Ansys license manager installation guide for Linux

This article shows the process to install the Ansys License Manager on a supported RedHat Enterprise Linux (RHEL), CentOS and SUSE Linux Enterprise Server (SLES) and Ubuntu Platforms

Requisites

  • An account with Ansys Lumerical to download the installation package.
  • Ansys license manager release 2021 R1 and newer.
  • Install the required libraries and packages shown in this Knowledge Base (KB). 

Default installation process

  • GUI or desktop environment on the supported Linux platform.
  • Download the Ansys License Manager installation package from the Ansys Customer Portal -  Downloads page (login required). 
  • Change directory to the location of the installation package.
  • Extract the files and run the installation script. (root access required)
cd /location_of_installer/
tar -xf ANSYSLICMAN_<version>_LINX64.tgz 
sudo ./INSTALL
  • Follow the instructions and complete the installation. 

See also the how-to-videos for Linux.

Silent installation 

  • Run "INSTALL" with -silent -LM argument. 
  • This will install the Ansys license manager without the GUI popup.  
./INSTALL -silent -LM -install_dir [install_path]
  • The "-install_dir [install_path]" argument is optional. Omitting this will install Ansys LM into the default folder in the root directory, "/ansys_inc" where root access is required. 
  • Add the "-install_dir [install_path]" argument to install Ansys LM on a different location where you have write access. 

Advanced (custom) installation

The installation process outlined here can be used for headless Linux machines (without GUI) or installation to a different shared folder/install path without 'root' or 'sudo' access. 

Notes: The example shown installs the Ansys License Manager into the default path in the root directory, "/ansys_inc". If you do not have root access, copy and extract the installation package into a directory where you have write access. 

  • Ensure that your machine has the LSB package and the required libraries as indicated above.
  • Download the Ansys Enterprise License Manager installation package for Linux systems from the Ansys Customer Portal - Downloads page under the Tools section. (login required) 
  • Copy the installation package into your desired directory.
  • Extract the installation files.
sudo mkdir /ansys_inc
sudo cp ENTERPRISELICENSING_[[verpath]]_LINX64.tgz /ansys_inc
cd /ansys_inc
sudo tar -xf ENTERPRISELICENSING_[[verpath]]_LINX64.tgz
sudo tar -xf ansyslm_linx64.tgz

Adding the license file

  • Copy the license file into the "license_files" folder of your Ansys LM installation. 
# e.g. "license.lic" file was saved in the user's Downloads folder
sudo cp ~/Downloads/license.lic  /ansys_inc/shared_files/licensing/license_files/

Starting/Stopping the Ansys license manager

  • The process shown below is to start/stop the license manager from the Terminal in Linux.
  • This is used if the license manager does not start automatically on system startup if this has been configured to start on system boot, as shown here. Or on servers using the Ansys license manager Enterprise edition (no Ansys LMCenter web interface).
