### Bases:

Les bases sont stockées ici: `/usr/local/var/mysql`

### Fichier de configuration:

my.cnf:

```
#osx (Homebrew): /usr/local/etc/my.cnf

[mysqld]
#innodb_force_recovery = 1
```

### Erreurs:

```bash
$ mysql -v -u root -p
mysql: Can't read dir of '/usr/local/etc/my.cnf.d' (Errcode: 2 "No such file or directory")
Fatal error in defaults handling. Program aborted
```

Le répertoire `/usr/local/etc/my.cnf.d` n'existe plus, il faut le recréer et y créer un fichier:

```bash
$ mkdir /usr/local/etc/my.cnf.d
$ touch wont_prune.txt
```
