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.
  23. [mysqld_safe]
  24. socket          = /var/run/mysqld/mysqld.sock
  25. nice            = 0
  26. [mysqld]
  27. #
  28. # * Basic Settings
  29. #
  30. user            = mysql

  36. tmpdir          = /tmp
  37. language        = /usr/share/mysql/english
  38. skip-external-locking
  39. #
  40. # Instead of skip-networking the default is now to listen only on
  41. # localhost which is more compatible and is not less secure.
  42. bind-address            = 127.0.0.1
  43. #
  44. # * Fine Tuning
  45. #
  46. key_buffer              = 128M

  48. thread_stack            = 128K

  66. #
  67. # * Logging and Replication
  68. #
  69. # Both location gets rotated by the cronjob.
  70. # Be aware that this log type is a performance killer.
  71. #log            = /var/log/mysql/mysql.log
  72. #
  73. # Error logging goes to syslog. This is a Debian improvement :)
  74. #
  75. # Here you can see queries with especially long duration
  76. #log_slow_queries       = /var/log/mysql/mysql-slow.log
  77. #long_query_time = 2
  78. #log-queries-not-using-indexes
  79. #
  80. # The following can be used as easy to replay backup logs or for replication.
  81. # note: if you are setting up a replication slave, see README.Debian about
  82. #       other settings you may need to change.
  83. #server-id              = 1

  88. #binlog_ignore_db       = include_database_name
  89. #
  90. # * BerkeleyDB
  91. #
  92. # Using BerkeleyDB is now discouraged as its support will cease in 5.1.12.
  93. skip-bdb
  94. #
  95. # * InnoDB
  96. #
  97. # InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/.
  98. # Read the manual for more InnoDB related options. There are many!
  99. # You might want to disable InnoDB to shrink the mysqld process by circa 100MB.
  100. #skip-innodb
  101. #
  102. # * Security Features
  103. #
  104. # Read the manual, too, if you want chroot!
  105. # chroot = /var/lib/mysql/
  106. #
  107. # For generating SSL certificates I recommend the OpenSSL GUI "tinyca".
  108. #
  109. # ssl-ca=/etc/mysql/cacert.pem
  110. # ssl-cert=/etc/mysql/server-cert.pem
  111. # ssl-key=/etc/mysql/server-key.pem
  112. [mysqldump]
  113. quick
  114. quote-names
  115. max_allowed_packet      = 16M
  116. [mysql]
  117. #no-auto-rehash # faster start of mysql but no tab completition
  118. [isamchk]
  119. key_buffer              = 16M
  120. #
  121. # * NDB Cluster
  122. #
  123. # See /usr/share/doc/mysql-server-*/README.Debian for more information.
  124. #
  125. # The following configuration is read by the NDB Data Nodes (ndbd processes)
  126. # not from the NDB Management Nodes (ndb_mgmd processes).
  127. #
  128. # [MYSQL_CLUSTER]
  129. # ndb-connectstring=127.0.0.1
  130. #
  131. # * IMPORTANT: Additional settings that can override those from this file!
  132. #   The files must end with '.cnf', otherwise they'll be ignored.

Merci d'avance !
