I use the root account created the account 'a'@'%'. But I can't use the account to connect to MySQL server when I specify the host parameter. I can successfully connect without the -h parameter. Please see the transcript below.
I hope someone can help me to explain it. Here is a quick-and-dirty method for checking out how MySQL performs successful authentication. Please run this query: SELECT USER(),CURRENT_USER(); reports how you attempted to authenticate in mysqld reports how you were allowed to authenticate by mysqld Sometimes, USER() and CURRENT_USER() are different. That's because mysql authentication follows a specfic protocol. According to pages 486,487 state the following on mysql's authentication algorithm: There are two stages of client access control: In the first stage, a client attempts to connect and the server either accepts or rejects the connection. For the attempt to succeed, some entry in the user table must match the host from which the client connects, the username, and the password. In the second stage (which occurs only if a client has already connected sucessfully), the server checks every query it receives from the client to see whether the client has sufficient privileges to execute it.

However, it's possible for more than one record to match: Host values in grant tables may be specified as patterns contains wildcard values. If a grant table contains entries from myhost.example.com,%.example.com,%.com, and%, all of them match a client who connects from myhost.example.com. Patterns are not allowed for the User values in grant table entries, but a username may be given as an empty string to specify an anonymous user. The empty string matches any username and thus effectively acts as a wildcard.

It does this by sorting records with the most specific Host and User column values first, and choosing the matching record that occurs first in the sorted list, Sorting take place as follows: In the Host Column, literal values such as localhost, 127.0.0.1, and myhost.example.com sort ahead of values such as%.example.com that have pattern characters in them. Pattern values are sorted according to how specific they are. For example,%.example.com is more specific than%.com, which is more specific than%. In the User column, non-blank usernames sort ahead of blank usernames. That is, non-anonymous users sort ahead of anonymous users.
