Comment utiliser MySQLTuner sur Amazon RDS
J'ai installé mysqltuner localement et fonctionne sur ma base de données locale.
Lorsque j'essaie de l'exécuter sur mon Amazon RDS DB, cela ne signifie pas que mes informations d'identification de connexion ne sont pas valides.
$ Perl mysqltuner.pl --Host testing-db.??????????.us-east-1.rds.amazonaws.com --port 3306 --user admin_un --password admin_pw --forcemem 7500
[--] Performing tests on testing-db.??????????.us-east-1.rds.amazonaws.com:3306
[!!] Attempted to use login credentials, but they were invalid
Je suis capable de myssql normalement dans le DB RDS localement avec.
mysql -h testing-db.??????????.us-east-1.rds.amazonaws.com -P 3306 -u admin_un -p
Que pourrais-je manquer ici?
[~ # ~ ~] Mise à jour [~ # ~]
La base de données est sur un AWS RDS DB.M3.Large instance qui a 2 VCPUS et 7,5 GIB de RAM. J'ai configuré les paramètres de configuration MySQL comme suggéré ici dans un groupe de paramètres RDS à partir de la console AWS.

tmp_table_size = 64m
Examiner les index et la formulation de requêtes - beaucoup ont l'air inefficace (en utilisant des tables TMP, etc.)
Pour aider à identifier les requêtes coquines, recommandez Long_Query_Time = 2 et allumer le ralentisseur.
La réplication est allumée, mais les binlogs sont conservés pour toujours? Ou les RDS les purgent-ils d'une certaine manière que je ne connais pas.
Détails
(Innodb_buffer_pool_pages_free * 16384/innodb_buffer_pool_size) = 346 833 * 16384/5705302016 = 99,6% -% de la piscine tampon Free - buffer_pool_size est plus gros que le jeu de travail; pourrait le diminuer (pas critique)
(UpTime/60 * innodb_log_file_size/innodb_os_log_written) = 7 754/60 * 128m/7059968 = 2 456 minutes entre les rotations de journaux Innodb commençant par 5.6.8, cela peut être modifié de manière dynamique; Assurez-vous également de changer mon.cnf. - (La recommandation de 60 minutes entre les rotations est quelque peu arbitraire.) Ajustez Innodb_Log_File_Size. - Activité très faible sur votre serveur
(TMP_TABLE_SIZE) = 265M - Limiter la taille de [~ # ~ ~] mémoire [~ # ~] Tables Temps utilisées pour prendre en charge une sélection (max_heap_table_size/_ram) = 256m/7680m = 3,3% - pourcentage de RAM=== Pour allouer lorsqu'il nécessite une table de mémoire pour une table Temp à l'intérieur d'une table SELECT (Table par temporisation par certains choix). Trop élevé peut conduire à Swapping. (max_heap_table_size également que l'utilisateur limite les tables de mémoire.) - Diminuer les deux à la fois à, par exemple, 1% de la RAM.
(local_infile) = sur - local_infile = sur est un problème de sécurité potentiel
(Créé_tmp_disk_tables) = 45,149/7754 = 5.8/sec - fréquence de la création Disque Tables "Temps" dans le cadre de Sélection complexes (créé_tmp_disk_tables/(créé_tmp_disk_tables + Créé_tmp_tables)) = 45.149/(45149 + 113444) = 28,5% - Pourcentage des tables Temps qui sont renversées sur le disque - Vérifiez que les règles des tables temporaires sont capables d'utiliser la mémoire au lieu de MyISAM. Il peut être possible de faire un schéma mineur ou un changement de requête pour éviter MyISAM. De meilleurs indices et reformulation de requêtes peuvent également aider.
- Diminuer TMP_TABLE_SIZE POUR ÉVITER À PARTIR DE RAM. Peut-être pas plus de 64 m.
(Select_scan) = 50,953/7754 = 6,6/sec - Table complète (SELECT_SCAN/COM_SLIRECT) = 50,953/700098 = 7,3% -% de sélection de Sélectionner une analyse complète de la table. (Peut être dupe de routines stockées.) - Ajoutez des index/optimiser les requêtes (à moins que ce ne soit des tables minuscules)
(Binlog_Format) = mixte - relevé/ligne/mixte. La ligne est préférée; Cela peut devenir la valeur par défaut.
(expire_logs_days) = 0 - Combien de temps pour purger automatiquement Binlog (après plusieurs jours) - trop grand (ou zéro) = consomme de l'espace disque; Trop petit = besoin de réagir rapidement au crash de réseau/machine.
(Slow_Query_log) = Off - si vous souhaitez enregistrer des requêtes lentes. (5.1.12) (long_query_time) = 10.000000 = 10 - coupure (secondes) pour définir une requête "lente". - suggérer sur et 2
(COM_FLUSH) = 12/HR (COM_PRGE) = 12/HR - Qu'est-ce qui va tellement de flushes et de purges? Ce sont des commandes rarement utilisées.
Vous avez le cache de requête en demi-off. Vous devez définir à la fois Query_Cache_Type = OFF et QUERY_CACHE_SIZE = 0. Il y a (selon une rumeur) un "bogue" dans le code QC qui laisse du code si vous éteignez ces deux paramètres.
