一、 问题描述：
    查看从库状态时发现Last_SQL_Errno: 1062（主键值重复，入库失败）
具体错误如下：
Last_SQL_Errno: 1062
Last_SQL_Error: Error 'Duplicate entry '95' for key 'PRIMARY'' on query. Default database: 'nobserver_new'. Query: 'INSERT INTO media_class_jieliang (
    dateline,
    media_class,
    a_times,
    m_times
) SELECT
    DATE_FORMAT(adddate(now() ,- 1), '%Y%m%d'),
    IFNULL(
    c.media_class,
    '其他网站'
    ),
    sum(a.fld_atimes),
    sum(a.fld_mtimes)
FROM
    (
        SELECT
            fld_MediaID,
            fld_ATimes,
            fld_MTimes
        FROM
            tab_jieliang
        WHERE
            DATE_FORMAT(fld_AccessDate, '%Y%m%d') = DATE_FORMAT(adddate(now() ,- 1), '%Y%m%d')
    ) a
LEFT OUTER JOIN (
    SELECT
        fld_id,
        fld_Domain
    FROM
        tab_media
) b ON (a.fld_mediaid = b.fld_id)
LEFT OUTER JOIN (
    SELECT
        media_domain,
        media_class
    FROM
        tab_media_category
) c ON (
    b.fld_domain = c.media_domain
)
GROUP BY
    media_class'

二、解决方法：
1、主库查看media_class_jieliang表中id为95的值
mysql> select * from media_class_jieliang where seqid='95';
+-------+----------+-------------+---------+---------+
| seqid | dateline | media_class | a_times | m_times |
+-------+----------+-------------+---------+---------+
| 95 | 20150612 | ??θ? | 12 | 12 |
+-------+----------+-------------+---------+---------+
mysql> set names utf8;
mysql> select * from media_class_jieliang where seqid='95';
+-------+----------+-------------+---------+---------+
| seqid | dateline | media_class | a_times | m_times |
+-------+----------+-------------+---------+---------+
| 95 | 20150612 | 视频网站 | 12 | 12 |
+-------+----------+-------------+---------+---------+
2、从库查看media_class_jieliang表中id为95的值
mysql> select * from media_class_jieliang where seqid='95';
+-------+----------+-------------+---------+---------+
| seqid | dateline | media_class | a_times | m_times |
+-------+----------+-------------+---------+---------+
| 95 | 20150611 | ??θ? | 49 | 49 |
+-------+----------+-------------+---------+---------+
mysql> set names utf8;
mysql> select * from media_class_jieliang where seqid='95';
+-------+----------+-------------+---------+---------+
| seqid | dateline | media_class | a_times | m_times |
+-------+----------+-------------+---------+---------+
| 95 | 20150611 | 视频网站 | 49 | 49 |
+-------+----------+-------------+---------+---------+
3、从库与主库中的数据不一致，手工将从库数据更新
mysql> desc media_class_jieliang;
+-------------+-------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-------------+-------------+------+-----+---------+----------------+
| seqid | int(16) | NO | PRI | NULL | auto_increment |
| dateline | varchar(10) | NO | | NULL | |
| media_class | varchar(50) | NO | | NULL | |
| a_times | int(16) | NO | | 0 | |
| m_times | int(16) | NO | | 0 | |
+-------------+-------------+------+-----+---------+----------------+
mysql> replace into media_class_jieliang(seqid,dateline,media_class,a_times,m_times) values(95,'20150612','视频网站',12,12);
4、检查更新结果
mysql> select * from media_class_jieliang where seqid='95';
+-------+----------+-------------+---------+---------+
| seqid | dateline | media_class | a_times | m_times |
+-------+----------+-------------+---------+---------+
| 95 | 20150612 | 视频网站 | 12 | 12 |
+-------+----------+-------------+---------+---------+
5、停止从库服务，跳过该错误，启动从库服务
mysql> slave stop;
mysql> SET GLOBAL SQL_SLAVE_SKIP_COUNTER =1;
mysql> slave start;
6、检查从库同步状态
mysql> show slave status \G;
