Introduction

This document is intended to help configure and install the NanoXplore License Manager Daemon (NXLMD) required to use NanoXplore tools.

Although it should work as expected on any recent 64 bit Linux or Windows operating system, the NanoXplore License Manager Daemon has been successfully tested on the following systems:

• RedHat Enterprise Linux 7 and 8

• Ubuntu 18.04 LTS and 20.04 LTS

• Windows Server

For any other distribution or platform, please contact the NanoXplore Support team at support@nanoxplore.com.

Package Description

The NXLMD-2.2-linux.tar.gz package contains the following directories:

The NXLMD-2.2-windows.zip package contains the following directories:

Installation

Linux

In this document we refer to the directory where the NXLMD files are installed as the installation directory.

Archive

• If the installation directory does not exist, create it using the command below:

  $> mkdir /opt/NanoXplore

To install the NanoXplore License Manager Daemon:

• Unpack NXLMD-2.2-linux.tar.gz file into the installation directory using the following command:

  $> tar xzvf NXLMD-2.2-linux.tar.gz -C /opt/NanoXplore

Linux Distribution Adaptation

The NanoXplore License Manager Daemon supports several Linux distributions, you must point to the right one when updating the symbolic links in the directory /opt/NanoXplore/NXLMD/2.2/bin.

• Please go to the bin directory and update all the existing links with the following commands (e.g. for RHEL 7):

  $> ln -sfn x86_64_RHEL_7/lmgrd lmgrd $> ln -sfn x86_64_RHEL_7/lmhostid lmhostid $> ln -sfn x86_64_RHEL_7/lmstat lmstat $> ln -sfn x86_64_RHEL_7/lmutil lmutil $> ln -sfn x86_64_RHEL_7/NXLMD NXLMD $> ln -sfn x86_64_RHEL_7/lmadmin lmadmin

Linking Libraries

The NanoXplore License Manager Daemon requires the library ld-lsb-x86-64.so.3 which might not be installed on Linux distributions.

• To do so, use the following command:

  $> ln -s /lib64/ld-linux-x86-64.so.2 /lib64/ld-lsb-x86-64.so.3

Retrieve Licensing Information

To retrieve the required license file from NanoXplore, you must provide the following information:

1. The Name of the Host where the License Manager Daemon is installed.

   • Use the following command to retrieve this information:

     $> hostname

2. The License Manager Host ID provided by the binary is located in /opt/NanoXplore/NXLMD/2.2/bin.

   • Use the following command to retrieve this:

     $> /opt/NanoXplore/NXLMD/2.2/bin/lmhostid

License File

• Once you retrieve the license file, copy it to the installation directory:

  $> cp license.lic /opt/NanoXplore/NXLMD/2.2/license.lic

Installation to Non-Default Directories

• You can install NXLMD in a non-default directory ${MY_INSTALLATION_DIRECTORY} using the following command:

  $> tar xzvf NXLMD-2.2-linux.tar.gz -C ${MY_INSTALLATION_DIRECTORY}

• Use the command below to change the path in the License File from
  ${MY_INSTALLATION_DIRECTORY}/NXLMD/2.2/license.lic
  to
  ${MY_BIN_DIRECTORY} = ${MY_INSTALLATION_DIRECTORY}/NXLMD/2.2/bin/

  $> DAEMON NXLMD ${MY_BIN_DIRECTORY}/NXLMD

Windows

In this document we refer to the directory where the NXLMD files are installed as the installation directory.

Archive

• Unzip the archive to the C:\NanoXplore directory

License File

• Copy the license file to the installation directory C:\NanoXplore\NXLMD\2.2\

Execution

Linux

Service Script

To do this, run the following command:

• Copy the lmadmin.service file to the /etc/systemd/system directory:

  $> cp /opt/NanoXplore/NXLMD/2.2/etc/lmadmin.service /etc/systemd/system/

• If you choose to use the default user specified in the lmadmin.service file, you must execute the following commands:

  $> useradd lmadmin $> chown -R lmadmin:lmadmin /opt/NanoXplore

Manual Execution

To manage the NanoXplore License Manager Daemon manually, use the following commands:

• Start

  $> systemctl start lmadmin

• Stop

  $> systemctl stop lmadmin

• Restart

  $> systemctl restart lmadmin

Automatic Execution

1. Use systemctl to add the new service:

   $> systemctl enable lmadmin

2. Start the NanoXplore License Manager Daemon with the following command:

   $> systemctl start lmadmin

• To print status information about the NanoXplore License Manager Daemon, use the command:

  $> systemctl status lmadmin

Terminate Process

• To stop the NanoXplore License Manager Daemon, use the command:

  $> systemctl stop lmadmin

Windows

Manual Execution

• Launch a Windows PowerShell and go to the installation directory of NXLMD:

  $> cd C:\NanoXplore\NXLMD\2.2\bin\lmadmin

• To launch the lmadmin service, use the following command:

  $> .\lmadmin.exe

Automatic Execution

1. Launch a Windows PowerShell as Administrator

2. Go to the NXLMD installation directory:

   $> cd C:\NanoXplore\NXLMD\2.2\bin\lmadmin

To add the lmadmin service to Windows:

• Run the following command:

  $> .\lmadmin.exe –installService lmadmin

Configuration of lmadmin

Once the lmadmin service is launched, you must configure it:

1. Open a navigator and access the following URL: http://127.0.0.1:8090 (if you launched the navigator on your server)
   You should obtain the following page:
   
   

   Open

   

   FlexNet Administration Page

2. Click on the “Administration” tab
   Note: You will be asked to sign in: the default Username and Password are “admin”/”admin”. Once logged in, you will be prompted to change the admin password

3. Click on the “Vendor Daemon Configuration” tab
   
   

   Open

   

   Vendor Daemon Configuration Page

4. You can now import your license file by clicking the “Import License” button.

Once imported, the license daemon should be automatically launched.

To check the status:

1. Navigate to the Dashboard tab

2. Click on the “Concurrent” button
   If the license daemon is well configured, you should obtain a page similar to this:

Open

If you encounter any issues, please contact NaxoXplore Support

Configuration of Variables

• When launching NanoXplore tools, the LM_LICENSE_FILE variable must be exported

• To avoid having to repeat this for every execution, you can to add it in the ~/.bashrc file with the following command:

  <port_number>@<machine_name>

  For instance:

  export LM_LICENSE_FILE=27000@localhost

Troubleshooting

LogFile Error

Linux

• If you use the nxlmd service, check the execution log file in the following directory :

  $> /var/log/NXLMD.log

• If you use the lmadmin service, check the execution log file in the following directory:

  $> /opt/NanoXplore/NXLMD/2.2/bin/lmadmin/logs/NXLMD.log

Windows

• Check the execution log files in:

  $> C:\NanoXplore\NXLMD\2.2\bin\lmadmin\logs

lmadmin Error (Linux)

Problem

The following message appears in the /opt/NanoXplore/NXLMD/2.2/bin/lmadmin/logs/web.log:

Possible Cause

You may have launched lmadmin as root.

Workaround/Fix

Try to launch lmadmin as another user (dedicated lmadmin for example)

lmhostid Error (Linux)

Problem

The following message appears in the execution log file (example):

Possible Cause

You probably have the wrong network interface (see previous sections for more information on how to change this)

Workaround/Fix

To check the hostid found by NXLMD without running the server, you can use the following command:

• You must get a full hostid with ${HOSTID} not empty:

  The FlexNet host ID of this machine is "${HOSTID}"

lmstat Error (Linux)

Check the NanoXplore License Manager Daemon is running correctly using the following command:

GLIBC Problem (Linux)

Problem

If the following error message appears:

Fix

Change the links in the ${MY_INSTALLATION_DIRECTORY}/NXLMD/2.2/bin directory to your OS version.

For example:

hostname Error(Linux)

Check your hostname is written in the file:

Firewall Problem

Linux

Resolution

If you have a firewall set, add a specific rule for the lmgrd Port (27000 by default) and for the NXLMD Port

• You can manually specify the NXLMD Port in the License File, for example, to set the port to 27010:

  $> DAEMON NXLMD ${MY_BIN_DIRECTORY}/NXLMD PORT=27010

Windows

If the Windows firewall is enabled, you must authorise lmadmin and lmgrd

• At the first launch of the server, Windows will ask you if you wish to authorise the services, otherwise, you must add them manually in the Firewall parameters.

“No such file or directory” Error (Linux)

Problem

If the following message appears when launching ‘journalctl –xe’ command:

Reason

The ld-lsb-x86-64.so.3 file may be missing.

Workaround/Fix

• Run the following command:

  $> ls -l /lib64/ld-lsb-x86-64*

• If there is no result, run the following command:

  $> sudo ln -s /lib64/ld-linux-x86-64.so.2 /lib64/ld-lsb-x86-64.so.3
