mvnw是什么

mvnw是Maven Wrapper的缩写。因为我们安装Maven时，默认情况下，系统所有项目都会使用全局安装的这个Maven版本。但是，对于某些项目来说，它可能必须使用某个特定的Maven版本，这个时候，就可以使用Maven Wrapper，它可以负责给这个特定的项目安装指定版本的Maven，而其他项目不受影响。
简单地说，Maven Wrapper就是给一个项目提供一个独立的，指定版本的Maven给它使用。

1. Skywalking OAP 配置集群

环境变量表：https://skywalking.apache.org/docs/main/v8.4.0/en/setup/backend/configuration-vocabulary/
参考官方文档：https://skywalking.apache.org/docs/main/v8.4.0/en/setup/backend/backend-cluster/#nacos

使用docker镜像配置

1.1 增加nacos配置

nacos01:
    image: nacos/nacos-server:${NACOS_VERSION}
    container_name: nacos01
    networks:
      skywalking_networks:
        ipv4_address: 192.168.200.30
    volumes:
      - ./nacos/nacos01/logs:/home/nacos/logs
      - ./nacos/init.d/custom.properties:/home/nacos/init.d/custom.properties

1.2 配置两个oap，复制两个

在skywalking download页面找到：https://skywalking.apache.org/downloads/#docker-images-for-convenience

  skywalking-oap01:
    image: apache/skywalking-oap-server:${TAG}
    container_name: skywalking-oap01
    depends_on:
      - es01
      - es02
      # - es03
      - nacos01
      - nacos02
      - nacos03
    volumes:
      - "./skywalking/oap/oap01/config:/skywalking/config"
    ports:
      - 11801:11800
      - 12801:12800
    expose:
      - "11800"
      - "12800"
    environment:
      JAVA_OPTS: " -Xms256M -Xmx1024M"
      # es7存储
      SW_STORAGE: elasticsearch7
      SW_STORAGE_ES_CLUSTER_NODES: 192.168.200.10:9200,192.168.200.11:9200,192.168.200.12:9200
      # 健康检查
      SW_HEALTH_CHECKER: default
      # telemetry 与 prometheus
      SW_TELEMETRY: prometheus
      # 需要更改self->staticConfig->targets->url为当前容器名
      # SW_PROMETHEUS_FETCHER: default
      TZ: Asia/Shanghai

 skywalking-oap02:
    image: apache/skywalking-oap-server:${TAG}
    container_name: skywalking-oap01
    depends_on:
      - es01
      - es02
      # - es03
      - nacos01
      - nacos02
      - nacos03
    volumes:
      - "./skywalking/oap/oap01/config:/skywalking/config"
    ports:
      - 11801:11800
      - 12801:12800
    expose:
      - "11800"
      - "12800"
    environment:
      JAVA_OPTS: " -Xms256M -Xmx1024M"
      # es7存储
      SW_STORAGE: elasticsearch7
      SW_STORAGE_ES_CLUSTER_NODES: 192.168.200.10:9200,192.168.200.11:9200,192.168.200.12:9200
      # 健康检查
      SW_HEALTH_CHECKER: default
      # telemetry 与 prometheus
      SW_TELEMETRY: prometheus
      # 需要更改self->staticConfig->targets->url为当前容器名
      # SW_PROMETHEUS_FETCHER: default
      TZ: Asia/Shanghai

1.3 配置环境变量

environment:
      SW_CLUSTER: nacos
      SW_CLUSTER_NACOS_HOST_PORT: 192.168.200.30:8848,192.168.200.31:8848,192.168.200.32:8848
      SW_CLUSTER_NACOS_USERNAME: nacos
      SW_CLUSTER_NACOS_PASSWORD: nacos
      SW_CLUSTER_NACOS_INTERNAL_COM_HOST: 192.168.200.100
      SW_CLUSTER_NACOS_INTERNAL_COM_PORT: 11800

2. Skywalking OAP 动态配置并验证

Dynamic Confirguration：https://github.com/apache/skywalking/blob/master/docs/en/setup/backend/dynamic-config.md

可动态配置的参数包含：

  • 指定多少ms内为DB慢查询
  • gateways
  • 告警设置
  • apdex
  • endpoint分组名
  • 采样率
  • 慢链路的延时
  • [configuration-discovery.md](https://github.com/apache/skywalking/blob/master/docs/en/setup/service-agent/java-agent/configuration-discovery.md) 网关或代理

动态配置需要一个配置中心，这里我们选用nacos，参考官网文档：https://github.com/apache/skywalking/blob/master/docs/en/setup/backend/dynamic-config.md#dynamic-configuration-nacos-implementation

Docker文件中增加配置

      SW_CONFIGURATION: nacos
      SW_CONFIG_NACOS_SERVER_ADDR: nacos01
      SW_CONFIG_NACOS_SERVER_PORT: 8848
      SW_CONFIG_NACOS_SERVER_GROUP: skywalking
      SW_CONFIG_NACOS_SERVER_NAMESPACE: skywalking
      SW_CONFIG_NACOS_USERNAME: nacos
      SW_CONFIG_NACOS_PASSWORD: nacos

Nacos添加配置image.png

3. 启动 live-demo 项目，访问测试端点，在 UI 上验证

  • curl "http://localhost:8764/projectA/test"
