ERROR unknown variable > 'keyring_okv_conf_dir=/usr/local/mysql/mysql-keyring-okv' Env: Ubuntu 18.04.5 LTS + MySQL 5.7.32
I have a KMIP server working and tested. I am now trying to configuring Keyring to enable symmetric key encryption on my database
Per official docs, I added the following lines to /etc/mysql/my.cnf
[mysqld]
early-plugin-load=keyring_file.so
keyring_okv_conf_dir=/usr/local/mysql/mysql-keyring-okv

restarting mysql:
uadmin@Linux01:/var/keyring$ sudo service mysql restart
[sudo] password for uadmin:
Job for mysql.service failed because the control process exited with error 

code.
See &quot;systemctl status mysql.service&quot; and &quot;journalctl -xe&quot; for details.
