hello thanks you guys for fast and good reply's
i have some others questions ,
for bitcoin.conf what is this ?
maxconnections= i read this by default is 125 but ? What type of connections ? can someone explain wich this connections do can i upgrade this number it require a lot of hardware ?
rpcthreads= i read this by default is 4 it mean the number threads of CPU who bitcoind will be allowed to use ?
if i have online website and in the same server of website i have the daemon with rpcallow=127.0.0.1 and in php file of website rpcip=127.0.0.1
on my online website domain will be able to do transactions without problems or i have to tell the ipv4 for rpcallow ?
there's a differences between
bitcoin-cli ./bitcoin-cli
everytime when i want to run bitcoid will be good with this codes ?
./bitcoind -daemon -datadir=folder/folder/folder/folder
and for bitcoin-cli
./bitcoin-cli -datadir=............................ getinfo
./bitcoin-cli -datadir=............................ help
or it will be ok only
?
