Fabric1.4 加密生成器：crypto-config.yaml

该文件位于/usr/local/go/src/github.com/hyperledger/fabric/fabric-samples/first-network/crypto-config.yaml下，以下是原始配置文件：

# ---------------------------------------------------------------------------
# "OrdererOrgs" - 管理orderer节点
# ---------------------------------------------------------------------------
OrdererOrgs:
  # ---------------------------------------------------------------------------
  # Orderer
  # ---------------------------------------------------------------------------
  - Name: Orderer  # Orderer的名称
    Domain: example.com  # 域名
    # ---------------------------------------------------------------------------
    # "Specs" - See PeerOrgs below for complete description
    # ---------------------------------------------------------------------------
    Specs:
      - Hostname: orderer  # hostname + Doamin的值组成Orderer节点的完整域名
# ---------------------------------------------------------------------------
# "PeerOrgs" - Definition of organizations managing peer nodes
# ---------------------------------------------------------------------------
PeerOrgs:
  # ---------------------------------------------------------------------------
  # Org1
  # ---------------------------------------------------------------------------
  - Name: Org1
    Domain: org1.example.com
    EnableNodeOUs: true  # 在MSP下生成config.yaml文件
    # ---------------------------------------------------------------------------
    # "Specs"
    # ---------------------------------------------------------------------------
    # Uncomment this section to enable the explicit definition of hosts in your
    # configuration.  Most users will want to use Template, below
    #
    # Specs is an array of Spec entries.  Each Spec entry consists of two fields:
    #   - Hostname:   (Required) The desired hostname, sans the domain.
    #   - CommonName: (Optional) Specifies the template or explicit override for
    #                 the CN.  By default, this is the template:
    #
    #                              "{
     {.Hostname}}.{
     {.Domain}}"
    #
    #                 which obtains its values from the Spec.Hostname and
    #                 Org.Domain, respectively.
    # ---------------------------------------------------------------------------
    # Specs:
    #   - Hostname: foo # implicitly "foo.org1.example.com"
    #     CommonName: foo27.org5.example.com # overrides Hostname-based FQDN set above
    #   - Hostname: bar
    #   - Hostname: baz
    # ---------------------------------------------------------------------------
    # "Template"
    # ---------------------------------------------------------------------------
    # Allows for the definition of 1 or more hosts that are created sequentially
    # from a template. By default, this looks like "peer%d" from 0 to Count-1.
    # You may override the number of nodes (Count), the starting index (Start)
    # or the template used to construct the name (Hostname).
    #
    # Note: Template and Specs are not mutually exclusive.  You may define both
    # sections and the aggregate nodes will be created for you.  Take care with
    # name collisions
    # ---------------------------------------------------------------------------
    Template:
      Count: 2
      # Start: 5
      # Hostname: {
     {.Prefix}}{
     {.Index}} # default
    # ---------------------------------------------------------------------------
    # "Users"
    # ---------------------------------------------------------------------------
    # Count: The number of user accounts _in addition_ to Admin
    # ---------------------------------------------------------------------------
    Users:
      Count: 1
  # ---------------------------------------------------------------------------
  # Org2: See "Org1" for full specification
  # ---------------------------------------------------------------------------
  - Name: Org2
    Domain: org2.example.com
    EnableNodeOUs: true
    Template:
      Count: 2
    Users:
      Count: 1

该示例配置文件指定了 OrdererOrgs 及 PeerOrgs 两个组织信息。 PeerOrgs 配置信息指定创建了 Org1 与 Org2 两个组织。每个 Org 组织使用 Template 属性下的 Count 指定创建了两个 Peer 节点， Users 属性下的 Count 指定了在各个 Peer 节点中创建一个用户。
Peer 节点的域名名称组成结构为“ peer + 起始数字0 + Domain属性的值”。例如，Org1组织中的Domain属性值为 org1.example.com ，Template.Count 属性值为2，则两个 Peer 节点的完整域名为 peer0.org1.example.com 和 peer1.org1.example.com 。

cd ./fabric-sample/first-network  # 必须进入该文件
../bin/cryptogen generate --config=./crypto-config.yaml

执行完毕后，当前文件夹下会出现一个新的文件夹：crypto-config，在该目录下就是存放刚刚生成的组织结构与身份证书。
