10分钟SkyWalking与SpringBoot融合并整合到Linux中

1.依赖配置

<dependency>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starter-webartifactId>
        <version>2.2.0.RELEASEversion>

        <groupId>org.springframework.bootgroupId>

        <exclusions>
            <exclusion>
                <groupId>org.springframework.bootgroupId>

这边需要排除掉springboot自带的日志框架，很重要
2.配置日志文件
在/src/main/resources下创建log4j2.xml文件

<Configuration status="INFO">
    <Appenders>
        
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d [%traceId] %-5p %c{1}:%L - %m%n"/>
        Console>
        
        <GRPCLogClientAppender name="grpc-log">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
        GRPCLogClientAppender>
    Appenders>
    <Loggers>
        <Root level="INFO">
            <AppenderRef ref="Console"/>
            <AppenderRef ref="grpc-log"/>
        Root>
    Loggers>

3.Dockfile文件编写

version: '3.8'
services:
  elasticsearch:
    image: elasticsearch:7.16.2
    container_name: elasticsearch
    ports:
      - "9201:9200"
    healthcheck:
      test: [ "CMD-SHELL", "curl --silent --fail localhost:9200/_cluster/health || exit 1" ]
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 10s
    environment:
      - discovery.type=single-node
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - ./data/es_data:/usr/share/elasticsearch/data

  oap:
    image: apache/skywalking-oap-server:8.9.0
    container_name: oap
    depends_on:
      elasticsearch:
        condition: service_healthy
    links:
      - elasticsearch
    ports:
      - "11800:11800"
      - "12800:12800"
    healthcheck:
      test: [ "CMD-SHELL", "/skywalking/bin/swctl ch" ]
      interval: 30s
      timeout: 10s
      retries: 3
      start_period: 10s
    environment:
      SW_STORAGE: elasticsearch
      SW_STORAGE_ES_CLUSTER_NODES: elasticsearch:9200
      SW_HEALTH_CHECKER: default
      SW_TELEMETRY: prometheus
      JAVA_OPTS: "-Xms1024m -Xmx1024m"
  skywalking-ui:

dockerfile如何运行，自行查询即可
启动完成之后，打开http://127.0.0.1:9090,会出现Skywalking的UI界面
4.VM参数
在虚拟机参数里加上这段，注意skywalking-agent.jar要去官网下载，jar包外面的文件也不能丢失，否则会报错

-javaagent:C:/skywalking/skywalking-agent/skywalking-agent.jar
-Dskywalking.agent.service_name=你自己的服务名字
-Dskywalking.collector.backend_service=127.0.0.1:11800

5.请求展示
请求查询接口，记得日志要打在service层里面

6.部署到Linux中
(1)一键安装docker,注意Centos版本要大于等于7

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
1

(2)安装docker-compose

sudo curl -L "https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
1

(3)授予权限

sudo chmod +x /usr/local/bin/docker-compose
1

(4)测试安装结果

docker-compose --version
1

(5)之后上传之前的dockerfile文件，在当前目录下执行docker-compose up -d
(6)查看服务器的9090端口，skywalkingui是否工作正常
(7)上传测试项目，执行

java -javaagent:/root/skywalking-agent/skywalking-agent.jar -Dskywalking.agent.service_name=gwt -Dskywalking.collector.backend_service=127.0.0.1:11800 -jar TestSkyWalking.jar 
1

(8)测试接口即正常
