1、vagrant

為了模擬集群效果，使用vagrant。

1.1、首先下載vagrant

https://www.vagrantup.com/downloads.html

說明：瀏覽器下載可能比較慢，可以通過迅雷下載。

1.2、下載之后，安裝vagrant

mac中下一步到底就可以。

說明：雖然vagrant需要依賴於virtualbox，需要事先安裝。

1.3、打開終端，啟動vagrant

1.3.1、初始化：

說明：以上是安裝64bit的Linux系統（Ubuntu）,32bit的將數字改為32即可。

1.3.2、修改Vagrantfile文件

說明：ruby寫的，內容改為如下：

 1 # -*- mode: ruby -*-
 2 # vi: set ft=ruby :
 3 $script = <<SCRIPT
 4 echo Installing dependencies...
 5 sudo apt-get update
 6 sudo apt-get install -y unzip curl
 7 echo Fetching Consul...
 8 cd /tmp/
 9 wget https://releases.hashicorp.com/consul/0.6.1/consul_0.6.1_linux_amd64.zip -O consul.zip
10 echo Installing Consul...
11 unzip consul.zip
12 sudo chmod +x consul
13 sudo mv consul /usr/bin/consul
14 sudo mkdir /etc/consul.d
15 sudo chmod a+w /etc/consul.d
16 SCRIPT

18 # Vagrantfile API/syntax version. Don't touch unless you know what you're doing!

21 Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
22   config.vm.box = "debian/wheezy64"
23 
24   config.vm.provision "shell", inline: $script

27       n1.vm.hostname = "n1"
28       n1.vm.network "private_network", ip: "172.20.20.10"
29   end
30 
31   config.vm.define "n2" do |n2|
32       n2.vm.hostname = "n2"
33       n2.vm.network "private_network", ip: "172.20.20.11"
34   end
35 end

該文件內容是consul官方推薦的demo。這一塊兒內容可以根據實際情況去修改。（我將節點的IP自己指定了一下，盡量不要與自己本機的IP一樣，否則可能會影響一些功能），以下是我的配置。
