## 1 Obtain the installation package and install it

    By getting the installation package of the corresponding module in our release installation package:

````bash
 ## 1. Unzip the installation package
tar -xvzf wedatasphere-linkis-0.11.0-dist.tar.gz
cd wedatasphere-linkis-0.11.0-dist
 ## 2. Select the corresponding service installation package and go to the corresponding installation directory: $SERVER_HOME
cp wedatasphere-linkis-0.11.0-dist/share/linkis/linkis-publicservice/linkis-publicservice.zip $SERVER_HOME
 ## 3. Copy the installation package to the corresponding installation directory. For example: publicservice needs to copy linkis-publicservice.zip
 ## Decompress the corresponding service
unzip $SERVERNAME.zip
 ## 4. The module package is a public package, except for gateway and Eureka, everything else needs to be copied.
cp ${workDir}/share/linkis/module/module.zip $SERVER_HOME
 ## 5. Unzip the module package
cd $SERVER_HOME/;unzip module.zip> /dev/null;
 ## 6. Copy the corresponding installation package
cp module/lib/* $SERVER_HOME/$SERVERNAME/lib/

````
