title: What does Mysql -u root mean?
body: <p>I have installed mysql in /usr/local/ directory. But when I try to use the server by typing mysql -u root it says '/usr/local/bin/mysql: No such file or directory'. I could understand that it looks in a different directory. But how to change it? Or should I have to install mysql in that directory? In which case, mysql installer does not allow me to change the directory as well. </p>
