pause

5 创建账号
服务器a,b都创建

5.1 账号personal.newAccount()

etha:
xwx7712test
"0x1965ecd38411fa98fec15b188f402c0f6d8115b9"

ethb
xwx7712test
"0x12d5ba84cfef799820baa863ecf7a37e90c08947"

6 节点admin.nodeInfo

etha
enode://38135769c6c90f3d800da70328952274d5d44b469825b0538f75cb38ba5d56fef7cb5177d6c6fe25728f209084ae9f0bdf7653570121a6fce051d98e22323006@0.0.0.0:30303
