Creating a Unix Service for ActiveMQ
Below are steps to make ActiveMQ a Linux Daemon on Red Hat 4 ES.
It's based on this article.
Alternatively, you could also use the Java Service Wrapper implementation, refer to the Java Service Wrapper Page for more details.
Settings
![]() Codeblock |
JAVA_HOME = /opt/java/jdk1.5.0_06
ActiveMQ = /opt/activemq/incubator-activemq-4.0
|
Installation
Sun Java JDK
1. Install Sun Java JDK on /opt/java/ directory.
2. Create a shortcut to JDK directory:
![]() Codeblock |
sudo ln -s /opt/java/jdk1.5.0_06 /opt/java/java
|
ActiveMQ
1. Install ActiveMQ on /opt/activemq/ directory.
2. Make ActiveMQ startup and shutdown scripts executable:
![]() Codeblock |
sudo chmod +x /opt/activemq/incubator-activemq-4.0/bin/activemq
sudo chmod +x /opt/activemq/incubator-activemq-4.0/bin/shutdown
|
ActiveMQ as Linux Daemon
1. Create activemq user:
![]() Codeblock |
sudo /usr/sbin/useradd activemq
|
2. Create ActiveMQ startup script /home/activemq/activemqstart.sh with the
following content:
![]() Codeblock |
#!/bin/bash
export JDK_HOME=/opt/java/java
export JAVA_HOME=/opt/java/java
/opt/activemq/incubator-activemq-4.0/bin/activemq &
|
3. Make /home/activemq/activemqstart.sh executable:
![]() Codeblock |
sudo chmod +x /home/activemq/activemqstart.sh
|
4. Create ActiveMQ shutdown script /home/activemq/activemqstop.sh with the
following content:
![]() Codeblock |
#!/bin/bash
export JDK_HOME=/opt/java/java
export JAVA_HOME=/opt/java/java
/opt/activemq/incubator-activemq-4.0/bin/shutdown
|
5. Make /home/activemq/activemqstop.sh executable:
![]() Codeblock |
sudo chmod +x /home/activemq/activemqstop.sh
|
6. Create ActiveMQ Linux service configuration script /etc/init.d/activemq
with the following content:
![]() Codeblock |
#!/bin/bash
#
# activemq Starts ActiveMQ.
#
#
# chkconfig: 345 88 12
# description: ActiveMQ is a JMS Messaging Queue Server.
### BEGIN INIT INFO
# Provides: $activemq
### END INIT INFO
# Source function library.
. /etc/init.d/functions
[ -f /home/activemq/activemqstart.sh ] || exit 0
[ -f /home/activemq/activemqstop.sh ] || exit 0
RETVAL=0
umask 077
start() {
echo -n $"Starting ActiveMQ: "
daemon /home/activemq/activemqstart.sh
echo
return $RETVAL
}
stop() {
echo -n $"Shutting down ActiveMQ: "
daemon su -c /home/activemq/activemqstop.sh activemq
echo
return $RETVAL
}
restart() {
stop
start
}
case "$1" in
start)
start
;;
stop)
stop
;;
restart|reload)
restart
;;
*)
echo $"Usage: $0 {start|stop|restart}"
exit 1
esac
exit $?
|
7. Enable ActiveMQ service configuration as Linux Daemon:
![]() Codeblock |
sudo chmod +x /etc/init.d/activemq
sudo /sbin/chkconfig --add activemq
sudo /sbin/chkconfig activemq on
|
8. Restart the server.
Note: activemq-data is being created in "/" root directory. I have to
explicitly set the activemq-data location in activemq.conf
This page contained a very basic procedure to create a unix service for activemq.
Due to the fact that ActiveMQ contains a very functional init script - this is not needed anymore.
Review the documentation of the init script: Unix Shell Script
