今天在學習MySQL時候，想要將文本文件的數據導入到數據庫中，卻發現一直報錯，換了導入文本的路徑也還是同樣的錯誤，錯誤顯示ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement。
select ......into outfile 是一種邏輯備份方法，它的恢復速度非常之快，比insert的插入速度還要快。它只能備份表中的數據，並不能包含表的結構。
然后在網上找解決辦法，找的方法在Linux 下也不怎么好用，最后找到了解決Linux下MySQL文件導入出錯的方法
出錯的原因是因為在MySQL 5.7.6版本之后，導入文件只能在secure_file_priv指定的文件夾下（也有原因是因為權限不夠）
方法一：
我們可以用show variables like '%secure%';命令顯示文件目錄
這樣將導入文件放在 /var/lib/mysql-files/文件夾下，之后再從這里導入就可以了
導出文件時候，也是將 文件導出到這個文件夾里。
root@localhost:mysql3306.sock [(none)]>show global variables like '%secure%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| require_secure_transport | OFF |
| secure_auth | ON |
| secure_file_priv | /data/mysql/mysql3306/tmp/ |
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
root@localhost:mysql3306.sock [(none)]>select * from qt into outfile '/data/mysql/mysql3306/tmp/qt.sql';

恢復：

You can turn off this feature to get a quicker startup with -A

如果顯示ERROR 1261 (01000): Row 1 doesn't contain data for all columns
這個錯誤，是因為數據行不匹配，默認不能有空，用下列命令解決set sql_modul = 0;
