Commissioning a ClickHouse Application in a Linux Environment

ClickHouse applications can run in a Linux environment. After the application code is developed, you can upload the JAR file to the prepared Linux environment.

Prerequisites

JDK has been installed on Linux. The version must be the same as JDK version of the JAR file exported from IntelliJ IDEA. Java environment variables have been set.

Compile and run applications.

  1. Export the JAR file.

    1. Log in to IntelliJ IDEA and choose File > Project Structure > Artifacts.
    2. Click the plus sign (+) and choose JAR > From modules with dependencies.

    3. Choose com.huawei.clickhouse.examples.Demo from the Main Class drop-down list and click OK.

    4. Choose Build > Build Artifacts.... After the compilation is successful, view and obtain all JAR files in the clickhouse-examples\out\artifacts\ directory.

  2. Copy all JAR files in the clickhouse-examples\out\artifacts\clickhouse_examples.jar directory and the conf folder in the clickhouse-examples directory to the ClickHouse client installation directory, for example, Client installation directory/JDBC.
  3. Log in to the client node, go to the directory where the JAR file is uploaded, and change the file permission to 700.

    cd /opt/client

    chmod 700 clickhouse-examples.jar

  4. In the client directory where clickhouse_examples.jar is stored, run the following commands to run the JAR file:

    source Client installation directory/bigdata_env

    java -cp ./*:conf/clickhouse-example.properties com.huawei.clickhouse.examples.Demo

Viewing Commissioning Results

After a ClickHouse application is run, you can use one of the following methods to view the running result:

  • Viewing the command output
  • Viewing ClickHouse logs

    That is, view the logs/clickhouse-example.log file in the directory where the current JAR file is located, for example, Client installation directory/JDBC/logs/clickhouse-example.log.

    The execution result of the JAR file is as follows:
