Tomcat can be run as a daemon using the jsvc tool from the
commons-daemon project. Source tarballs for jsvc are included with the
Tomcat binaries, and need to be compiled. Building jsvc requires
a C ANSI compiler (such as GCC), GNU Autoconf, and a JDK.
Before running the script, the
variable should be set to the base path of the JDK. Alternately, when
./configure script, the path of the JDK may
be specified using the
--with-java parameter, such as
Using the following commands should result in a compiled jsvc binary,
located in the
$CATALINA_HOME/bin folder. This assumes
that GNU TAR is used, and that
CATALINA_HOME is an
environment variable pointing to the base path of the Tomcat
Please note that you should use the GNU make (gmake) instead of
the native BSD make on FreeBSD systems.
Download a commons-daemon binary from the Jakarta Commons download page,
and place jsvc.tar.gz and commons-daemon.jar in the
tar xvfz jsvc.tar.gz
cp jsvc ..
Tomcat can then be run as a daemon using the following commands.
./bin/jsvc -cp ./bin/bootstrap.jar \
-outfile ./logs/catalina.out -errfile ./logs/catalina.err \
jsvc has other useful parameters, such as
causes it to switch to another user after the daemon initialization is
complete. This allows, for example, running Tomcat as a non privileged
user while still being able to use privileged ports.
jsvc --help will return the full jsvc usage
information. In particular, the
-debug option is useful
to debug issues running jsvc.
$CATALINA_HOME/bin/jsvc/native/tomcat.sh can be
used as a template for starting Tomcat automatically at boot time from
/etc/init.d. The file is currently setup for running
Tomcat 4.1.x, so it is necessary to edit it and change the classname
Note that the Commons-Daemon JAR file must be on your runtime classpath
to run Tomcat in this manner. The Commons-Daemon JAR file is in the Class-Path
entry of the bootstrap.jar manifest, but if you get a ClassNotFoundException
or a NoClassDefFoundError for a Commons-Daemon class, add the Commons-Daemon
JAR to the -cp argument when launching jsvc.
