1.docker启动consul

下载安装docker以后运行如下代码:

docker run -d  -p 8500:8500/tcp --name consul  consul agent -server -ui -bootstrap-expect=1 -client=0.0.0.0

如果启动无效,关闭你的防火墙或者开放端口.

2.和SpringBoot集成

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-consul-discovery</artifactId>
        </dependency>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Edgware.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

把maven地址和依赖管理加入到SpringBoot中pom文件中

在yum文件cloud下添加如下代码

spring.cloud.consul.host=你的consul地址
spring.cloud.consul.prot=你的端口号
spring.cloud.consul.discovery.prefer-ip-address=true
spring.cloud.consul.discovery.heartbeat.enabled=true
spring.cloud.consul.discovery.health-check-path=health (必须写这个)

在你的启动类上添加发现注解

@EnableDiscoveryClient
