启动Fabric

现在所有文件都已经准备完毕，我们可以启动我们的Fabric网络了。

启动orderer

让我们首先来启动orderer节点，在orderer服务器上运行：

docker-compose -f docker-compose-cli.yaml up

运行完毕后我们可以使用docker ps看到运行了一个名字为orderer.example.com的节点。

[root@iz2zeivrkckulq2dtidztmz e2e_cli]# docker-compose -f docker-compose-cli.yaml up

解决方法

1）第一种：这里我们将Python的默认编码方式修改为utf-8，就可以规避上述问题的发生，具体方式，我们在Python文件的前面加上如下代码：

import sys
defaultencoding = 'utf-8'
if sys.getdefaultencoding() != defaultencoding:
    reload(sys)
    sys.setdefaultencoding(defaultencoding)
 2）第二种：我们在/usr/lib/python2.7/site-packages/目录下添加一个sitecustomize.py文件，内容如下：

import sys
sys.setdefaultencoding('utf-8')
 这种方式可以解决所有项目的encoding问题，具体说明可参考/usr/lib/python2.7/site.py文件：

docker-compose -f docker-compose-cli.yaml down

执行命令

docker run -it cli bash

异常：

[root@iz2zeivrkckulq2dtidztmz e2e_cli]# docker exec -it cli bash
Error response from daemon: Container 1f9b6f7d709f263f4a67a67ad91b419b13844efaaa4caeb6dd571bfa829822c7 is not running

解决方法：

cli:
    container_name: cli
...
   working_dir: /opt/gopath/src/github.com/hyperledger/fabric/peer
   # command: /bin/bash -c './scripts/script.sh ${CHANNEL_NAME} ${DELAY}; sleep $TIMEOUT'
    volumes:
        - /var/run/:/host/var/run/
...

注释

command: /bin/bash -c './scripts/script.sh ${CHANNEL_NAME} ${DELAY}; sleep $TIMEOUT'

进入cli执行

./scripts/script.sh mychannel

查询

peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

转帐

peer chaincode invoke -o orderer.example.com:7050  --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem  -C mychannel -n mycc -c '{"Args":["invoke","a","b","20"]}'
