-# How to Run the JDBC Demo Code On Linux OS
-TDengine's JDBC demo project is organized in a Maven way so that users can easily compile, package and run the project. If you don't have Maven on your server, you may install it using
-```
-sudo apt-get install maven
-```
-
-## Install TDengine Client
-Make sure you have already installed a tdengine client on your current develop environment.
-Download the tdengine package on our website: ``https://www.taosdata.com/cn/all-downloads/`` and install the client.
-
-## Run jdbcDemo using mvn plugin
-run command:
-```
-mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcDemo"
-```
-
-and run with your customed args
-```
-mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcDemo" -Dexec.args="-host [HOSTNAME]"
-```
-
-## Compile the Demo Code and Run It
-```
-mvn clean package -Dmaven.test.skip=true
-```
-
-To run JDBCDemo.jar, execute
-```
-java -jar target/JDBCDemo-SNAPSHOT-jar-with-dependencies.jar -host [HOSTNAME]
-```
