1)By default mysql does not support remote access...

2) you will have to specify this in the server first, (ofcourse you will not be able to do this from a remote machine!!! unless you have remote desktop access)

3)To enable access from a client machine called nile, do the following after starting mysqld (or mysqld_safe) on the server, named delaware:

% mysql -u root -p
mysql> use mysql;
mysql> grant all privileges on *.* to usrname1@'%'
identified by 'test' with grant option;
mysql> insert into host values('nile', '%', 'Y', 'Y', 'Y', 'Y', 'Y',
'Y', 'Y', 'Y', 'Y', 'Y', 'Y', 'Y');
mysql> exit

Hope this helps you!

The user name, usrname1, and the password, test, should be replaced by the real value.
One can then run mysql on nile as follows:

  % mysql --host=delaware --user=usrname1 -ptest

To restrict access to a user from a specific host, change '%' in the grant command to a valid hostname or ip address.

Identical to above...

To change the password(for root or any user)...

on Linux machine..

[ushastry@mmkserv test]#mysqladmin -uUserName -pOldPassword 'NewPassword'

///remote host is not allowed to connect to this mysql server

{From DOCS}
If the following error occurs when you try to connect from a host other than the one on which the MySQL server is running, it means that there is no row in the user table with a Host value that matches the client host:

Host ... is not allowed to connect to this MySQL server

You can fix this by setting up an account for the combination of client hostname and username that you are using when trying to connect.

If you do not know the IP number or hostname of the machine from which you are connecting, you should put a row with '%' as the Host column value in the user table. After trying to connect from the client machine, use a SELECT USER() query to see how you really did connect. (Then change the '%' in the user table row to the actual hostname that shows up in the log. Otherwise, your system is left insecure because it allows connections from any host for the given username.)

Login to MySQL Server(host on which MySQL Server is running)

[root@mmkserv test]# mysql -usqladmin -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 4 to server version: 4.0.20-log

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> GRANT ALL ON *.* TO 'EdwardPeter'@'%' IDENTIFIED BY '123';
Query OK, 0 rows affected (0.14 sec)

Query OK, 0 rows affected (0.16 sec)

mysql> \q

From windows machine...

If you are not sure how to configure, follow these steps:

1. Checking the mysql configuation; edit my.cnf

there a 2 different parameters depending on your mysql version

*for mysql < 4.1  (i think so) find the parameter    skip-networking    and comment it (#skip-networking)
*for mysql > 4.1  (i think so) find the parameter    bind-address        and comment it (#bind-adress)

also check the mysql listening port  (find parameter  port  and have a look which one is set)  normally it is set to 3306, we need that in 3.

restart mysql

2. Set mysql rights for an existing  user to get remote access rights. Login to mysql thorigh onsole as root and execute:

GRANT ALL PRIVILEGES ON mydatabase.* TO 'myuser'@'myclientip' IDENTIFIED BY 'mypassword';  

or create a new user with remote acces rights, with:

CREATE USER 'myuser'@'%' IDENTIFIED BY 'mypassword';
GRANT ALL ON *.* to myuser;

3. Firewall configuration
Normally it should work now, but if not:

If the client computer is behind a firewall or behind a router check if the needed mysql port (see point 1, normally 3306) is open to your client maschine.
If not try to pass the port through your router to your client maschine (better then open it for everyone, it depends on your purpose)
Also open the port at your client firewall.
For testing purpose it's always good to temporarly disable the client firewall (windows firewall or another product you use)

4. Now use whatever you want to connect, ODBC, PHP, your programm

MySQL ODBC Connector can be downloaded here:

this will give access to user monty with some_pass as thier password to access to mysql from a client like navicat or mysqlfront

the '@%' is a wildcard and therefore you dont have to specify your host ip here.
