If you used the default installation path of /var/EZSTEEM, try this command:

screen -dmSL myTest /var/EZSTEEM/steem/programs/steemd/steemd

the -dmSL means : detach with a new screen, allow a session name (myTest in this case, you can use whatever) and log stderr and stdout at ~/screenlog.0

You should now be able to exit your PuTTY session leaving it running in the background.

When you log back in again, use this command to bring it to the foreground.

screen -x myTest

You can also check the log using your favorite text editor or just watch it with tail

tail -f ~screenlog.0
