spring boot 集成apollo 快速指南

目前市面上流行的三大配置中心框架: Spring CLoud ConfigAlibaba Nacos 以及 携程apollo , 我们相应架构组号召,就使用Apollo吧。

Work Flow

简单解释:

上图中有三套环境 FATUATPROD ,每一套环境都部署了2套 ConfigserviceAdminservice .使用统一的 Portal Server Cluster 对所有环境进行配置管理。如我们自己的配置环境:

Meta-Server(Configservice)说白一点,就是 Eureka discovery ,每一套环境对应不同的一套meta server,以此来实现环境隔离,如下图:

#因为资源有限,因此我配置的三套环境使用同一台数据库,无法实现环境隔离,但是不影响展示效果。
  local.meta=http://localhost:8080
  2 dev.meta=http://localhost:8080
  4 uat.meta=http://localhost:8080
  6 pro.meta=http://localhost:8080

如图2所示。

Configure Server

apollo 服务端主要有三个Spring Boot项目 和两个数据库组成:

  • apollo-configservice(默认端口:8080)

    提供配置的读取、推送等功能,服务对象是Apollo客户端

  • apollo-adminservice(默认端口:8090)

    提供配置的修改、发布等功能,服务对象是Apollo Portal(管理界面)

  • apollo-portal(默认端口:8070)

    通过域名访问Meta Server获取Admin Service服务列表(IP+Port),而后直接通过IP+Port访问服务,同时在Portal侧会做load balance、错误重试

  • apolloportaldb
  • apolloconfigdb

因为Apollo官方文档足够详细,想要了解的同学直接)

但是又因为官方文档太过详细,以至于如果只想部署的同学可能觉得稍显繁琐,因此,我这里直接开始部署服务端,就废话少说了。

  1. 第一步,下载 https://github.com/ctripcorp/apollo/releases
  2. 第二步,下载 adminserviceconfigserviceportal 三个zip包之后,上传到服务器。
  3. 第三部,在服务器中安装mysql,并创建数据库, 脚本传送门
  4. 第四步,分别配置三个Springboot服务并启动,主要配置点有3处:

    1. 数据库配置

      1 # DataSource
        2 spring.datasource.url = jdbc:mysql://localhost:3306/ApolloPortalDB?characterEncoding=utf8
        3 spring.datasource.username = wr
        4 spring.datasource.password = wr
    2. 日志路径

      • /根路径/apollo-xxxx.conf

        1 MODE=service
          2 PID_FOLDER=.
          # 这里
          3 LOG_FOLDER=/home/jing/software/apollo-portal-1.5.1/logs/100003173/
      • /script/startup.sh

        1 #!/bin/bash
3 ## Adjust log dir if necessary
      #这里
      4 LOG_DIR=/home/jing/software/apollo-portal-1.5.1/logs/100003173
      5 ## Adjust server port if necessary
      6 SERVER_PORT=${SERVER_PORT:=8070}
    ```
  1. 配置apollo-portal的meta service信息

    local.meta=http://localhost:8080
      2 dev.meta=http://localhost:8080
      4 uat.meta=http://localhost:8080
      6 pro.meta=http://localhost:8080

    这里也得修改 apolloconfigdb数据库中的表serverconfigapollo.portal.envs 的配置为: dev,uat,prod

然后apollo server就配置好了,分别启动三个服务即可!访问 http://172.16.28.177 :8070/

Configure Client

客户端使用分步骤:访问( http://172.16.28.177 :8070/)

  1. 第一步:创建项目

创建之后,如下图

具体查看)

上面不是我要说的重点,重点是如何在我们项目中使用,以broadway-gateway为例。

  • 第一步:创建bootstrap.yml,在application.yml加载之前要加载配置属性

    app:
    #重点关联,id必须是唯一的,每个service各自不同
      id: P000000001 
    apollo:
      meta: http://172.16.28.177:8080/ # apollo-configservice
      bootstrap:
        enabled: true
        namespaces: application
  • 第二步:使用配置的变量

    eureka:
      instance:
        prefer-ip-address: true
      client:
        service-url:
        # 冒号后面的baidu.com是默认值,如果无法连接apollo,可以使用默认值防止出错
          defaultZone: ${broad.gateway.eureka.server-list:http://baidu.com}

运行gateway,可以看到如下结果:

可以看到,在springboot启动之前,apollo首先加载配置信息了~

相关profile信息,后续再表,先改bug了~~
