MySQL主主同步
主主同步原理同主從，不過是雙向而已
1.修改1.4配置文件
vim /etc/my.cnf #同時開始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 #定義偏移量 auto_increment_offset=1 auto_increment_increment=2
2.查看1.4日志POS點
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 #同時開始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 #定義偏移量 auto_increment_offset = 2
4.查看1.5日志POS點
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上添加復制用戶
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上添加復制用戶
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上開始同步復制
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上開始同步復制
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同步狀態
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同步狀態
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上創建數據庫及表
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)
創建表：
MariaDB [prince]> create table Threek(id int auto_increment primary key,name varchar(50)); Query OK, 0 rows affected (0.26 sec)
插入數據
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上插入數據
MariaDB [(none)]> use prince; Database changed
查看表：
MariaDB [prince]> show tables; +------------------+ | Tables_in_prince | +------------------+ | Threek | +------------------+ 1 row in set (0.00 sec)
查看數據
MariaDB [prince]> select * from Threek; +----+--------+ | id | name | +----+--------+ | 1 | wukaka | | 3 | ckl | | 5 | love | +----+--------+ 3 rows in set (0.00 sec)
插入數據：
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上查看數據
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)
