配置phpMyAdmin时提示配置文件中的密文（blowfish_secret）太短
解决办法：
将phpMyAdmin目录下的config.inc.php（默认为config.sample.inc.php）配置文件中的$cfg[‘blowfish_secret’]值随便设置为一个够32位的值（字符串）解决问题。
/** * This is needed for cookie based authentication to encrypt password in * cookie. Needs to be 32 chars long. */ $cfg['blowfish_secret'] = 'abcdefghijklmnopqrstuvwxyzabcdefgh'; /* YOU SHOULD CHANGE THIS FOR A MORE SECURE COOKIE AUTH! */
