# 链路追踪 #

*  google 的 Dapper
 *  Twitter 的 Zipkin
 *  阿里 的 鹰眼 eagleeye
 *  Sleuth 中集成 Zipkin

## 1. Zipkin server ##

### pom ###

<dependency>
                <groupId>io.zipkin.java</groupId>
                <artifactId>zipkin-server</artifactId>
                <version>2.4.1</version>
            </dependency>
            
            <dependency>
                <groupId>io.zipkin.java</groupId>
                <artifactId>zipkin-autoconfigure-ui</artifactId>
                <version>2.4.1</version>
            </dependency>
    
    原来用：
            <version>2.1.0.RELEASE</version> boot版本比较低
            <version>Greenwich.RELEASE</version> 
    可用的配置：
            <spring-cloud.version>Greenwich.SR2</spring-cloud.version>
            <version>2.1.6.RELEASE</version>
    
            <dependency>
                <groupId>io.zipkin.java</groupId>
                <artifactId>zipkin-server</artifactId>
                <version>2.11.8</version>
                <exclusions>
                    <exclusion>
                        <groupId>org.apache.logging.log4j</groupId>
                        <artifactId>log4j-slf4j-impl</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>
            <dependency>
                <groupId>io.zipkin.java</groupId>
                <artifactId>zipkin-autoconfigure-ui</artifactId>
                <version>2.11.8</version>
            </dependency>

### 配置 ###

@EnableEurekaClient #注意是client，pom也要引入 client
    @EnableZipkinServer #已经过期

#关闭自动收集web请求 ，当然 eureka server还是要配置的
    management:
      metrics:
        web:
          server:
            auto-time-requests: false

## 2. 构建 user Service ##

### pom ###

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

### yaml ###

spring:
      application:
        name: eureka-feign-client
    
      sleuth:
        web:
          client:
            enabled: true
        sampler:
          probability: 1.0 # 将采样比例设置为 1.0，也就是全部都需要。默认是 0.1
      zipkin:
        base-url: http://localhost:9411/ # 指定了 Zipkin 服务器的地址

### 构建 gateway service ###

*  同理 引入 zuul，web，zipkin

zuul:
      routes:
        hiapi:
          path: /hiapi/**
          serviceId: eureka-client
          
    @EnableZuulProxy
    和 上面的 sleuth配置

*  就用 feign调用，也可以。都注册到同一个 eureka

## 3. 使用 RabbitMq传输 链路 ##

### pom ###

<dependency>
    			<groupId>org.springframework.cloud</groupId>
    			<artifactId>spring-cloud-stream-binder-rabbit</artifactId>
    		</dependency> #实例中引用的是 这个
    
    
    		<dependency>
    			<groupId>org.springframework.cloud</groupId>
    			<artifactId>spring-cloud-stream-binder-rabbit</artifactId>
    		</dependency> #除了 zk 和 sleuth ，在引用这个
    
    		# 这个项目中，并没引用
    		<dependency>
    			<groupId>org.springframework.cloud</groupId>
    			<artifactId>spring-cloud-sleuth-zipkin-stream</artifactId>
    			<version>1.3.2.RELEASE</version> 
    		</dependency>

### yaml 和 开启 ###

spring:
      application:
        name: eureka-feign-client
      rabbitmq:
        host: localhost
        username: guest
        password: guest
        port: 5672
      sleuth:
        web:
          client:
            enabled: true
        sampler:
          probability: 1.0 # 将采样比例设置为 1.0，也就是全部都需要。默认是 0.1
      zipkin:
        base-url: http://localhost:9411/ # 指定了 Zipkin 服务器的地址

### client端也是这样引用 ###

#### 引入pom ####

## 4. 在 mysql中 存储链路数据 ##

> 支持 mysql elasticsearch cassandra

### zipkin-server改造 ###

<dependency>
                <groupId>io.zipkin.java</groupId>
                <artifactId>zipkin-server</artifactId>
                <version>2.11.8</version>
                <exclusions>
                    <exclusion>
                        <groupId>org.apache.logging.log4j</groupId>
                        <artifactId>log4j-slf4j-impl</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>
            <dependency>
                <groupId>io.zipkin.java</groupId>
                <artifactId>zipkin-autoconfigure-ui</artifactId>
                <version>2.11.8</version>
            </dependency>
    #这些不变
    
    
            <dependency>
                <groupId>io.zipkin.java</groupId>
                <artifactId>zipkin-storage-mysql</artifactId>
                <version>2.4.1</version>
            </dependency> 引入存储
    
            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-jdbc</artifactId>
            </dependency> #mysql引入不变

配置mysql
    创建MySQLStorage 类，用 @Bean方法

## 5. ElasticSearch 存储链路数据 ##

<dependency>
    			<groupId>io.zipkin.java</groupId>
    			<artifactId>zipkin-autoconfigure-storage-elasticsearch-http</artifactId>
    			<version>2.4.1</version>
    		</dependency>
    		<dependency>
    			<groupId>io.zipkin.java</groupId>
    			<artifactId>zipkin</artifactId>
    			<version>2.4.0</version>
    		</dependency>

还要配置yaml

elasticSearch 的端口是 9200

Kibana 的端口是 5601
