I have installed and configured collation in my.conf. still getting collation error.
Attached is the error screen shot
What version of MariaDB server?
See the collection-server
sudo nano /etc/mysql/my.cnf
[mysqld]
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
#this block should be in bottom
[mysql]
default-character-set = utf8mb4
systemctl restart mariadb
Thanks for your comments, i resolved this issue by copying my.cnf to mariadb.conf.d directory
