canal传递过来的bin-log会丢失

1、开启bin-log，路径要设置在mysql用户所属文件夹下
例如：
log-bin=/home/123/bin-log 123的所属用户就要是Mysql
[root@520 home]# ll
总计 163736
drwxr-xr-x 2 mysql mysql 4096 01-16 16:47 123

140116 15:59:21 mysqld started

140116 15:59:22 mysqld ended
或者
140116 16:17:06 mysqld started
140116 16:17:06 [Warning] option 'max_join_size': unsigned value 18446744073709551615 adjusted to 4294967295

这种报错有可能是设置bin-log日志路径时，没有指定在Mysql所属用户的目录下。
也有另外一种可能是：

mysql> select @@max_join_size;
+-----------------+
| @@max_join_size |
+-----------------+
| 705032704 |
+-----------------+
1 row in set (0.00 sec)
mysql> SET sql_max_join_size=4294967295;
Query OK, 0 rows affected (0.00 sec)

设置了max_join_size参数，当然，一般来说这个参数的默

虽然我很聪明，但这么说真的难到我了
