各位用户为了找寻关于基于MySQL Master Slave同步配置的操作详解的资料费劲了很多周折。这里教程网为您整理了关于基于MySQL Master Slave同步配置的操作详解的相关资料，仅供查阅，以下为您介绍关于基于MySQL Master Slave同步配置的操作详解的详细内容
环境： PC：ubuntu 10.10 192.168.1.112（master） 192.168.10.245（slave） MySQL : 5.1.49-1ubuntu8.1-log 在master中已经存在数据库test 首先修改mysql配置文件：/etc/mysql/my.cnf [master] #author:zhxia
代码如下:
#master 同步设置 server-id = 1 log_bin = /var/log/mysql/mysql-test-bin.log expire_logs_days = 10 max_binlog_size = 100M binlog_format =mixed
[slave] #author:zhxia
代码如下:
server-id = 2 replicate-do-db=test replicate-do-db=blog log_bin = /var/log/mysql/mysql-bin.log relay_log =/var/log/mysql/mysql-relay-bin.log expire_logs_days = 10 max_binlog_size = 100M #binlog_do_db = test #binlog_ignore_db = include_database_name binlog_format = mixed slave-net-timeout=6012 master-connect-retry=10
接着在master上创建备份帐号
代码如下:
grant replication slave,replication client on *.* to 'slave'@'192.168.10.245' identified by '123456';
将master中的数据库 导入到slave中， 先锁表，禁止写入操作 flush tables with read lock; 先从master导出：mysqldump -uroot -p test > /tmp/test.sql 再导入到slave： mysql -uroot -p test < /tmp/test.sql ,记得需要先建库test 进入master上的mysql,查看master状态 #author:zhxia
代码如下:
mysql> show master status; +-----------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | +-----------------------+----------+--------------+------------------+ | mysql-test-bin.000022 | 624 | | | +-----------------------+----------+--------------+------------------+ 1 row in set (0.02 sec)
进入slave上的Mysql #author:zhxia
代码如下:
change master to master_host='192.168.1.112', master_user='slave', master_password='123456', master_log_file='mysql-test-bin.000022', master_log_pos=106;
然后启动salve，并查看状态： #author:zhxia
代码如下:
start slave; mysql> show slave statusG; *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 192.168.1.112 Master_User: slave Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-test-bin.000022 Read_Master_Log_Pos: 624 Relay_Log_File: mysql-relay-bin.000005 Relay_Log_Pos: 533 Relay_Master_Log_File: mysql-test-bin.000022 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: test,blog 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: 624 Relay_Log_Space: 688 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: 1 row in set (0.00 sec) ERROR: No query specified
最后将master上的表解锁 unlock tables;
