   https://www.evoila.de/2016/03/08/consul-nginx-a-complete-installation-guide/?lang=en

###1、安装consul0.6.3,此步骤安装后，consul命令可以执行查询 consul version 版本
1、apt-get install unzip
2、wget https://releases.hashicorp.com/consul/0.6.3/consul_0.6.3_linux_amd64.zip
3、unzip consul_0.6.3_linux_amd64.zip
4、mv consul /bin
5、rm consul_0.6.3_linux_amd64.zip
###2、安装consul的web UI,consul UI 可以查看主要服务发现状态。
1、mkdir /opt/consul-ui
2、cd /opt/consul-ui
3、wget https://releases.hashicorp.com/consul/0.6.3/consul_0.6.3_web_ui.zip
4、unzip consul_0.6.3_web_ui.zip
5、rm consul_0.6.3_web_ui.zip
###3、consul 集群server配置，其中/tmp/consul为启动后生成的运行文件，如下start_join为集群IP地址池

mkdir /etc/consul    
cat << EOF > /etc/consul/config.json
{                                             
  "datacenter": "test-dc",                                           
  "data_dir": "/tmp/consul",
  "log_level": "DEBUG",                                             
  "node_name": "consul00",
  "server": true,                                               
  "bootstrap_expect": 3,                                               
  "ui_dir": "/opt/consul-ui",                                        
  "bind_addr": "192.168.0.101",                                          
  "leave_on_terminate": true,
  "start_join": [                                                   
    "192.168.0.101",                                                   
    "192.168.0.102",                                                    
    "192.168.0.103"
  ]                                               
}
EOF

###4、consul 集群client配置

mkdir /etc/consul
cat << EOF > /etc/consul/config.json
{
  "datacenter": "test-dc",
  "data_dir": "/tmp/consul",
  "log_level": "DEBUG",
  "server": false,
  "leave_on_terminate": true,
  "start_join": [
    "192.168.0.101",                                                   
    "192.168.0.102",                                                    
    "192.168.0.103"
 ]
}
EOF

###5、consul 加入server服务，下图内容中加入到/etc/init.d/consul文件中， consul配置内容

添加完文件后执行权限操作

chmod +x /etc/init.d/consul
sudo update-rc.d consul defaults

###6、启动consul service consul start

###7、consul客户端连consul命令 consul agent -data-dir /tmp/consul -ui -join 192.168.0.101 -bind=192.168.1.127 -dc=test-dc

###8、consul操作命令 1、查看状态 consul members 2、离开 consul leave
