mysql主从复制错误：Last_SQL_Error: Error #39;Duplicate entry #39;327#39; for key #39;PRIMARY#39;#39; ...
这个算不算解决，我都不太清楚，因为我感觉网上的说法，只是把错误忽略了，不表示以后用从库时不会出问题！！！
解决的办法是在从库上执行:
mysql> slave stop; mysql> set GLOBAL SQL_SLAVE_SKIP_COUNTER=1; mysql> slave start;上面的方法可以解决问题，还有一种解决问题的办法是通过修改mysql的配置文件，让从库的同步线程忽略这个错误，方法：
修改mysql配置文件 /etc/my.cnf 在 [mysqld]下加一行 slave_skip_errors = 1062 ,保存.重启mysql. mysql slave可以正常同步了.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
专业点的是以下这个：
线上环境我从来没有碰到过1062的问题，测试环境开发环境不停的出现类似问题，以往为了赶时间都是skip或者直接重新做，这会有时间，就好好去查查问题所在。

+---------+--------+-----------------------------------------+---------------------+----------------------------------+-------------+------------------------------------------+------+-----------+
2 rows in set (0.00 sec)
4 看binlog，在Relay_Master_Log_File: mysql-bin.000152，去主库找这个binlog解析出来
解析
[root@xxxx0402 tmp]# mysqlbinlog mysql-bin.000152 > a152.log
搜索包含'rding'字符串的语句，因为这个是主键字段之一，所以检索起来应该比较容易。
[root@xxxx0402 tmp]# grep a152.log 'rding' > rd.log
grep: rding: No such file or directory
[root@xxxx0402 tmp]# grep 'rding' a152.log > rd.log
[root@xxxx0402 tmp]# ll
[root@xxxx0402 tmp]# more rd.log
INSERT INTO `DATABASECHANGELOG` (`DATEEXECUTED`, `AUTHOR`, `xxxx`, `DESCRIPTION`, `COMMENTS`, `MD5SUM`, `ID`, `FILENAME`) VALUES (NOW(), 'rding', '1.9.3', 'Custom
SQL', '', '4ac9fbf5222bc344362ccdecbc072', '250.1.1', 'changelogs/myIDENTITY/250/xxxx.xml')
INSERT INTO `DATABASECHANGELOG` (`DATEEXECUTED`, `AUTHOR`, `xxxx`, `DESCRIPTION`, `COMMENTS`, `MD5SUM`, `ID`, `FILENAME`) VALUES (NOW(), 'rding', '1.9.3', 'Custom
SQL', 'Create new table for email change record', '8463e1cf4ba029e3ace675d3e69a71d2', '250.1.2', 'changelogs/myIDENTITY/250/xxxx.xml')
主库上面只有一条insert sql语句。
5 再去看从库的relay log日志Relay_Log_File: mysql-relay-bin.000455
[root@eanshlt2mydbc004db002 data]# cp mysql-relay-bin.000455 /tmp
[root@eanshlt2mydbc004db002 data]# cd /tmp
[root@eanshlt2mydbc004db002 tmp]# mysqlbinlog mysql-relay-bin.000455 > relay.log
[root@eanshlt2mydbc004db002 tmp]#
[root@eanshlt2mydbc004db002 tmp]# grep 'rding' relay.log > rd.log
[root@eanshlt2mydbc004db002 tmp]# more rd.log
INSERT INTO `DATABASECHANGELOG` (`DATEEXECUTED`, `AUTHOR`, `xxxx`, `DESCRIPTION`, `COMMENTS`, `MD5SUM`, `ID`, `FILENAME`) VALUES (NOW(), 'rding', '1.9.3', 'Custom
SQL', '', '4ac9fbf5222bc344362ccdecbc072', '250.1.1', 'changelogs/myIDENTITY/250/xxxx.xml')
INSERT INTO `DATABASECHANGELOG` (`DATEEXECUTED`, `AUTHOR`, `xxxx`, `DESCRIPTION`, `COMMENTS`, `MD5SUM`, `ID`, `FILENAME`) VALUES (NOW(), 'rding', '1.9.3', 'Custom
SQL', 'Create new table for email change record', '8463e1cf4ba029e3ace675d3e69a71d2', '250.1.2', 'changelogs/myIDENTITY/250/xxxx.xml')
奇怪了，2边的都是一样子的。这个错误怎么判断？
6 去看下主从关于这个数据记录的录入时间。
从库上面：
mysql> select * from DATABASECHANGELOG where AUTHOR='rding' and ID='250.1.1' and FILENAME='changelogs/myIDENTITY/250/xxxx.xml'\G;
*************************** 1. row ***************************

主库上面 ：
mysql> select * from DATABASECHANGELOG where AUTHOR='rding' and ID='250.1.1' and FILENAME='changelogs/myIDENTITY/250/xxxx.xml'\G;
*************************** 1. row ***************************

DESCRIPTION: Custom SQL
COMMENTS:
TAG: NULL
xxxx: 1.9.3
1 row in set (0.02 sec)
ERROR:

mysql>
看DATEEXECUTED时间字段都是8月12日录入的，可惜我的db server由于磁盘有限，只保存了近期的binlog，而且现在主库上面最早的binlog就是出错的那个mysql-bin.000152
7 最后一招，去看从库的binlog，看是否近期有人insert了这条记录
[root@eanshlt2mydbc004db002 data]# cp mysql-bin.004* /tmp/
[root@eanshlt2mydbc004db002 tmp]# mysqlbinlog mysql-bin.004268 > 1.log
[root@eanshlt2mydbc004db002 tmp]# grep 'rding' 1.log > rd1.log
[root@eanshlt2mydbc004db002 tmp]# ll rd1.log
-rw-r--r-- 1 root root 0 Sep 3 17:47 rd1.log
空的，第一个日志没有录入操作
[root@eanshlt2mydbc004db002 tmp]# mysqlbinlog mysql-bin.004269 > 2.log
[root@eanshlt2mydbc004db002 tmp]# grep 'rding' 2.log > rd2.log
[root@eanshlt2mydbc004db002 tmp]# ll rd2.log
-rw-r--r-- 1 root root 0 Sep 3 17:48 rd2.log
[root@eanshlt2mydbc004db002 tmp]#
空的，第二个日志没有录入操作
[root@eanshlt2mydbc004db002 tmp]# mysqlbinlog mysql-bin.004270 > 3.log
[root@eanshlt2mydbc004db002 tmp]# grep 'rding' 3.log > rd3.log
[root@eanshlt2mydbc004db002 tmp]# ll rd3.log
-rw-r--r-- 1 root root 0 Sep 3 17:49 rd3.log
[root@eanshlt2mydbc004db002 tmp]#
空的，第三个日志没有录入操作
[root@eanshlt2mydbc004db002 tmp]# mysqlbinlog mysql-bin.004271 > 4.log
ERROR: Error in Log_event::read_log_event(): 'read error', data_len: 438, event_type: 2
[root@eanshlt2mydbc004db002 tmp]# grep 'rding' 4.log > rd4.log
[root@eanshlt2mydbc004db002 tmp]# ll rd4.log
-rw-r--r-- 1 root root 0 Sep 3 17:50 rd4.log
空的，第四个日志没有录入操作
这里解析报错了，解决方案，记录在如此
http://blog.csdn.net/mchdba/article/details/11011229
[root@eanshlt2mydbc004db002 tmp]# mysqlbinlog mysql-bin.004272 > 5.log
[root@eanshlt2mydbc004db002 tmp]# grep 'rding' 5.log > rd5.log
[root@eanshlt2mydbc004db002 tmp]# ll rd5.log
-rw-r--r-- 1 root root 0 Sep 3 18:07 rd5.log
[root@eanshlt2mydbc004db002 tmp]#
空的，第五个日志没有录入操作
解析了从库的5个日志，都没有看到这条纪律的insert操作，问题到此卡住了，原因何在？这边开发的兄弟们已经在催了，我只要skip之后从库重新做了。
