Quick notes on creating a database user — MariaDB and MySQL use a combination of username and source host to determine access. This means ‘me’@’localhost’ and ‘me’@’remotehost’ can have different passwords and privilege sets. How do you know what the hostname is for your connection? I usually try to connect and read the host from the error message — it’ll say ‘someone’@’something’ cannot access the database.<\/p>\n
