Try to re-download and extract the server files again, and make sure the samp03svr is executable with chown +x

Show your server directory listing if still not works...

Code:

ls -l

If the server appear but not even going online (like it's crashed/closed), it should generate server_log.txt or crashinfo.txt file already atleast, check those file to see whats wrong...

Usually when i just install a new server, i often forgot to change the rcon_password in server.cfg, Other rare case is the download was corrupt.
