mariadb1: 192.168.11.247
mariadb2: 192.168.11.246
1 mariadb1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 mariadb2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
systemctl restart mariadb
4 mariadb1主, mariadb2从配置
mariadb1在sql里面执行:
MariaDB [(none)]> create user ‘lan‘@‘192.168.11.%‘ identified by ‘666666‘;
MariaDB [(none)]> grant replication slave on . to ‘lan‘@‘192.168.11.%‘;
show master status;
mariadb2在sql里面执行:
#log_file和log_pos的数据是mariad1上show master status得到的数据
change master to master_host=‘192.168.11.247‘, master_user=‘lan‘, master_password=‘666666‘, master_log_file=‘master-log.000001‘, master_log_pos=498;
start slave;
show slave status\G;
5 mariadb2为主, mariadb1从配置
mariadb2在sql里面执行:
MariaDB [(none)]> create user ‘lan‘@‘192.168.11.%‘ identified by ‘666666‘;
MariaDB [(none)]> grant replication slave on . to ‘lan‘@‘192.168.11.%‘;
