Choosing the Flexnet server manager:

There are three types of the FlexNet server managers.

 We recommend using lmadmin.

Prerequisites

• You have the license owner account credentials.

• If your operating system is Windows:

  To use lmadmin on Windows platforms, the Microsoft Visual C++ 2008 Redistributable Package (x86) must be

  installed. You have an option to install this package during the FlexNet Publisher License Server Installer process.

  • You can run lmadmin (11.12.1) on officially supported platforms:

  • • Windows 8

    • Windows Server 2012

    • Windows Server 2008
    • Windows 7 (Ultimate)

    • Windows Vista (Ultimate)

  • You can run lmadmin (11.14) on officially supported platforms:

    • Windows 10

    • Windows Server 2008, including SP1, SP2, and R2

    • Windows 8
    • Windows 8.1
    • Windows 7, including SP1
    • Windows Server 2012 R2
    • Windows Server 2012
      
      
• If your operating system is Linux:
  • For 32bit systems it is recommended to use 32bit lmadmin or 32 bit lmgrd
  • For 64 bit multi-arch systems it is recommended to use 32bit lmadmin and 64bit lmgrd
  • You have to have glibc libraries installed corresponding to your operating system architecture.

  • You have to create a non-root system user with root privileges and install/run the server tools using it:
    
    

    This can be achieved either by:

    1. Adding the user to the 'sudo' group

    2. Editing the file /etc/sudoers using visudo.

    Method 1 (Ubuntu based):

    Method 2 (Ubuntu based):

    
    

    Method 1 (Redhat/Fedora/CentOS)

  • If your operating system is 32 bit Linux:
    
    • It is recommended to use 32 bit lmadmin installer, or 32 bit lmgrd

    • You have to install the Linux Standard Base (LSB) library.

      For Ubuntu:

      For Redhat/CentOS/Fedora:

  • If your operating system is 64 bit Linux:

    • For version 11.12.1 we recommend either using the 32 bit lmadmin installer(for multi-arch systems), or the 64bit lmgrd.

      Installing 32 bit lmadmin on a multi-arch machine will require the 32bit libraries.

      For recent Ubuntu:

      For older Ubuntu use:

      
      

      For Redhat/CentOS/Fedora:

      
      

      Running 64bit lmgrd on 64 bit systems requires 64 bit Linux Standard Base (LSB) library.

      For Ubuntu:

      For Redhat/CentOS/Fedora:

    • For version 11.14 we recommend either using the 32 bit lmadmin installer, or the 32bit lmgrd for multi-arch systems. 64 bit 11.14 lmadmin/lmgrd binaries are not available.

      Both of them require 32 bit librarires. Install it using:

      For recent Ubuntu:

      For older Ubuntu:

      For Redhat/CentOS/Fedora:

      
      

      lmadmin 11.14 comes with libssl.so.1.0.0 in its installation directory.
      You need to add these libraries in lmadmin directory to the LD_LIBRARY_PATH in order to run lmadmin.
      
      e.g. if your lmadmin installation is at /opt/FNPLicenseServerManager then adding it to the path would look like this:

  Check if LSB was installed successfully using:

Procedure

For Windows

1. Download the FlexNet server installer from our website.

   Log in with license owner credentials, if prompted.

2. Install the server manager.

   We highly recommend running the FlexNet license server (lmadmin) as a service (on Windows).

   As a result, the server can start automatically after the machine boots. Starting the server manually is not user-friendly – there is no GUI for this action.

   If your operating system is Windows, you only need to select the Run as a service check box when prompted during the lmadmin installation.

   Selecting to run the FlexNet license server as a Windows service

   For the instructions on how to create a daemon, refer to Automatic Start in License Administration Guide.

3. Download the Basic concepts - Cameo from our website.
4. Place the Vendor daemon into the FlexNet server installation folder. If you use lmadmin, do the following:
   
   

   1. Open the FlexNet server installation folder.

   2. In the open folder, create the licenses\cameo folder.

   3. Place the Vendor daemon in <FlexNet server installation folder>\licenses\cameo.
      
      Placing the Vendor daemon Cameo to the FlexNet installation folder

      Note that all files in FNPLicenseServerManager must have read/write permissions. lmadmin or cameo daemon may not start even if a log file or cameo daemon does not have r/w permissions.

      Use this command to set permissions for all files within the directory recursively.

      chmod -R 755 FNPLicenseServerManager

5. Start the server by running the lmadmin file from the FlexNet server installation directory.

For Linux

1. Download the FlexNet server installer from our website.

   Log in with license owner credentials, if prompted.

2. Install the server manager.

   We highly recommend running the FlexNet license server (lmadmin) as a daemon (on OS X or Linux).

   As a result, the server can start automatically after the machine boots. Starting the server manually is not user-friendly – there is no GUI for this action.

   For the instructions on how to create a daemon, refer to Automatic Start in License Administration Guide.

3. Download the Basic concepts - Cameo from our website.
4. Place the Vendor daemon into the FlexNet server installation folder. If you use lmadmin, do the following:
   

   1. Open the FlexNet server installation folder.

      For OS X and Linux users

      If you don't have permission to open the FlexNet server installation folder, execute the following command from the root:

      • On OS X
        

        chmod g+x FNPLicenseServerManager/
        chmod –R g+w ./*

      
      

      • On Linux

        chmod g+x FNPLicenseServerManager/

      
      

      
      

   2. In the open folder, create the licenses\cameo folder.

   3. Place the Vendor daemon in <FlexNet server installation folder>\licenses\cameo.

      
      

5. Start the server by running the lmadmin file from the FlexNet server installation directory.

If you come across any issues while installing/running the software, please refer to the Troubleshooting section.

Other useful commands:

• Find out the shared object dependencies in Linux. The result can show what files are missing libraries to run that file.

• File information in Linux

• Launching lmgrd manually via command line. lmgrd, cameo and license file must be in the same directory:

   license_file_name - the path to the license file. Can use only the license file name if all files are in the same directory.

   logfile_name - the path to the log file. Can use only the license file name if all files are in the same directory. Make sure the files have read/write privileges.

• Checking server status:

server_port - the port the server is operating on (Not the cameo daemon port)

server_host_or_ip_address - the host/address the server is hosted on

Troubleshooting

JRE libraries are missing or not compatible

Error message while installing 32bit lmadmin on 64bit multi-arch Linux system.

The error message is misleading, the solution to fix it, is to install the 32bit libraries.

In Redhat/CentOS/Fedora:

In recent Ubuntu use:

In older Ubuntu use:

No such file or directory running lmadmin

That may mean that you are missing the correct Linux Standard Base (LSB) library.

Also it may mean that you are using a 64bit executable in a 32bit system and vice versa.

Install the Linux Standard Base (LSB) libraries to fix it.

libssl.so.1.0.0 library required running lmadmin

lmadmin 11.14 comes with libssl.so.1.0.0 in its installation directory.
You need to add these libraries in lmadmin directory to the LD_LIBRARY_PATH.

e.g. if your lmadmin installation is at /opt/FNPLicenseServerManager then adding it to the path would look like this:

lmadmin won't start

If you install lmadmin on a Linux-based system when logged on as root, you may encounter various issues. For example:

•  When you try to launch the Web server (http://localhost:port) on the license server, you encounter an "Unable to connect" error.
•  When you attempt to run the license server, you may encounter the following errors:

 
    In Web.log:

•  A process listing for lmadmin ('ps aux | grep lmadmin') returns no results.
•  A process listing for cameo ('ps aux|grep cameo') returns results if run right after lmadmin is started but then fails after a few seconds. If you view the cameo.log file in the logs directory (the default location is /opt/FNPLicenseServerManager/logs), you see that the process failed with the following error messages:

Therefore, when you are installing lmadmin on a Linux-based system, it is recommended that you avoid installing as root. If you have already installed lmadmin when logged on as root and you do not want to reinstall lmadmin, change the ownership of all of the files in the installed folder from root to another user

'Can't make directory' error running lmgrd

Can't make directory /usr/tmp/.flexlm, errno: 2(No such file or directory).

This means that directory /usr/tmp used by lmgrd is missing on your system(usually on Ubuntu systems). This error does not impact license checkout.

The solution to fix it is to create a symbolic link /usr/tmp pointing to /tmp:

You have no permission to install lmadmin in that directory

Make sure the lmadmin installer has read/write access.

or

to give read/write privileges to all files within a folder.

Then run lmadmin using sudo:
