Installing and Configuring Tomcat In Linux -Step by Step Configuration instructionsInstalling to Linux - The installation is much simpler on a Linux than a Windows machine. The first thing you need to do is install the JDK. For our purposes, we will assume that the JDK will be installed to /root/java.
After you have the JDK installed, you need to set the JAVA_HOME environment variable. To do this under Linux, find your shell in Table 2 and type the matching command. You will need to replace /root/java with the root location of your JDK installation.
Java Environment Settings bash shell
# JAVA_HOME=/root/java
# export JAVA_HOME
You should add the location of the Java interpreter to your PATH environment variable.
You now need to extract the Tomcat server to a directory of your choosing. This directory will become the TOMCAT_HOME directory. For this installation, we will assume that Tomcat will be installed to /root/Tomcat6.0
The last step is to set the TOMCAT_HOME environment variable. To do this under Linux, find your shell in Table 3 and type the matching command. You will need to replace /bob with the name of the directory located directly above your Tomcat installation.
Tomcat Environment Settings Base Shell
# TOMCAT_HOME = /root/Tomcat6.0
# export TOMCAT_HOME
Testing Your Tomcat Installation
To test the Tomcat installation, first start the Tomcat server. Table 4 contains the startup and shutdown commands for each OS.
Tomcat Startup/Shutdown Commands
Windows NT/2000/XP
TOMCAT_HOME\bin\startup.bat
TOMCAT_HOME\bin\shutdown.bat
ex:
cd c:\tomcat6.0\bin
c:\>tomcat6.0\bin\startup.bat
c:\>tomcat6.0\bin\shutdown.bat
Linux
TOMCAT_HOME/bin/startup.sh
TOMCAT_HOME/bin/shutdown.sh
ex:
# cd /root/tomcat6.0/bin
[/root/tomcat6.0/bin]# ./startup.sh
[/root/tomcat6.0/bin ]# ./shutdown.sh
Once Tomcat has started, point your browser at
http://localhost:8080/
You should see a page similar to Figure 5.
Screen shot.
Figure 5. The Tomcat Default Page
If you would like to have all requests serviced on the default HTTP port of 80, instead of port 8080, you will need to make the following change to the TOMCAT_HOME/conf/server.xml file and restart Tomcat.
Change
<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
<Connector className="org.apache.catalina.connector.http.HttpConnector"
port="8080" minProcessors="5" maxProcessors="75"
acceptCount="10" debug="0"/>
to
<!-- Define a non-SSL HTTP/1.1 Connector on port 80 -->
<Connector className="org.apache.catalina.connector.http.HttpConnector"
port="80" minProcessors="5" maxProcessors="75"
acceptCount="10" debug="0"/>
Now point your browser at
http://localhost/
and you'll see results similar to those in Figure 5.
