解決MySQL安裝時1045錯誤的方法

該錯誤只在Windows系統(tǒng)上出現(xiàn)，Linux下好像好沒有，據(jù)說這個錯誤已經(jīng)存在n年了，有人extremely dispointed that it still exists here in 2009!

錯誤的原因更令人抓狂，那就是mysql server instance config wizard根本沒有為你設(shè)密碼，于是root密碼是空！實在不明白如果沒有為我設(shè)密碼那中間為什么叫我設(shè)個密碼。

解決辦法：

I clicked Skip on the dialog that states the Error 1045...
Then cancelled the "MySQL Server Instance Config Wizard"
Now...
Open a command prompt type "mysql -u root -p" then hit
enter again when it requests a password.
You should now have access to the mysql monitor...
type the following at the prompts...
mysql>use mysql
mysql>select user, host, password from user;
# Now you should see that u have 3 entries
+-----------------------------+
| user | host | password |
+-----------------------------+
| root | localhost | |
| root | 127.0.0.1 | |
| | localhost | |
+-----------------------------+
mysql> delete from user where host="localhost" and user="";
mysql> update user set password=password("xxxx") where user="root";
mysql> flush tables;
mysql> flush privileges;
mysql> quit
Now the mysql table should be updated and everything fixed.
Try it out...

然后就可以用config wizard跑一遍了。

PS: 國內(nèi)和國外的水平真是差得遠，國內(nèi)的磚家們只會告訴你是和以前安裝的mysql版本沖突了，把它卸干凈，再把配置啊注冊表啊都刪干凈（簡直就是既然我不知道是哪錯了那就是全錯了），再重裝。而問題根本沒解決。。。。。。人國外的卻能一針見血地指出問題之所在。
