unknown option '--ndbcluster'

[christophe DUMONT]

Hello,

I'm working with MySQL Server 5.7. I've added the following lines to the /etc/mysql/mysql.conf.d/mysql.cnf :

[mysqld section] : ndbcluster
[mysql_cluster]
ndb-connectstring = 192.168.56.101

whein i do : sudo systemctl start mysql, i get the error : [ERROR] unknown option '--ndbcluster'

How do i configure the mysql server to run the ndbcluster engine ?

Thx
