首先安装依赖

npm install eureka-js-client

然后新建eureka-client.yml文件

eureka:
  heartbeatInterval: 30000
  registryFetchInterval: 30000
  host: 'localhost'
  port: 8761
  servicePath: '/eureka/apps/'

instance:
  app: 'test-node'
  hostName: 'localhost'
  ipAddr: 'localhost'
  statusPageUrl: 'http://localhost:3000'
  port:
      '$': 3000
      '@enabled': 'true'

  vipAddress: 'razer-node'
  dataCenterInfo:
      '@class': 'com.netflix.appinfo.InstanceInfo$DefaultDataCenterInfo'
      name: 'MyOwn'

然后添加配置

// ------------------ Eureka Config --------------------------------------------
const Eureka = require("eureka-js-client").Eureka;
const client = new Eureka({
    filename: 'eureka-client',
    cwd: __dirname
});
client.logger.level('debug');
client.start(function(error){
    console.log(error || 'complete');
});

这样就完成了node微服务注册到注册中心去了。
