Bonjour
Je souhaite optimiser mon my.cnf pour un gros forum phpbb, je dispose d'un serveur puissant avec 4GB de RAM mais je doute fortement que ma conf soit optimisee
 
des conseils?
 

Code :
  1. # The MySQL database server configuration file.
  2. #
  3. # You can copy this to one of:
  4. # - "/etc/mysql/my.cnf" to set global options,
  5. # - "~/.my.cnf" to set user-specific options.
  6. #
  7. # One can use all long options that the program supports.
  8. # Run program with --help to get a list of available options and with
  9. # --print-defaults to see which it would actually understand and use.
  10. #
  11. # For explanations see
  12. # http://dev.mysql.com/doc/mysql/en/ [...] ables.html
  13. # This will be passed to all mysql clients
  14. # It has been reported that passwords should be enclosed with ticks/quotes
  15. # escpecially if they contain "#" chars...
  16. # Remember to edit /etc/mysql/debian.cnf when changing the socket location.
  17. [client]
  18. port            = 3306
  19. socket          = /var/run/mysqld/mysqld.sock
  20. # Here is entries for some specific programs
  21. # The following values assume you have at least 32M ram
  22. # This was formally known as [safe_mysqld]. Both versions are currently parsed.

  103. #
  104. # Read the manual, too, if you want chroot!
