   ## Install Consul
   1. download consul

   ```
   
   2. unzip to `/usr/bin` 
   
   ```
   $ sudo unzip consul_1.7.3_linux_amd64.zip -d /usr/bin
   ```
   
   3. create consul service file
   ```
   $ sudo vim /lib/systemd/system/consul.service
   
   [Unit]
   Description=consul
   [Service]
   ExecStart=/usr/bin/consul agent -config-dir /etc/consul
   KillSignal=SIGINT
   ```
   
   4. create server json file
   ```sh
   $ sudo mkdir /etc/consul/
   
   $ sudo vim /etc/consul/server.json
   ```
   
   ```json
   {
   	"data_dir": "/var/consul",
   	"log_level": "INFO",
   	"node_name": "test",
   	"server": true,
   	"ui": true,
   	"bootstrap_expect": 1,
   	"client_addr": "0.0.0.0",
   	"advertise_addr": "127.0.0.1",
   	"ports": {
   		"dns": 53
   	},	
   	"advertise_addr_wan": "127.0.0.1"
   }
   ```
   
   5. start consul
   ```sh
   $ sudo systemctl start consul
   ```
   
   ## start service - golang version
   
   ```sh
   $ git clone https://github.com/api7/consul-test-golang.git
   
   $ cd consul-test-golang
   
   $ nohup go run main.go &
   ```
   
   
   ## install etcd  -- need by Apache APISIX
   ```sh
   $ sudo yum install etcd
   
   $ nohup /usr/bin/etcd --enable-v2=true &
   ```
   
   ## install openresty -- need by Apache APISIX
   
   ```sh
   $ wget https://openresty.org/package/centos/openresty.repo
   
   $ sudo mv openresty.repo /etc/yum.repos.d/
   
   $ sudo yum install openresty -y
   ```
   
   ## install Apache APISIX
   
   1. install from RPM, and you can get the latest version from https://github.com/apache/incubator-apisix/releases
   
   ```sh
   $ wget https://github.com/apache/incubator-apisix/releases/download/1.3/apisix-1.3-0.el7.noarch.rpm
   
   $ sudo yum install apisix-1.3-0.el7.noarch.rpm -y
   ```
   
   2. change config.yaml
   
   ```sh
   $ vi /usr/local/apisix/conf/config.yaml
   
   $ add consul address to `dns_resolver`：
   ```
   
   ```yml
     dns_resolver:
      - 127.0.0.1
   ```
   
   3. start Apache APISIX:
   ```
   $ sudo apisix start
   ```
   
   ## Test
   
   1. add route in Apache APISIX:
   ```
   $ curl http://127.0.0.1:9080/apisix/admin/routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -i -d '
   {
       "uri": "/healthz",
       "upstream": {
           "type": "roundrobin",
           "nodes": {
               "go-consul-test.service.consul:8080": 1
           }
       }
   }'
   
   ```
   
   **go-consul-test.service.consul is registered DNS SRV by consul-test-golang service**
   
   
   2. test：
   ```sh
   $ curl http://127.0.0.1:9080/healthz
   ```
   will return:
   ```json
   {"message":"consul test healthz"}
   ```
   
   Cool, it works!
