构建fabric单机多节点⽹络

在进⾏后续操作之前将 fabric-samples/bin ⽬录添加到 PATH 变量中，这样就可以在任意位置

使⽤fabric提供的⼆进制⽂件命令

echo "export PATH=$PATH:$HOME/Documents/fabric-learn/fabric-samples/bin" >>

~/.bash_profile

⼯作⽬录为 fabric-samples/setup-up-my-network

1.⽣成加密材料

这⼀步通过 cryptogen ⼯具完成

output="organizations"

cryptogen generate --config=./organizations/cryptogen/crypto-config-org2.yaml --

output="organizations"

cryptogen generate --config=./organizations/cryptogen/crypto-config-orderer.yaml --

output="organizations"

2.创建系统channel的创世块

这⼀步⽤到了 configtxgen 命令，可通过 --help 参数查看该命令帮助信息。

该命令需要⼀个配置⽂件 configtx.yaml 才能执⾏(⽂件名固定)，可以从 test-network/configtx

⽬录下拷⻉

下⾯是修改之后的 configtx.yaml 配置⽂件

allow modification of non-application parameters during channel create tx generation.

Only valid in conjunction with 'outputCreateChannelTx'.

-channelID string

The channel ID to use in the configtx

-configPath string

The path containing the configuration to use (if set)

-inspectBlock string

Prints the configuration contained in the block at the specified path

-inspectChannelCreateTx string

Prints the configuration contained in the transaction at the specified path

The path to write a channel creation configtx to (if set)

-printOrg string

Prints the definition of an organization as JSON. (useful for adding an org to a

channel manually)

-profile string

The profile from configtx.yaml to use for generation.

-version
