I've installed the latest version of xampp and started the xampp console and tried to run phpadmin module. It was unable to connect using the root and default password (which is blank). I tried to connect to mysql using the HeidiSQL too. Still it was not connecting using the username root and no password. Seems the default password of root is set to something in the latest versions of xampp(may be I'm wrong). Can someone help me with this?

A. Does MySQL show as started in the Conrol Panel?

B. The exact error codes, and the contents of the C:\xampp\mysql\data\mysql_error.log would be useful.

C. XAMMP (and all other direct MySQL installers) ship with 'root' password set to null (the empty set). However, there are configuration options for some MySQL tools that will not work at all with a null password.

D. In the \xampp\mysql folder there is a eponymous batch file that resets the root and pma passwords to a null. Its called - resetroot.bat

Good Luck

MySQL is showing as started.
The message that I'm getting in HeidiSQL is "SQL Error (1045): Access denied for user 'root'@'localhost' (using password : NO)"

The following is the dump from the log

A. Can you access phpMyAdmin via the XAMPP Welcome page at this time?

B. I don't know HeidiSQL, but I do have an idea what the issue 'might' be. IF you are able to access phpMyAdmin via localhost, HeidiSQL might be trying to make a TCP/IP connect rather than a local socket connection.

C. You might try binding to 127.0.0.1 in your my.ini or my.cnf

Good Luck

The bindaddress was commented out. I uncommented it and it now looks as bind-address="127.0.0.1"
Restarted MySQL.
But the problem still persists.

2 questions and a suggestion:

did you reset your 'root' PW as I have suggested?

In a command window, ping localhost and see what it resolves to.

it it only resolves to " ::1 "

try adding a line like this to your hosts file

127.0.0.1 localhost

I'm betting that its a PW issue -

Good Luck

Pinging the local host is resolving to MyName-Laptop.DomainName.com
I've just installed the XAMPP and was trying to access. Not sure how the password might change(as per the heidisql link that you posted).
Is there anyway that the default MySQL installation from xampp has any other password other than blank string?

But for changing the password, we should login right?
How did you manage to login to MySQL for changing the password?

My issue got resolved. When I was starting MySQL using xampp control, it was actually starting another MySQL server that was already installed in the Program Files.
I tried starting the MySQL using the batch file provided in the xampp directory. It started and I was able to connect. I deleted the one in the Program files. But still the xampp control is trying to start it from the wrong location. Can you plz suggest me how to resolve this one?

Hi allabakash,

Your other MySQL instance has registered a Windows Service to start it. If such a service exists XAMPP can't distinguish if this is his own instance or not, and tries to start it.

To solve that issue unregister the MySQL Service. You can simply do that in your Windows cmd (with enhanced administration priviledges)

Code: Select all

sc delete "mysql"
