Introduction

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

Although it should work correctly on any recent 64 bits Linux and Windows operating system, 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 NanoXplore team at support@nanoxplore.com.

Please note that you should launch some of the described Linux commands as root, adding “sudo” in front of each command.

Package description

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

NXLMD root directory
- 2.2 current version
  - bin contains binary files
  - etc contains one service file to automate daemon execution (only on Linux)

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

NXLMD root directory

Installation

Linux

In this document we refer to the directory where the NXLMD files are installed as the installation directory. The default / recommended directory is /opt/NanoXplore.

Linux distribution adaptation

The NanoXplore License Manager Daemon supports several Linux distributions. You have to point to the correct one in 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 needs the library ld-lsb-x86-64.so.3 which might not be installed on Linux distribs. The following command must be done:

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

Retrieve information for licensing

To get the needed license file from NanoXplore, the customer provides two pieces of information:

the name of the host where the License Manager Daemon is installed, use the following command:

$> hostname

the License Manager Host ID provided by the binary located in /opt/NanoXplore/NXLMD/2.2/bin, use the following command:

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

License file

Once you get the license file it has to be copied in the installation directory:

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

Install in a non-default directory

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}

You also have to change the path in the license file:

${MY_INSTALLATION_DIRECTORY}/NXLMD/2.2/license.lic

$> DAEMON NXLMD ${MY_BIN_DIRECTORY}/NXLMD

with ${MY_BIN_DIRECTORY} = ${MY_INSTALLATION_DIRECTORY}/NXLMD/2.2/bin/.

Windows

In this document we refer to the directory where the NXLMD files are installed as the installation directory. The default / recommended directory is C:\NanoXplore.

License file

The license file has to be copied in the installation directory C:\NanoXplore\NXLMD\2.2\.

Execution

Linux

Service script

Running the NanoXplore License Manager Daemon as a service requires the installation of the provided lmadmin service.

Simply copy the lmadmin.service file to /etc/systemd/system directory:

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

Please make sure that the user and group specified in lmadmin.service file exists.

Please make sure that the user has writing rights in /opt/NanoXplore/NXLMD.

Note

The user and group cannot be ‘root’. Use instead a specific user like ‘lmadmin’ for example.

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

$> useradd lmadmin

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

Manual execution

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

start

$> systemctl start lmadmin

stop

$> systemctl stop lmadmin

restart

$> systemctl restart lmadmin

Automatic execution

Use systemctl to add the new service:

$> systemctl enable lmadmin

Then 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

Execution log files are available in /opt/NanoXplore/NXLMD/ directory.

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

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

$> 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 lmadmin service is launched, you have to configure it.

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.

Click on the “Administration” tab. You will be asked to sign in. The default user name and password are “admin” / ”admin”.

Once logged in, you will be prompted to change the admin password.

Next, click on the “Vendor Daemon Configuration” tab.

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, go back to the “Dashboard” tab and click on the “Concurrent” button. If the license daemon is well configured, you should obtain a page similar to:

Troubleshooting

LogFile

Linux

You can check the execution log file in the following directory if you use the service nxlmd:

$> /var/log/NXLMD.log

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

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

Windows

You can check the execution log files in:

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

lmadmin (Linux)

If you have the following message in the /opt/NanoXplore/NXLMD/2.2/bin/lmadmin/logs/web.log:

[alert] getpwuid: couldn't determine user name from uid 4294967295

You probably have launched lmadmin as root.

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

Be sure that this user is the owner of the /opt/NanoXplore/NXLMD directory.

lmhostid (Linux)

If you have the following message in the execution log file (for example):

Wrong hostid on SERVER line for license file:

${MY_LICENSE_FILE}

SERVER lines says 08002780463d, hostid is (Can't get hostid of type 2 [])

Invalid hostid on SERVER line

with ${MY_LICENSE_FILE} = ${MY_INSTALLATION_DIRECTORY}/NXLMD/2.2/license.lic

You have probably the wrong network interface. To change it, see previous sections.

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

$> ${MY_INSTALLATION_DIRECTORY}/NXLMD/2.2/bin/lmhostid

You have to get a full hostid with ${HOSTID} not empty:

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

lmstat (Linux)

You can check that NanoXplore License Manager Daemon runs correctly using the following command:

$> ${MY_INSTALLATION_DIRECTORY}/NXLMD/2.2/bin/lmstat -a

GLIBC problem (Linux)

If you have the following error message:

NXLMD: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by NXLMD)

You have to change the links in directory ${MY_INSTALLATION_DIRECTORY}/NXLMD/2.2/bin to your OS version. For example:

lmgrd -> x86_64_UBUNTU_18/lmgrd

lmhostid -> x86_64_UBUNTU_18/lmhostid

lmstat -> x86_64_UBUNTU_18/lmstat

lmutil -> x86_64_UBUNTU_18/lmutil

NXLMD -> x86_64_UBUNTU_18/NXLMD

hostname problem (Linux)

You can check that you have your hostname written in the file /etc/hosts.

Firewall problem

Linux

If you have a firewall set, you must add a specific rule for lmgrd port (default is 27000) and for NXLMD port.

You can manually specify the NXLMD port in license file. For example, to set the port 27010:

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

with ${MY_BIN_DIRECTORY} = ${MY_INSTALLATION_DIRECTORY}/NXLMD/2.2/bin/

Do not forget to add a rule for this port too.

Windows

If the Windows firewall is enabled, you have to authorize lmadmin and lmgrd. On the first launch of the server, Windows will ask you if you want to authorize the service. Otherwise, you can manually add them in the firewall parameters.

No such file or directory (Linux)

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

$> lmadmin.service: Failed at step EXEC spawning /opt/NanoXplore/NXLMD/2.2/bin/lmadmin/lmadmin: No such file or directory

The ld-lsb-x86-64.so.3 file is probably missing. Run the following command to check it:

$> 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
