我在笔记本电脑里安装mysql5.0时老是不能启动服务提示错误信息为：在本地系统上不能启动mysql服务，错误1067:进程以外终止:我装了好几次了可是不行，我用的端口是3306，那位高手帮忙看看吧！先在这谢谢了。

我在本地机子上装了mysql5.0可是我去访问数据库时却提示我:"
Client does not support authentication protocol requested by server; consider upgrading MySQL client in c:\inetpub\wwwroot\test.php on line 4
Could not connect: Client does not support authentication protocol requested by server; consider upgrading MySQL client"
不知道是什么原因？那位高手帮忙看一下了，先谢谢了！！
