Mysql作为后端存储

vi /opt/app/skywalking/config/application.yml

storage:
  #selector: ${SW_STORAGE:h2}
  selector: ${SW_STORAGE:mysql}
..............................
  mysql:
    properties:
      jdbcUrl: ${SW_JDBC_URL:"jdbc:mysql://localhost:3306/db_apm?rewriteBatchedStatements=true"}
      dataSource.user: ${SW_DATA_SOURCE_USER:root}
      dataSource.password: ${SW_DATA_SOURCE_PASSWORD:root@1234}

依赖包

官方是没有mysql的包的。去下载：

###
create database db_apm;

## 依赖驱动包下载地址
https://mvnrepository.com/artifact/mysql/mysql-connector-java/8.0.28


## 
mysql-connector-java-8.0.28.jar

## jar放到以下目录
/opt/app/skywalking/oap-libs/

客户端接入

Java-agent

##
tar -xzvf apache-skywalking-apm-9.3.0.tar.gz  
tar -zxvf apache-skywalking-java-agent-8.15.0.tgz


##接入方法：  java-ops
-javaagent:/skywalking/skywalking-agent/skywalking-agent.jar # jar包位置
-DSW_AGENT_NAME=dev::demo2 # 前面的代表分组，后面的是项目名称
-DSW_AGENT_COLLECTOR_BACKEND_SERVICES=127.0.0.1:11800 # 数据接入点

# 每个项目需要拷贝一份skywalking-agent.jar
