how to create startup script?

samengr · 04-03-2008, 08:07 AM

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/sh
#
# 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.

i think you saved the file in msdos format, if you open the file in vi you'll probably see ^M's at the end of each line, which (afair) is the linefeed character which is used in dos format but not unix format.

you can clean up those carriage returns in vim with:

Code:

:1,$s/\r//

On a Debian, I have my startup scripts as :
/etc/rc2.d/S99startupscripts
chmod +rx /etc/rc2.d/S99startupscripts

and they starts with #/bin/bash
bla bla

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?

You can always use dos2unix to convert a file from msdos to unix format. For details:

Code:

man dos2unix

I used the same command dos2unix /etc/rc.d/tomcat,
but still 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."

please help me to solve this issue.

I cannot figure out what happens with your script. I've tested in my system and ti works. Can you try the following much simpler script to see if it works (change JAVA_HOME if needed)?

Code:

#!/bin/sh
# Tomcat Startup Script

export CATALINA_HOME=/opt/tomcat
export JAVA_HOME=/usr/java
export TOMCAT_OWNER=tomcat

start() {
        echo -n "Starting Tomcat:  "
        su $TOMCAT_OWNER -c $CATALINA_HOME/bin/startup.sh
}
stop() {
        echo -n "Stopping Tomcat: "
        su $TOMCAT_OWNER -c $CATALINA_HOME/bin/shutdown.sh
}

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