Instalação do Moodle

[juniox]

Estou tentando instalar o moodle mas surge o seguinte erro logo depois que eu especifico o banco de dados:

An error occurred while loading http://localhost/moodle/install.php:
Connection to host localhost is broken.

alguém já passou por isso?
li a FAQ no site, mas nada consta a respeito
postei no fórum também, mas não há respostas.

Bom gente, acho que o problema tá no mysql mesmo. Ele está encerrando sozinho:

--
ERROR 2013 (HY000): Lost connection to MySQL server during query
STOPPING server from pid file /var/lib/mysql/host.pid
--

fui ver o log do erro:
