@mirabilos will fix that and drop you reply! :) 👍
Hi Miglen,
Great script. I also saw that the script does not wait for tomcat to be fully started up.
Could you change this?
Thanks in advance,
Joeri
Nice script! Three minor improvements to make, if you want.
Pass java options in
Define at the top where the properties section the amount of memory and heap to use.
JAVA_OPTS="-server -Xms256m -Xmx256M -XX:MaxPermSize=512m"
The command to start then becomes
/bin/su $TOMCAT_USER -c "$CATALINA_HOME/bin/startup.sh $JAVA_OPTS"
Print Dots instead of a New Line
I don't want screen or logs cluttered with the same information repeated, just preference. This will print
waiting for processes to exit.....................
killing processes didn't stop after 20 seconds
count=0;
echo -n -e "\n\e[00;31mwaiting for processes to exit\e[00m";
until [ `ps -p $pid | grep -c $pid` = '0' ] || [ $count -gt $kwait ]
do
echo -n -e ".";
sleep 1
let count=$count+1;
done
Setup Init Info
This will configure the default run level on ubuntu so it will restart automatically when machine starts
update-rc.d tomcat defaults
### BEGIN INIT INFO
# Provides: tomcat7
# Required-Start: $network
# Required-Stop: $network
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Start/Stop Tomcat server
### END INIT INFO
I added the following features to my gist here (I don't know how to 'push') https://gist.github.com/arberg/af06bf99a31675e48bf9cb9d5ffe789c
Added wait for start using curl check.
Added max wait duration configuration at top.
Use sudo with keep environment to get JAVA_HOME across instead of su.
Repeated stop if first fails with connection refused.
Ability for jvm flags.
Had some issues with tomcat_pid() matching wrong processes (like tailing tomcat logs). This fixed it for me
https://gist.github.com/rougesheep/2e66e5b7637d3f0b6feba0949d898554
I found this script is very useful in practical. Great Job. Keep it UP!
I added "-l" parameter to line 64 /bin/su -l $TOMCAT_USER -c $CATALINA_HOME/bin/startup.sh to load user environment
update tomcat_pid() to work on OS X
tomcat_pid() {
echo ps -fe | grep $CATALINA_BASE | grep -v grep | awk '{ print $2 }'
}
The script does a potential infinite wait on startup. I think the script should fail if tomcat does not start up before a timeout.
For example it happened that I have configured Tomcat on a port different than 8080, set the boot script to run on startup without changing the port in the script and then I got locked out of my server, because chkconfig put Tomcat before even ssh :-(
Suppose Tomcat does not start for a reason someday (e.g. problems with file system, permission, etc), it won't probably open the port and the entire boot sequence may be at jeopardy if the script loops on curl
ing the port
Hey,Thank for your perfect script.
But I have found a bug:
You get the tomcat pid by
echo
ps -fe | grep $CATALINA_BASE | grep -v grep | tr -s " "|cut -d" " -f2
But if I have opened a conf file in the $CATALINA_BASE ,the command will return more than one result.
you can change it to
echo
ps -ef | grep "org.apache.catalina.startup.Bootstrap start" | grep $CATALINA_BASE | grep -v grep | tr -s " "|cut -d" " -f2
Thank you!
(My English is not good,if inappropriate,please understand.)
Hello, Thanks for your script.
One thing i want to check some.
tomcat_pid method
echo ps -fe | grep $CATALINA_BASE | grep -v grep | tr -s " "|cut -d" " -f2
When i stop tomcat, sometimes process shows more then 1. so It cause many pid lists.
So, I recommand tomcat_pid scripts change below
echo ps -fe | grep $CATALINA_BASE | grep -v grep | grep -v stop | tr -s " "|cut -d" " -f2
Thank you!
The tomcat status
function should be exit 3
instead of return 3
.
return
has nothing to do with exit codes required for application/scripts.
thanx for the script!
This script does not wait until the server is fully started up and ready to serve, and as such, unsafe.
