1.load數據遇到報錯1
mysql> load data infile "/root/mysql_test/mysql_t1data" into table t1;
ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement
mysql>secure_file_priv參數用於限制LOAD DATA, SELECT …OUTFILE, LOAD_FILE()傳到哪個指定目錄。
secure_file_priv 爲 NULL 時，表示限制mysqld不允許導入或導出。
secure_file_priv 爲 /tmp 時，表示限制mysqld只能在/tmp目錄中執行導入導出，其他目錄不能執行。
secure_file_priv 沒有值時，表示不限制mysqld在任意目錄的導入導出。
查看現在的配置
mysql> show global variables like '%secure_file_priv%';
+------------------+-----------------------+
| Variable_name | Value |
+------------------+-----------------------+
| secure_file_priv | /var/lib/mysql-files/ |
+------------------+-----------------------+
1 row in set (0.00 sec)不能直接修改
mysql> set global secure_file_priv='';
ERROR 1238 (HY000): Variable 'secure_file_priv' is a read only variable
mysql>打開my.cnf，加入以下語句後重啓mysql。
secure_file_priv=''
重啓後進去查看
mysql> show global variables like '%secure_file_priv%';
+------------------+-------+
| Variable_name | Value |
+------------------+-------+
| secure_file_priv | |

[root@k8s-node3 mysql_test]#權限都改好了還是不對

網上查找資料發現mysql默認設置了使用/tmp作爲臨時讀寫目錄
檢索見下
