控制台

控制台能以IPC的方式直接连接区块链节点进程。使用控制台，能直接查看到区块链上的信息。若需要更直观更全面的区块链数据展现，请使用FISCO-BCOS的区块链浏览器。

登陆控制台

连接节点的data目录下的geth.ipc文件。

ethconsole /mydata/node0/data/geth.ipc

登录成功，可看到successful字样。

Connecting to node at /mydata/nodedata-1/data/geth.ipc

查看区块

如查看块高为2的区块

web3.eth.getBlock(2,console.log)

可得到相应的区块信息
