how to create startup script?

[shamuk80]

Hi All

I have installed tomcat on RHEL4/5. It doesnt create start/stop scripts in /etc/rc.d/init.d/ --> /etc/init.d/.

Now i am stoping and starting tomcat by
#/opt/tomcat/bin/startup.sh
#/opt/tomcat/bin/shutdown.sh

but i want to configure this in a script in init.d/ directory.

I tired my self by writing a script after seeing the others in /etc/rc.d/init.d/

#!/bin/bash
#
# description: Jakarta Tomcat Java Servlets and JSP server
# processname: tomcat

start_tomcat=/opt/tomcat/bin/startup.sh
stop_tomcat=/opt/tomcat/bin/shutdown.sh

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

# Source networking configuration.
. /etc/sysconfig/network

# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0

start() {
echo -n "Starting tomcat: "
su -c ${start_tomcat} - tomcat
echo "done."
}
stop() {
echo -n "Shutting down tomcat: "
# Add stop flag file
touch $CATALINA_HOME/temp/.manualStop
su -c ${stop_tomcat} - tomcat
echo "done."
}

# See how we were called
case "$1" in
start)
start
;;
stop)
stop
;;
restart)
stop
sleep 10
start
;;
*)
echo "Usage: $0 {start|stop|restart}"
esac

exit 0



but i am getting error if i run this script.

[root@localhost /]/etc/init.d/tomcat stop
-bash: /etc/init.d/tomcat: /bin/sh^M: bad interpreter: No such file or directory.

/etc/init.d/tomcat start/stop/restart.


Can any body help me to see whats wrong here?
Thanks.

bash: /etc/init.d/tomcat: /bin/sh^M: bad interpreter: No such file or directory.
You created this file in a Windows editor!

I know because if the ^M character. Windows editors like notepad end each line with a "\r\n" sequence instead of the Unix-world's "\n". And "\r" is the same character as ^M.

Logic would say that Linux should consider the ^M to be whitespace and ignore it, but it doesn't. So it sees /bin/sh^M (which doesn't exist) instead of /bin/sh .

So just edit it in a Linux editor and delete those ^M's.

Hi ya,

I have typed it now in vi editor by removing the previous one but getting the same error. "-bash: /etc/init.d/tomcat: /bin/sh^M: bad interpreter: No such file or directory." Even i replaced /bin/bash to /bin/sh but it didnt work and the same error "bash: /etc/init.d/tomcat: /bin/bash^M: bad interpreter: No such file or directory."

Any body can see this problem?

Try this command:

dos2unix /etc/init.d/tomcat

If the dos2unix command isn't already installed, install the dos2unix package.

Be careful that you aren't editing one file and executing another. I've done that before.

For example, in your comment you said you ran the command on /etc/rc.d/tomcat. But that's not the script that is used to start the service, and it's not the one mentioned in the error message, /etc/init.d/tomcat.

Even if that was just a typo in the message or there is some symbolic link trickery, this problem sounds like the kind of problem I've had before where I kept editing and changing and trying new things but always always got the exact same result. In those situations I usually discovered I wasn't editing the right file.

One last thing you might look for is the file /etc/init.d/tomcat5. That's what my Mandriva system uses.
