區塊鏈學習之Fabric安裝與運行（虛擬機下CentOS7）

前期配置：

更新源和yum庫：

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

yum clean all

yum makecache

yum updata

（若本地安裝，則按之後Go安裝包流程來，推薦在線安裝）

Docker在線安裝：

yum install -y yum-utils \device-mapper-persistent-data \lvm2

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

yum-config-manager --enable docker-ce-edge

yum-config-manager --enable docker-ce-test

yum install docker-ce

這一句會有點久，但當安裝完成時，即意味着docker安裝完成。可通過docker version查看。

注意，如果docker version不行

輸入命令行：

service docker restart

可能出現問題：

[root@woai33 jack]# service docker restart

Redirecting to /bin/systemctl restart docker.service
Job for docker.service failed because start of the service was attempted too often. See "systemctl status docker.service" and "journalctl -xe" for details.
To force a start use "systemctl reset-failed docker.service" followed by "systemctl start docker.service" again.

輸入systemctl status docker.service查看結果：

按這裏https://blog.csdn.net/zhangbeizhen18/article/details/85239758試了一遍並不行，但最後發現解決辦法：去編輯 /etc/docker/daemon.json，這裏的文件錯誤會導致此類錯誤，一般將內容修改爲：

{ 
        "registry-mirrors":["https://registry.docker-cn.com"] 
}

 

在線安裝Docker-compose：

參考教程：https://docs.docker.com/compose/install/

sudo curl -L "https://github.com/docker/compose/releases/download/1.25.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

如果輸入：docker-compose version 不行，繼續輸入：用於將文件移入/usr/bin/中

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

 

本地安裝Go：

解壓本地已下載好的go壓縮包到/usr/local/software/中

tar -C /usr/local/software -xzf go-xxx.tar.gz

 編輯配置文件並更新路徑

   vim /etc/profie

 在最後添加以下兩句：   

export PATH=$PAHT:/usr/local/software/go/bin

export GOPATH=/opt/gopath

再esc  i  :wq 退出後輸入：

source /etc/profile 

更新配置 ，最後輸入 go version 有顯示即可

擴：ftp文件傳輸

ftp：用戶名：主機名；密碼：登錄密碼

打開控制面板—>軟件—>功能—>Internet

 

Fabric安裝：

項目路徑：https://github.com/hyperledger/fabric

安裝git：

yum install git

新建文件夾：

mkdir -p /opt/gopath/src/github.com/hyperledger

進入此文件夾：

cd /opt/gopath/src/github.com/hyperledger

再通過git clone https://github.com/hyperledger/fabric 即可將fabric下載到目前所在目錄下，之後通過進入並執行

scripts/bootstrap.sh

即可下載鏡像

若需要相關鏡像，可在docker官網上搜索下載：

例：https://hub.docker.com/r/hyperledger/fabric-kafka/tags 即可得到下載鏈接：

docker pull hyperledger/fabric-kafka:latest

並可通過docker images 查看

 

實例一：Building Your First Network —— 第一個網絡

官方教程：https://hyperledger-fabric.readthedocs.io/en/release-1.4/build_network.html

中文版：https://blog.csdn.net/hugowang/article/details/83113964

注意，第一步，先執行bootstrap.sh，否則，會報錯：cryptogen tool not found.exiting

當出現問題時，如果執行後無效，可以試着直接將該文件下載下載進行解壓，而不是按教程來https://blog.csdn.net/mellymengyan/article/details/77671185

通過下載需要的包：

https://github.com/hyperledger/fabric/releases/download/v1.4.4/hyperledger-fabric-linux-amd64-1.4.4.tar.gz

並將下載的hyperledger-fabric-linux-amd64-1.4.4.tar.gz下載後解壓到

/opt/gopath/src/github.com/hyperledger/fabric/scripts/fabric-samples/

中。當fabric-samples中有了bin文件夾和first-network時，即可進入first-network開始執行

./byfn.sh generate

開始創建網絡。

正常配置如圖：

開始創建：

最後：通過命令行：

./byfn.sh up

即可完成網絡的構建
