# How to Run the JDBC Demo Code On A Linux OS
|
||||
# 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
|
||||
<pre>sudo apt-get install maven</pre>
|
||||
```
|
||||
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.
|
||||
|
||||
## How to run jdbcChecker
|
||||
<pre>mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcChecker" -Dexec.args="-host localhost"</pre>
|
||||
|
||||
## How to run jdbcTaosDemo
|
||||
## Run jdbcDemo using mvn plugin
|
||||
run command:
|
||||
<pre> mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.jdbcTaosdemo.JdbcTaosdemo"</pre>
|
||||
```
|
||||
mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcDemo"
|
||||
```
|
||||
|
||||
and run with your customed args
|
||||
<pre>mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.jdbcTaosdemo.JdbcTaosdemo" -Dexec.args="-host localhost"</pre>
|
||||
```
|
||||
mvn clean compile exec:java -Dexec.mainClass="com.taosdata.example.JdbcDemo" -Dexec.args="-host [HOSTNAME]"
|
||||
```
|
||||
|
||||
## Compile the Demo Code and Run It
|
||||
To compile taos-jdbcdriver, go to the source directory ``TDengine/src/connector/jdbc`` and execute
|
||||
```
|
||||
mvn clean package -Dmaven.test.skip=true
|
||||
```
|
||||
|
||||
To compile the demo project, go to the source directory ``TDengine/tests/examples/JDBC/JDBCDemo`` and execute
|
||||
|
||||
<pre>
|
||||
```
|
||||
mvn clean package assembly:single
|
||||
</pre>
|
||||
```
|
||||
|
||||
The ``pom.xml`` is configured to package all the dependencies into one executable jar file.
|
||||
To run JDBCDemo.jar, go to ``TDengine/tests/examples/JDBC/JDBCDemo`` and execute
|
||||
```
|
||||
java -Djava.ext.dirs=../../../../src/connector/jdbc/target:$JAVA_HOME/jre/lib/ext -jar target/JDBCDemo-SNAPSHOT-jar-with-dependencies.jar -host [HOSTNAME]
|
||||
```
|
||||
|
||||
To run it, go to ``examples/JDBC/JDBCDemo/target`` and execute
|
||||
<pre>java -jar jdbcChecker-SNAPSHOT-jar-with-dependencies.jar -host localhost</pre>
