Paigaldamine tavalisest paketihaldusest

# apt-get install mariadb-server

Seadistamine

Debian v. 11 operatsioonisüsteemi puhul kasutatakse vaikimisi utf8mb4, vt

/etc/mysql/mariadb.conf.d/50-server.cnf

st andmebaasi ja kasutajat on loomulik moodustada selliselt, nt wordpress jaoks sobib väga hästi
