主主同步原理同主从，不过是双向而已

1.修改1.4配置文件

vim /etc/my.cnf #同时开始binlog和relay log log-bin=mysql-bin binlog_format=mixed server-id = 1 sync_master_info = 1 sync_binlog = 1  innodb_support_xa = ON relay_log= relay-log relay_log_index=relay-log.index skip_slave_start = ON sync_relay_log = 1 sync_relay_log_info = 1 #定义偏移量 auto_increment_offset=1 auto_increment_increment=2

2.查看1.4日志POS点

MariaDB [(none)]> show master status\G *************************** 1. row ***************************             File: mysql-bin.000002         Position: 662     Binlog_Do_DB:  Binlog_Ignore_DB:  1 row in set (0.00 sec)

3.修改1.5配置文件

vim /etc/my.cnf #同时开始binlog和relay log log-bin=mysql-bin binlog_format=mixed server-id = 3 sync_master_info = 1 sync_binlog = 1 innodb_support_xa = ON relay_log= relay-log relay_log_index=relay-log.index skip_slave_start = ON sync_relay_log = 1 sync_relay_log_info = 1 #定义偏移量 auto_increment_offset = 2

4.查看1.5日志POS点

MariaDB [mysql]> show master status\G *************************** 1. row ***************************             File: mysql-bin.000001         Position: 1073     Binlog_Do_DB:  Binlog_Ignore_DB:  1 row in set (0.00 sec)

5.在1.4上添加复制用户

MariaDB [(none)]> grant replication slave,replication client on *.* to 'repa'@'192.168.1.5' identified by 'slavepass';      Query OK, 0 rows affected (0.09 sec)

6.在1.5上添加复制用户

MariaDB [mysql]> grant replication slave,replication client on *.* to 'repb'@'192.168.1.4' identified by 'slavepass';   Query OK, 0 rows affected (0.07 sec)

7.在1.4上开始同步复制

change master to master_host='192.168.1.5',master_user='repb',master_password='slavepass',master_log_file='mysql-bin.000001',master_log_pos=1073;

8.在1.5上开始同步复制

change master to master_host='192.168.1.4',master_user='repa',master_password='slavepass',master_log_file='mysql-bin.000002',master_log_pos=662;

9.查看1.4同步状态

MariaDB [(none)]> show slave status\G *************************** 1. row ***************************                Slave_IO_State: Waiting for master to send event                   Master_Host: 192.168.1.5                   Master_User: repb                   Master_Port: 3306                 Connect_Retry: 60               Master_Log_File: mysql-bin.000001           Read_Master_Log_Pos: 1073                Relay_Log_File: relay-log.000002                 Relay_Log_Pos: 537         Relay_Master_Log_File: mysql-bin.000001              Slave_IO_Running: Yes             Slave_SQL_Running: Yes               Replicate_Do_DB:            Replicate_Ignore_DB:             Replicate_Do_Table:         Replicate_Ignore_Table:        Replicate_Wild_Do_Table:    Replicate_Wild_Ignore_Table:                     Last_Errno: 0                    Last_Error:                   Skip_Counter: 0           Exec_Master_Log_Pos: 1073               Relay_Log_Space: 829               Until_Condition: None                Until_Log_File:                  Until_Log_Pos: 0            Master_SSL_Allowed: No            Master_SSL_CA_File:             Master_SSL_CA_Path:                Master_SSL_Cert:              Master_SSL_Cipher:                 Master_SSL_Key:          Seconds_Behind_Master: 0 Master_SSL_Verify_Server_Cert: No                 Last_IO_Errno: 0                 Last_IO_Error:                 Last_SQL_Errno: 0                Last_SQL_Error:    Replicate_Ignore_Server_Ids:               Master_Server_Id: 3                Master_SSL_Crl:             Master_SSL_Crlpath:                     Using_Gtid: No                   Gtid_IO_Pos:        Replicate_Do_Domain_Ids:    Replicate_Ignore_Domain_Ids:                  Parallel_Mode: conservative 1 row in set (0.00 sec)

10.查看1.5同步状态

MariaDB [mysql]> show slave status\G *************************** 1. row ***************************                Slave_IO_State: Waiting for master to send event                   Master_Host: 192.168.1.4                   Master_User: repa                   Master_Port: 3306                 Connect_Retry: 60               Master_Log_File: mysql-bin.000002           Read_Master_Log_Pos: 662                Relay_Log_File: relay-log.000002                 Relay_Log_Pos: 537         Relay_Master_Log_File: mysql-bin.000002              Slave_IO_Running: Yes             Slave_SQL_Running: Yes               Replicate_Do_DB:            Replicate_Ignore_DB:             Replicate_Do_Table:         Replicate_Ignore_Table:        Replicate_Wild_Do_Table:    Replicate_Wild_Ignore_Table:                     Last_Errno: 0                    Last_Error:                   Skip_Counter: 0           Exec_Master_Log_Pos: 662               Relay_Log_Space: 829               Until_Condition: None                Until_Log_File:                  Until_Log_Pos: 0            Master_SSL_Allowed: No            Master_SSL_CA_File:             Master_SSL_CA_Path:                Master_SSL_Cert:              Master_SSL_Cipher:                 Master_SSL_Key:          Seconds_Behind_Master: 0 Master_SSL_Verify_Server_Cert: No                 Last_IO_Errno: 0                 Last_IO_Error:                 Last_SQL_Errno: 0                Last_SQL_Error:    Replicate_Ignore_Server_Ids:               Master_Server_Id: 1                Master_SSL_Crl:             Master_SSL_Crlpath:                     Using_Gtid: No                   Gtid_IO_Pos:        Replicate_Do_Domain_Ids:    Replicate_Ignore_Domain_Ids:                  Parallel_Mode: conservative 1 row in set (0.00 sec)

11.在1.4上创建数据库及表

MariaDB [(none)]> create database prince; Query OK, 1 row affected (0.09 sec) MariaDB [(none)]> use prince; Database changed MariaDB [prince]> drop table Threek; Query OK, 0 rows affected (0.13 sec)

创建表：

MariaDB [prince]> create table Threek(id int auto_increment primary key,name varchar(50)); Query OK, 0 rows affected (0.26 sec)

插入数据

MariaDB [prince]> insert into Threek (name) values('wukaka'),('ckl'),('love'); Query OK, 3 rows affected (0.06 sec) Records: 3  Duplicates: 0  Warnings: 0MariaDB [prince]> select * from Threek; +----+--------+ | id | name   | +----+--------+ |  1 | wukaka | |  3 | ckl    | |  5 | love   | +----+--------+ 3 rows in set (0.00 sec)

12.在1.5上插入数据

MariaDB [(none)]> use prince; Database changed

查看表：

MariaDB [prince]> show tables; +------------------+ | Tables_in_prince | +------------------+ | Threek           | +------------------+ 1 row in set (0.00 sec)

查看数据

MariaDB [prince]> select * from Threek; +----+--------+ | id | name   | +----+--------+ |  1 | wukaka | |  3 | ckl    | |  5 | love   | +----+--------+ 3 rows in set (0.00 sec)

插入数据：

MariaDB [prince]> insert into Threek (name) values('stack'),('ayia'),('snow'); Query OK, 3 rows affected (0.06 sec) Records: 3  Duplicates: 0  Warnings: 0 MariaDB [prince]> select * from Threek;                                        +----+--------+ | id | name   | +----+--------+ |  1 | wukaka | |  3 | ckl    | |  5 | love   | |  6 | stack  | |  7 | ayia   | |  8 | snow   | +----+--------+ 6 rows in set (0.00 sec)

13.在1.4上查看数据

MariaDB [prince]> select * from Threek; +----+--------+ | id | name   | +----+--------+ |  1 | wukaka | |  3 | ckl    | |  5 | love   | |  6 | stack  | |  7 | ayia   | |  8 | snow   | +----+--------+ 6 rows in set (0.00 sec)
