ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement

centos7.5 使用into outfile备份失败

问题:

mysql>  select * from world.city into outfile '/tmp/world_city.data';
ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement

原因:

mysql> show variables like '%secure%';
+------------------+-------+
| Variable_name    | Value |
+------------------+-------+
| secure_auth      | ON    |
| secure_file_priv | NULL  |
+------------------+-------+
没有指定secure_file_priv位置

解决方法:

[root@db01-51 ~]# vim /etc/my.cnf
[mysqld]
secure_file_priv=/tmp	#指定secure_file_priv的位置
[root@db01-51 ~]# /etc/init.d/mysqld restart
mysql> select * from world.city into outfile '/tmp/world_city.data';
Query OK, 4079 rows affected (0.02 sec)

注意: select ......into outfile 是一种逻辑备份方法，它的恢复速度非常之快，比insert的插入速度还要快。它只能备份表中的数据，并不能包含表的结构。 一般不用它来做备份
