Disable MySQL Replication on Slave

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;

Example

MariaDB [(none)]> show  slave status;
