Steps for configuring the MySQL Master/Slave Server

Environment:

         Master：               ip 192.168.1.110               os rhel-5.8               mysql 5.5.28         Slave：               ip 192.168.1.113               os rhel-5.8               mysql 5.5.28

① Configure master my. CNF

[Root @ localhost ~] # Cat/etc/My. CNF [mysqld] Log-bin = mysql-bin # Open MySQL binary log BINLOG-do-DB = test # Set the database server-id = 1 # Set mysql_id, the master and slave nodes cannot be the same as BINLOG-ignore-DB = MySQL # Set the database sync_binlog not recorded in binary log = 1 # refresh to disk when BINLOG is updated

 

② Log on to the master database

use mysql;grant replication slave,file on *.* to 'Think'@'192.168.1.113' identified by 'mysql';flush privileges;

View the status of the master database and record file and Position

mysql> show master status\G;*************************** 1. row ***************************            File: mysql-bin.000002        Position: 107    Binlog_Do_DB: testBinlog_Ignore_DB: mysql1 row in set (0.00 sec)

 

③ Configuration from my. CNF

[root@localhost ~]# cat /etc/my.cnf[mysqld]log-bin=mysql-binserver-id       = 2replicate-do-db=testreplicate-ignore-db=mysqllog-slave-updatessync_binlog=1slave-net-timeout=10

 

④ Slave Database Change master

mysql> stop slave;Query OK, 0 rows affected, 1 warning (0.00 sec)mysql> change master to    -> master_host='192.168.1.110',master_user='Think',master_password='mysql',    -> master_log_file='mysql-bin.000002',master_log_pos=107;Query OK, 0 rows affected (0.10 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: 192.168.1.110                  Master_User: Think                  Master_Port: 3306                Connect_Retry: 60              Master_Log_File: mysql-bin.000002          Read_Master_Log_Pos: 107               Relay_Log_File: localhost-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: test          Replicate_Ignore_DB: mysql           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: 413              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: 0Master_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: 11 row in set (0.00 sec)

 

⑤ Verify Synchronization
Master database:

mysql> use test;Reading table information for completion of table and column namesYou can turn off this feature to get a quicker startup with -ADatabase changedmysql> show tables;+----------------+| Tables_in_test |+----------------+| bin            || servers        || water          |+----------------+3 rows in set (0.00 sec)mysql> insert into bin values(1);Query OK, 1 row affected (0.12 sec)

Slave database:

mysql> use test;Reading table information for completion of table and column namesYou can turn off this feature to get a quicker startup with -ADatabase changedmysql> show tables;+----------------+| Tables_in_test |+----------------+| bin            || sales          || t              |+----------------+3 rows in set (0.00 sec)mysql> select * from bin;+------+| id   |+------+|    1 |+------+1 row in set (0.00 sec)
