docker部署zipkin

一. 概述

  Zipkin 是一个开放源代码分布式的跟踪系统，每个服务向zipkin报告计时数据，zipkin会根据调用关系通过Zipkin UI生成依赖关系图。

  zikin到了2.*版本之后是不建议自己去创建zipkin的服务的，官方提供了服务包，可以直接下载启动，只需要进行配置文件的配置就可以了。

二. 准备

1> 数据库

  数据库怎么创建部署这里就不说了。可以查看先前的文档。创建数据库dawn-zipkin,然后运行下面的sql语句创建表格。

2> rabbitmq

  由于我们这里采用的队列进行的数据交换，所以这里也要创建一个队列。至于队列的创建可以查看先前的文档。

3> 创建目录

/home/docker/zipkin

4> 创建zipkin-compose.yml文件

# This file uses the version 2 docker-compose file format, described here:
# https://docs.docker.com/compose/compose-file/#version-2
#
# This runs the zipkin and zipkin-mysql containers, using docker-compose's
# default networking to wire the containers together.
#
# Note that this file is meant for learning Zipkin, not production deployments.
 
version: '3'
 
services:  
  zipkin:
    image: openzipkin/zipkin
    container_name: zipkin
    # Environment settings are defined here https://github.com/openzipkin/zipkin/tree/1.19.0/zipkin-server#environment-variables
    environment:
      - STORAGE_TYPE=mysql
      # Point the zipkin at the storage backend
      - MYSQL_DB=dawn_zipkin
      - MYSQL_USER=root
      - MYSQL_PASS=root
      - MYSQL_HOST=192.168.47.150
      - MYSQL_TCP_PORT=3306
      # Uncomment to enable scribe
      # - SCRIBE_ENABLED=true
      # Uncomment to enable self-tracing
      # - SELF_TRACING_ENABLED=true
      # Uncomment to enable debug logging
      # - JAVA_OPTS=-Dlogging.level.zipkin=DEBUG -Dlogging.level.zipkin2=DEBUG
      - RABBIT_ADDRESSES=192.168.47.150:5672
      - RABBIT_USER=admin
      - RABBIT_PASSWORD=admin
      - RABBIT_QUEUE=zipkin
    
    ports:
      # Port used for the Zipkin UI and HTTP Api
      - 9411:9411
      # Uncomment if you set SCRIBE_ENABLED=true
      # - 9410:9410

将该文件放在/home/docker/zipkin目录下

三. 启动

进入到/home/docker/zipkin目录下执行下面的命令：

docker-compose -f zipkin-compose.yml up -d

赶紧检测启动是否成功吧
