先看下，log_bin_trust_function_creators有没有开启
mysql> show variables like '%func%';
+---------------------------------+-------+
| Variable_name | Value |
+---------------------------------+-------+
| log_bin_trust_function_creators | OFF |
+---------------------------------+-------+
1 row in set (0.00 sec)
如果Value处值为OFF，则需将其开启。
mysql> set global log_bin_trust_function_creators=1;
Query OK, 0 rows affected (0.00 sec)
mysql> show variables like '%func%';
+---------------------------------+-------+
| Variable_name | Value |
+---------------------------------+-------+
| log_bin_trust_function_creators | ON |
+---------------------------------+-------+
1 row in set (0.00 sec)
