Impossible d'installer MySQL 5.7 sur un serveur sans compte root

Question

J'utilise un serveur d'hébergement qui ne me fournit pas de compte root. Ils ne me fournissent pas un service d'installation de base de données. Le serveur est la version 6.1 (Santiago) x86_64 de Red Hat Enterprise Linux Server.

J'ai essayé de télécharger et installer MySQL 5.7.10, mais il me montre des erreurs concernant la configuration de InnoDB comme ci-dessous:

[hoge@blackett mysql]$ ./bin/mysqld --initialize --basedir=/home/hoge/mysql --character-set-server=utf8

J'ai aussi ce qui suit:

cp ./support-files/my-default.cnf ~/my.cnf 

J'ai essayé le commande suivante, mais il me donne les mêmes erreurs:

[hoge@blackett mysql]$ ./bin/mysqld --initialize --character-set-server=utf8 --basedir=/home/hoge/mysql --defaults-file=/home/hoge/my.cnf 

J'ai écrit ce qui suit dans my.cnf, mais doesn ne résoudra pas l'erreur:

innodb_use_native_aio = 0 

Je n'ai aucune idée pour les résoudre. Pourriez-vous s'il vous plaît me contacter?

Answer 1

Peut-être ...

On Linux systems, running multiple MySQL servers (typically more than 12) with default settings for innodb_read_io_threads, innodb_write_io_threads, and the Linux aio-max-nr setting can exceed system limits. Ideally, increase the aio-max-nr setting; as a workaround, you might reduce the settings for one or both of the MySQL configuration options.

Answer 2

Je résolu la question moi-même.

Le document https://dev.mysql.com/doc/refman/5.7/en/data-directory-initialization-mysqld.html dit

the --defaults-file option must be first

Quand je tapais ./bin/mysqld --defaults-file=/home/hoge/my.cnf --initialize --character-set-server=utf8 --basedir=/home/hoge/mysql, le fichier d'options a été reconnu.

Une autre solution consiste à spécifier --innodb_use_native_aio=0 directement sans avoir le fichier d'options, my.cnf, comme ci-dessous:

./bin/mysqld --initialize --basedir=/home/utpsy/mysql --character-set-server=utf8 --innodb_use_native_aio=0
