MariaDB-10.2 unable to set max_connections and wait_timeout through etc/my.cnf

Hello,

I am using Linux Amazon Linux 2 and MariaDB 10.2. I want to set value for max_connections and wait_timeout. But there no value set in my current etc/my.cnf file.

This is my etc/my.cnf:
Quote:

#cat /etc/my.cnf # # This group is read both both by the client and the server # use it for options that affect everything # [client-server] # # This group is read by the server # [mysqld] # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 # # include all files from the config directory # !includedir /etc/my.cnf.d

It will be great help of someone please let me know how can I check my current value and set new value for both.

Thanks in advance.
