zipkinmysql表结构

zipkin的数据存储可以存在4个地方：

内存（仅用于测试，数据不会持久化，zipkin-server关掉，数据就没有了）
- 这也是之前使用的

mysql
- 可能是最熟悉的方式

Cassandra

一、代码（基于第二十八章 springboot + zipkin（brave定制-AsyncHttpClient））

1、pom.xml

1         <dependency>
2             <groupId>io.zipkin.brave</groupId>
3             <artifactId>brave-mysql</artifactId>
4             <version>3.9.0</version>
5         </dependency>

2、ZipkinConfig添加如下

1     @Bean
2     public MySQLStatementInterceptorManagementBean mySQLStatementInterceptorManagementBean(Brave brave) {
3         return new MySQLStatementInterceptorManagementBean(brave.clientTracer());
4     }

二、数据库

1、建库

自己创建库（eg.mytestdb）就好

2、建表

在mytestdb中执行zipkin准备好的脚本mysql.sql来创建三张表以及各个索引。

mysql.sql位置：https://github.com/openzipkin/zipkin/blob/master/zipkin-storage/mysql/src/main/resources/mysql.sql

或者直接将整个zipkin项目克隆下来，再进去看内容。

mysql.sql内容如下：

1 CREATE TABLE IF NOT EXISTS zipkin_spans (
 2   `trace_id` BIGINT NOT NULL,
 3   `id` BIGINT NOT NULL,
 4   `name` VARCHAR(255) NOT NULL,
 5   `parent_id` BIGINT,
 6   `debug` BIT(1),
 7   `start_ts` BIGINT COMMENT "Span.timestamp(): epoch micros used for endTs query and to implement TTL",
 8   `duration` BIGINT COMMENT "Span.duration(): micros used for minDuration and maxDuration query"
 9 ) ENGINE=InnoDB ROW_FORMAT=COMPRESSED;
10 
11 ALTER TABLE zipkin_spans ADD UNIQUE KEY(`trace_id`, `id`) COMMENT "ignore insert on duplicate";
12 ALTER TABLE zipkin_spans ADD INDEX(`trace_id`, `id`) COMMENT "for joining with zipkin_annotations";
13 ALTER TABLE zipkin_spans ADD INDEX(`trace_id`) COMMENT "for getTracesByIds";
14 ALTER TABLE zipkin_spans ADD INDEX(`name`) COMMENT "for getTraces and getSpanNames";
15 ALTER TABLE zipkin_spans ADD INDEX(`start_ts`) COMMENT "for getTraces ordering and range";
16 
17 CREATE TABLE IF NOT EXISTS zipkin_annotations (
18   `trace_id` BIGINT NOT NULL COMMENT "coincides with zipkin_spans.trace_id",
19   `span_id` BIGINT NOT NULL COMMENT "coincides with zipkin_spans.id",
20   `a_key` VARCHAR(255) NOT NULL COMMENT "BinaryAnnotation.key or Annotation.value if type == -1",
21   `a_value` BLOB COMMENT "BinaryAnnotation.value(), which must be smaller than 64KB",
22   `a_type` INT NOT NULL COMMENT "BinaryAnnotation.type() or -1 if Annotation",
23   `a_timestamp` BIGINT COMMENT "Used to implement TTL; Annotation.timestamp or zipkin_spans.timestamp",
24   `endpoint_ipv4` INT COMMENT "Null when Binary/Annotation.endpoint is null",
25   `endpoint_ipv6` BINARY(16) COMMENT "Null when Binary/Annotation.endpoint is null, or no IPv6 address",
26   `endpoint_port` SMALLINT COMMENT "Null when Binary/Annotation.endpoint is null",
27   `endpoint_service_name` VARCHAR(255) COMMENT "Null when Binary/Annotation.endpoint is null"
28 ) ENGINE=InnoDB ROW_FORMAT=COMPRESSED;
29 
30 ALTER TABLE zipkin_annotations ADD UNIQUE KEY(`trace_id`, `span_id`, `a_key`, `a_timestamp`) COMMENT "Ignore insert on duplicate";
31 ALTER TABLE zipkin_annotations ADD INDEX(`trace_id`, `span_id`) COMMENT "for joining with zipkin_spans";
32 ALTER TABLE zipkin_annotations ADD INDEX(`trace_id`) COMMENT "for getTraces/ByIds";
33 ALTER TABLE zipkin_annotations ADD INDEX(`endpoint_service_name`) COMMENT "for getTraces and getServiceNames";
34 ALTER TABLE zipkin_annotations ADD INDEX(`a_type`) COMMENT "for getTraces";
35 ALTER TABLE zipkin_annotations ADD INDEX(`a_key`) COMMENT "for getTraces";
36 
37 CREATE TABLE IF NOT EXISTS zipkin_dependencies (
38   `day` DATE NOT NULL,
39   `parent` VARCHAR(255) NOT NULL,
40   `child` VARCHAR(255) NOT NULL,
41   `call_count` BIGINT
42 ) ENGINE=InnoDB ROW_FORMAT=COMPRESSED;
43 
44 ALTER TABLE zipkin_dependencies ADD UNIQUE KEY(`day`, `parent`, `child`);

执行脚本之后，数据库出现三张表，如下：

三、启动命令

STORAGE_TYPE=mysql MYSQL_HOST=192.192.192.192 MYSQL_TCP_PORT=3306 MYSQL_DB=mytestdb MYSQL_USER=root MYSQL_PASS=123456 nohup java -jar zipkin-server-1.5.1-exec.jar &
- STORAGE_TYPE：存储类型，这里是mysql
- MYSQL_HOST和MYSQL_TCP_PORT：创建connection
- MYSQL_USER和MYSQL_PASS：用户名和密码

四、测试

启动4个service，然后swagger测试，最后查看zipkin和数据库表即可。
