因为要搭建fabric1.4的，orderer节点，kafka共识，zookeeper注册，出现问题考虑几个原因

1.防火墙问题

service iptable? status

service firewalld status

若开启直接关闭

2.host问题

若是多机器物理环境，记得配置host

根据设置的docker网络模式修改

docker网络模式为host，直接物理机修改? vi?? /etc/hosts

docker桥接网络，新增docker容器配置?

docker run -d --name test1 \ --add-host test1.a:1.2.3.4 \ local/test

docker-compose配置

test2: build: local/test extra_hosts: test1.a: 1.2.3.4 test1.b: 4.3.2.1

比如这里采用的新增docker-compose配置

3.本机服务0.0.0.0绑定问题

本示例三台物理机zookeeper，每个本机的服务地址都修改为0.0.0.0即可，网络环境复杂，写成域名可能会导致接收不到消息，zookeeper1的配置对应修改为0.0.0.0，2的把域名修改为0.0.0.0，3的修改3的域名为0.0.0.0
