环境：
jdk1.8；spring boot2.0.3；spring cloud（Finchley.RELEASE版本）;Maven3.3
摘要说明：
zipkin默认保存的内存里，在微服务架构中肯定是不行的，本篇讲述将链路信息保存到mysql数据库中
步骤：
1.创建zipkinServer4Mysql服务
添加pom.xml依赖
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<!-- 这是mysql驱动，如果自己配置也行，加这个依赖也行 -->
<dependency>

</dependency>
</dependencies>
</project>2.配置zipkinServer4Mysql服务
使用@EnableZipkinServer注解开启zipkin配置：
import javax.sql.DataSource;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import zipkin.server.internal.EnableZipkinServer;
import zipkin2.storage.mysql.v1.MySQLStorage;
@SpringBootApplication
@EnableZipkinServer
public class ZipkinServer4MysqlApplication {
public static void main(String[] args) {
SpringApplication.run(ZipkinServer4MysqlApplication.class, args);
}
@Bean
public MySQLStorage mySQLStorage(DataSource datasource) {
return MySQLStorage.newBuilder().datasource(datasource).executor(Runnable::run).build();
}
}
配置application.properties
#配置服务及端口（默认9411）
spring.application.name=zipkin-server-mysql
server.port=9411
#去除控制台异常
management.metrics.web.server.auto-time-requests=false
#配置在数据库创建完以后，可以删除，不然每次都会寻找这个sql，耗费时间。
zipkin.storage.type=mysql
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/testspringboot
spring.datasource.username=root
spring.datasource.password=cc6688211
spring.datasource.initialize=false
spring.datasource.continueOnError=true
sleuth.enabled=false
3.新建mysql表结构
先建mysql表：
CREATE TABLE IF NOT EXISTS zipkin_spans (
`trace_id_high` BIGINT NOT NULL DEFAULT 0 COMMENT 'If non zero, this means the trace uses 128 bit traceIds instead of 64 bit',
`trace_id` BIGINT NOT NULL,
`id` BIGINT NOT NULL,
`name` VARCHAR(255) NOT NULL,
`parent_id` BIGINT,
`debug` BIT(1),
`start_ts` BIGINT COMMENT 'Span.timestamp(): epoch micros used for endTs query and to implement TTL',
`duration` BIGINT COMMENT 'Span.duration(): micros used for minDuration and maxDuration query'
) ENGINE=InnoDB ROW_FORMAT=COMPRESSED CHARACTER SET=utf8 COLLATE utf8_general_ci;
ALTER TABLE zipkin_spans ADD UNIQUE KEY(`trace_id_high`, `trace_id`, `id`) COMMENT 'ignore insert on duplicate';
ALTER TABLE zipkin_spans ADD INDEX(`trace_id_high`, `trace_id`, `id`) COMMENT 'for joining with zipkin_annotations';
ALTER TABLE zipkin_spans ADD INDEX(`trace_id_high`, `trace_id`) COMMENT 'for getTracesByIds';
ALTER TABLE zipkin_spans ADD INDEX(`name`) COMMENT 'for getTraces and getSpanNames';
ALTER TABLE zipkin_spans ADD INDEX(`start_ts`) COMMENT 'for getTraces ordering and range';
CREATE TABLE IF NOT EXISTS zipkin_annotations (
`trace_id_high` BIGINT NOT NULL DEFAULT 0 COMMENT 'If non zero, this means the trace uses 128 bit traceIds instead of 64 bit',
`trace_id` BIGINT NOT NULL COMMENT 'coincides with zipkin_spans.trace_id',
`span_id` BIGINT NOT NULL COMMENT 'coincides with zipkin_spans.id',
`a_key` VARCHAR(255) NOT NULL COMMENT 'BinaryAnnotation.key or Annotation.value if type == -1',
`a_value` BLOB COMMENT 'BinaryAnnotation.value(), which must be smaller than 64KB',
`a_type` INT NOT NULL COMMENT 'BinaryAnnotation.type() or -1 if Annotation',
`a_timestamp` BIGINT COMMENT 'Used to implement TTL; Annotation.timestamp or zipkin_spans.timestamp',
`endpoint_ipv4` INT COMMENT 'Null when Binary/Annotation.endpoint is null',
`endpoint_ipv6` BINARY(16) COMMENT 'Null when Binary/Annotation.endpoint is null, or no IPv6 address',
`endpoint_port` SMALLINT COMMENT 'Null when Binary/Annotation.endpoint is null',
`endpoint_service_name` VARCHAR(255) COMMENT 'Null when Binary/Annotation.endpoint is null'
) ENGINE=InnoDB ROW_FORMAT=COMPRESSED CHARACTER SET=utf8 COLLATE utf8_general_ci;
ALTER TABLE zipkin_annotations ADD UNIQUE KEY(`trace_id_high`, `trace_id`, `span_id`, `a_key`, `a_timestamp`) COMMENT 'Ignore insert on duplicate';
ALTER TABLE zipkin_annotations ADD INDEX(`trace_id_high`, `trace_id`, `span_id`) COMMENT 'for joining with zipkin_spans';
ALTER TABLE zipkin_annotations ADD INDEX(`trace_id_high`, `trace_id`) COMMENT 'for getTraces/ByIds';
ALTER TABLE zipkin_annotations ADD INDEX(`endpoint_service_name`) COMMENT 'for getTraces and getServiceNames';
ALTER TABLE zipkin_annotations ADD INDEX(`a_type`) COMMENT 'for getTraces';
ALTER TABLE zipkin_annotations ADD INDEX(`a_key`) COMMENT 'for getTraces';
CREATE TABLE IF NOT EXISTS zipkin_dependencies (
`day` DATE NOT NULL,
`parent` VARCHAR(255) NOT NULL,
`child` VARCHAR(255) NOT NULL,
`call_count` BIGINT
) ENGINE=InnoDB ROW_FORMAT=COMPRESSED CHARACTER SET=utf8 COLLATE utf8_general_ci;
ALTER TABLE zipkin_dependencies ADD UNIQUE KEY(`day`, `parent`, `child`);先后启动
zipkin中心（zipkinServer）:zipkin-server(9411)
服务注册中心（eurekaServer）：eureka-server（1001）
服务提供者（sleuthEurekaDiscovery）：sleuth-eureka-client（2101）
服务消费者（sleuthRibbon）：sleuth-ribbon-consumer（3101）
多次调用http://localhost:3101/infoLog-2;
再访问zipkin中心：http://localhost:9411/zipkin/；点击Find Traces;
