手动创建通道失败

来源：6-3 网络搭建完结篇

TeaR_0502

2020-01-11

我在生成的时候都挺顺利的。
docker compose 启动也都正常

peer channel list 响应结果也是预期的（可以连上节点，看到连接的通道是空的）

但是我在创建通道的时候发生了异常

具体指令为
peer channel create -o orderer.t4cloud.com:7050 -c t4channel -f /etc/hyperledger/config/t4cloud.tx

其中的orderer.t4cloud.com,容器启动正常，我之前看过docker启动log，确实是等待服务的日志（视频中说这样就是启动成功了）
通道名称t4channel这个也是正常的，我尝试过使用别的，就会提示通道ID不一致。
最后的交易文件读取正常，如果修改成别的，也会提示文件无法读取

令我困惑的是他的异常提示，是空的，导致百度无法下手，看过好一些，无法解决，只能向老师求助一下。

这是我的docker容器运行状态，看起来版本号都是1.0.0应该也没错

图片描述

希望老师能帮忙排查一下问题，谢谢

–以下是补充的order日志

图片描述

我搜索过这个显眼的红色部分的异常（看上去好像是配置错误，但是我确实按照老师的文件配置的）。
有一个问题说是order节点的配置不对，正确的应该是GENESISMETHOD=file，我看了docker-compose中的order配置，也确实是这样的。其他能搜索到的结果都和这个不一样。

然后我注意到了蓝色部分，也去搜索了一下，同样只有疑问没有解决办法。

于是只好又来求助了- -

一下是我使用的configtx配置

生成证书
./cryptogen generate --config=./crypto-config.yaml

创建创世区块及交易
./configtxgen -profile OneOrgOrdererGenesis -outputBlock ./config/genesis.block -channelID t4channel
./configtxgen -profile TwoOrgChannel -outputCreateChannelTx ./config/t4cloud.tx -channelID t4channel

创建通道
peer channel create -o orderer.t4cloud.com:7050 -c t4channel -f /etc/hyperledger/config/t4cloud.tx

后续异常补充

在我使用小写的不同的名字的时候，出现了go语言的异常，看起来好像是没有响应信息。
（这个我搜了下说是GO语言的环境有问题，可是当前实在官方的docker镜像中……）
网上说可能是容器环境有问题，我

然后看order节点的日志，好像是没问题，都成功了

图片描述

在这种情况下，我尝试过无视异常，然后加入链，会提示tx文件不存在。
如果再次生成链，会生成失败，提示version为1，我搜了下，好像是代表链已存在。

【最终问题解决，成功创建通道】

注意点
1.创世区块和交易链的通道ID不能一样
2.通道名称，不能有大写，（因为我写JAVA习惯了驼峰），但是在此处会有一场，order节点日志：通道ID有非法自读
3.cli客户端的环境变量中缺少 - GODEBUG=netdns=go 导致响应异常。

谢谢老师大半夜的帮我找错误。

已采纳

这个时候可以看orderer的日志，应该会有错误的提示

cli节点上创建通道等操作实际上是通过向Order节点发送命令在Order节点创建通道的么？

application启动前，启动集群就行了吗？是否需要手动的创建通道，加入通道之类的？
