mysql服务器主从同步设置

1、说明
   主服务器：192.168.0.17  
   从服务器：192.168.0.68   新建的一个从服务器，需要同步主服务器数据。
2、配置
   (1)、主服务器配置192.168.0.17
       #vim /etc/my.cnf      加入以下几行。
       server-id = 1105161846
       log-bin=mysql-bin
       log_bin_index = mysql-bin.index
       binlog_do_db = test_db
       sync_binlog = 1
      
       重启mysql服务
       #/etc/init.d/mysqld restart
       #mysql -uroot -p
       mysql>show master status;
       +------------------+----------+--------------+------------------+
       | File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |
       +------------------+----------+--------------+------------------+
       | mysql-bin.000038 | 32430008 | test_db      |                  |
       +------------------+----------+--------------+------------------+
       1 row in set (0.00 sec)

       创建复制账号

       mysql>GRANT REPLICATION SLAVE ON *.* TO 'repluser'@'192.168.0.68' IDENTIFIED BY "123456"; 
       mysql>flush privileges;

   (2)、从服务器配置192.168.0.68

        #vim /etc/my.cnf  加入以下几行。
        log-bin=mysql-bin
        log_bin_index       = mysql-bin.index
        log_slave_updates
        relay_log           = mysql-relay-bin
        relay_log_index     = mysql-relay-bin.index
        max_binlog_size     = 200M
        slave-skip-errors   = 1062,1053
        skip_slave_start    = 1
        expire_logs_days    = 7
        sync_binlog         = 100      

        把主数据库的db导入从数据库

        #mysqldump -h192.168.0.17 -u test_db -p ‘123456’ -R --triggers  --single-transaction --flush-logs --default-character-set=utf8 --master-data --database test_db > test_db.sql        
        #mysql -uroot -p -e "source < ~/test_db.sql"

        设置同步
 

        #mysql -uroot -p
        mysql>GRANT REPLICATION SLAVE ON *.* TO 'repluser'@'192.168.0.17' IDENTIFIED BY "123456";
        mysql> CHANGE MASTER TO MASTER_HOST='192.168.0.17',
            -> MASTER_PORT=3306,
            -> MASTER_USER='repluser',
            -> MASTER_PASSWORD='123456',
            -> MASTER_LOG_FILE='mysql-bin.000038',
            -> MASTER_LOG_POS=32430008;
        mysql>slave start;
        mysql>show slave status\G;
        .......
              Master_Log_File: mysql-bin.000038
          Read_Master_Log_Pos: 37762194
               Relay_Log_File: mysql-relay-bin.000004
                Relay_Log_Pos: 25417693
        Relay_Master_Log_File: mysql-bin.000038
             Slave_IO_Running: Yes
            Slave_SQL_Running: Yes
        ........
