How to setup a master to master replication on mysql server 5.527.07.15

Server A:

1.
edit file /etc/mysql/my.cnf

server-id               = 1
log_bin                 = /var/log/mysql/mysql-bin.log
expire_logs_days        = 10
max_binlog_size         = 500M
binlog_do_db            = shopsql1
binlog_ignore_db        = shopsql2

2
create replicator user in mysql client>>

create user 'replicator'@'%' identified by 'PASS'; 
grant replication slave on *.* to 'replicator'@'%';

3.
run in mysql client

SHOW MASTER STATUS;

and notice File and Position

Server B:

same 3 steps but change 
server-id               = 1

to 
server-id               = 2

Now you need to enter the starting mnaster_host config on both server
Server A:

slave stop; 
CHANGE MASTER TO MASTER_HOST = 'IP of server B', MASTER_USER = 'replicator', MASTER_PASSWORD = 'PASS', MASTER_LOG_FILE = '
file of server B', MASTER_LOG_POS = position_of_server_b; 
slave start;

Server B:

slave stop; 
CHANGE MASTER TO MASTER_HOST = 'IP of server A', MASTER_USER = 'replicator', MASTER_PASSWORD = 'PASS', MASTER_LOG_FILE = '
file of server A', MASTER_LOG_POS = position_of_server_a; 
slave start;
