Centos7安装Zipkin

在使用Zipkin之前，保证已安装好docker和Docker Compose工具

使用vi命令创建docker-compose.yml文件

vi docker-compose.yml

编辑内容如下：

version: '2'

services:
  # The zipkin process services the UI, and also exposes a POST endpoint that
  # instrumentation can send trace data to. Scribe is disabled by default.
  zipkin:
    image: openzipkin/zipkin
    container_name: zipkin
    environment:
      - STORAGE_TYPE=mysql
      - MYSQL_DB=zipkin
      - MYSQL_HOST=192.168.31.136
      - MYSQL_USER=root
      - MYSQL_PASS=123456
      - 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
    ports:
      # Port used for the Zipkin UI and HTTP Api
      - 9411:9411
      # Uncomment if you set SCRIBE_ENABLED=true
      # - 9410:9410
    restart: unless-stopped

在此文件中我们使用mysql作为数据存储容器，修改mysql连接地址和用户，然后开始构建docker容器

docker-compose up -d

然后打开浏览器，访问：

http://0.0.0.0:9411

打开后，等待10s左右，如果提示以下错误

ERROR: cannot load service names: java.sql.SQLNonTransientConnectionException: (type=master) : Host is unreachable (Host unreachable)

则说明无法连接数据库，若数据库配置信息没有问题，并且能正常访问，说明有防火墙存在，不妨关闭防火墙试试可不可以访问

systemctl stop firewalld
