Will re-installing phpmyadmin will have any effect on my Databases?

I am quiete new and somehow I crashed my phpmyadmin website, it can't be
displayed without errors after changing the port of it once. So does it
has any effect on my databases when I reinstall my phpmyadmin ? I guess it
will not change anything since it doesn't come with mySQL together, but I
want to be sure. So :
Can I simply uninstall and re-install without loosing any data from mySQL
databases?
I use an Ubuntu 12.04 server, thx in advance! if you need more
information...letme know.
