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Apollo官网传送门)

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。

第一步，下载github.com/ctripcorp/a…
第二步，下载adminservice、configservice和portal三个zip包之后，上传到服务器。
第三部，在服务器中安装mysql,并创建数据库，脚本传送门
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

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
          2 SERVICE_NAME=apollo-portal
      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}

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serverconfig`中 `apollo.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/）

第一步：创建项目，具体查看使用指南传送门)

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～
