How to change default path in pentaho-server 9.0.0.0.423?

Question

I need to change the default path to pentaho-server
Now: http://localhost:8080/pentaho

Should be like this: http://localhost:8080/pentahotest

I tried to change server.properties (pentaho-solutions/system/server.properties), but it isn't work

fully-qualified-server-url=http://localhost:8080/pentahotest/

I also tried to do it with nginx but nothing was successful
