                       what I have done

1.bring up a command line window and follow your advice step by step(see "mysql command line" and "mysql command line2" pictures)
and I am sure "the username is lams2, the database name is lams2 and the password is lamsdemo".

2.uninstalled the lams2.0 completely.

3.installed the lams2.0 to make sure mysql "the username is lams2, the database name is lams2 and the password is lamsdemo"

4.start up the lamsv2.It took a long time and failed like before.

5.start up again,but there was a error(see "start up error " picture).
