I have a custom service managed by an init script in /etc/init.d and, after upgrading to CentOS 7, with systemd, 'systemctl restart service' is not working correctly. I need to execute two times 'systemctl restart service' to make it restart (the first time, it just stops it, it does not start it after stopping it). I don't know exactly what's happening but if I stop the service using '/etc/init.d/service stop', the process is killed and is not shown in 'ps aux', but 'systemctl status service' says it is "active".
This is my init script in /etc/init.d:
#!/bin/bash
#
# Startup script for the service
# chkconfig: 2345 80 20
# description: a service
PID_FILE=/var/run/pidfile.pid
LOG_FILE=/var/log/serviceslogs
#Necessary environment variables
export JAVA_HOME="/usr/java/latest"
#export JAVA_HOME="/root/java-8-oracle"
if test \! -d "${JAVA_HOME}"; then
echo "$0: the JAVA_HOME exported value is not defined correctly"
exit 2
fi

start() {
if [ -e $PID_FILE ]
then
checkpid `cat /var/run/pidfile.pid`
res=$?
if [ $res -eq 0 ]
then
echo "Standalone service is already running!"
return;
fi
fi
$JAVA_HOME/bin/java blablablablabla > $LOG_FILE 2>&1 & echo $! > $PID_FILE
echo $! > $PID_FILE
echo "Starting Standalone service "
}
stop() {
echo "Shutting down Standalone service: "
checkpid `cat /var/run/pidfile.pid`
res=$?
if [ $res -eq 0 ]
then
kill -9 `cat /var/run/pidfile.pid`
rm `cat /var/run/pidfile.pid`
echo "Standalone service stopped."
else
echo "Standalone service is not running!"
fi
}
status() {
checkpid `cat /var/run/pidfile.pid`
res=$?
if [ $res -eq 0 ]
then
echo "Standalone service is running."
else
echo "Standalone service is stopped."
fi
}
case "$1" in
start)
start
;;
stop)
stop
;;
restart)
stop
start
;;
status)
status
;;
*)
echo "Usage: service {start|stop|restart|status}"
exit 1
esac
And this is my .service file in /usr/lib/systemd/system:

Hopping somebody can help. Thanks.
