need account on steemit.com for mining ?
No. Just follow one of the mining guide and you will be fine.
ok, done, but miner stuck with these messages :
2672679ms th_a thread.cpp:95 thread ] name:ntp tid:140487625266944

it's normal ?
Looks like maybe you need to add seed nodes to your config.ini
Try:
seed-node = steemseed.dele-puppy.com:2001
seed-node = steem-seed1.abit-more.com:2001
seed-node = steem-id.altexplorer.xyz:2001
seed-node = steemd.pharesim.me:2001
seed-node = 213.167.243.223:2001
seed-node = 212.117.213.186:2016
seed-node = 185.82.203.92:2001
seed-node = 52.74.152.79:2001
seed-node = 104.236.82.250:2001
seed-node = seed.steemd.com:34191
seed-node = seed.steemed.net:2001
seed-node = steem.seeds.quisquis.de:2001
Also, specify -t followed by the number of threads when starting steemd e.g. steemd --rpc-endpoint -t4
