加载数据
=================

    1. 注意本地路径装载在Docker中的路径

        .. code-block:: yaml
            :linenos:

            $ cat container-dtc-nwp/components/metviewer/docker-compose.yaml
            ...
            metviewer:
                image: metviewer
                container_name: metviewer
                ports:
                - "8080:8080"
                volumes:
                  - /home/wrf/container-dtc-nwp/components/scripts:/scripts
                  - /home/wrf/METout:/data
            ...

    #. 检查 :code:`container-dtc-nwp/components/scripts/common/load_metv_TMPL.xml` 中的路径设置，MET运行结果应该放在相应的目录下

        .. code-block:: xml
            :linenos:
            :emphasize-lines: 10, 26-30

            <load_spec>
              <connection>
                <management_system>mysql</management_system>
                <host>mysql_mv:3306</host>
                <database>DATABASE_NAME</database>
                <user>root</user>
                <password>mvuser</password>
              </connection>

                    <folder_tmpl>/data/{met_tool}</folder_tmpl>

                    <met_version>V6.0</met_version>

                    <verbose>false</verbose>
                    <insert_size>1</insert_size>
                    <mode_header_db_check>false</mode_header_db_check>
                    <drop_indexes>false</drop_indexes>
                    <apply_indexes>true</apply_indexes>

                    <load_stat>true</load_stat>
                    <load_mode>true</load_mode>
                    <load_mpr>false</load_mpr>
                    <load_orank>false</load_orank>

                    <load_val>
                            <field name="met_tool">
                                    <val>grid_stat</val>
                                    <val>point_stat</val>
                                    <val>ensemble_stat</val>
                                    <val>mode</val>
                            </field>
                    </load_val>

            </load_spec>


    #. 装载数据到数据库

        .. note::

            请确保 metviewer Docker 正在运行

        .. code-block:: bash

            $ docker exec -it metviewer /scripts/common/metv_load_all.ksh mv_rap

        该命令将 :code:`/home/wrf/METout` 下的结果加载到METViewer的数据库中

    #. 检查数据是否加载成功
    
        - 打开网页浏览器，输入网址 ：http://localhost:8080/metviewer/metviewer1.jsp 或 http://10.86.41.176:8080/metviewer/metviewer1.jsp

        - 应该可以看到如下页面
