**** consul agent -dev 模式下  搭建了 几个微服务，注册到consul （V1.4.3）上 现在几个微服务重启后，在consul的健康页面上查看几个微服务状态很奇怪 使用zuul进行转发访问都是找不到service-id 通过请求 http://localhost:19003/actuator/health 查看，服务状态都是down的，想问下是怎么回事？  注：第一次从头再来，都是正常up的，只要一重启某个服务，就某个服务异常了。 下面为配置： ## admin-service  ## gateway-service  请求：localhost:19002/admin/getTest ****

spring cloud spring boot 中使用zuul+consul, zuul路由不到配置了context-path的客户端，不配置context-path可以路由。 网关配置：  被调用服务配置：  网关调用报错：

直接上错误信息：其中svms-file-8585时我的另一个服务id ``` Registering service with consul: NewService{id='svms-file-8585', name='svms-file', tags=[serverType=2, secure=false], address='172.16.128.95', meta=null,

~[spring-cloud-netflix-zuul-2.1.1.RELEASE.jar:2.1.1.RELEASE] ... 64 common frames omitted ```

系统环境： web项目使用单点登录 通过zuul转发到请求到指定的服务端（zuul和服务端不做单点登录） 现在想要把当前登录的用户名传递到后端服务器，但是在zuul上通过过滤器设置 @Override public Object run() { RequestContext ctx = RequestContext.getCurrentContext(); HttpServletRequest request = ctx.getRequest(); request.setAttribute("username", request.getRemoteUser()); logger.info("登陆用户"+request.getRemoteUser()); logger.info("send {} request to {}",request.getMethod(),request.getRequestURL().toString()); return null; } 在zuul的过滤器中能获取到，但是在服务端并不能获取 求教要通过什么办法把参数传递到zuul之后的服务器

在本地启动了1个 Consul。consul agent -dev 添加了配置 ``` spring: application: name: spring-cloud-consul-ok cloud: consul: host: 127.0.0.1 port: 8500 discovery: enabled: true register: true healthCheckInterval: 15s health-check-timeout: 1s instance-id: ${spring.application.name}-${spring.cloud.consul.host}-${spring.cloud.consul.port} serviecName: ${spring.application.name} config: enabled: true format: YAML data-key: configuration ``` 属性配置类： ``` @Configuration @ConfigurationProperties("sample") @Data @RefreshScope public class SampleProperties { private String prop = "default data"; } ``` 引用方式： ``` @SpringBootApplication @EnableDiscoveryClient @EnableHystrix @RestController @EnableConfigurationProperties @EnableFeignClients @Slf4j public class ConsulAreYouOkApplication { @Autowired private RibbonHelloService ribbonHelloService; @Autowired private SampleProperties sampleProperties; @RequestMapping(value = "/hello", method = RequestMethod.GET) public String areyouok(@RequestParam String name) { return ribbonHelloService.sayHi(name)+" "+sampleProperties.getProp(); } ``` 看着没什么错，但是一直 拿不到 Consul上面的配置，从日志里面 也可以看到Spring已经检测到了 属性的变化，但是就是一直获取不到新值。 版本如下 spring-boot-dependencies 1.5.10.RELEASE spring-cloud-consul-config 1.3.2.RELEASE spring-cloud-starter-consul-discovery 1.3.2.RELEASE

请教一个Consul的问题，代码见图，服务注册是可以成功的，不知道为什么解除注册报了连接错误 ConsulClient consulClient = new ConsulClient(nodeHostAdress); Iterator<Map.Entry<String, Service>> it_service = consulClient.getAgentServices().getValue().entrySet().iterator(); java.net.ConnectException: Connection refused (Connection refused) 

直接访问可以，通过zuul网关代理不可以 

ribbon是负载均衡，zuul也可以做到负载均衡，在消费者里面 通过zuul对应url去调服务效果一样吗

最近使用consul作为spring cloud的服务发现，一直不能把服务注册到consul上，发生spring boot使用的是2.1.1.RELEASE版本，后来改成2.0.3.RELEASE能够注册成功。 spring cloud使用Finchley.RELEASE或者Finchley.SR2没有影响。 分别使用consul1.2.1,1.3.1,1.4测试了，结果一样。 哪位同学知道为什么？

如果dev环境consul的配置如下 ``` spring: cloud: consul: host: localhost port: 8500 discovery: hostname: ${spring.cloud.client.ip-address} healthCheckPath: /actuator/health healthCheckInterval: 15s #默认是10s 可设置ps：15s or 1m ip-address: true instanceId: ${spring.application.name}:${spring.cloud.client.ipaddress}:${server.port} tags: ${spring.profiles.active} config: prefix: config enabled: true #默认是true -- format: YAML # 表示consul上面文件的格式 有四种 YAML PROPERTIES KEY-VALUE FILES defaultContext: demo-server # 表示配置文件对应的应用名称 data-key: data #表示consul上面的KEY值(或者说文件的名字) 默认是data profileSeparator: '-' ``` 那么请问在pre环境下。（服务器地址120.78.8.111） cunsul的配置，尤其是host应该怎么配？

在很多博客上看到一些关于consul的介绍以及注册实例，但是几乎没有服务的使用实例， 有介绍说使用Feign进行调用，后面试用轮询的方式，那么如果多个请求同时到达， 轮询的第一个服务会不会压力过大？想了解下关于consul到底是怎样实现负载均衡的，拜托了！

<div class="post-text" itemprop="text"> <p>There are <em>n</em> nodes in a web cluster. Files may be uploaded to any node and then must be distributed to every other node. This distribution does not have to happen in a transaction (in fact it must not, distributed transactions don't scale) and some latency is acceptable, although must be minimal. Conflicts can be resolved arbitrarily (typically last write wins) provided that the resolution is also distributed to all nodes so that eventually all nodes have the same set of files. Nodes can be added and removed dynamically without having to reconfigure existing nodes. There must be no single point of failure and no additional boxes required to solve this (such as RabbitMQ)</p> <p>I am thinking along the lines of using consul.io for dynamic configuration so that each node can refer to consul to determine what other nodes are available and writing a daemon (Golang) that monitors the relevant folders and communicates with other nodes using ZeroMQ. </p> <p>Feels like I would be re-inventing the wheel though. This is a common problem and I expect there are solutions available already that I don't know about? Or perhaps my approach is wrong and there is another way to solve this?</p> </div>

<div class="post-text" itemprop="text"> <p>Does anyone know how to concatenate strings from consul for consul-template? </p> <p>If I have a service 'foo' registered in Consul</p> <pre><code>{ "Node": "node1", "Address": "192.168.0.1", "Port": 3333 }, { "Node": "node2", "Address": "192.168.0.2", "Port": 4444 } </code></pre> <p>I would like consul-template to generate the following line:</p> <pre><code>servers=192.168.0.1:3333,192.168.0.2:4444/bogus </code></pre> <p>The following attempt does not work since it leaves a trailing comma <code>,</code></p> <pre><code>servers={{range service "foo"}}{{.Address}}{{.Port}},{{end}}/bogus # renders servers=192.168.0.1:3333,192.168.0.2:4444,/bogus # What I actually want servers=192.168.0.1:3333,192.168.0.2:4444/bogus </code></pre> <p>I know consul-template uses golang template syntax, but I simply cannot figure out the syntax to get this working. Its likely that I should use consul-template's <code>join</code> but how do I pass both <code>.Address</code> and <code>.Port</code> to <code>join</code>? This is just a trivial example, and I'm not using indexes intentionally since the number of services could be more than two. Any ideas?</p> </div>
