Linux Centos7
ElasticSearch 7.8.0
SkyWalking 8.0.1

二、环境搭建

编写docker-compose.yml文件

version: '3.3'
services:
  elasticsearch:
    image: elasticsearch:7.8.0
    container_name: elasticsearch
    restart: always
    ports:
      - 9200:9200
    environment:
      discovery.type: single-node
      TZ: Asia/Shanghai
    #volumes:
    #   - ./elasticsearch/logs:/usr/share/elasticsearch/logs
    #   - ./elasticsearch/data:/usr/share/elasticsearch/data
    #   - ./elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml
    ulimits:
      memlock:
        soft: -1
        hard: -1
  oap:
    image: apache/skywalking-oap-server:8.0.1-es7
    container_name: oap
    depends_on:
      - elasticsearch
    links:
      - elasticsearch
    restart: always
    ports:
      - 11800:11800
      - 12800:12800
    environment:
      SW_STORAGE: elasticsearch7  # 指定ES版本
      SW_STORAGE_ES_CLUSTER_NODES: elasticsearch:9200
      TZ: Asia/Shanghai
    # volumes:
    #  - ./config/alarm-settings.yml:/skywalking/config/alarm-settings.yml
  ui:
    image: apache/skywalking-ui:8.0.1
    container_name: ui
    depends_on:
      - oap
    links:
      - oap
    restart: always
    ports:
      - 8080:8080
    environment:
      SW_OAP_ADDRESS: oap:12800
      TZ: Asia/Shanghai

启动docker

启动容器：docker-compose up -d

查看容器：docker-compose ps

删除容器：docker-compose rm
验证

浏览器中输入：http://localhost:8080

三、Java应用接入

探针下载
- apache-skywalking-apm-es7-8.0.1.tar.gz
- 其他版本下载
- 探针目录结构
  主要关注agent下的文件
  – config 配置文件存放位置
  – optional-plugins 选装插件，如果使用将jar文件移动到plugins下
idea配置探针
- 设置 VM options：-javaagent:/${Path}/apache-skywalking-apm-bin-es7/agent/skywalking-agent.jar
- 设置环境变量
  - SW_AGENT_NAME：项目名称
  - SW_AGENT_COLLECTOR_BACKEND_SERVICES：ip:port（oap服务地址）
