so i created a multi-master replication with bellow servers two for master and two for slave.
hostname : master-1 ip : 192.168.120.107
hostname : master-2 ip : 192.168.120.111
hostname : slave-1 ip : 192.168.120.117
hostname : slave-2 ip : 192.168.120.118
the two masters (master-1,master-2) are deployed as active-active replication and works well and bellow is the configuration files /etc/mysql/my.cnf :
master-1 :
[mysqld]
#
# * Basic Settings
#
server-id = 1
user = root
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
log-bin = master-bin
log-bin-index = master-bin.index
relay-log = slave-relay-bin
relay-log-index = slave-relay-bin.index
skip-external-locking
master-2 :
[mysqld]
#
# * Basic Settings
#
server-id = 2
user = root
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
log-bin = master-bin
log-bin-index = master-bin.index
relay-log = relay-log-bin
relay-log-index = relay-log-bin.index
skip-external-locking
masters work well. the two slaves are connected to the masters like this : slave-1 is the master-1 's slave and slave-2 is the master-2 's slave. and these are the configuration files :
slave-1 :
[mysqld]
#
# * Basic Settings
#
server-id = 3
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
relay-log = slave-relay-bin
relay-log-index = slave-relay-bin.index
skip-external-locking
slave-2 :
[mysqld]
#
# * Basic Settings
#
server-id = 4
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
relay-log = slave-relay-bin
relay-log-index = slave-relay-bin.index
skip-external-locking
when a master make changes to the database his slaves changes two, it mean works well for example when master-1 changes the database the changes will be replicated to master-2 and slave-1 and changes will be done in those as well. my problem is i need the changes happen in all slaves for example when master-1 changes the database ,slave-2 change his database like master-2 and slave-1. how can i make this happen?
