Connecting to MySQL source database

Contents  Previous  Next

Problem:

Why cannot I connect to my local MySQL Server?

 

Solution:

There are several reasons why you cannot connect to the local database. If during the connection you get the error "Can't connect to MySQL server on 'localhost' (10061)", then probably MySQL server is installed incorrectly or the service (usually with the name "mysql") is not running. To check if the service is launched, open "Control Panel" -> "Administrative Tools" -> "Services" and find the MySQL service. If you cannot find this service, you should try to reinstall MySQL. In case you find it, run it with the Start button or use Start item in the context menu. If you get the error "Access denied for user 'root'@'localhost' (using password: YES)", then check if you enter the password for the root user correctly in case you change it during installation. If you installed MySQL with default values, you should use the user name root with the blank password and port 3306 to connect to the server.

Problem:

Why cannot I connect to a remote MySQL server?

 

Solution:

There could be several possible reasons that prevent you from successful connection to remote database. If the error message says "Can't connect to MySQL server on ‘some host' (10061)" then probably you should check the correctness of port and host name you've entered and also if the remote server is run. It often happens that the port through which the connection is set with MySQL server (normally, it's 3306) is closed for the security reasons by local firewall, corporate firewall or remote server firewall. The remote server port can also be closed by ISP, or TCP/IP protocol support is disabled on MySQL server. Please check this with your system administrator or ISP.
If the error message says "Access denied for user: root@somehost.somedomain" or "Host not allowed to connect to server", then the reason is that the user doesn't have permission to access the database.

 

 

Problem:

When I try to connect to a database, I get the following message: "Access denied for user: myuser@myhost.mydomain". Why does it happen?

 

Solution:

MySQL server uses client's login ('myuser' in your case) and the name of the host which it tries to set the connection from ('myhost.mydomain' in your case) for the client authentication. In your case the reason is that your 'myuser' user from the 'myhost.mydomain' host doesn't have permissions to access your MySQL server. It's quite possible that you successfully connected to your database with the same login and password in your PHP scripts or with the help of phpMyAdmin, but in this case MySQL server recognizes you as the 'myuser' user from the 'localhost' host who has the necessary permissions and allows you the access.
To solve this problem you should grant the necessary permissions to user myuser@ myhost.mydomain. You can do this with the help of phpMyAdmin or with the following SQL commands:

 

/*!50003 CREATE USER ‘myuser’@ ‘myhost.mydomain’*/;

GRANT ALL PRIVILEGES ON *.* TO ‘myuser’@ ‘myhost.mydomain’ IDENTIFIED BY 'user_password';

                       

Or, you can apply to your system administrator.

Problem:

I'm trying to connect to a remote MySQL database, but I receive only the "Host not allowed to connect to server" message. What can the reason be?

 

Solution:

This error occurs because you don't have a permission to connect to remote MySQL server from your host. Please contact your database administrator or, if you have access to MySQL server with grant privilege, you can use the GRANT statement to add a new user. For example, the following command will give full access from your host to the user:

 

/*!50003 CREATE USER 'user'@'user_host'*/;

GRANT ALL PRIVILEGES ON *.* TO 'user'@'user_host' IDENTIFIED BY ' user_password ';
