在前面我们已经介绍了什么是Consul，接下来，我们将介绍下怎么搭建一个集群。 环境准备 节点名称 ip 角色 ams1 192.168.42.33 leader ams2 192.168.42.198 server ams3 192.168.42.85 server ams4 192.168.42.252 client

$ wget https://releases.hashicorp.com/consul/1.0.2/consul_1.0.2_linux_amd64.zip
$ unzip onsul_1.0.2_linux_amd64.zip -d /usr/bin
$ consul version
Consul v1.0.2
Protocol 2 spoken by default, understands 2 to 3 ( agent will automatically use protocol >2 when speaking to compatible agents)
Consul安装之后，运行Agent。
Agent可以在server或client模式下运行。每个数据中心都必须至少有一个运行于serve，但推荐使用3台或5台服务器。
