mariadb -u root -p
MariaDB [(none)]> create database coturn_db default character set utf8mb4;
MariaDB [(none)]> grant all on coturn_db.* to coturn_USER_4 identified by 'coturn_PASSPass8';

mariadb coturn_db -u root -p < /usr/share/coturn/schema.sql

turnadmin -k -u webrtc_user_5 -r janus.jogrid.net -p webrtc_pass_23

0x205bbb5552ff14bb6269d59cb30dfd96
