Daemon n mining on ubuntu not work,...plz help me step by step

Hi, please see my post on page 2.
Edit: If you want to be able to enter RPC commands, you need to add
daemon=1
server=1
to your .conf file. Then when you run ./zettelkastend it will start as a background process.
For instance, once the daemon has started, enter
./zettelkastend getmininginfo
to see your hashrate and other stats.
