MySQL用户密码中的特殊字符叹号(!)的妙用_MySQL
使用叹号(!)禁止用户终端进入的一个方法。
代码如下:
mysql> grant all privileges on wubx.* to ‘wubx'@'172.16.100.185′ identified by ‘fd52!wubx&,';
Query OK, 0 rows affected (0.00 sec)
mysql>quit;
#mysql -h 172.16.100.185 -u wubx -pfd52!wubx&,
-bash: !wubx@,: event not found
仔细看一下,原来他把!后面的字符串做为命令执行了。又试了一个Navicat的管理端,也一样存在密码不正常的问题。
在测一下程序方面是不是可以用,写一个PHP测一下。
代码如下:
$link = mysql_connect('172.16.100.185′,'wubx','fd52!wubx&,');
if (!link){
die(‘Could not connect:'.mysql_error());
}
echo ‘Connected successfully';mysql_close($link);
?>
#php testdb.php
Connected successfully
还看程序中能正常识别。
PHP还是可以OK通过的。
