To disable MySQL Replication on the Slave server, first, edit MySQL configuration file, usually in /etc/mysql folder, remove entries like
server-id = 2 log_bin = /var/log/mysql/mariadb-bin log_bin_index = /var/log/mysql/mariadb-bin.index relay_log = /var/lib/mysql/relay-bin relay_log_index = /var/lib/mysql/relay-bin.index binlog_format=row
Also, remove any entries starting with
master- replicate-
Stop slave with command
STOP SLAVE;
Stop replication with
RESET SLAVE;
Stop MySQL
systemctl stop mysql
Remove relay logs
cd /var/lib/mysql rm -f master.info relay-*`
Start MySQL server
systemctl start mysql
You may need to re-enable events that are disabled on Slave.
select * from information_schema.events where status = 'SLAVESIDE_DISABLED';
Enable each disabled event with
alter event enable;
