基于MySQL Master Slave同步配置的操作分析

这篇文章主要为大家详细介绍了基于MySQL Master Slave同步配置的操作分析，具有一定的参考价值，可以用来参考一下。

感兴趣的小伙伴，下面一起跟随四海网的小编小韵来看看吧！

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 status\G;
 *************************** 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;
