Ethereum_7_多节点

2018/05/08 Ethereum
  1. 第二个节点 ```

    新打开一个terminal，data路径更换

    geth –datadir data1 init genesis.json

启动时，更换端口，和第一个节点区分开（在同一台服务器时）

geth –datadir data1 –networkid 10 –port 30304 console


2. 查看信息

>以上是未添加参数 --nodiscover 时的情况，会添加到其他创世区块一样的网络中！！

1. 启动

在data上一层目录执行，否则默认会把数据写到当前用户（root）目录下

geth –datadir data0 –networkid 10 –nodiscover console

geth –datadir data1 –networkid 10 –port 30304 –nodiscover console



2. 添加网络

#将data0网络的enode，添加到data1网络中 #注意@后面的IP地址修改

admin.addPeer(“enode://4036280b66461ab79dcb98e1fb8a84934e378e6a1f3489d261804573f91bd6c9e0bda9e2ddd2f27d1ffa512bb24121732a3356cb0abeea8322f894abc5e8f6ae@127.0.0.1:30303?discport=0”)
