使用~/go/bin/confitxgen 工具来生成交易配置：
# 创建一个配置目录
mkdir config
export FABRIC_CFG_PATH=$PWD
export CHANNEL_NAME=mychannel
# 生成创世区块
configtxgen -profile OneOrgOrdererGenesis -outputBlock ./config/genesis.block
# 生成创建通道的配置文件
configtxgen -profile OneOrgChannel -outputCreateChannelTx ./config/channel.tx -channelID $CHANNEL_NAME
# 创建锚节点配置文件
configtxgen -profile OneOrgChannel -outputAnchorPeersUpdate ./config/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP
成功执行完以上命令后会在~/my-basic-network/config目录下生成以下三个文件:
channel.tx genesis.block Org1MSPanchors.tx

我们可以看到上面创建通道和将peer加入通道的输出中， 我们在源码里面的改动生效了， 通过这样的方式可以改动fabric源码后不用频繁编译超级账本镜像文件了。
如果我们要改动源码，流程是首先在主机上改动代码，然后到compile容器中编译代码， 然后在其他容器中执行编译后的程序，由于这几个容器都能看到主机上~/go/bin目录中的内容，只要compile容器中代码编译完成后，其他容器中立马就能使用它
原因：
ocker进程使用Unix Socket而不是TCP端口。而默认情况下，Unix socket属于root用户，需要root权限才能访问
解决办法：
#添加docker用户组
sudo groupadd docker
#将登陆用户加入到docker用户组中
sudo gpasswd -a $USER docker
#更新用户组
newgrp docker
#测试docker命令是否可以使用sudo正常使
docker ps
