Installation on Linux

• GUI or desktop environment on the supported Linux platform.
• Ensure that you have the Linux Standard Base (LSB) package, and the following libraries on Linux: 

• Change directory to the location of the installation package.
• Extract the files and run the installation script.

cd /location_of_installer/
tar -xf ANSYSLICMAN_<version>_LINX64.tgz 
sudo ./INSTALL

• Follow the instructions and complete the installation. 

Silent Installation in Linux  

• 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. Ommitting this will install the Ansys LM into the default folder in the root directory, "/ansys_inc".

Installing on non-graphical Linux systems

• 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.

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. 

sudo cp ENTERPRISELICENSING_[[verpath]]_LINX64.tgz /ansys_inc
cd /ansys_inc
sudo tar -xf ENTERPRISELICENSING_[[verpath]]_LINX64.tgz
sudo tar -xf ansyslm_linx64.tgz

License file configuration and installation

• Configure the license file with static ports for shared access as shown here.
• Copy the license file into the "license_files" folder.  

cd /location_of_licensefile/
sudo cp licensefilename /ansys_inc/shared_files/licensing/license_files/ansyslmd.lic 

Starting the Ansys LM

The Ansys license manager does not start automatically on Linux. Either configure your Linux machine to run the Ansys license manager on system startup as shown here. Or start Ansys LM manually after a system restart on a Linux machine.

• This can be done from the Ansys license management center (http://localhost:1084) on the license server. 

Linux terminal/command line 

sudo /ansys_inc/shared_files/licensing/start_ansysli

Stopping the Ansys LM

• Stopping the Ansys license manager can be done from the Ansys LMCenter (http://localhost:1084) on the license server. 

Linux terminal/command line

sudo /ansys_inc/shared_files/licensing/stop_ansysli

Check license server status and license usage

• The Ansys license manager status and license usage can be checked from the Ansys license management center while logged in to the license server.
• Open the Ansys license management center and navigate to "View Current License Usage" on the left column. The current license usage on this LM will be shown. Click on "Show tabular data" for a table format. 

• Alternatively, navigate to the Diagnostics section, "Display FlexNet License Status". This will show the FlexNet status and lists of license features for check out and the user information that has checked out the license (if any). 

Linux terminal/command line

/ansys_inc/shared_files/licensing/linx64/ansysli_server -k info
/ansys_inc/shared_files/licensing/linx64/lmutil lmstat -a -c 1055@localhost
