关于phpMyAdmin的问题

shaly

我今天在linun9.0下安装了phpMyAdmin,在浏览器里输入我的地址 显示如下信息
Notice: Undefined index: scheme in /usr/local/apache2/htdocs/phpMyAdmin/libraries/auth/cookie.auth.lib.php on line 21

Warning: Cannot modify header information - headers already sent by (output started at /usr/local/apache2/htdocs/phpMyAdmin/libraries/auth/cookie.auth.lib.php:21) in /usr/local/apache2/htdocs/phpMyAdmin/libraries/auth/cookie.auth.lib.php on line 89
phpMyAdmin


如后输入我的MySQL的登录名和密码后显示如下信息
Notice: Undefined index: scheme in /usr/local/apache2/htdocs/phpMyAdmin/libraries/auth/cookie.auth.lib.php on line 21

Warning: Cannot modify header information - headers already sent by (output started at /usr/local/apache2/htdocs/phpMyAdmin/libraries/auth/cookie.auth.lib.php:21) in /usr/local/apache2/htdocs/phpMyAdmin/libraries/auth/cookie.auth.lib.php on line 402

我应该怎么修改呢?
