WAMP中如何修改mysql默认空密码_MySQL
bitsCN.com
WAMP安装好后，mysql教程密码是为空的，那么要如何修改呢？其实很简单，通过几条指令就行了，下面我就一步步来操作。
首先，通过WAMP打开mysql控制台。
提示输入密码，因为现在是空，所以直接按回车。
然后输入“use mysql”，意思是使用mysql这个数据库教程，提示“Database changed”就行。
然后输入要修改的密码的sql语句“update user set password=PASSWORD（'hooray'）where user='root'；”，注意，sql语句结尾的分号不能少，提示什么什么OK就行了。
最后输入“flush privileges；”，不输入这个的话，修改密码的操作不会生效的。
然后输入“quit”退出。
另外，很多人说通过php教程myadmin直接修改mysql表里的密码就行，原理上应该是没错，但是我发现修改后mysql整个库都不见了，害的我重装了WAMP，最终还是通过命令行去修改的。
大家可以摸索下，其实操作并不困难，因为我发现同事电脑上的mysql都是空密码，这以后要是配服务器，也弄个空密码还不完蛋。
