geth搭建私有链,remix连接出现的问题

首先使用单引号geth --datadir ./data/00 --networkid 314590  --port 61910 --rpc --rpcapi 'web3,eth,debug' --rpccorsdomain '* --rpcport 8200 console

使用remix无法连接

然后换成双引号geth --datadir ./data/00 --networkid 314590  --port 61910 --rpc --rpcapi "web3,eth,debug" --rpccorsdomain "*" --rpcport 8200 console

Web3 Provider  处填入如下,http://127.0.0.1:8200,显示can't  detect network.然后creation of SimpleStorage pending

最后把rpcapi中的 debug改为net   geth --datadir ./data/00 --networkid 314590  --port 61910 --rpc --rpcapi "web3,eth,net" --rpccorsdomain "*" --rpcport 8200 console

可以连接了

上面的错误是创世区块genesis.json中的参数gasLimit 设置的太小导致.

module.exports = {
    networks: {
        live: {
            host: "localhost",
            port: 8200,
            network_id: 314590, // 匹配任何network id
            gas: 500000  //设置小一点
         }
    }
};
