#1045 – Access denied for user ‘root’@'localhost’ (using password: NO)

Been using WAMP for several months now and once in awhile MySQL breaks. Somehow the user tables gets corrupted. To fix the problem instead of reinstalling the whole WAMP. Just replace the corrupted files. These 3 files are always corrupted.

user.MYI

user.MYD

user.frm

Download this mysqlusertables. Unzip the file, copy the 3 files inside.

Go into your C:\wamp\bin\mysql\mysql5.x.xx\data\mysql directory and paste, click yes to overwrite.

Restart All Service on your WAMP. Then you are good to go.

I’ll keep you posted soon on why these tables easily gets corrupted.

*Update*

Digging deeper to the culprit I found out the tables for users in the mysql db has warnings, meaning they are corrupt. So to avoid doing the steps above while your MySQL and phpMyAdmin is still working. Go to phpMyAdmin, access mysql db, then select users table then click on operations then under “Table maintenance” click on Repair Table. Viola!!!

No Renaming Tables feature in phpMyAdmin

Quick tip. The feature is not (yet) supported in phpMyAdmin but you can easily make the change by simply issuing this sql statement. RENAME TABLE old_table TO new_table Related posts:Import sql dump using the MySQL client Related posts:

Import sql dump using the MySQL client

lopau — Thu, 07 May 2009 15:38:25 +0000

This is useful if you don’t have access to phpmyadmin on your server but have access to ssh and ftp. Or you have a huge sql dump like 10MB or higher that you cannot import directly on phpmyadmin. In my case the phpmyadmin directory was password protected by Apache and I don’t have the right password.

First upload the .sql file on your server using an FTP client and remember the path.

eg.
For Linux
/home/lopau/mydump.sql

for Windows
C:/wamp/www/lopau/mydump.sql

On the command line access MySQL
$> mysql -u username -p password

replace username and password with yours.

On the MySQL client command line access and use your database.
$> use lopaudb;

Now to import your dump;
$> source /home/lopau/mydump.sql;

If successful you should see
Query OK, 13 rows affected (0.00 sec)

That easy.

I miss using a Mac, saving up to get the latest MacBook Pro.

Here is quick tip for an alternative method on how to restart Apache using the Terminal. Long method is go to Preferences then Sharing and disable enable Personal Web Sharing.

Open the Mac OS X Terminal window then type in.

All in One Package

I didn’t like using All in One Package during the my early years of learning how to install Apache, PHP and MySQL in my Windows box – there were programs like PHPTriad and similar which offers these three in one convenient installation without getting your hands dirty so to speak on the configuration. From my experience you should start with the manual installation to know the ins and out. That was what I was doing for the years, when a new version comes out I apply the upgrade to my system.

Earlier this month I got this client who uses WAMP 2.0 setup for the system we were developing. Somehow I wasted several hours trying to make it run on my system. Was getting close but somehow if some changes were done to the system codes I feel it would break again. So I decided to try using WAMP 2.0 and it turns out its not that bad afterall. It has a UI for disabling/enabling extensions and modules, you can still go into the php.ini, my.ini, httpd.conf if you decide to edit manually from a shortcut all in one convenient place in your systray.

It made my work faster, overall if you are using the manual way and move to an all in one package like WAMP 2.0 you would benefit both time and organization. I’m now a believer.
