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 status\G
