Problemas Generales

De ante mano muchas gracias por escribir, si la verdad de que antes de instalar moodle 2.8 se realizo un tunning a la base de datos, estoy trabajando con mariadb y puede ser que mi configuración del archivo my.cnf no se la adecuada o el tunning que realice no fue bien ejecutado, utilice mysqlturner para poder ajustar mis variables.

la configuración es la siguiente:

#

# The MySQL database server configuration file.

#

# You can copy this to one of:

# - "/etc/mysql/my.cnf" to set global options,

# - "~/.my.cnf" to set user-specific options.

# 

# One can use all long options that the program supports.

# Run program with --help to get a list of available options and with

# --print-defaults to see which it would actually understand and use.

#

# For explanations see

# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

# This will be passed to all mysql clients

# It has been reported that passwords should be enclosed with ticks/quotes

# escpecially if they contain "#" chars...

# Remember to edit /etc/mysql/debian.cnf when changing the socket location.

[client]

port= 3306

socket= /var/run/mysqld/mysqld.sock

# Instead of skip-networking the default is now to listen only on
