Can't connect to MySQL server on 'localhost' (10061) after Installation

Question

I installed MySQL using mysql-installer-5.5.20.0.msi on Windows 7. From the cmd window, I run \"mysqlshow -u root -p\". It asked for a password, then return

Answer 1

I solved this by adding the following arguments to the command line string:

mysql --user username --password password --host localhost --port 3306 databasename < "system path to .sql file"

Without the --host and --port arguments, especially if you change the port to let's say 3307, which is a non default value, will cause this error.
