PhpMyAdmin install errors

Question

I've just installed phpmyadmin on Linux Fedora 13 with PHP 5.3.3. I get the following 2 errors:

First: I get this on the login screen:

Cannot load mcrypt extension. Please check your PHP configuration.

-The solutions I googled for this one was to yum install mcrypt and enable it in /etc/php.ini with

extension=php_mcrypt.dll
extension=php_mcrypt_filter.dll

Did all that, but no go.

This second one shows up when I login:

The mbstring PHP extension was not found and you seem to be using a multibyte charset. Without the mbstring extension phpMyAdmin is unable to split strings correctly and it may result in unexpected results.

Wondering a) How can I fix these and b) What do they affect?

Thanks-

Answer 1

FULL ANSWER:

yum install php-mycrypt
yum install php-mbstring

no php.ini editing needed

Thanks to goreSplatter for shoving me in right direction

Answer 2

Look which resource file is being loaded by examining $_SERVER['PHPRC']. This value points to the directory where PHP looks for php.ini. I doubt that it's /etc.

Then install the right package, which is php-mcrypt.
