After installing the FlexNet for Linux license server, an error is reported when lmgrd is executed

question:

After installing the FlexNet Publisher Binaries for Linux license server, when trying to start the FlexNet License daemon lmgrd on the Linux server, the program will abort and print the following error message: required file not found  

bash: ./lmgrd : cannot execute: required file not found

或者  No such file or directory

lmgrd: No such file or directory

What does this mean and what needs to be done to get lmgrd to work?

reason:

One possible cause is missing Linux Standard Base (LSB) components required by lmgrd. To check, you can execute the following command:

$ ldd lmgrd
