hi my frind
how to local solo mining (easy learn)

1 - need minimum 3 Run Bitcoin core (just make 3 bach file and copy&paste datafolder) ( if try one core . but never accepet blockchain )
2 - you need change listen port  for ever core( because not listen over than one application on a port) 8332 , 8333 ,8334 ,....
3 - you need local mining with command consol ( setgenerate true 10 ) xx block mining...
4 - you can connect to local bitcoinCore for SOLO mining  for example use "cpuminer" application

you can make .bat file for any core running easy with parameter:

"C:\Bitcoin\bitcoin-qt.exe" -conf="C:\Users\admin\AppData\Roaming\Bitcoin\ali.conf"    -datadir="C:\btc\Ali"     -port=18444
"C:\Bitcoin\bitcoin-qt.exe" -conf="C:\Users\adminAppData\Roaming\Bitcoin\reza.conf" -datadir="C:\btc\reza"   -port=18445
"C:\Bitcoin\bitcoin-qt.exe" -conf="C:\Users\admin\AppData\Roaming\Bitcoin\mamad.conf" -datadir="C:\btc\mamad" -port=18446

you need change in all file  ali.conf , or reza.conf  or mamad.conf
regtest=1
// for simple mining on local , developer starter use regtest MODE
listen=1
server=1
rpcuser=user
rpcpassword=0913
rpcconnect=127.0.0.1
daemon=1

you need changed (important) for any .conf file:

rpcport=8333
connect=localhost:18445
connect=localhost:18446

reza.conf
rpcport=8334
connect=127.0.0.1:18444
connect=127.0.0.1:18446

mamad.conf
rpcport=8335
connect=localhost:18445
connect=localhost:18444


now you can solo mining on regtest mode :

(xx == tt ) bitcointalk robot remove external link )
/cpuminer -a sha256d -o hxxp://127.0.0.1:8333  -O user:0913 --no-longpoll  --debug --coinbase-addr=Your_Bitcoin_Address

notice :  --no-longpoll
notice :  --coinbase-addr
