VE License Server Software Upgrade

Please note:

• If you are not familiar with the installation of RPM packages, please refer to the regular user's guide or your Linux system documentation.
• You do not need to stop running emulator instances before upgrading the license server.
• Please refer to the general Charon user's guide for information on how to upgrade the Charon emulator software.
• If the old license server was uninstalled before installing the new version (instead of performing an upgrade), the license (V2C file) must be imported again using the v2c utility.
• Important: when upgrading to version 2.4.9 or above from an older version of the license server, additional steps are required:

  • Before installing version 2.4.9 or later:

    • Backup modified VE configuration files (e.g., config.ini, non-default certificates).

    • If the VE license server runs in AutoVE mode:

      • Backup the instances.db file.

      • If on same host as SSP: check SSP and AutoVE compatibility in the Release Notes. Upgrade Charon-SSP if needed and rename the file /opt/charon-license-server (if it exists) to /opt/charon-license-server-address.

    • Uninstall the old VE version (do not use the upgrade function).

  • After installing the new version:

    • The latest xxx.v2c license file must be re-imported

    • Restore the previously saved files to the new installation directory and restart the license service.

In the description below, the placeholders used have the following meaning:

• <mykey> is the private key of the key-pair you associated with your cloud instance
  (for an on-premises VMware installation or an installation on a physical system where logging in with username/password is allowed, this is not needed).
• <user> is the user associated with your license server instance (e.g., opc on OCI, centos for a CentOS instance on AWS, or the custom user on your VMware virtual machine;
  for an instance installed from a Stromasys-provided Charon AL or VE emulator marketplace image, use user charon for SFTP and user sshuser for interactive login.
• <linux-ip> is the ip address of your license server system.
  

Perform the following steps to install the VE License Server software:

1. Copy the license server software package to the license server host (if needed):
   
   1. For example, use sftp to connect to the VE license server system.
      # sftp -i ~/.ssh/<mykey>  <user>@<linux-ip>
   2. Copy the software package to the license server system using the following SFTP command:
      > put <local-path-to-license-server-package>


2. Use ssh to log in on the license server host.
   # ssh-i ~/.ssh/<mykey> <user>@<linux-ip>
   
   
3. As a privileged user (root) go to the directory where you stored the installation package and install the package:
   1. Become the root user: # sudo -i
   2. Go to the package location:  # cd <path-to-package-directory>
If you used SFTP to copy the package to an instance installed from a prepackaged Charon marketplace image, the home directory of the charon user and the default location for file transfers is /charon/storage.
   3. Unpack the archive and agree to the end-user license agreement (EULA).
      1. For VE license server 2.2.4 and above:
         
         1. # sh ./license-server-<version>.rpm.sh
            This will display the EULA. You must agree to it to unpack the software.
         2. For version 2.2.4, the RPM installation package will be unpacked in the current directory.
         3. For version 2.2.5 and later, the EULA and the RPM package will be unpacked in a subdirectory (license-server-<version>.rpm) of the current working directory.
         4. RPM package name: license-server-<version>.rpm
      2. For VE license server 2.4.9 and above:
         
         1. # sh ./charon-license-server-<version>.rpm.sh
            This will display the EULA. You must agree to it to unpack the software.
         2. The RPM installation package will be unpacked in a subdirectory (charon-license-server-<version>) of the current working directory.
         3. RPM package name: charon-license-server-<version>.rpm
         4. Important: if this is an upgrade from a version before 2.4.9, the old version must be uninstalled first and additional post-installation steps are required. Before proceeding, review the requirements described in the overview section above and the Release Notes.
   4. Install the package: 
      1. Go to the directory in which the RPM package is located.           
      2. Linux 7.x: # yum install <license-server-package-name>
      3. Linux 8.x and later # dnf install <license-server-package-name>

Normally, the license server will restart and continue to work normally. To check the status, perform the following steps:

• Review the content of the license server log: /opt/license-server/log/license.log (VE versions before 2.4.9) or /opt/charon-license-server/log/license.log (VE version 2.4.9 or later).
• Use the ps command to check that the server is running:
  # ps -ef |grep license-server
• Starting with version 1.1.18, a new parameter to the license server is available to display the license server status:
  VE version before 2.4.9:
  # cd /opt/license-server
VE version 2.4.9 or later:
       # cd /opt/charon-license-server
Then for both versions:
  # ./license_server -s

About an hour after the installation check the emulator log files of any active instances to verify that no unexpected problem has been caused by the new version.
