篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了第二十九章 springboot + zipkin + mysql相关的知识,希望对你有一定的参考价值。

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
  • es
  • 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`);
View Code

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。
