MYSQL Server shows it is master server in replication. How to turn off this? I'm using Ubuntu 20.04 version. I have installed MySQL server using apt-get install mysql-server and used mysql_secure_installation for security. Then I have installed phpMyAdmin using apt-get install phpmyadmin.
Opening phpMyAdmin's status tab shows This MySQL server works as master in replication process

Can anyone help me to stop this replication process?
I found nothing about this replication in my.cnf configuration file.
my.cnf file
The MySQL database server configuration file.
#
# You can copy this to one of:
# - &quot;/etc/mysql/my.cnf&quot; to set global options,
# - &quot;~/.my.cnf&quot; to set user-specific options.
# 
# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

#
# * IMPORTANT: Additional settings that can override those from this file!
#   The files must end with '.cnf', otherwise they'll be ignored.
#

!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/
I added below segement at the end of the my.cnf file.
It solved the problem.
[mysqld]
skip-log-bin

Currently my my.cnf file looks like:
