[SOLVED] tomcat startup script

tkmsr · 02-17-2011, 02:46 AM

I am looking for a tomcat start up script on a Ubuntu machine.
My Ubuntu is 10.04 server.
The tomcat is 5.5.30.

It is in /opt/apache-tomcat-5.5.31

I tried a script here

Code:

#!/bin/bash
#
# tomcat        
#
# chkconfig: 
# description: 	Start up the Tomcat servlet engine.

# Source function library.
. /etc/init.d/functions


RETVAL=$?
CATALINA_HOME="/opt/apache-tomcat-5.5.31"

case "$1" in
 start)
        if [ -f $CATALINA_HOME/bin/startup.sh ];
          then
	    echo $"Starting Tomcat"

        fi
	;;
 stop)
        if [ -f $CATALINA_HOME/bin/shutdown.sh ];
          then
	    echo $"Stopping Tomcat"

        fi
 	;;
 *)
 	echo $"Usage: $0 {start|stop}"
	exit 1
	;;
esac

exit $RETVAL

but it did not worked after a reboot.

Hi,

Does it work when you run it directly, like /etc/init.d/tomcat?
If it does, you can run:

Code:

sudo update-rc.d tomcat defaults

to create the needed symlinks in the various runlevels

Regards

Ok When I run it directly as you mentioned
/etc/init.d/tomcat
then I get error

Quote:

./tomcat: line 9: /etc/init.d/functions: No such file or directory
Usage: ./tomcat {start|stop}

Ok I realized the mistake in the line above in rest of the init scripts on my server the line for init-functions is

Quote:

. /lib/lsb/init-functions

So now I changed the script to

Code:

. /lib/lsb/init-functions
RETVAL=$?
CATALINA_HOME="/opt/apache-tomcat-5.5.31"
case "$1" in
 start)
        if [ -f $CATALINA_HOME/bin/startup.sh ];
          then
            echo $"Starting Tomcat"
        fi
        ;;
 stop)
        if [ -f $CATALINA_HOME/bin/shutdown.sh ];
          then
            echo $"Stopping Tomcat"
        fi
        ;;
 *)
        echo $"Usage: $0 {start|stop}"
        exit 1
        ;;
esac
exit $RETVAL

and now I executed /etc/init.d/tomcat
the problem I saw basically now is that my application which is currently here
/opt/apache-tomcat-5.5.31
is now in accessible.
I am using tomcat 5.5
and to start each time that
I do an ssh and then cd /opt/apache-tomcat-5.5.31/bin
and then type startup.sh then it does start.
But not when this script is in a format as above.

The default runlevels to start services are 2 3 4 5, so I guess that's why it isn't starting on rcS.

Quote:

Only things that need to be run once to get the system into a consistent state are to be run. The rcS.d directory is NOT meant to replace rc.local. One should not start daemons in this runlevel unless absolutely necessary. Eg, NFS might need the portmapper, so it is OK to start it early in the bootprocess. But this is not the time to start the squid proxy server.

tkmsr · 02-17-2011, 05:16 AM

Ok by the time I saw your message I understood the problem and had edited my Tomcat script is basically wrong.
If you notice

Quote:

if [ -f $CATALINA_HOME/bin/startup.sh ];
then
echo $"Starting Tomcat"
fi

that means if file $CATALINA_HOME/bin/startup.sh exists then
echo $"Starting Tomcat"
thats it.So it was not starting.Any how I modified it more and now it works correctly.

Quote:

#!/bin/bash
#
# tomcat
#
# chkconfig:
# description: Start up the Tomcat servlet engine.

# Source function library.
. /lib/lsb/init-functions

RETVAL=$?
CATALINA_HOME="/opt/apache-tomcat-5.5.31"

case "$1" in
start)
if [ -f $CATALINA_HOME/bin/startup.sh ];
then
echo $"Starting Tomcat"
/opt/apache-tomcat-5.5.31/bin/startup.sh

fi
;;
stop)
if [ -f $CATALINA_HOME/bin/shutdown.sh ];
then
echo $"Stopping Tomcat"
/opt/apache-tomcat-5.5.31/bin/shutdown.sh
fi
;;
*)
echo $"Usage: $0 {start|stop}"
exit 1
;;
esac
exit $RETVAL

So now the scripts does work fine.
I checked

Quote:

/etc/init.d/tomcat start

and

Quote:

/etc/init.d/tomcat stop

update-rc.d tomcat defaults

Now I reboot the machine but after a reboot I did not got the application which was hosted on Tomcat instance.
What I observe is for my application to work when the system boots up I again login via ssh and

Code:

cd /opt/apache-tomcat-5.5.31/bin# 
./startup.sh

and then it works.
So this time the script is also fine so why is this not working?

bathory · 02-17-2011, 05:55 AM

You mean it works when you run:

Code:

/etc/init.d/tomcat start

but not at system startup?
I guess you need to define also JAVA_HOME in your script, because I don't think it's defined at boot time.

tkmsr · 02-17-2011, 06:21 AM

I defined JAVA_HOME as you mention JAVA_HOME but still on boot it failed to start I had to manually go and start by $CATALINA_HOME/bin/startup.sh

bathory · 02-17-2011, 07:12 AM

Does it starts when you run:

Code:

/etc/init.d/tomcat start

If it does, then it should also start from /etc/rc2.d/S20tomcat.
And why do you need to cd into $CATALINA_HOME? What happens if you run

Code:

/opt/apache-tomcat-5.5.31/bin/startup.sh

You should also check the startup logs to see if you find the reason tomcat is not starting.

BTW you can put the above command in /etc/rc.local as it's the last script executed on boot (and of course remove tomcat from rc.d)

Code:

sudo update-rc.d tomcat remove

Yes it runs.

This does not happen.

This also works.

I have following log files in /var/log

Other than this
I have in

but the logs here are all blank.
Which one you are pointing to.

bathory · 02-17-2011, 07:54 AM

I guess the startup logs are written in /var/log/boot /var/log/syslog /var/log/messages and /var/log/daemon. tomcat logs are useless here, eventhough at least catalina.out shouldn't be blank.

Do it as a last resort. It's not bad to use /etc/rc.local (in fact I use it to start almost everything in Slackware), but out of curiosity I would like to see why the other way does not work.

tkmsr · 02-17-2011, 09:02 AM

Ok file /var/log/boot.log has following

Quote:

Starting Tomcat
Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
At least one of these environment variable is needed to run this program
* Starting web server apache2 ^[[80G ^M^[[74G[ OK ]

but this is not correct as JAVA_HOME was defined in script.
daemon.log does not have any thing useful if you want to see here it is http://pastebin.com/mf8SYLnt
even I want to understand why it does not work.

bathory · 02-17-2011, 09:32 AM

It doesn't work because somehow JAVA_HOME is unset.
You can set the JAVA_HOME in /opt/apache-tomcat-5.5.31/bin/catalina.sh, so it's always set.

tkmsr · 02-18-2011, 10:37 AM

Well sorry for the delayed reply I have very strong fever here.I did try JAVA_HOME in catalina.sh but after a reboot it did not worked.

bathory · 02-18-2011, 01:06 PM

Hope you being well.
Are you sure it didn't work. Maybe you see that JAVA_HOME is not set, because it's define inside the catalina.sh script, but tomcat is running. In ubuntu it's something like: JAVA_HOME=/usr/lib/jvm/java-6-sun

tkmsr · 02-21-2011, 06:31 PM

I am sure it did not worked because I had to ssh into the machine and manually do

Quote:

/opt/apache-tomcat-5.5.31/bin/startup.sh

then only things started working.
Ok I just checked things are working at reboot.
Here is the new script

Quote:

#!/bin/bash
#
# tomcat
#
# chkconfig:
# description: Start up the Tomcat servlet engine.

# Source function library.
. /lib/lsb/init-functions

RETVAL=$?
export CATALINA_HOME="/opt/apache-tomcat-5.5.31"
export JAVA_HOME="/usr/lib/jvm/java-6-sun"
#export JAVA_OPTS='-server -Xms512m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=512m -XX:NewSize=192m -XX:MaxNewSize=384m -Djava.awt.headless=true -Dhttp.agent=Sakai -Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false -Dsun.lang.ClassLoader.allowArraySyntax=true'
#export PATH=PATH:$JAVA_HOME/bin
case "$1" in
start)
if [ -f $CATALINA_HOME/bin/startup.sh ];
then
echo $"Starting Tomcat"
/opt/apache-tomcat-5.5.31/bin/startup.sh
fi
;;
stop)
if [ -f $CATALINA_HOME/bin/shutdown.sh ];
then
echo $"Stopping Tomcat"
/opt/apache-tomcat-5.5.31/bin/shutdown.sh
fi
;;
*)
echo $"Usage: $0 {start|stop}"
exit 1
;;
esac

exit $RETVAL

While testing I had removed the links

Quote:

update-rc.d tomcat remove

and had forgotten to link.
So after each reboot it obviously was not working.But I also found one problem in previous scripts
I had used at some places this as follows

Quote:

export CATALINA_HOME="/opt/apache-tomcat-5.5.31/"

but it should be as note the missing slash at end.

Quote:

export CATALINA_HOME="/opt/apache-tomcat-5.5.31"

Now after each reboot it is working fine.

Thanks for your help again.
