今天偶然想到去更新一下机子里面PHP的版本，然后重新去wamp官网下载了WAMP（wamp 64 Apache : 2.4.9 MySQL : 5.6.17 PHP : 5.5.12 PHPMyAdmin : 4.1.14 SqlBuddy : 1.3.3 XDebug : 2.2.5）。
安装之后修改 D:/wamp/bin/mysql/mysql5.6.17/my.ini，发现修改了datadir目录无法生效，感觉想写死在程序里面一样。
重新测试：
将D:/wamp/bin/mysql/mysql5.6.17/data 复制到 D:/wamp/bin/mysql/mysql5.6.17/data2
my.ini中将默认的 datadir=d:/wamp/bin/mysql/mysql5.6.17/data 改成 datadir=d:/wamp/bin/mysql/mysql5.6.17/data2，可不管怎么改，重启之后wamp的mysql的datadir地址仍旧是 d:/wamp/bin/mysql/mysql5.6.17/data，如果我将 d:/wamp/bin/mysql/mysql5.6.17/data 这个目录删除，那么就无法重启。
我以前每次下载wamp都非常方便修改datadir的，改这个datadir参数重启就可以的
，但是今天下载来的却怎么修改都无法改动，固定了一样。现在尚未解决，如果您知道这个的解决方法，请告诉我一下default7#zbphp.com
