Hello, we're just starting to implement a Zookeeper where I work on a Red
Hat system.
We've set everything up and it starts up just fine. The only issue is that
the process is run by the root user.
sudo /etc/init.d/zookeeper start
I have a zookeeper user ready to go. The init script we have makes a java
call to start up the process.
start)
echo -n "Starting zookeeper ... "
if [ -f $ZOOPIDFILE ]; then
if kill -0 `cat $ZOOPIDFILE` > /dev/null 2>&1; then
echo $command already running as process `cat $ZOOPIDFILE`.
exit 0
fi
fi
nohup $JAVA "-Dzookeeper.log.dir=${ZOO_LOG_DIR}"
"-Dzookeeper.root.logger=${ZOO_LOG4J_PROP}" \
-cp "$CLASSPATH" $JVMFLAGS $ZOOMAIN "$ZOOCFG" > "$_ZOO_DAEMON_OUT"
2>&1 < /dev/null &
if [ $? -eq 0 ]
then
if /bin/echo -n $! > "$ZOOPIDFILE"
then
sleep 1
echo STARTED
else
echo FAILED TO WRITE PID
exit 1
fi
else
echo SERVER DID NOT START
exit 1
fi

I've looked in to editing this script, including /etc/init.d/functions and
calling the daemon function to run the start as user zookeeper. But this
forks the process and the PID file is updated with the daemon process, not
the zookeeper process. This causes the stop feature to fail.
Before I go about re-writing this init script, I figure someone else must
have a proper way of starting this up as a non-root user.
