HyperLedger Fabric 1.4.4 raft共识集群搭建

## 前言 ##

因为`HyperLedger Fabric`后面的版本会将`kafka`共识抛弃，所以特此记录搭建`raft`共识集群流程。  
相比较于`kafka共识集群`，`raft共识集群`的搭建流程更为简化。  
本文只记录了和搭建`kafka共识集群`中步骤不一样的部分，所以可能需要先看一下我的另一篇博客。

## 流程 ##

### 修改`configtx.yaml`文件 ###

因为我这里是3个`orderer`节点作为排序，并且只有一个`Org`，所以修改`configtx.yaml`文件，将`SampleMultiNodeEtcdRaft`的内容修改为如下：

SampleMultiNodeEtcdRaft:
            <<: *ChannelDefaults
            Capabilities:
                <<: *ChannelCapabilities
            Orderer:
                <<: *OrdererDefaults
                OrdererType: etcdraft
                EtcdRaft:
                    Consenters:
                    - Host: orderer.example.com
                      Port: 7050
                      ClientTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/server.crt
                      ServerTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/server.crt
                    - Host: orderer2.example.com
                      Port: 7050
                      ClientTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer2.example.com/tls/server.crt
                      ServerTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer2.example.com/tls/server.crt
                    - Host: orderer3.example.com
                      Port: 7050
                      ClientTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer3.example.com/tls/server.crt
                      ServerTLSCert: crypto-config/ordererOrganizations/example.com/orderers/orderer3.example.com/tls/server.crt
                Addresses:
                    - orderer.example.com:7050
                    - orderer2.example.com:7050
                    - orderer3.example.com:7050
    
                Organizations:
                - *OrdererOrg
                Capabilities:
                    <<: *OrdererCapabilities
            Application:
                <<: *ApplicationDefaults
                Organizations:
                - <<: *OrdererOrg
            Consortiums:
                SampleConsortium:
                    Organizations:
                    - *Org1

## 生成创世区块 ##

因为排序方式的改变，所以生成创世区块的命令修改为如下：  
`configtxgen -profile SampleMultiNodeEtcdRaft -channelID $SYS_CHANNEL -outputBlock ./channel-artifacts/genesis.block`

## 启动容器 ##

启动容器的时候将`yaml`文件中的`kafka`和`zookeeper`相关的内容都去掉即可。
