Upgrade and uninstall obdiag

This topic describes how to upgrade and uninstall OceanBase Diagnostic Tool (obdiag).

Upgrade the software

Method 1: Upgrade obdiag that is independently deployed

If obdiag is independently deployed, you can upgrade its version based on the description in this section.

• Online upgrade (when Internet access is available)

  sudo yum update -y oceanbase-diagnostic-tool
  source /usr/local/oceanbase-diagnostic-tool/init.sh
  

  Note

  The online upgrade method is supported on CentOS 7 and 8. If you use CentOS 9, perform the following operations for offline upgrade.

• Offline upgrade (when Internet access is unavailable)

  Download the obdiag package of the latest version from OceanBase Download Center.

  yum update -y oceanbase-diagnostic-tool*.rpm
  source /usr/local/oceanbase-diagnostic-tool/init.sh
  

• Upgrade obdiag in a Debian-based system, such as Ubuntu

  Download the obdiag package of the latest version from OceanBase Download Center.

  apt-get update
  apt-get install alien -y
  alien --scripts --to-deb  oceanbase-diagnostic-tool*.rpm # Convert the RPM package to a DEB package.
  dpkg -i oceanbase-diagnostic-tool*.deb
  source /usr/local/oceanbase-diagnostic-tool/init.sh
  

Method 2: Upgrade obdiag by deploying it using obd

If the cluster to be diagnosed is deployed by using OceanBase Deployer (obd), we recommend that you upgrade obd to V2.5.0 or later. Then, you can directly run obdiag commands on obd without the need to configure the ~/.obdiag/config.yml file. For more information about the commands, see obdiag commands.

• Online upgrade (when Internet access is available)

  # Enable obd to pull remote images
  obd mirror enable remote
  # Upgrade obdiag by deploying it using obd
  obd obdiag deploy
  

• Offline upgrade (when Internet access is unavailable)

  Download the obdiag package of the latest version from OceanBase Download Center.

  # Copy the offline obdiag package to the image repository of obd
  obd mirror clone oceanbase-diagnostic-tool-xxxxxxxx.rpm
  # Upgrade obdiag by deploying it using obd
  obd obdiag deploy
  

Uninstall the software

You can uninstall obdiag only if it is independently deployed.
