在192.168.1.202上将192.168.1.201设为自己的主服务器
MySQL> change master to master_host='192.168.1.201',master_user='replication',master_password='replication',master_log_file='MySQL-bin.000003',master_log_pos=374; 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: 192.168.1.201 Master_User: replication Master_Port: 3306 Connect_Retry: 60 Master_Log_File: MySQL-bin.000003 Read_Master_Log_Pos: 374 Relay_Log_File: MySQL-master2-relay-bin.000002 Relay_Log_Pos: 235 Relay_Master_Log_File: MySQL-bin.000003 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: 374 Relay_Log_Space: 235 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 1 row in set (0.00 sec)
3、将192.168.1.202设为192.168.1.201的主服务器
在192.168.1.202上新建授权用户
MySQL> grant replication slave on *.* to 'replication'@'%' identified by 'replication'; Query OK, 0 rows affected (0.00 sec) MySQL> show master status; +------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | +------------------+----------+--------------+------------------+ | MySQL-bin.000003 | 374 | | | +------------------+----------+--------------+------------------+ 1 row in set (0.00 sec)
在192.168.1.201上，将192.168.1.202设为自己的主服务器
MySQL> change master to master_host='192.168.1.202',master_user='replication',master_password='replication',master_log_file='MySQL-bin.000003',master_log_pos=374; 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: 192.168.1.202 Master_User: replication Master_Port: 3306 Connect_Retry: 60 Master_Log_File: MySQL-bin.000003 Read_Master_Log_Pos: 374 Relay_Log_File: MySQL-master1-relay-bin.000002 Relay_Log_Pos: 235 Relay_Master_Log_File: MySQL-bin.000003 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: 374 Relay_Log_Space: 235 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
