项目总结

linux查看端口进程号命令

netstat -nltp | grep

 

当一个项目A依赖项目B，而项目B同时依赖项目C，如果项目A中因为各种原因不想引用项目C，在配置项目B的依赖时，可以排除对C的依赖。
示例（假设配置的是A的pom.xml，依赖关系为：A --> B; B --> C）：

<project>
 
  <dependencies>
    <dependency>
      <groupId>sample.ProjectB</groupId>
      <artifactId>Project-B</artifactId>
      <version>1.0</version>
      <scope>compile</scope>
      <exclusions>
        <exclusion>  <!-- declare the exclusion here -->
          <groupId>sample.ProjectC</groupId>
          <artifactId>Project-C</artifactId>
        </exclusion>
      </exclusions> 
    </dependency>
  </dependencies>
</project>

elasticsearch配置

#下载
docker pull elasticsearch:7.4.2 存储和检索数据
docker pull kibana:7.4.2 可视化检索数据


#配置
mkdir -p /mydata/elasticsearch/config
mkdir -p /mydata/elasticsearch/data
echo "http.host: 0.0.0.0" >> /mydata/elasticsearch/config/elasticsearch.yml
chmod -R 777 /mydata/elasticsearch/ 保证权限
docker run --name elasticsearch -p 9200:9200 -p 9300:9300 \
