secure_file_priv參數(shù)說明:
這個參數(shù)用來限制數(shù)據(jù)導入和導出操作的效果,例如執(zhí)行LOAD DATA、SELECT ... INTO OUTFILE語句和LOAD_FILE()函數(shù)。這些操作需要用戶具有FILE權限。
1. 如果這個參數(shù)為空,這個變量沒有效果;
2. 如果這個參數(shù)設為一個目錄名,MySQL服務只允許在這個目錄中執(zhí)行文件的導入和導出操作。這個目錄必須存在,MyS
QL服務不會創(chuàng)建它;
3. 如果這個參數(shù)為NULL,MySQL服務會禁止導入和導出操作。這個參數(shù)在MySQL 5.7.6版本引入
secure_file_priv may be set as follows:
If empty, the variable has no effect. This is not a secure setting.
If set to the name of a directory, the server limits import and export operations to work only with files in that dire
ctory. The directory must exist; the server will not create it.
If set to NULL, the server disables import and export operations.
