Hi, I am a nbee to Unix, I have used following script to check my tomcat is running or not and restart if it down. but actually it restart my tomcat each time running even my tomcat still running fine:
Script that can run a check and perform an action if the check fails
/root/commandchecker.sh (get from
http://downloads.rimuhosting.com/commandchecker.sh)
/root/istomcatrunning.sh:
code:
#!/bin/bash
tomcatpids=`ps axf --width=200 | grep "\-D[j]ava.endorse" | sed 's/^ *//g' | cut -d ' ' -f 1`
if [ -z "$tomcatpids" ]; then
# return a 'fail' code
return 1
fi
return 0
/root/restarttomcat.sh:
Code:
#!/bin/bash
# try to be nice
/etc/rc.d/init.d/tomcat stop
# but sometimes more drastics measures are necessary if things are not responding
kill -9 `ps axf --width=200 | grep "\-D[j]ava.endorse" | sed 's/^ *//g' | cut -d ' ' -f 1`
/etc/rc.d/init.d/tomcat start
cron job.
/etc/cron.d/monitortomcat.cron
0-59/5 * * * * root /root/commandchecker.sh --email
youremail@example.com --command "/root/istomcatrunning.sh" --onfail "/root/restarttomcat.sh" --triggeractionafternfails 3 --checkname tomcatcheck > /dev/null"
The error I get when script run:
/root/istomcatrunning.sh: line 5: return: can only `return' from a function or sourced script
/root/istomcatrunning.sh: line 7: return: can only `return' from a function or sourced script
failed command result match (25 recently) for '/root/istomcatrunning.sh' expecting ''. recode=1
taking some action: /root/restarttomcat.sh
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]
startup taking too long, not getting a response on
The UNIX and Linux Forums - Learn UNIX and Linux from Experts, giving up
command result mismatch for /root/istomcatrunning.sh, sending email
Could anyone help to fingure out what wrong with the script please?
Thx a lot.
