fabric 启动过程常见问题

错误信息

Error response from daemon: Cannot start container web: iptables failed: iptables -t nat -A DOCKER -p tcp -d 0/0 –dport 32797 -j DNAT –to-destination 172.17.0.30:5000 ! -i docker0: iptables: No chain/target/match by that name.

解决办法：重建docker0网络恢复

依次执行下面的命令：

pkill docker 
iptables -t nat -F 
ifconfig docker0 down 
brctl delbr docker0 
docker -d 
service docker restart

执行

./peer.sh chaincode package demo-pack.out -n demo -v 0.0.1 -s -S -p github.com/introclass/hyperledger-fabric-chaincodes/demo

错误信息

解决npm ERR! 过程出现 Unexpected end of JSON input while parsing near

1. 删掉package.lock.json
2. 清除cache

npm cache clean --force

3. 还原官方镜像

npm set registry https://registry.npmjs.org/

Handshake failed with fatal error SSL_ERROR_SSL

ssl证书错误，找到对应证书或不适用加密连接

服务启动时好时坏,环境清理之后解决

docker rm -f $(docker ps -aq)
docker rmi -f $(docker images | grep fabcar | awk ‘{print $3}’)
rm -rf channel-artifacts crypto-config
mkdir channel-artifacts crypto-config
docker volume prune
docker network rm net_byfn
./byfn.sh generate

./byfn.sh restart

端口bind失败

lsof -i:7050
然后kill

初始化合约失败

调用 peer chaincode instantiate响应错误：

Error: could not assemble transaction, err proposal response was not successful, error code 500, msg chaincode registration failed: container exited with 1

原因是使用java编写的链码，不能出现中文字符。
在初始化合约时，fabric会启动一个hyperledger/fabric-javaenv 的容器对合约进行下载依赖包及编译。编译过程可以查看日志，而编译结束，无论成功失败，容器都会被删掉。
