Upgrade Pandora in EDAS

On the Application Details page, click Container Version, find the latest version, and then click Upgrade to This Version.

Upgrade Pandora in Ali-Tomcat + Pandora

If you developed your application in Ali-Tomcat + Pandora, perform the following steps to upgrade Pandora.

  1. Download Pandora of the required version. For more information, see EDAS-Container release notes.
  2. Run the following command to delete the Pandora files of the existing version:
    rm -rf /home/admin/tomcat/deploy/taobao-hsf.sar

    /home/admin/tomcat is the default installation directory of Ali-Tomcat.

    You must install Pandora in the installation directory of Ali-Tomcat. If Ali-Tomcat is not installed in the default installation directory, specify the actual directory in the command.

  3. Run the following command to move the downloaded Pandora package to the deploy folder of Ali-Tomcat:
    mv /home/admin/downloads/taobao-hsf.tgz /home/admin/tomcat/deploy
    • /home/admin/downloads/taobao-hsf.tgz is the directory where Pandora is downloaded on your on-premises machine.
    • /home/admin/tomcat is the installation directory of Ali-Tomcat.

    If you used other directories, specify the actual directories in the command.

  4. Run the following command to decompress the Pandora package:
    tar -zxvf /home/admin/tomcat/deploy/taobao-hsf.tgz

Upgrade Pandora in Pandora Boot

If you use Pandora in Pandora Boot, you need only to add the -u parameter for the mandatory upgrade when you package your project.

For example, when you use Maven to build a project, run mvn clean package -U in the project directory to upgrade Pandora.
