一、部署Consul

1、拉取镜像：

docker pull consul:<consul-version>

2、运行

docker run --name consul1 -p 8300:8300/tcp -p 8301:8301/tcp -p 8301:8301/udp -p 8302:8302/tcp -p 8302:8302/udp -p 8500:8500 -p 8600:8600/tcp -p 8600:8600/udp -v /home/docker/consul/config:/consul/config -itd consul:<consul-version> agent -dev -client 0.0.0.0

3、创建配置文件

创建文件夹

mkdir /home/docker/consul/config -p

创建文件

cd /home/docker/consul/config

创建config.json

vim config.json

填写如下内容：

{
  "datacenter": "dc1",
  "acl": {
    "enabled": true,
    "default_policy": "deny",
    "enable_token_persistence": true,
    "tokens": {
      "master": "master-token",
      "agent": "agent-token"
    }
  },
  "server": true,
  "bootstrap_expect": 1,
  "ui": true
}

4、创建ACL Token

http://<ip>:<port>进入图形界面

进入ACL页面

 创建一个Token，并进入Token详细，点击Use按钮应用这个Token

5、Spring Consul中设置Token

进入对应工程的yml配置文件，在Consul配置中添加如下配置：

spring:
  cloud:
    consul:
      host: ${CONSUL_SERVER_HOST:192.168.193.199}
      port: ${CONSUL_SERVER_PORT:8500}
      acl-token: 00000000-0000-0000-0000-000000000000(你的Token)

二、设置Spring Consul

1、添加Actuator依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

2、添加Actuator配置

spring:
  cloud:
    consul:
      host: ${CONSUL_SERVER_HOST:192.168.193.199}
      port: ${CONSUL_SERVER_PORT:8500}
      acl-token: 00000000-0000-0000-0000-000000000000(你的Token)
      discovery:
        service-name: ${spring.application.name}
        health-check-url: http://${CONSUL_HEALTH_HOST:127.0.0.1}:${UI_CONFIGURATION_SERVICE_PORT:8060}/actuator/health
