I have a jar file which I am running like this in my Ubuntu 10.10 and then it starts my exhibitor server in the background -
nohup java
-jar /pekooz/exhibitor-1.5.1/lib/exhibitor-1.5.1-jar-with-dependencies.jar
-c file --fsconfigdir /opt/exhibitor/conf
--hostname machineA > exhibitor.out &
Now I am trying to use crontab to check whether my exhibitor server is running or not. If it is not running, then start it again so I decided to use crontab and I did the below steps to setup crontab -
- Created a new crontab by running
crontab -e. Added this line to the file that just opened
*/5 * * * * pgrep -f exhibitor || nohup java -jar /pekooz/exhibitor-1.5.1/lib/exhibitor-1.5.1-jar-with-dependencies.jar -c file --fsconfigdir /opt/exhibitor/conf --hostname machineA > exhibitor.outSave the file and exit the editor.
So for the testing purpose to see whether my crontab is working or not, I started my exhibitor server like this firstly -
$ nohup java
-jar ./exhibitor-1.5.1/lib/exhibitor-1.5.1-jar-with-dependencies.jar
-c file --fsconfigdir /opt/exhibitor/conf
--hostname machineA > exhibitor.out &
[1] 14401
$ nohup: ignoring input and redirecting stderr to stdout
And then I setup my crontab as shown above with the steps. After that I did kill -9 14401 so that I can see whether my exhibitor server is getting restarted automatically by crontab or not. And apparently, they didn't get started up and I don't see any error as well. Below is the log -

Is java in /usr/bin directory? The crontab has a minimal PATH by default. You may have to set JAVA_HOME and PATH in your crontab:
*/5 * * * * JAVA_HOME=/opt/java/latest;export JAVA_HOME;
PATH=$PATH:$JAVA_HOME/bin;
pgrep -f exhibitor || nohup java
-jar /pekooz/exhibitor-1.5.1/lib/exhibitor-1.5.1-jar-with-dependencies.jar
-c file --fsconfigdir /opt/exhibitor/conf --hostname machineA > exhibitor.out

Yes java is in/usr/bin. This is what I got/usr/bin/javaafter I didwhich java. And what is this/opt/java/latestin your suggestion.

Some bizarre installations put java in strange places. Not familiar with Ubuntu, so that was partially a shot in the dark.

Is java in /usr/bin directory? The crontab has a minimal PATH by default. You may have to set JAVA_HOME and PATH in your crontab:
*/5 * * * * JAVA_HOME=/opt/java/latest;export JAVA_HOME;
PATH=$PATH:$JAVA_HOME/bin;
pgrep -f exhibitor || nohup java
-jar /pekooz/exhibitor-1.5.1/lib/exhibitor-1.5.1-jar-with-dependencies.jar
-c file --fsconfigdir /opt/exhibitor/conf --hostname machineA > exhibitor.out

Some bizarre installations put java in strange places. Not familiar with Ubuntu, so that was partially a shot in the dark.

You might want to look into using upstart to launch your process: you can tell upstart to "respawn" your program if it dies.

@glennjackman I am running Ubuntu 10.10 which has no support whatsoever. I have already tried and some of the commands doesn't work.

Then perhaps a simple wrapper:
sh -c 'while true; do java -jar ...; done'– Patrick

@Patrick I was not able to understand what you said? :(

He's saying that whatever you're using to run the exhibitor app, wrap it in a while true block.
sh -c 'while true; do java -jar ...; done'. This will act like a guard which will constantly keep restarting exhibitor every time it dies.– slm♦
