docker拉取最新的consul镜像：docker pull consul

创建数据中心1：docker run -d -p 8501:8500 --restart=always -v /e/docker/consul/data/server1:/consul/data -v /e/docker/consul/conf/server1:/consul/config -e CONSUL_BIND_INTERFACE='eth0' --privileged=true --name=consul_server_1 consul agent -server -bootstrap-expect=3 -ui -node=node_consul_server_1 -client='0.0.0.0' -data-dir /consul/data -config-dir /consul/config -datacenter=dc1

linux:docker run -d -p 8501:8500 --restart=always -v /home/mysite/docker/consul/data/server1:/consul/data -v /home/mysite/docker/consul/conf/server1:/consul/config -e CONSUL_BIND_INTERFACE='eth0' --privileged=true --name=consul_server_1 consul agent -server -bootstrap-expect=3 -ui -node=consul_server_1 -client='0.0.0.0' -data-dir /consul/data -config-dir /consul/config -datacenter=tengxun

通过执行 docker inspect -f '{{.NetworkSettings.IPAddress}}' consul_server_1 获取server1的IP

创建server2和3并加入节点：

docker run -d -p 8502:8500 --restart=always -v /e/docker/consul/data/server2:/consul/data -v /e/docker/consul/conf/server2:/consul/config -e CONSUL_BIND_INTERFACE='eth0' --privileged=true --name=consul_server_2 consul agent -server -ui -node=consul_server_2 -client='0.0.0.0' -data-dir /consul/data -config-dir /consul/config -datacenter=dc1 -join 172.17.0.2

docker run -d -p 8503:8500 --restart=always -v /e/docker/consul/data/server3:/consul/data -v /e/docker/consul/conf/server3:/consul/config -e CONSUL_BIND_INTERFACE='eth0' --privileged=true --name=consul_server_3 consul agent -server -ui -node=consul_server_3 -client='0.0.0.0' -data-dir /consul/data -config-dir /consul/config -datacenter=dc1 -join 172.17.0.2

linux:docker run -d -p 8503:8500 --restart=always -v /home/mysite/docker/consul/data/server2:/consul/data -v /home/mysite/docker/consul/conf/server2:/consul/config -e CONSUL_BIND_INTERFACE='eth0' --privileged=true --name=consul_server_2 consul agent -server -ui -node=consul_server_2 -client='0.0.0.0' -data-dir /consul/data -config-dir /consul/config -datacenter=tengxun -join 172.17.0.8

docker run -d -p 8502:8500 --restart=always -v /home/mysite/docker/consul/data/server3:/consul/data -v /home/mysite/docker/consul/conf/server3:/consul/config -e CONSUL_BIND_INTERFACE='eth0' --privileged=true --name=consul_server_3 consul agent -server -ui -node=consul_server_3 -client='0.0.0.0' -data-dir /consul/data -config-dir /consul/config -datacenter=tengxun -join 172.17.0.8

-bootstarp-expect 3 3个才会启动集群，少于的话启动失败（所以在成功创建第三个server前，查看ui是失败的）

执行：docker exec consul_server_1 consul operator raft list-peers 查看consul状态

---

创建client1:docker run -d -p 8504:8500 --restart=always -v /e/docker/consul/conf/client1:/consul/config -e CONSUL_BIND_INTERFACE='eth0' --name=consul_client_1 consul agent -node=consul_client_1 -client='0.0.0.0' -config-dir /consul/config -datacenter=dc1 -join 172.17.0.2

创建:client2: docker run -d -p 8505:8500 --restart=always -v /e/docker/consul/conf/client2:/consul/config -e CONSUL_BIND_INTERFACE='eth0' --name=consul_client_2 consul agent -node=consul_client_2 -client='0.0.0.0' -config-dir /consul/config -datacenter=dc1 -join 172.17.0.2

docker run -d -p 8504:8500 --restart=always -v /home/mysite/docker/consul/conf/client1:/consul/config -e CONSUL_BIND_INTERFACE='eth0' --name=consul_client_1 consul agent -node=consul_client_1 -client='0.0.0.0' -config-dir /consul/config -datacenter=tengxun -join 172.17.0.8

docker run -d -p 8505:8500 --restart=always -v /home/mysite/docker/consul/conf/client2:/consul/config -e CONSUL_BIND_INTERFACE='eth0' --name=consul_client_2 consul agent -node=consul_client_2 -client='0.0.0.0' -config-dir /consul/config -datacenter=tengxun -join 172.17.0.8

创建数据中心2：docker run -d --name=consul2-1 -e CONSUL_BIND_INTERFACE='eth0' consul agent -server -bootstrap-expect 2 -datacenter='datacenter2'

查询数据中心1的容器IP：docker inspect --format '{{ .NetworkSettings.IPAddress }}' consul1-1

将数据中心2关联到数据中心1上： docker exec -it consul2-1 consul join -wan 172.17.0.3(好像不是这样子的)

将节点添加数据中心2：docker run -d --name=consul2-2 -e CONSUL_BIND_INTERFACE=eth0 consul agent --datacenter=datacenter2 --server=true --client=0.0.0.0 --join 172.17.0.4

重点：

linux服务器上部署了一个consul server,然后其中docker中部署了3个server和2个client，但是server无法加入到集群中，client可以。搞了半天，最后发现两个consul的版本不一样，最后将 docker中的镜像更新到1.8.3和服务器上一致，问题解决。起始在docker的日志中可以看到提示版本的问题
