I´m replying to myself :)
I have never worked with Linux, so I search little bit and found this video: https://www.youtube.com/watch?v=T20jXu7rDCA
Based on it, I understood how to solve my problem.
I have edited evok.conf by nano text editor, where it is necessary to deleted all " ; " around [Extension 1]
Than:Ctrl o, Enter, Ctrl x reboot
After reboot , Evok and Modbus started correctly.
