Can't connect to MySQL server on localhost (10061) on window 7

问题

I am having window 7 as a operating system in the production machine where i am trying to use MySQL server 5.0 as a database. But i am unable to configure MySQL on my production machine. Following is the error i am receiving.

The security setting could not be applied to the database because the connection has failed with the following error:

Error no. 2003
Can't connect to MySQL server on localhost (10061).

The message also prompts that you need to open TCP 3306 port to resolve this issue, i checked it and found that TCP 3306 port is already opened and state is listening.

This is my 'netstat -an' command result -

Proto   LocalAddress   ForeignAddress   State
TCP     0.0.0.0:3306      0.0.0.0:0           LISTENING

It means TCP at 3306 is open. Can anyone please tell me the solution of this problem. However i am able to install and configure the same MySQL Server setup in window xp. I tried google as well and found a lot of blogs but none is of use.

Thanks a lot.

Change

 host: localhost

to

 host: 127.0.0.1

This is likely caused by the way your database is being resolved.

回答2:

have you checked whether the port 3036 is already in use by another application? Have you checked whether a telnet hostname 3036 works on the local MySQL server and also on the remote machine?

回答3:

First check in the system, MySQL services is in running condition or not. look out on path of services go to right click on My Computer > manage > Services and Application > Services and check MySQL service status is started or not. Otherwise right click on service and start to service.

I hope this will help you.

I didn't find the MySQL services even after solving the problem.
I just run the mysqld as administrator and the problem is solved. So, simple but It took me 3 hours to find the solution.

回答5:

The problem was rsolved. The MySQL was not running in the Services section of Settings. Because XAMMP had disconnected the already running application in the background.
