fabric原始碼除錯三：fabric 2.1 去共識

2020-09-20 08:56:03 其他

前言：
（1）網路：一個orderer，兩個組織，每個組織一個peer
（2）將orderer脫離容器啟動；

1、將下面檔案中的ip（192.168.5.83）改成自己的

wang@wang:~/go/src/github.com/hyperledger/fabric/work_dir/test-network/docker$ vim docker-compose-test-net.yaml

2、go module是off狀態（auto也行）（go env -w GO111MODULE=off）

wang@wang:~/go/src/github.com/hyperledger/fabric/work_dir/test-network/docker$ go version
go version go1.14.9 linux/amd64

wang@wang:~/go/src/github.com/hyperledger/fabric/work_dir/test-network/docker$ go env
GO111MODULE="off"

3、清理環境

wang@wang:~/go/src/github.com/hyperledger/fabric/work_dir/test-network$ rm -rf ../orderer/*

wang@wang:~/go/src/github.com/hyperledger/fabric/work_dir/test-network/docker$ ./network.sh down

4、啟動網路

wang@wang:~/go/src/github.com/hyperledger/fabric/work_dir/test-network/docker$ ./network.sh up

日志如下：

wang@wang:~/go/src/github.com/hyperledger/fabric/work_dir/test-network$ ./network.sh up

5、啟動orderer，orderer是脫離容器啟動
