fabric从1.0.0起就支持多通道技术，关于多通道的解释，本文不多赘述，可以自行google。
本文以 example的e2e_cli 为基础，在此上进行修改
需要注意的是，我在e2e_cli的基础上做了一定修改来启动fabric，如果照搬一下脚本，是运行不起来的，以下仅供参考
说明一下思路：
1、一条链对应：至少一个org，至少一个peer，至少一个chaincode
2、在一条链对应的基础上，对script.sh脚本进行修改
步骤：
1、已经执行 ./network_setup.sh up
2、修改 e2e_cli下 generateArtifacts.sh 为 generateNewChannel.sh（见下文）
3、修改 e2e_cli下script文件夹内的script.sh 为 script_new_channel.sh（见下文）
4、先在虚拟机上直接运行 ./generateNewChannel.sh [新通道名]
后进入cli容器执行 ./script/script_new_channel.sh [新通道名] [新智能合约名]
generateNewChannel.sh
