本篇内容主要讲解“mysql怎么同步一张表”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“mysql怎么同步一张表”吧!

1.主上修改my.cnf文件：（主上）
server-id=1?
log-bin=mysql-bin

2.从上修改配置文件 my.cnf（从上）
server-id=2
relay-log=replay-bin
read-only =1
replicate-ignore-db = mysql
replicate-ignore-db = test
replicate-ignore-db = information_schema
replicate-wild-do-table = gutest.a

3.创建同步的用户（主上）
GRANT REPLICATION SLAVE, REPLICATION CLIENT ON *.* to rep@'192.168.1.196' identified by 'rep';

4.在主要查询主的日志信息（主上）
flush tables with read lock;
show master status;
unlock tables;

5.同步到主库（从上）
stop slave;
reset slave;
CHANGE MASTER TO MASTER_HOST='192.168.1.195',MASTER_USER='rep',MASTER_PASSWORD='rep',MASTER_LOG_FILE='mysql-bin.000001',MASTER_LOG_POS=986; #986是上一个语句查询出来的日志号
start slave;

6.在从上验证：
mysql> show slave statusG
