How Configure MYSQL master-master replication

Assume

Master1 = 172.16.1.1
Master2 = 172.16.1.2


Database users
GRANT ALL PRIVILEGES ON *.* TO 'slaveuser'@'localhost'IDENTIFIED BY 'slavepw' WITH GRANT OPTION;
GRANT ALL PRIVILEGES ON *.* TO 'slaveuser'@'%' IDENTIFIED BY 'slavepw' WITH GRANT OPTION;

Master1

=========================================================
[mysqld]
auto_increment_increment=2
auto_increment_offset=1

# Replication Master Server
# binary logging is required for replication

log-bin=master1-bin
binlog-ignore-db=mysql
binlog-ignore-db=test

# required unique id between 1 and 2^32 - 1
server-id = 1

#following is the slave settings so this server can connect to master2

master-host = 172.16.1.2
master-user = slaveuser
master-password = slavepw
master-port = 3306

#If you want to enable log add this entry for [mysqld] section:
log-error=/var/log/mysqld.log

========================================================


Master 2

==========================================================
[mysqld]


auto_increment_increment=2
auto_increment_offset=2

# Replication Master Server
# binary logging is required for replication

log-bin=master2-bin
binlog-ignore-db=mysql
binlog-ignore-db=test

# required unique id between 1 and 2^32 - 1
server-id = 2

#following is the slave settings so this server can connect to master2
master-host = 172.16.1.1
master-user = slaveuser
master-password = slavepw
master-port = 3306

#If you want to enable log add this entry for [mysqld] section:
log-error=/var/log/mysqld.log

==============================================================



Master 1

grant replication slave on *.* to slaveuser@'172.16.1.2' identified by 'slavepw';

Master 2

grant replication slave on *.* to slaveuser@'172.16.1.1' identified by 'slavepw';


=============================================
Restart both
