geth命令开启rpc
geth --datadir /apps/ethereum/etherdata/ --rpc --rpcapi "db,eth,net,web3" --networkid 15 --identity "alle1nNode" --rpcport 8545 --port 30303 console
注：出于安全考虑，接口默认开放API子集，通过相应参数可以进行配置。
1、调用RPC接口
# 查看账户信息
curl -X POST -H "Content-Type":application/json --data {"jsonrpc":"2.0", "method":"eth_accounts","params":[],"id":67} 172.25.0.10:8545
# 查看账户余额
curl -X POST -H "Content-Type":application/json --data {"jsonrpc":"2.0", "method":"eth_getBalance","params":["0xde1e758511a7c67e7db93d1c23c1060a21db4615","latest"],"id":67} 172.25.0.10:8545
