MariaDB主主同步,也就是两个MariaDB之间互为主从,每个MariaDB均为主、从双角色。

1. MariaDB01配置


vi /etc/my.cnf.d/server.cnf

[mysqld]

server-id = 1

log-bin = master-log

relay-log = slave-log

auto_increment_offset = 1

auto_increment_increment = 2


2. MariaDB02配置


vi /etc/my.cnf.d/server.cnf

[mysqld]

server-id = 2

log-bin = master-log

relay-log = slave-log

auto_increment_offset = 2

auto_increment_increment = 2


3. 重启MariaDB服务


root用户: sudo -u mysql service mysql restart

mysql用户:service mysql restart


4. MariaDB01主,MariaDB02从配置


MariaDB01执行:

CREATE USER 'repl'@'192.168.10.%' IDENTIFIED BY '123456';

GRANT REPLICATION SLAVE ON *.* TO 'repl'@'192.168.10.%';

show master status;


MariaDB02执行:

CHANGE MASTER TO MASTER_HOST='192.168.10.178', MASTER_USER='repl', MASTER_PASSWORD='123456', MASTER_LOG_FILE='master-log.000002', MASTER_LOG_POS=329;

start slave;

show slave status\G


5. MariaDB02主,MariaDB01从配置


MariaDB02执行:

CREATE USER 'repl'@'192.168.10.%' IDENTIFIED BY '123456';

GRANT REPLICATION SLAVE ON *.* TO 'repl'@'192.168.10.%';

show master status;


MariaDB01执行:

CHANGE MASTER TO MASTER_HOST='192.168.10.179', MASTER_USER='repl', MASTER_PASSWORD='123456', MASTER_LOG_FILE='master-log.000002', MASTER_LOG_POS=329;

start slave;

show slave status\G


至此,主主同步复制配置完成。
