.gz

3. Then move to more appropriate directory, in our case in /usr/share/tomcat7, but can be in any directory. We do this with the command:

sudo mv apache-tomcat-7.0.8/ /usr/share/tomcat7

4. Now define the environment variables JAVA_HOME and JRE_HOME. This file is in the "environment" in / etc. Command to edit the file:

sudo gedit /etc/environment

5. Here we record the routes where we have installed Java in my case this is as follows:

JAVA_HOME="/usr/local/jdk1.6.0_23"
JRE_HOME="/usr/local/jdk1.6.0_23/jre"
PATH="...(other path):$JAVA_HOME:$JRE_HOME"

6. IMPORTANT: Verify the routes where they have installed Java.

sometimes tomcat does not recognize, but a surefire way of recognizing that tomcat is to define the file paths inside "catalina.sh" located in tomcat7/bin. To modify this file use the command:

sudo gedit /usr/share/tomcat7/bin/catalina.sh

Now insert the JAVA_HOME and JRE_HOME after the first line, so the file is as follows:

#!/bin/sh
JAVA_HOME="/usr/local/jdk1.6.0_23"
JRE_HOME="/usr/local/jdk1.6.0_23/jre"
# Licensed to the Apache Software Foundation (ASF)...
#...
#...
....

Now configure Tomcat users, this is done in the file "tomcat-users.xml" directory tomcat7/conf. Command to edit the file:

sudo gedit /usr/share/tomcat7/conf/tomcat-users.xml

7. Unlike previous versions, the administrator should own role "manager" now it should be "manager-gui"to operate on the web administration tomcat7. The file would be as follows:

<?xml version='1.0' encoding='utf-8'?>

<tomcat-users>
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager"/>
<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<role rolename="admin"/>

<user username="usuario" password="contrasena" roles="manager-gui,admin-gui,manager,admin,manager-script,admin-script"/>
</tomcat-users>
