解决MySQL安装时1045错误的方法

该错误只在Windows系统上出现，Linux下好像好没有，据说这个错误已经存在n年了，有人extremely dispointed that it still exists

该错误只在Windows系统上出现，Linux下好像好没有，据说这个错误已经存在n年了，有人extremely dispointed that it still exists here in 2009!

错误的原因更令人抓狂，，那就是mysql server instance config wizard根本没有为你设密码，于是root密码是空！实在不明白如果没有为我设密码那中间为什么叫我设个密码。

解决办法：

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: 国内和国外的水平真是差得远，国内的砖家们只会告诉你是和以前安装的mysql版本冲突了，把它卸干净，再把配置啊注册表啊都删干净（简直就是既然我不知道是哪错了那就是全错了），再重装。而问题根本没解决。。。。。。人国外的却能一针见血地指出问题之所在。
