在Linux环境中调测ClickHouse应用（MRS 3.3.0及之后版本）

ClickHouse应用程序也支持在Linux环境中运行。在程序代码完成开发后，您可以上传Jar包至准备好的Linux运行环境中运行。

前提条件

Linux环境已安装JDK，版本号需要和IntelliJ IDEA导出Jar包使用的JDK版本一致，并设置好Java环境变量。

编译并运行程序

  1. 单击IDEA右边Maven窗口的“Reload All Maven Projects”，进行maven项目依赖import。

    图1 reload projects

  2. 导出jar包

    • 选择“Maven > clickhouse-examples > Lifecycle > clean”，双击“clean”运行maven的clean命令。
    • 选择“Maven > clickhouse-examples > Lifecycle > install”，双击“install”运行maven的insatll命令。
    图2 maven工具的clean和install

  3. 将target目录下的clickhouse-examples-*.jar文件和“clickhouse-examples”目录下的“conf”文件夹复制到ClickHouse客户端安装目录下，例如“客户端安装目录/JDBC”目录或“客户端安装目录/JDBCTransaction”目录下。

    “客户端安装目录/JDBC”目录，用来调测JDBC二次样例；

    “客户端安装目录/JDBCTransaction”目录，用来调测事务二次样例。

  4. 登录客户端节点，进入jar文件上传目录下，修改文件权限为700。

    cd 客户端安装目录/JDBC

    或：cd 客户端安装目录/JDBCTransaction

    chmod 700 clickhouse-examples-*.jar

  5. 在“clickhouse_examples-*.jar”所在客户端目录下执行如下命令运行jar包：

    source 客户端安装目录/bigdata_env

    cd 客户端安装目录/JDBC

    或：cd 客户端安装目录/JDBCTransaction

    java -jar clickhouse-examples-*.jar

查看调测结果

ClickHouse应用程序运行完成后，可通过以下方式查看程序运行情况：

  • 通过运行结果查看程序运行情况。
  • 通过ClickHouse日志获取应用运行情况。

    即查看当前jar文件所在目录的“logs/clickhouse-example.log”日志文件，例如“客户端安装目录/JDBC/logs/clickhouse-example.log”或“客户端安装目录/JDBCTransaction/logs/clickhouse-example.log”。

jar包运行结果如下：
