环境:
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 主my.cnf的配置
[root@localhost ~]# cat /etc/my.cnf [mysqld] log-bin=mysql-bin #打开mysql二进制日志 binlog-do-db=test #设置二进制日志记录的库 server-id = 1 #设置mysql_id,主从不能相同 binlog-ignore-db=mysql #设置二进制日志不记录的库 sync_binlog=1 #设置binlog有更新的时候刷新到磁盘
② 登入主库
use mysql; grant replication slave,file on *.* to 'Think'@'192.168.1.113' identified by 'mysql'; flush privileges;
查看主库状态,并记录File和Position
mysql> show master status\G; *************************** 1. row *************************** File: mysql-bin.000002 Position: 107 Binlog_Do_DB: test Binlog_Ignore_DB: mysql 1 row in set (0.00 sec)
③ 从my.cnf的配置
[root@localhost ~]# cat /etc/my.cnf [mysqld] log-bin=mysql-bin server-id = 2 replicate-do-db=test replicate-ignore-db=mysql log-slave-updates sync_binlog=1 slave-net-timeout=10
④ 从库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: 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)
⑤ 验证同步
主库:
mysql> use test; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> 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)
从库:
mysql> use test; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed mysql> 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)
