Hi, Thank you very much for your post. It helps me a lot.
Now I encountered a problem. When I try CPU Mining, it shows a 500 Internal Server Error. How to solve it?

[2018-04-28 23:39:50] Binding thread 0 to cpu 0
[2018-04-28 23:39:50] Binding thread 1 to cpu 1
[2018-04-28 23:39:50] 2 miner threads started, using 'scrypt' algorithm.
[2018-04-28 23:39:50] HTTP request failed: The requested URL returned error: 500 Internal Server Error
[2018-04-28 23:39:50] json_rpc_call failed, retry after 30 seconds

My Bitcoin.conf is:

server=1
gen=0
rpcuser=rpcuser
rpcpassword=111111
rpcallowip=127.0.0.1
rpcport=8962
listen=1

Hi, you need to specify sha256d as mining algorithm, you were using scrypt instead. Try add "-a sha256d" to cpuminer command line.
