1,关闭你现在正在运行的mysql数据库,用结束mysql进程或者直接关闭mysql服务器都可以
2,关闭数据库后,运行点击开始运行,输入cmd进入命令行窗口,在这个命令行中操作进入到你数据库所在的安装路径,一般默认安装的话都会在c:Program FilesMySQLMySQL Server 5.0bin
3,在这个路径下输入 mysqld --skip-grant-tables 然后回车,这段命令的意思就是从安全模式下启动数据库
4,只要上述步骤成功的话,这个cmd窗口会一直有个小光标出现,,然后没有任何提示弹出来,这代表你的数据库已经启动了,这时候重新在打开一个cmd窗口,同样进入到mysql数据库的安装路径下,然后输入mysql -uroot -p,这个命令的意思是使用空密码的方式登录MySQL,成功的话就会看到一个mysql>这样的提示,最后在这个提示下输入update mysql.user set password=PASSWORD('新密码') where User='root';
,在新密码中输入你要修改的密码,然后关掉所有的cmd窗口,按照第一步的操作关掉你的服务器,然后按正常步骤再次运行你的服务器,这时候你root的密码就改成你刚才设置的新密码了。
