Server Startup Failures

If your server does not start when you executewebapps-start, it may be due to one or more of the following reasons.

License Manager

Your server will not start if you do not have a license manager running. For more information, check the logs listed inServer Logs.

To fix this issue, verify that you have a license manager running and that you have configured the license manager for use with the server usingwebapps-config.

SSL Configuration

Your server will not start if you do not have SSL configured correctly. For more information, seeEnable SSL.

Authentication Syntax

Your server will not start if thewebapps_authn.jsonfile is not syntactically correct. For more information, seeAuthentication.

以前安装

If you previously installed theMATLAB^®Web App Server™product but failed to runwebapps-uninstallfrom the system command-line before uninstalling the product from your system, your current installation of the server may not start.

Executingwebapps-uninstallunregisters services and removes user accounts used by the services. Failing to executewebapps-uninstallresults in orphan services and user accounts that cause your current installation of the server to not start.

To fix this issue, executewebapps-uninstallfrom thescriptfolder of your current installation before setting up your new server usingwebapps-setup.

Operating System	Default Location of Command-Line Scripts
Windows^®(Administrator)	`C:\Program Files\MATLAB\MATLAB Web App Server\R2022a\script`
Linux^®(sudo)	`/usr/local/MATLAB/MATLAB_Web_App_Server/R2022a/script`
macOS(sudo)	`/Applications/MATLAB/MATLAB_Web_App_Server/R2022a/script`

On Windows systems, you may also need to delete theUSRfolder located inC:\ProgramData\MathWorks\webapps\R2022abefore starting the new server.
