Hello,
I have my application in production for a month now. I've some problem
of memory leak that force me to restart TC each few days. I'm trying
to automate this operation with a cron that runs a *.sh file. But I
don't know how what to write in it. Actually, I've this:
do you have shebang header in your script ? - something like this #!/bin/sh
and do you have tomcat running under root ? -this is very not secure ...
/usr/local/tomcat/bin/shutdown.sh
killall -9 java
/usr/local/tomcat/bin/startup.sh
But when I run it using SSH, it makes a weird error:
[EMAIL PROTECTED] bin]# /usr/local/tomcat/bin/restart.sh
: No such file or directoryrt.sh: line 1:*
/usr/local/tomcat/bin/shutdown.sh*
are this script executable ? if not use chmod to set for example 755
permissions
another thing about CRON , absolute paths to scripts must be used ...
: no process killed
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr/java/jre1.5.0_06
... but shutdown.sh exists!
Does anybody have an example of a script that restart Tomcat?
I have one , I use it for my init script for tomcat ...
if you are interesting in bash scripting , here is great manual
http://www.tldp.org/LDP/abs/ or just google "Advanced Bash-Scripting
Guide"
restart.sh
#!/bin/sh
TOMCAT_USER="tomcat"
CATALINA_HOME="/opt/tomcat"
PATH=/bin:/sbin:/usr/bin:/usr/sbin
startdaemon="$CATALINA_HOME/bin/startup.sh"
stopdaemon="$CATALINA_HOME/bin/shutdown.sh"
export CATALINA_HOME
case "$1" in
start)
sudo -u $TOMCAT_USER $startdaemon >>
"$CATALINA_HOME/logs/catalina.out" 2>&1
;;
stop)
sudo -u $TOMCAT_USER $stopdaemon >>
"$CATALINA_HOME/logs/catalina.out" 2>&1
while [[ "$i" -lt "10" ]]
do
status=`pidof java 2>&1>/dev/null ; echo $?`
if [[ $status == '0' ]]
then
echo -n "."
sleep 2
fi
let "i += 1"
done
status=`pidof java 2>&1>/dev/null ; echo $?`
if [[ $status == '0' ]]
then
echo "Killing ALL JAVA Processes"
/usr/bin/killall -9 java
fi
;;
restart)
echo "Stopping Tomcat"
$0 stop
sleep 2
echo "Starting Tomcat"
$0 start
;;
*)
echo "Usage: $0 {start|stop|restart}"
exit 1
;;
esac
exit 0
Thanks a lot!
