Fabric 1.0在Centos 7上面的安装

参考：给了个链接：

http://www.voidcn.com/article/p-szuznezg-bqr.html

首先说明，这里的装法是过时的，网上类似的文章一抓一大把，到最后是肯定装不成功的

会卡在最后一步network-stup.sh up，报错

2018-04-25 03:09:49.100 UTC [grpc] Printf -> DEBU 003 grpc: addrConn.resetTransport failed to create client transport: connection error: desc = "transport: Error while dialing dial tcp: lookup orderer.example.com on 127.0.0.11:53: no such host"; Reconnecting to {orderer.example.com:7050 <nil>}  
Error: Error connecting due to  rpc error: code = Unavailable desc = grpc: the connection is unavailable  

错误如上，咋一看好像是什么host，docker ps -a才发现

是orderer这个容器启动失败了, docker logs e170bd588a44查看：

key的兼容性，shit，整整调试了两天，才搞定

完整安装步骤如下：

一、弄好源

yum install -y wget  
rm -rf /etc/yum.repos.d/*  
wget -q http://mirrors.163.com/.help/CentOS7-Base-163.repo -O /etc/yum.repos.d/CentOS7-Base-163.repo  

二、校准时间

yum install -y ntp ntpdate ntp-doc  
ntpdate 0.us.pool.ntp.org  
hwclock --systohc  
systemctl enable ntpd.service  
systemctl start ntpd.service  

三、升级核心，安装开发包

rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-3.el7.elrepo.noarch.rpm  
yum install lsof deltarpm -y  
yum -y --enablerepo=elrepo-kernel install kernel-ml # will install 3.11.latest,stable, mainline

yum groupinstall -y "development tools"  
grub2-mkconfig -o /boot/grub2/grub.cfg  
grub2-set-default 0  
reboot  

以上三步其实也可以省略，嘿嘿，掉坑了吧

四、装Docker和docker-compose

yum install -y docker  
systemctl enable docker  
systemctl start docker  
curl -L https://get.daocloud.io/docker/compose/releases/download/1.16.1/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose  
chmod +x /usr/local/bin/docker-compose  

五、安装go，1.7.5的版本，因为我看了Fabric的ci，是用的1.7.5，我们就对准好了

wget https://storage.googleapis.com/golang/go1.7.5.linux-amd64.tar.gz  
tar xf go1.7.5.linux-amd64.tar.gz  
mv go /usr/local/  
mkdir -p /root/golang  
cat<<EOF>>/etc/profile  
export GOPATH=/root/golang  
export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin  
EOF  
ln -s /root/golang /opt/gopath  
source /etc/profile  

六、clone Fabric

yum install git -y  
yum update nss curl  
git clone -b release-1.0 https://github.com/hyperledger/fabric  

网上的错误都在于此，都是去clone了master分支的，然后checkout -b v1.0.0，这样是不对的，必须去clone这个独立的release-1.0分支。 升级nss和curl的原因是我的Centos 7是CentOS Linux release 7.1.1503 (Core)，够古老，不升级git会报错。

七、下载docker镜像

cd /root/golang/src/github.com/hyperledger/fabric/examples/e2e_cli  
source download-dockerimages.sh -c x86_64-1.0.6 -f x86_64-1.0.6  

注意这里，实际release-1.0的版本号是1.0.6，所以下1.0.6的，最好用代理下，或者什么阿里或者daocloud的加速器下，方法如下：

启用docker官方中国区加速器：
vim /etc/sysconfig/docker  
OPTIONS='--selinux-enabled --log-driver=journald --signature-verification=false  --registry-mirror=https://registry.docker-cn.com'  
systemctl restart docker  

八、搞定

cd /root/golang/src/github.com/hyperledger/fabric/examples/e2e_cli

./network_setup.sh up
