Bug #3014	Error 2003 - can't connect to MYSQL server on localhost <10061>

Status:	Can't repeat	Impact on me:	None
Category:	MySQL Server: InnoDB storage engine	Severity:	S2 (Serious)
Version:	4.0.16-max-debug	OS:	Windows (WINDOWS 2000 Pro)
Assigned to:		CPU Architecture:	Any

Description:
Juging from the 'expert' websites this is a very big problem for it keeps popping up over and over again. Appearantly, Windows is blocking access so the MYSQL server doesn't connect to localhost or connect at all. This so called 'expert' advice I have been getting has been way off base cause they keep dishing out the same old advice which doesn't work. Fortunatly this MYSQL version has the debuging feature with it so I can present the precise problem to you.

040226 18:19:18 InnoDB: Operating system error number 5 in a file operation.
InnoDB: See http://www.innodb.com/ibman.html for installation help.
InnoDB: The error means mysqld does not have the access rights to
InnoDB: the directory. It may also be you have created a subdirectory
InnoDB: of the same name as a data file.
InnoDB: File name .\ibdata1
InnoDB: File operation call: 'open'.
InnoDB: Cannot continue operation.

See What I mean? The InnoDB people would like us to pay an obnoxious sum to fix it. It's not going to happen.

How to repeat:
Error 2003 - Can't connect to MYSQL server on 'localhost' <10061>

Error log message below:

Suggested fix:
Bypass Bill Gates attempts to block access to whatever directory he is blocking access to. Find a way into whatever directory WINDOWS is keeping the InnoDB from accessing. The InnoDB people seems to know something about this. They are trying to collect obnoxious sums for the previledge of having whatever roadblock removed from whatever directory Microsoft is blocking access to. I would definitely advise you to investigate and to look into the matter. It's a rather widespread problem and the 'expert' advice that people have been seeking has proven to be way off the mark as the enclosed bug report seems to indicate.

There is not enough information provided in order to identify the cause.  As it sounds like a configuration issue, you should detail where you have installed MySQL and provide your my.ini.

No feedback was provided. The bug is being suspended because
we assume that you are no longer experiencing the problem.
If this is not the case and you are able to provide the
information that was requested earlier, please do so and

Hi,

I have installed the MySQL server 5.0 in Windows XP Professional with the essential installer. While configuring MySQL Server Instance with the MySQL Server Instance Configuration Wizard, I am repeatedly getting "The security settings could not be applied. Error Number 2003. Can't connect to MYSQL server on 'localhost' (10061)". I have the McAfee Personal Firewall Plus running in my machine and opened the port 3306 for MySQL. I tried repeatedly by removing the Server Instance and then reconfiguring, but everytime I am getting the same error. Please help.

Here is my .err file.

If you're like me, your running ASP & PHP to a MySQL database, on top of IIS... from a Windows 2000 server. PHP will connect to MySQL, but ASP won't. It's an issue with the firewall and you have to manually change a firewall setting. I use ZoneAlarm Pro. So here is how to change it 1st for non-Zone Alarm firewalls and 2nd for Zone Alarm firewalls.

Non-Zone Alarm firewalls:
Check your options for the "COM Surrogate" setting. Give it some kind of "trusted access" rights. It's the c:\%winroot%\system32\dllhost.exe file.

Zone Alarm Pro firewall:
Look in Program Control (left side), then the Programs tab (top middle). Find "COM Surrogate". The "Access:Trusted" setting is the one that will block IIS' attempt to connect to MYSQL. Enable it and you can get around the "can't connect to MYSQL server on localhost <10061>" problem. Simply switch the settings as follows.

COM Surrogate - SmartDefense - Custom
COM Surrogate - Trust Level - ASK (blue "?" mark)
COM Surrogate - Access:Trusted - ALLOW (green check mark)
COM Surrogate - Access:Internet - ASK (blue "?" mark)
COM Surrogate - Server:Trusted - ASK (blue "?" mark)
COM Surrogate - Server:Internet - ASK (blue "?" mark)
COM Surrogate - Send Mail - ASK (blue "?" mark)

Key:
The Zone Alarm firewall has these 3 options for each ALLOW/BLOCK/ASK option:
ALLOW = (green check mark)
BLOCK = (red letter "X")
ASK = (blue "?" mark)

Notes: For our purposes, the only setting that matters is the one with the "ALLOW (green check mark)" setting for "Access:Trusted". You can probably do whatever you want with the other settings.

Here is what the categories mean:
"Access:Trusted" will only let the dllhost.exe file use the rest of your computer. It won't access the Internet like the "Access:Internet" setting would. It won't run as a local server, that only your PC can use, like "Server:Trusted" would. It won't run as an Internet server, that everyone else in the world can use, like "Server:Internet" would. So you're safe with switching the setting above to the "ALLOW" option.

Enjoy!

Hi,

I had the same error 5...
this was after a restore of the ibdata1.
after playing wit access rights, folder names etc, I found that the 'read-only'flag was set (Windows machine) on the ibdata and the logfiles..
Disabling read-only solved my problem

Hi,
When you remove the instance, make sure that, at the same time you remove Mysql client (e.g. MysqlYog) from your system. Then try again to configure the server.

This problem occurs because client blocks the port.

I was having the same problem. I tinkered around after finding no help from forums.

Go to <c>:\<mysql_install_dir>\bin 
and make sure you have mysql.exe running.

I also read something about installing Mysql as a windows service, but this solution seems a lot less troubling and it fixed my problems.

1. Signout skype and
2. Start wamp server and now try it should be ok......

Could you please try with new release version 5.5 at least. Thanks.

I am running into the same problem.  I have Windows 7 Home Premium.

I couldn't repeat with new server version 5.5/5.6/5.7.
