节点1/键值存储：192.168.50.130

节点2：192.168.50.131

1.下载Consul二进制包并启动

wget https://releases.hashicorp.com/consul/0.9.2/consul_0.9.2_linux_amd64.zip

unzip consul_0.9.2_linux_amd64.zipmv consul /usr/bin/consul && chmod +x /usr/bin/consul

nohup consul agent -server -bootstrap -ui -data-dir /var/lib/consul -client=192.168.50.130 -bind=192.168.50.130

&>/var/log/consul.log &

2.节点配置Docker守护进程连接Consul

vi /lib/systemd/system/docker.service

[Service]

ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock --cluster-store

consul://192.168.50.130:8500 --cluster-advertise 192.168.1.130:2375

systemctl restart docker

3.创建overlay网络

docker network create -d overlay multi_host

4.测试互通

docker run -itd --net=multi_host busybox

节点B：192.168.50.131

1.启动docker：

Systemctl start docker

2.修改配置文件：vim /usr/lib/systemd/system/docker.service

-H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock --cluster-store consul:// 192.168.50.131:8500 --cluster-advertise 192.168.50.131:2375

systemctl daemon-reload && systemctl restart docker

就可以在consul ui上面看到新增加的节点了

3.创建overlay网络：

docker network create -d overlay multi_host（只要在一个节点创建，就会同步到其他节点，不需要在配置其他节点）

4.测试互通：

　　A B节点都启动一个容器

　　docker run -it --rm=true  --net=multi_host mydockerfile /bin/bash

ping overlay分配的网络
