mysql load data遇到的两个错误和解决方法

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参数用于限制LOAD DATA, SELECT …OUTFILE, LOAD_FILE()传到哪个指定目录。

secure_file_priv 为 NULL 时，表示限制mysqld不允许导入或导出。
secure_file_priv 为 /tmp 时，表示限制mysqld只能在/tmp目录中执行导入导出，其他目录不能执行。
secure_file_priv 没有值时，表示不限制mysqld在任意目录的导入导出。

查看现在的配置

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>

打开my.cnf，加入以下语句后重启mysql。
secure_file_priv=‘‘

重启后进去查看

mysql> show global variables like ‘%secure_file_priv%‘;
+------------------+-------+
| Variable_name? ? | Value |
+------------------+-------+
| secure_file_priv |? ? ?? |
+------------------+-------+
1 row in set (0.02 sec)

2.load数据遇到报错2

mysql> load data infile "/root/mysql_test/mysql_t1data" into table t1;
ERROR 13 (HY000): Can‘t get stat of ‘/root/mysql_test/mysql_t1data‘ (OS errno 13 - Permission denied)
mysql>

检索下数据目录在哪

mysql> show variables like ‘%datadir%‘;
+---------------+-----------------+
| Variable_name | Value? ? ? ? ?? |
+---------------+-----------------+
| datadir? ? ?? | /var/lib/mysql/ |
+---------------+-----------------+
1 row in set (0.03 sec)

mysql>

检查下这个目录的权限情况

[root@k8s-node3 mysql_test]# ll /var/lib/mysql
total 168048
-rw-r----- 1 mysql mysql? ? ?? 56 Nov 26 03:22 auto.cnf
-rw-r----- 1 mysql mysql? ? ? 178 Nov 26 03:49 binlog.000001
-rw-r----- 1 mysql mysql? ? ? 661 Nov 26 04:49 binlog.000002
-rw-r----- 1 mysql mysql? ? ? 155 Nov 27 01:30 binlog.000003
-rw-r----- 1 mysql mysql? ? ? 178 Nov 27 03:03 binlog.000004
-rw-r----- 1 mysql mysql? ? ? 178 Nov 27 03:03 binlog.000005
-rw-r----- 1 mysql mysql? ? ? 178 Nov 27 03:07 binlog.000006

在看看
/root/mysql_test/mysql_t1data
的权限情况

[root@k8s-node3 mysql_test]# ll
total 8
-rw-r--r-- 1 root root 117 Dec 13 02:09 mysql_t1
-rw-r--r-- 1 root root? 28 Dec 13 02:10 mysql_t1data
[root@k8s-node3 mysql_test]#

修改权限看看
[root@k8s-node3 mysql_test]# chmod 777 *
[root@k8s-node3 mysql_test]# ll
total 8
-rwxrwxrwx 1 root root 117 Dec 13 02:09 mysql_t1
-rwxrwxrwx 1 root root? 28 Dec 13 02:10 mysql_t1data
[root@k8s-node3 mysql_test]#

权限都改好了还是不对
mysql> load data infile ‘/root/mysql_test/mysql_t1data‘ into table t1;
ERROR 13 (HY000): Can‘t get stat of ‘/root/mysql_test/mysql_t1data‘ (OS errno 13 - Permission denied)
mysql>

网上查找资料发现mysql默认设置了使用/tmp作为临时读写目录
检索见下

mysql> show variables like ‘%tmp%‘;
+----------------------------------+-----------+
| Variable_name? ? ? ? ? ? ? ? ? ? | Value? ?? |
+----------------------------------+-----------+
| default_tmp_storage_engine? ? ?? | InnoDB? ? |
| innodb_tmpdir? ? ? ? ? ? ? ? ? ? |? ? ? ? ?? |
| internal_tmp_disk_storage_engine | InnoDB? ? |
| internal_tmp_mem_storage_engine? | TempTable |
| slave_load_tmpdir? ? ? ? ? ? ? ? | /tmp? ? ? |
| tmp_table_size? ? ? ? ? ? ? ? ?? | 16777216? |
| tmpdir? ? ? ? ? ? ? ? ? ? ? ? ?? | /tmp? ? ? |
+----------------------------------+-----------+
7 rows in set (0.00 sec)

mysql>

把文件移到/tmp目录下试试

[root@k8s-node3 ~]# mv mysql_test/ /tmp
[root@k8s-node3 ~]# ll /tmp/mysql_test/
total 8
-rwxrwxrwx 1 mysql mysql 117 Dec 13 02:09 mysql_t1
-rwxrwxrwx 1 mysql mysql? 28 Dec 13 02:10 mysql_t1data
[root@k8s-node3 ~]#

再load看看

mysql> load data infile ‘/tmp/mysql_test/mysql_t1data‘ into table t1;
ERROR 1261 (01000): Row 1 doesn‘t contain data for all columns
mysql>

成功了。这个错误是别的问题了。
下一个问题来处理
