To start MATLAB® software on a client computer, the license manager must be running on the server. On Windows systems, the installer configures the license manager to start automatically when you start your system. (On Linux systems you must edit the system boot scripts–see Configure the License Manager to Start Automatically on Linux Systems.) If you accepted this default configuration, the easiest way to start the license manager is to restart the computer on which you installed the license manager. There are several other ways to start the license manager, depending on your platform. The following section describes these methods.
The user name associated with the license manager process should be a user that is defined locally on the system, not defined on a network. The license manager starts up properly only if the user name can be found during the startup process on the computer, before network users are available.
You can start the license manager on Windows systems using any of the following methods:
Use the Windows Services control panel to start or stop the license manager, if you chose to configure it as a service during installation. On the Windows Start menu, select Settings > Control Panel > Administrative Tools > Services
Use the license management utility, lmtools.exe,
included in your MATLAB installation in the matlabroot\etc\$ARCH$ARCH is a platform-specific subfolder.
Start the lmtools.exe application and select the Start/Stop/Reread tab.
To start the license manager
daemons on a Linux or Mac OS X system, execute the lmstart script
(located in the matlabroot/etcmatlabroot represents the name of
your top-level MATLAB installation folder. The lmstart script
stops any currently running daemons and starts new ones.
To run lmstart on a Mac OS X system, open
a terminal window using the Terminal application
(found in /Applications/Utilities)
and navigate to the /etc folder in your MATLAB installation
folder:
cd /Applications/MATLAB_R2016b.app/etc
A user other than root should run the lmstart script
because it is a security risk to run any program as root that does
not require root permissions. The license manager (lmgrd)
does not require root permissions. If you must start the license manager
as root, use the su command to start lmgrd as
a nonprivileged user:
su username -c "lmgrd -c license_file -l /var/tmp/LM_TMW.log"
username is a nonprivileged
user. To configure the license manager to start automatically at boot time on Linux® systems, use the standard method for starting services automatically on your Linux distribution.
Start the Flexnet service with the
-u
username option, where
username represents a valid user name other than
root. For security reasons, superuser cannot be an owner of the license manager
daemons.
Make sure that the license manager starts at the very end of the system boot sequence. For the license manager to start correctly, the network must already be running. Use whatever mechanism your version of Linux provides to configure the boot sequence.
