How to delete a master-slave synchronization mysql-

I added a master-slave synchronization with a change master statement, 

 

change master to master_host='localhost',master_user='slave',master_password='123456',master_log_file='mysql-bin.000001',master_log_pos=0,master_port=3306;

 

Now due to business needs, you do not need this Slave Replication Master, when it adopts reset slave, you will find that there is synchronization information, such as: 

stop slave;

reset slave;

 

 

reset slave all

 

 

ok completely removed
