1.三大组件

这是EOS官网的组件架构关系图，描述了不同组件之间的关系：

nodeos - 服务器端的区块链节点组件
keosd - 钱包管理组件
cleos - 操作 nodeos 和 keosd 的命令行工具

2.创建和管理钱包

2.1 创建钱包

yuyangdeMacBook-Pro:~ yuyang$ cd /Users/yuyang/eos/build/programs/cleos 
yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet list
"/usr/local/bin/keosd" launched
Wallets:
[]

可以看到keosd默认启动，并且还没有钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet create
Creating wallet: default
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.
"PW5KQwfoDJDUUTTEdZzTpSHYfmvSWxL23jefVHLi6UL74Uw9em6WA"

创建了一个钱包，默认名为default.wallet，记下密码用于后面解锁钱包，keosd将钱包文件存储在~/eosio-wallet文件夹中

查看钱包，*表示该钱包文件处于解锁状态

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet list
Wallets:
[
  "default *"
]

2.2 创建自定义名称钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet create -n yuyang
Creating wallet: yuyang
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.
"PW5J3F77veqpEkCKfc6GXCjj1eDXzWGVPiNjoFZNsQD7TvcT3X31V"

-n后面跟钱包名称

查看钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet list
Wallets:
[
  "default *",
  "yuyang *"
]

2.3 锁定钱包

锁定默认钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet lock
Locked: default

查看钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet list
Wallets:
[
  "default",
  "yuyang *"
]

可以看到default没有*号，说明已上锁

锁定指定名称钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet lock -n yuyang
Locked: yuyang

查看钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet list
Wallets:
[
  "default",
  "yuyang"
]

两个钱包都已锁定

2.4 解锁钱包

解锁默认钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet unlock
password: Unlocked: default

在password提示出现时复制对应的钱包密码

查看钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet list
Wallets:
[
  "default *",
  "yuyang"
]

可以看到default钱包已解锁

解锁指定名称钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet unlock -n yuyang
password: Unlocked: yuyang

在password提示出现时复制对应的钱包密码

查看钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet list
Wallets:
[
  "default *",
  "yuyang *"
]

两个钱包都已解锁

也可以直接在解锁时加入--password参数，然后输入钱包密码进行解锁。不过这样会导致钱包密码会显示在console记录上

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet unlock -n yuyang --password PW5J3F77veqpEkCKfc6GXCjj1eDXzWGVPiNjoFZNsQD7TvcT3X31V
Unlocked: yuyang

查看钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet list
Wallets:
[
  "default *",
  "yuyang *"
]

3.Keosd

因为接下来的操作涉及到另一个组件keosd，所以这里先插入讲解下。

keosd位于eos/build/programs/keosd下，作用是存储私钥，以便cleos用以签署交易并发送到区块链中。keosd在本机运行，并且将私钥存储在本地。

keosd会随着cleos自动启动。

3.1 自动锁定

keosd会在没有钱包指令的15分钟后自动锁定钱包，可以在~/eosio-wallet/config.ini中进行时长修改。可以设置一个超大数来取消这项功能。如果设为0，将会导致钱包永久锁定。

3.2 手动开启

yuyangdeMacBook-Pro:nodeos yuyang$ cd /Users/yuyang/eos/build/programs/keosd 
yuyangdeMacBook-Pro:keosd yuyang$ keosd

3.3 停止Keosd

停止keosd最有效的方法是找到keosd的进程，然后发送结束指令。需要注意的是cleos会自动开启keosd，这可能会导致其多个实例在运行。使用以下指令找到并结束所有keosd实例。

$ pgrep keosd
3178
24991
$ pkill keosd

3.4 其他选项

yuyangdeMacBook-Pro:keosd yuyang$ keosd --help

                                        for library users

3.5 重启后操作钱包

现在另开一个命令窗口，停止keosd

yuyangdeMacBook-Pro:keosd yuyang$ pgrep keosd
827
yuyangdeMacBook-Pro:keosd yuyang$ pkill keosd

回到cleos命令窗口，查看钱包

yuyangdeMacBook-Pro:nodeos yuyang$ cleos wallet list
"/usr/local/bin/keosd" launched
Wallets:
[]

由于cleos会检查keosd实例是否在运行，如果没有，则会启动其实例。

在操作钱包文件或者查看钱包列表前，需要先打开钱包文件。当我们停止keosd时，钱包文件会被上锁。当keosd重新启动后，钱包文件并未打开。输入以下命令打开并显示默认钱包default.wallet

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet open
Opened: default
yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet list
Wallets:
[
  "default"
]

打开指定名称钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet open -n yuyang
Opened: yuyang
yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet list
Wallets:
[
  "default",
  "yuyang"
]

4.生成并导入私钥对

生成两对公钥/私钥对

yuyangdeMacBook-Pro:cleos yuyang$ cleos create key
Private key: 5HqW8BxjUgNgWJQNNnvMVtLWRrwqmzDXnH5kZjFq5RmmTxUGvLx
Public key: EOS54RjRpGQbNhmz8gKspmH4DwPCXd6rhPy3U1UGZzjoxssAJALUM
yuyangdeMacBook-Pro:cleos yuyang$ cleos create key
Private key: 5JahG29Q57gVHjtWK2YD614Fodfb6Dr72zvN3oCKLGKJaEvFoew
Public key: EOS8GJ9YdSKcSfFcUXYff8MU4ifQLFiHGBNZ8VkSdDT7wcjnnL4gN

现在我们有两队密钥对了，此时，他们只是随意生成的密钥对，并且本身没有任何权限。

下一步，我们将两组密钥对中的私钥导入钱包。

现在先解锁default.wallet钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet list
Wallets:
[
  "default",
  "yuyang"
]
yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet unlock --password PW5KQwfoDJDUUTTEdZzTpSHYfmvSWxL23jefVHLi6UL74Uw9em6WA
Unlocked: default
yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet list
Wallets:
[
  "default *",
  "yuyang"
]

导入两个私钥到default.wallet钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet import --private-key 5HqW8BxjUgNgWJQNNnvMVtLWRrwqmzDXnH5kZjFq5RmmTxUGvLx
imported private key for: EOS54RjRpGQbNhmz8gKspmH4DwPCXd6rhPy3U1UGZzjoxssAJALUM
yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet import --private-key 5JahG29Q57gVHjtWK2YD614Fodfb6Dr72zvN3oCKLGKJaEvFoew
imported private key for: EOS8GJ9YdSKcSfFcUXYff8MU4ifQLFiHGBNZ8VkSdDT7wcjnnL4gN

可以看到，导入某个私钥成功后，会显示对应的公钥

现在查看所有解锁状态下钱包中的公钥

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet keys
[
  "EOS54RjRpGQbNhmz8gKspmH4DwPCXd6rhPy3U1UGZzjoxssAJALUM",
  "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV",
  "EOS8GJ9YdSKcSfFcUXYff8MU4ifQLFiHGBNZ8VkSdDT7wcjnnL4gN"
]

除了我们刚才生成的密钥，还多了一个EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV公钥。这个公钥是~/Library/Application Support/eosio/nodeos/config中的nodeos组件配置文件config.ini的默认值。

增加default.wallet钱包密码的参数，查看default.wallet钱包中的公私钥对

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet private_keys --password PW5KQwfoDJDUUTTEdZzTpSHYfmvSWxL23jefVHLi6UL74Uw9em6WA
[[
    "EOS54RjRpGQbNhmz8gKspmH4DwPCXd6rhPy3U1UGZzjoxssAJALUM",
    "5HqW8BxjUgNgWJQNNnvMVtLWRrwqmzDXnH5kZjFq5RmmTxUGvLx"
  ],[
    "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV",
    "5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3"
  ],[
    "EOS8GJ9YdSKcSfFcUXYff8MU4ifQLFiHGBNZ8VkSdDT7wcjnnL4gN",
    "5JahG29Q57gVHjtWK2YD614Fodfb6Dr72zvN3oCKLGKJaEvFoew"
  ]
]

我们也为yuyang.wallet导入两组密钥对

先解锁yuyang.wallet钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet unlock -n yuyang --password PW5J3F77veqpEkCKfc6GXCjj1eDXzWGVPiNjoFZNsQD7TvcT3X31V
Unlocked: yuyang
yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet list
Wallets:
[
  "default *",
  "yuyang *"
]

生成两对公钥/私钥对

yuyangdeMacBook-Pro:cleos yuyang$ cleos create key
Private key: 5Kje821Tq2yh1MuVrPA4fxDXMXyhktRAhMEJp1rZPd58T3MXAB7
Public key: EOS6JCDcFJbkDBQuP8f5K9ELbDPMgtPo2dNU12ezNKAHi21SXgvSL
yuyangdeMacBook-Pro:cleos yuyang$ cleos create key
Private key: 5Jf83kKqgEATTu8vfhvwHJxV5SfJU6emKXCCvA3zDWVBXjYowaY
Public key: EOS7ZqcVEdGDmzKmhnCfjK3x9wzjqDd3mmv3hXtqWMVa1keVoU1Nc

指定钱包名称参数，导入两个私钥到yuyang.wallet钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet import --private-key 5Kje821Tq2yh1MuVrPA4fxDXMXyhktRAhMEJp1rZPd58T3MXAB7 -n yuyang
imported private key for: EOS6JCDcFJbkDBQuP8f5K9ELbDPMgtPo2dNU12ezNKAHi21SXgvSL
yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet import --private-key 5Jf83kKqgEATTu8vfhvwHJxV5SfJU6emKXCCvA3zDWVBXjYowaY -n yuyang
imported private key for: EOS7ZqcVEdGDmzKmhnCfjK3x9wzjqDd3mmv3hXtqWMVa1keVoU1Nc

现在查看所有解锁状态下钱包中的公钥

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet keys
[
  "EOS54RjRpGQbNhmz8gKspmH4DwPCXd6rhPy3U1UGZzjoxssAJALUM",
  "EOS6JCDcFJbkDBQuP8f5K9ELbDPMgtPo2dNU12ezNKAHi21SXgvSL",
  "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV",
  "EOS7ZqcVEdGDmzKmhnCfjK3x9wzjqDd3mmv3hXtqWMVa1keVoU1Nc",
  "EOS8GJ9YdSKcSfFcUXYff8MU4ifQLFiHGBNZ8VkSdDT7wcjnnL4gN"
]

可以看到又多了两个公钥

查看yuyang.wallet钱包中的公私钥对，注意这里需要传两个参数，钱包密码和钱包名称，如果不传钱包名称，eosio会认为你查询的是默认钱包default.wallet的公私钥对

yuyangdeMacBook-Pro:cleos yuyang$ cleos wallet private_keys --password PW5J3F77veqpEkCKfc6GXCjj1eDXzWGVPiNjoFZNsQD7TvcT3X31V -n yuyang
[[
    "EOS6JCDcFJbkDBQuP8f5K9ELbDPMgtPo2dNU12ezNKAHi21SXgvSL",
    "5Kje821Tq2yh1MuVrPA4fxDXMXyhktRAhMEJp1rZPd58T3MXAB7"
  ],[
    "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV",
    "5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3"
  ],[
    "EOS7ZqcVEdGDmzKmhnCfjK3x9wzjqDd3mmv3hXtqWMVa1keVoU1Nc",
    "5Jf83kKqgEATTu8vfhvwHJxV5SfJU6emKXCCvA3zDWVBXjYowaY"
  ]
]

正常返回了yuyang.wallet钱包中的公私钥对

5. Nodeos

因为接下来创建账号需要启动nedeos，所以先了解下nedeos

官方文档Local Single-node Testnet

nedeos位于build/programs/nodeos文件夹中，使用以下命令启动单节点区块链

cd build/programs/nodeos
./nodeos -e -p eosio --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin

成功后开始产出区块

1575001ms thread-0   chain_controller.cpp:235      _push_block          ] initm #1 @2017-09-04T04:26:15  | 0 trx, 0 pending, exectime_ms=0
1575001ms thread-0   producer_plugin.cpp:207       block_production_loo ] initm generated block #1 @ 2017-09-04T04:26:15 with 0 trxs  0 pending
1578001ms thread-0   chain_controller.cpp:235      _push_block          ] initc #2 @2017-09-04T04:26:18  | 0 trx, 0 pending, exectime_ms=0
1578001ms thread-0   producer_plugin.cpp:207       block_production_loo ] initc generated block #2 @ 2017-09-04T04:26:18 with 0 trxs  0 pending
...
eosio generated block 046b9984... #101527 @ 2018-04-01T14:24:58.000 with 0 trxs
eosio generated block 5e527ee2... #101528 @ 2018-04-01T14:24:58.500 with 0 trxs
...

此时，eosio作为一个单独的区块生产者

5.1 建议步骤

nedeos的配置文件位于~/Library/Application Support/eosio/nodeos/config文件夹中，可以通过编辑该文件，以便直接使用nedeos命令生产区块。

修改或新增以下内容：

  # Enable production on a stale chain, since a single-node test chain is pretty much always stale
    enable-stale-production = true
    # Enable block production with the testnet producers
    producer-name = eosio
    # Load the block producer plugin, so you can produce blocks
    plugin = eosio::producer_plugin
    # As well as API and HTTP plugins
    plugin = eosio::chain_api_plugin
    plugin = eosio::http_plugin
   # This will be used by the validation step below, to view history
    plugin = eosio::history_api_plugin

现在可以直接使用nedeos命令生产区块了

yuyangdeMacBook-Pro:nodeos yuyang$ nodeos

nedeos将区块数据存储在文件~/Library/Application Support/eosio/nodeos/data中

6. 创建账户

6.1 准备工作

我们使用cleos发送指令给nodeos来创建账户并提交到区块链上，所以需要启动一个测试用的单节点

我们需要keosd和nodeos都处于运行状态。它们当前都使用的是同一个端口号8888。如果只想启动nodeos，我们需要将keosd的端口号改为8899，有两种方法可以进行修改：

编辑keosd的配置文件~/eosio-wallet/config.ini，将http-server-address属性改为http-server-address = 127.0.0.1:8899
启动keosd时加入--http-server-address=localhost:8899参数

注意：第一种方式已证明无效。如果想使用这种方式，需要将~/eosio-wallet/config.ini拷贝到其他文件夹，名称不变。此时修改其中的地址，然后在启动keosd时指定配置文件位置。例如：keosd --config-dir /Users/yuyang/eosio-wallet/config。config.ini文件位于/Users/yuyang/eosio-wallet/config文件夹中。

现在重新启动keosd，使用命令参数的方式指定端口号：

yuyangdeMacBook-Pro:keosd yuyang$ pgrep keosd
808
yuyangdeMacBook-Pro:keosd yuyang$ pkill keosd
yuyangdeMacBook-Pro:keosd yuyang$ keosd --http-server-address=localhost:8899
2730059ms thread-0   wallet_plugin.cpp:41          plugin_initialize    ] initializing wallet plugin
2730060ms thread-0   http_plugin.cpp:247           plugin_initialize    ] configured http to listen on localhost:8899
2730060ms thread-0   http_plugin.cpp:285           plugin_startup       ] start listening for http requests
2730060ms thread-0   wallet_api_plugin.cpp:70      plugin_startup       ] starting wallet_api_plugin
2730060ms thread-0   http_plugin.cpp:325           add_handler          ] add api url: /v1/wallet/create
2730060ms thread-0   http_plugin.cpp:325           add_handler          ] add api url: /v1/wallet/get_public_keys
2730060ms thread-0   http_plugin.cpp:325           add_handler          ] add api url: /v1/wallet/import_key
2730060ms thread-0   http_plugin.cpp:325           add_handler          ] add api url: /v1/wallet/list_keys
2730060ms thread-0   http_plugin.cpp:325           add_handler          ] add api url: /v1/wallet/list_wallets
2730060ms thread-0   http_plugin.cpp:325           add_handler          ] add api url: /v1/wallet/lock
2730060ms thread-0   http_plugin.cpp:325           add_handler          ] add api url: /v1/wallet/lock_all
2730060ms thread-0   http_plugin.cpp:325           add_handler          ] add api url: /v1/wallet/open
2730060ms thread-0   http_plugin.cpp:325           add_handler          ] add api url: /v1/wallet/set_timeout
2730060ms thread-0   http_plugin.cpp:325           add_handler          ] add api url: /v1/wallet/sign_transaction
2730060ms thread-0   http_plugin.cpp:325           add_handler          ] add api url: /v1/wallet/unlock

解锁default.wallet钱包。因为现在keosd已经重启并且监听端口改为了8899，所以需要新增钱包指令的url参数：

yuyangdeMacBook-Pro:cleos yuyang$ cleos --wallet-url=http://localhost:8899 wallet unlock
password: Unlocked: default

查看钱包

yuyangdeMacBook-Pro:cleos yuyang$ cleos --wallet-url=http://localhost:8899 wallet list
Wallets:
[
  "default *"
]

新开一个命令行，启动nodeos:

yuyangdeMacBook-Pro:nodeos yuyang$ nodeos

在此教程中，eosio是授权账户。在区块链上进行actions操作时，需要使用eosio的密钥进行签名。eosio的密钥位于~/Libraries/Application Support/eosio/nodeos/config/config.ini中，内容如下：

#    KEOSD:<data>       is the URL where keosd is available and the approptiate wallet(s) are unlocked (eosio::producer_plugin)
signature-provider = EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV=KEY:5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3

查看default.wallet钱包中的公钥

yuyangdeMacBook-Pro:cleos yuyang$ cleos --wallet-url=http://localhost:8899 wallet keys
[
  "EOS54RjRpGQbNhmz8gKspmH4DwPCXd6rhPy3U1UGZzjoxssAJALUM",

  "EOS8GJ9YdSKcSfFcUXYff8MU4ifQLFiHGBNZ8VkSdDT7wcjnnL4gN"
]

查看default.wallet钱包中的密钥对

yuyangdeMacBook-Pro:cleos yuyang$ cleos --wallet-url=http://localhost:8899 wallet private_keys --password PW5KQwfoDJDUUTTEdZzTpSHYfmvSWxL23jefVHLi6UL74Uw9em6WA

可以看到default.wallet钱包已经包含了eosio的密钥对了

6.2 创建账户

有关账户和权限的深入理解，可以阅读这篇文章
EOS开发(二)账户和权限说明

创建账户的格式如下：

cleos create account AUTHORIZING_ACCOUNT NEW_ACCOUNT OWNER_KEY ACTIVE_KEY

authorizing_account 新账户的创建者。在此教程中，由于我们运行的是一个单节点测试网络，所以我们拥有一个名为eosio的系统账户，因此我们使用eosio作为新账户的创建者
new_account 要创建的账户名称
owner_key 账户owner权限的公钥
active_key 账户active权限的公钥

新账户的名称需要遵循以下规则：

小于13个字符
只能包含以下字符.12345abcdefghijklmnopqrstuvwxyz

我们使用myaccount作为新账户名称，使用之前生成并导入default.wallet钱包的两个公钥EOS54RjRpGQbNhmz8gKspmH4DwPCXd6rhPy3U1UGZzjoxssAJALUM和EOS8GJ9YdSKcSfFcUXYff8MU4ifQLFiHGBNZ8VkSdDT7wcjnnL4gN作为owner权限和active权限的公钥

yuyangdeMacBook-Pro:cleos yuyang$ cleos --wallet-url=http://localhost:8899 create account eosio myaccount EOS54RjRpGQbNhmz8gKspmH4DwPCXd6rhPy3U1UGZzjoxssAJALUM EOS8GJ9YdSKcSfFcUXYff8MU4ifQLFiHGBNZ8VkSdDT7wcjnnL4gN

这里我失败了。错误也很奇怪，查了很久，试了很多方法都不行，最后删了整个eos文件夹重新git了一次代码就好了。不知道是不是我之前git的代码的版本有这个BUG。

成功提示：

6.2 查询账户

在节点查询我们刚才创建的myaccount账户：

yuyangdeMacBook-Pro:cleos yuyang$ cleos --wallet-url=http://localhost:8899 get account myaccount
permissions: 
     owner     1:    1 EOS54RjRpGQbNhmz8gKspmH4DwPCXd6rhPy3U1UGZzjoxssAJALUM
