springcloud服務註冊服務總線配置服務調用簡單使用

首先參考以下幾個文檔順序完成相應的搭建，注意，除了eureka作爲服務server引入jar其它全部作爲client引入服務註冊和發現的依賴，而對於config依賴只有配置中心的服務作爲server，其它應用服務作爲client

項目搭建參考文檔：https://www.jianshu.com/p/65dfbb55779b
項目啓動參考文檔：https://blog.csdn.net/singlekingdom/article/details/91378831
服務註冊發現保證服務之間不用頻繁修改地址：https://www.cnblogs.com/luchangyou/p/7576552.html
配置中心：https://blog.51cto.com/12965378/2403913
rabbitMQ安裝（配置的實時刷新）：https://www.cnblogs.com/sam-uncle/p/9050242.html 到計算管理中心啓動rabbitmq服務到\rabbitmq_server-3.7.9\sbin 下執行命令啓動管理頁面 rabbitmq-plugins enable rabbitmq_management

執行完以上步驟後的工程結構如下：

configserver提供配置的配置中心並能夠通過rabbitmq廣播給各個服務刷新配置

eureka提供給各服務的服務註冊和發現，便於服務之間調用不用知道ip端口，只需要知道服務名稱即可

springcloudapi在此僅僅是提供服務之間交互的模型對象

springcloudconsumeruser8000服務調用方

springcloudprovideruser8001服務被調用方

以上描述的均是springcloud的子工程

@EnableConfigServer
public class ConfigApplication {

    public static void main(String[] args) {
        SpringApplication.run(ConfigApplication.class, args);
    }
}

dev提供給其它服務用的配置 config-server-dev.yml

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka
    instance:
      appname: 111網關服務1112修改了哦11166666ask
      prefer-ip-address: true
      lease-renewal-interval-in-seconds: 2
      lease-expiration-duration-in-seconds: 5

application.yml文件


server:
  port: 8888

eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://user:pass@localhost:8761/eureka

spring:
  application:
    name: config-server
  cloud:
    config:
      server:
        native:
#        必須寫絕對路徑，否則可能導致bus總線無法及時通過 /actuator/bus-refresh post請求及時刷新配置並通知所有的服務  （Content-Type application/json;charset=utf-8 此值必須設置）
          search-locations: E:/svn/springcloud/configserver/src/main/resources/config
    bus:
      enabled: true
      trace:
        enabled: true
  profiles:
    active: native
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    username: guest
    password: guest
management:
  endpoints:
    web:
      exposure:
        include: bus-refresh

配置完之後啓動服務即可

如果想要刷新配置，直接修改config-server-dev.yml文件然後調用配置中心接口/actuator/bus-refresh即可刷新所有服務的本地配置（所有服務在啓動的時候會優先從遠處獲取配置然後保存到本地，後續都用本地的配置，所以需要rabbitmq通知每個服務刷新本地配置），調用方式如下（我採用的是idea自帶的restful遠程調用根據類似於postman）：

當刷新配置的時候其它服務會打印出如下日誌，表明服務總線配置ok的

6、rabbitmq安裝，參考以上文檔即可

springcloud服務註冊服務總線配置服務調用簡單使用

製作docker pt-online-schema-change修改表結構工具鏡像

mysql數據庫全量備份和增量備份（docker容器部署方式）

docker部署kafka監控服務kafka-exporter

普通安裝和docker安裝process-exporter對linux進程進行監控
