hyperledger fabric 1.0.5 分布式部署 （二）

环境：2台 ubuntu 16.04

角色列表

角色	IP地址	宿主端口	docker端口
peer0.org1.example.com	47.93.249.250	7051	7051
peer1.org1.example.com	47.93.249.250	7051	8051
peer0.org2.example.com	47.93.249.250	7051	9051
peer1.org2.example.com	47.93.249.250	7051	10051
cli	47.93.249.250	NULL	NULL
orderer.example.com	47.94.244.156	7050	7050

• 环境初始化

2台机器的fabric 环境初始化方法，读者参考作者之前写的一片文章：http://www.cnblogs.com/chenfool/p/8353425.html，并且确保两台机器都能够正常运行 e2e_cli 的测试程序。

在完成e2e_cli 程序的测试后，读者一定要清理环境。

./network_setup.sh down mychannel

•  分布式部署（1）

按照角色列表，首先在 47.94.244.156 机器上，目录切换到 /opt/gopath/src/github.com/hyperledger/fabric/examples/e2e_cli ，然后复制一份 docker-compose 的配置文件

cp docker-compose-cli.yaml  docker-compose-test.yaml

对 docker-compose-test.yaml 配置进行修改，修改后的内容如下

# Copyright IBM Corp. All Rights Reserved.
#
# SPDX-License-Identifier: Apache-2.0
#

version: '2'

services:

  orderer.example.com:
    extends:
      file:   base/docker-compose-base.yaml
      service: orderer.example.com
    container_name: orderer.example.com

执行以下命令，生成公私钥、证书、创世区块等，该命令执行后，会在本地生成 channel-artifacts 和 crypto-config 目录。

读者这里需要注意一下，在执行 generateArtifacets.sh 脚本时，需要确保 channel-artifacts 目录已经存在，否则可能会报错

chmod 755 generateArtifacts.sh
./generateArtifacts.sh mychannel

将channel-artifacts 和 crypto-config 目录文件拷贝到 47.93.249.250 机器的相同目录

scp -r crypto-config root@47.93.249.250:/opt/gopath/src/github.com/hyperledger/fabric/examples/e2e_cli
scp -r channel-artifacts root@47.93.249.250:/opt/gopath/src/github.com/hyperledger/fabric/examples/e2e_cli

启动docker 进程

docker-compose -f docker-compose-test.yaml up -d

docker 进程启动后，读者可以通过以下命令查看正在运行的进程

docker ps

• 分布式部署（2）

读者此时在 47.93.249.250 机器上切换目录到 /opt/gopath/src/github.com/hyperledger/fabric/examples/e2e_cli，同样的复制一份docker-compose 的配置文件

cp docker-compose-cli.yaml  docker-compose-test.yaml

对 docker-compose-test.yaml 配置进行修改，修改后的内容如下

# Copyright IBM Corp. All Rights Reserved.
#
# SPDX-License-Identifier: Apache-2.0

启动该台机器的docker 相关服务

docker-compose -f docker-compose-test.yaml up -d

docker 进程启动后，读者可以通过以下命令查看正在运行的进程

docker ps

此时屏幕上将输出的类似如下信息

读者可以看到docker中的服务映射的端口号的区别，然后针对不同的docker 服务，继续修改 scripts/script.sh 脚本中的 setGlobals 函数（大约是32行）中，各个docker 服务的端口号

vi scripts/script.sh

setGlobals () {

        if [ $1 -eq 0 -o $1 -eq 1 ] ; then
                CORE_PEER_LOCALMSPID="Org1MSP"
                CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt

                if [ $1 -eq 0 ]; then
                        CORE_PEER_ADDRESS=peer0.org1.example.com:7051
                else
                        CORE_PEER_ADDRESS=peer1.org1.example.com:8051
                fi
        else
                CORE_PEER_LOCALMSPID="Org2MSP"
                CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
                CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
                if [ $1 -eq 2 ]; then
                        CORE_PEER_ADDRESS=peer0.org2.example.com:9051
                else
                        CORE_PEER_ADDRESS=peer1.org2.example.com:10051
                fi
        fi

        env |grep CORE
}

将最新的 scripts/script.sh 脚本上传到docker 的cli 镜像中

注意：c05d72aef89b 是作者docker 的cli 容器编号，具体使用方法可以参考：http://blog.csdn.net/u011596455/article/details/76862271，并且将script.sh 脚本上传cli 容器后，该脚本将一直保存在cli 的容器中（包括重启容器服务）

docker cp scripts/script.sh c05d72aef89b:/opt/gopath/src/github.com/hyperledger/fabric/peer/scripts/

不需要从宿主机器拷贝script.sh 脚本到 cli 中，因为 docker-compose-test.yaml 配置文件中，已经将宿主的script.sh 脚本挂载到cli 中了

    volumes:
        - /var/run/:/host/var/run/
        - ../chaincode/go/:/opt/gopath/src/github.com/hyperledger/fabric/examples/chaincode/go
        - ./crypto-config:/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/
        - ./scripts:/opt/gopath/src/github.com/hyperledger/fabric/peer/scripts/
        - ./channel-artifacts:/opt/gopath/src/github.com/hyperledger/fabric/peer/channel-artifacts

• init fabric 集群环境

 选择其中一台机器进入docker cli 镜像的shell 环境，作者选择了 47.93.249.250 进行操作

docker exec -it cli bash 

再执行script.sh 脚本

./scripts/script.sh mychannel

然后集群就开始真正的初始化，等待所有的操作都结束后，将出现如下信息

到这里，fabric 的集群环境就部署好了，如果读者想部署更多机器的fabric 环境，也可以照葫芦画瓢地进行配置和部署
