Quando vou ao phpmyadmin, diz:
The mysqli extension is missing. Please check your PHP configuration. <a href="Documentation.html#faqmysql" target="documentation"><img src="themes/dot.gif" title="Documentation" alt="Documentation" class="icon ic_b_help" /></a>
Eu também tive wordpress instalado, diz:
Your PHP installation appears to be missing the MySQL extension which is required by WordPress.
Portanto, a extensão php mysql não está funcionando, mas está instalada.

Removing php5-mysql ...

The Apache error log may have more information.
Your apache2 configuration is broken, so we're not restarting it for you.
Errors were encountered while processing:
php5-mysql
E: Sub-process /usr/bin/dpkg returned an error code (1)
Nota: Tudo estava funcionando bem até que eu removi alguma pasta (talvez apache2), então quando eu tentei instalar o LAMP novamente eu tenho problemas.
O mysqli está incluído no pacote php5-mysql. Execute um script php contendo phpinfo() e verifique se o suporte MySQLi está habilitado.
Se não estiver, você deve editar sua configuração do PHP. Se não estiver presente adicione a seguinte linha ao seu arquivo php.ini:
extension=mysqli.so
(reinicie o Apache depois)
