Hi, I m using Openstack Stein version, I am facing an issue where i'm not able to set max connections for mariadb i have tried to set max connections parameters in "/etc/my.cnf.d/server.cnf" to 8048 but the changes doesn't reflects inside mariadb , still show only 594 max connections, looks like its not taking that parameter. I have used packstack for installing the openstack stein. Due to low max config i facing issues as after certain period the no. of connections gets full.

[root@brazilcontrollercompute0 ~(keystone_admin)]# my_print_defaults --mysqld |  grep "max_connections"
--max_connections=8048
[root@brazilcontrollercompute0 ~(keystone_admin)]#
[root@brazilcontrollercompute0 ~(keystone_admin)]# mysql -uroot -p***************
