环境为rhel6，在root下操作：
select * into outfile '/root/aaa/tbl.txt'
fields terminated by ',' optionally enclosed by '"'
lines terminated by '\n'
from tbl;显示错误为：ERROR 1 (HY000) at line 1: Can't create/write to file '/root/aaa/tbl.txt' (Errcode: 13)但是导入到/tmp目录是成功的。尝试将aaa目录的权限改为1777，但仍然无效。
不会只能是mysql安装用户下的目录或/tmp吧？

父目录和子目录的权限应该没有继承关系吧？/root/aaa目录是777，但/root不是。
