Query OK, 0 rows affected (0.00 sec)
4) 拷贝debian.cnf
将/etc/mysql/debian.cnf 从 DB1拷贝到DB2, 这个文件是用来启动和关闭mysql用的。
| (db1)# scp debian.cnf root@192.168.0.11:/tmp/ |
在DB2上备份原来的debian.cnf，然后使用从DB1拷贝过来的debian.cnf
| (db2)# mv /etc/mysql/debian.cnf /etc/mysql/debian.cnf.orign (db2)# cp -f debian.cnf /etc/mysql/debian.cnf |
上述步骤完成后准备工作都做好了，可以开始配置复制。
四、 复制配置
1. 在DB2上执行：
| (db2)mysql> CHANGE MASTER TO master_host='192.168.0.10', master_port=3306, master_user='replication', master_password='123456', master_log_file='mysql-bin.000002', master_log_pos=616; Query OK, 0 rows affected (0.04 sec) |
注：master_log_file='mysql-bin.000002', master_log_pos=616 信息来自于在DB1上执行
mysql> show master status;
2. 在DB2上启动SLAVE
| (db2)mysql> START SLAVE; Query OK, 0 rows affected (0.00 sec) |
3. DB2上检查复制进程
| (db2)mysql> SHOW SLAVE STATUS\G *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 192.168.0.10 Master_User: replication Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000002 Read_Master_Log_Pos: 616 Relay_Log_File: mysql-relay-bin.000002 Relay_Log_Pos: 253 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: 616 Relay_Log_Space: 409 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 1 row in set (0.00 sec) |
4. 配置从DB2复制到DB1
1) DB2状态
| (db2)mysql> SHOW MASTER STATUS; +------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | +------------------+----------+--------------+------------------+ | mysql-bin.000002 | 107 | | | +------------------+----------+--------------+------------------+ 1 row in set (0.01 sec) mysql> |
2) DB1复制的配置、启动和检查
| (db1)mysql> CHANGE MASTER TO master_host = '192.168.0.11', master_port=3306, master_user='replication', -> master_password='123456', master_log_file='mysql-bin.000002', master_log_pos=107; Query OK, 0 rows affected (0.05 sec)
mysql> START SLAVE; Query OK, 0 rows affected (0.00 sec)
mysql> SHOW SLAVE STATUS\G *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 192.168.0.11 Master_User: replication Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000002 Read_Master_Log_Pos: 107 Relay_Log_File: mysql-relay-bin.000002 Relay_Log_Pos: 253 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: 107 Relay_Log_Space: 409 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_Fil |
