[区块链]3 以太坊 geth 账户创建、密码、解锁

账户操作命令

（1）创建账户

查看此节点下的所有账户：

eth.accounts

（2）查看块高

eth.blockNumber

（3）创建账户

注意：创建账户需要用 pesonal 角色，其中参数为密码：

> personal.newAccount('123456')
"0xf09dca9e10f3f1d0adfe9af7beeeb579c1d1dd37"
> personal.newAccount('abcdef')
"0x64b3085cd5a4c2ce7456b3ded2fa250545de4de1"
> eth.accounts
["0xd7ec36444d13cc079eb116b4f2602cffcdc9adee", "0xf09dca9e10f3f1d0adfe9af7beeeb579c1e7456b3ded2fa250545de4de1"]

 不建议上述，会暴露密码，推荐使用第二种方式

> personal.newAccount()
Passphrase: 
Repeat passphrase: 
"0xf6c677017eb036f984cbf590e5dde030d1fe8df1"
