10分钟SkyWalking与SpringBoot融合并整合到Linux中

1.���赖配置

        org.springframework.boot        spring-boot-starter-web        2.2.0.RELEASE               org.springframework.boot        spring-boot-starter        2.2.0.RELEASE                                    org.springframework.boot                spring-boot-starter-logging                                     org.springframework.boot        spring-boot-starter-log4j2        2.2.0.RELEASE                org.apache.skywalking        apm-toolkit-log4j-2.x        9.1.0                org.apache.skywalking        apm-toolkit-trace        9.1.0    

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

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:    image: apache/skywalking-ui:8.9.0    container_name: skywalking-ui    depends_on:      oap:        condition: service_healthy    links:      - oap    ports:      - "9090:8080"    environment:      SW_OAP_ADDRESS: http://oap:12800

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

(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

(3)授予权限

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

(4)测试安装结果

docker-compose --version

(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 

(8)测试接口即正常
