MacOS Catalina Homebrew problèmes d'installation de mariadb

Edit 2020-10-12 :

Je suis sous MacOS 10.15.7, les versions dans les formules de brassage sont les suivantes 10.5.6 pour mariadb y 8.0.21 pour mysql. (vous pouvez les vérifier dans /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/{mariadb,mysql}.rb ).

Mysql fonctionne bien après une installation propre par brew uninstall mysql et de supprimer tout ce qui s'y rapporte dans $(brew --prefix) , mais mariadb ne fonctionne toujours pas avec brew unlink mysql && brew link mariadb && brew services start mariadb sans supprimer les fichiers de la base de données mysql dans $(brew --prefix) .

Question originale :

J'utilise donc MacOS 10.15.2 Catalina et j'essaie d'installer mariadb (10.4.11, la dernière version) avec Homebrew.

Après avoir exécuté brew install mariadb Dans le cadre de l'enquête sur l'état de santé de la population, Brew a prévenu que la postinstalllation ne s'est pas terminé avec succès :

==> Postinstalling mariadb

    mysql> show tables;

Try 'mysqld --help' if you have problems with paths.  Using
--general-log gives you a log in /usr/local/var/mysql that may be helpful.

Warning: The post-install step did not complete successfully
You can try again using `brew postinstall mariadb`

Je suis novice en matière de mariadb / mysql et j'ai donc suivi les instructions suivantes ce guide de mariadb.com (comme @klanomath l'a fait remarquer, ceci est dépassé (2016)) et a exécuté mysql_install_db :

$ mysql_install_db
WARNING: The host 'mymac' could not be looked up with /usr/local/Cellar/mariadb/10.4.11/bin/resolveip.
This probably means that your libc libraries are not 100 % compatible
with this binary MariaDB version. The MariaDB daemon, mysqld, should work
normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
when specifying MariaDB privileges !

J'ai fait quelques recherches mais je n'ai rien trouvé d'utile. Comment puis-je compléter mariadb installation ? Toute aide est appréciée !
