查看一下orderer的日志，看清楚它到底是具体的哪一个部分有问题，看到大多数的问题在于：

错误原因
没有删除干净的环境中启动复用的之前的volume
解决方案
执行如下三条命令删除卷
docker-compose -f docker-compose-cli.yaml down --volumes --remove-orphans
docker rm -f $(docker ps -a | grep "hyperledger/*" | awk "{print $1}")
docker volume prune
【node】- npm install时报错：npm WARN enoent ENOENT: no such file or directory
解决方法：
在cmd命令行中输入：
npm config set registry https://registry.npm.taobao.org
npm config set disturl https://npm.taobao.org/dist
再输入npm install -g koa -g表示安装在全局
npm安装模块的 npm WARN root@1.0.0 No description 和 npm WARN root@1.0.0 No repository filed 的解决方法
报错分析
是因为系统在给你配置package.json文件的时候并没有帮你设置description字段和存储库字段，需要我们自己手动设置。直接用vim打开这个文件编辑：
解决方法
如图设置：description字段的内容无所谓，不为空即可；第二个权限设置成私有的即可。接下来就可以正常使用npm安装命令了。
Error: got unexpected status: BAD_REQUEST
@Error: got unexpected status: BAD_REQUEST – error applying config update to existing channel ‘mychannel’
原因分析
此问题是历史数据未清除干净，可能造成的原因：由于在本机尝试过fabric的e2e_cli，fabric-samples的first-network启动部署测试，多个启动时未正常关闭，根源是由于有一个已经存在的channel，阻止进一步的执行而引起的
解决办法
./byfn.sh -m restart -c mychannel
Error: error getting endorser client for channel: endorser client failed to connect to peer0
解决办法
sudo vim /etc/resolv.conf 首先修改文件最后一行为 #options edns0
:wq! 保存退出
再./byfn.sh -m up -c jschannel 即可启动
