@Phil's Answer and @Mr.Brownstone's Answer should suffice for your question, so +1 for both of them.
For the following, let's assume you are logging in with username myuser
Once you have connected to mysql, you should run the following query:
SELECT USER(),CURRENT_USER();
- USER() reports how you attempted to authenticate in MySQL
- CURRENT_USER() reports how you were allowed to authenticate in MySQL
Sometimes, they are different. This may give you insight into why you are allowed to login to mysql.
Here is another query you need to run:
SELECT CONCAT('''',user,'''@''',host,'''') dbuser,password
FROM mysql.user WHERE user='myuser';
This will show you the ways in which you are allowed to login as myuser.
If you see 'myuser'@'localhost', then you can authenticate from within the DB Server.
If you see 'myuser'@'127.0.0.1' and do not see 'myuser'@'localhost', then you can authenticate from within the DB Server again but you must specify the --protocol=tcp from the command line.
If you see 'myuser'@'%', then you can do remote logins from any server.
If you see 'myuse'r@'10.20.30,%', then you can do remote logins only the from 10.20.30.% netblock.
Once you see what 'mysql.user' has for your user, you may want to allow or restrict myuser from logggin in one way and not the other.
If you simply want to check if the password for myuser is whateverpassword, you can do the following:
SELECT COUNT(1) Password_is_OK FROM mysql.user
WHERE user='myuser'
AND password=PASSWORD('whateverpassword');
You can check from the command line as follows:
PASSWORDISOK=`mysql -uroot -p... -ANe"SELECT COUNT(1) Password_is_OK FROM mysql.user WHERE user='myuser' AND password=PASSWORD('whateverpassword')"`
If you are not root and want to test myuser only, you can do this:
PASSWORDISOK=`mysqladmin -umyuser -pwhateverpassword ping | grep -c "mysqld is alive"`
If you get 1, password for myuser is verified as good.
