摘要：基于MySQL Master Slave同步配置的操作详解

[b]环境： [/b]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 [b]首先修改mysql配置文件：/etc/mysql/my.cnf [/b][master] [b]#author:zhxia [/b]

[u]复制代码[/u] 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] [b]#author:zhxia [/b]

[u]复制代码[/u] 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

[u]复制代码[/u] 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 [b]#author:zhxia [/b]

[u]复制代码[/u] 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 [b]#author:zhxia [/b]

[u]复制代码[/u] 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： [b]#author:zhxia [/b]

[u]复制代码[/u] 代码如下:

start slave;

 mysql> show slave status\G;
 *************************** 1. row ***************************
                Slave_IO_State: Waiting for master to send event
                   Master_Host: 192.168.1.112

               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

                    Last_Error:

           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;
