you haven't set the root password yet the password will be blank;
so ;
you should just press enter here;
Enter current password for root (enter for none)<–初次运行直接回车;
OK successfully used ;
password moving on;
Setting the root password ensures that nobody can log ;

By default a ;
MySQL installation has an anonymous user allowing anyone;

go a bit smoother. You should ;
remove them before moving into a;
production environment;
