11.2. Starting Tomcat
Problem
You want to get Tomcat running.
Solution
Set the JAVA_HOME
and
CATALINA_HOME
environment variables, change
directories to Tomcat’s bin
directory, and type startup
in Windows or run
startup.sh
in Unix.
Discussion
Before starting Tomcat from the command line, you must set these two environment variables:
-
JAVA_HOME
You set this environment variable to the installation directory of Java, the parent directory of the Java
bin
directory; e.g.,C:\jdk1.4
in Windows or/usr/java
in Unix.-
CATALINA_HOME
You set this environment variable to the installation directory of Tomcat, the parent directory of the Tomcat
bin
directory; e.g.,C:\tomcat\jakarta-tomcat-5.0.19
in Windows.
You can set these environment variables from the command prompt (in Windows that’s the DOS prompt; in Unix it’s the shell) as in this example:
set JAVA_HOME=C:\jdk1.4
How you do this varies by operating system; for example, in the Unix
tcsh
shell, use setenv
instead.
After setting these environment variables, run Tomcat by changing
directories to Tomcat’s bin
directory and typing startup
in Windows, or
running startup.sh
in Unix. Note that in Windows,
a new DOS window appears that displays initialization messages. To
shut down Tomcat, type shutdown
in Windows, or run
shutdown.sh
in Unix at the command line.
Now that you’ve gotten Tomcat running, open a browser, and navigate to http://localhost:8080, which should open Tomcat’s Welcome page, as shown in Figure 11-1. The localhost part of this URL is ...
