I am using geth 1.7.3 stable, I have tried the following commands.

geth --rinkeby --ws --wsport=8546 --wsorigins="*" --datadir=$HOME/.rinkeby --cache=512 --rpc --rpcapi="personal,eth,network" --rpcport=8545 --fast --bootnodes=enode://a24ac7c5484ef4ed0c5eb2d36620ba4e4aa13b8c84684e1b4aab0cebea2ae45cb4d375b77eab56516d34bfbd3c1a833fc51296ff084b770b94fb9028c4d25ccf@

in the first begining

it continuously gives me this information

INFO [01-01|12:39:08] Imported new state entries   

wondering the continuous message is meaning the node is at the sync?

during the time, i used the metamask to connect the localhost:8545, but it can't connect to it, anything wrong with my commands?

  • "but it can't connect to it" Do you see an error message? If so, what is it? If not, how do you know MetaMask can't connect? – smarx Jan 1 '18 at 12:57

Per https://support.metamask.io/kb/article/2-using-a-local-node:

Geth needs to have a special CORS setting enabled to allow MetaMask to connect to it by default, so try starting it with this command:

`geth --rpc --rpccorsdomain="chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn"`

In your case, I would suggest just adding the --rpccorsdomain="... parameter.
