mysql> select host,user from user where host<>‘localhost‘ into outfile ‘/root/aa.txt‘;
ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement
mysql> show variables like ‘%secure%‘; +--------------------------+-----------------------+
| Variable_name | Value |
+--------------------------+-----------------------+
| require_secure_transport | OFF |
| secure_auth | ON |
| secure_file_priv | /var/lib/mysql-files/ |
+--------------------------+-----------------------+
3 rows in set (0.00 sec)
发现secure_auth为on，可以导出，路径为/var/lib/mysql-files/
mysql> select host,user from user where host<>‘localhost‘ into outfile ‘/var/lib/mysql-files/test.txt‘;
Query OK, 3 rows affected (0.00 sec)
导出成功
