mysqlimport: Error: 3948, Loading local data is disabled; this must be enabled on both the client and server sides, when using table: user
 
# 解决方案：登录mysql，将local_infile设置为NO
[root@master data]# mysql -u root -p
Enter password: 
mysql> show global variables like 'local_infile';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| local_infile  | OFF   |

1 row in set (0.00 sec)
 
mysql> set global local_infile=1;
Query OK, 0 rows affected (0.00 sec)

• 使用ssh工具登录虚拟机服务器，登录mysql，导出为csv

# 报错如下，指定目录没有权限
mysql> select * from user into outfile '/home/data/user.csv' FIELDS TERMINATED BY ',';
ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement
 
# 查看有权限的目录
mysql> show global variables like '%secure_file_priv%';
+------------------+-----------------------+
| Variable_name    | Value                 |

# 再次测试，成功
mysql> select * from student into outfile '/var/lib/mysql-files/student.csv' FIELDS TERMINATED BY ',';
Query OK, 4 rows affected (0.00 sec)

• 本地安装mysql，使用本地mysql.exe将本地csv文件导入远程mysql

# 远程表中没有数据
 
# 本地进入user.csv所在文件夹，右键打开Git Bash
ychen@DESKTOP-49HGBQ1 MINGW64 /c/work
$ pwd
/c/work
ychen@DESKTOP-49HGBQ1 MINGW64 /c/work
$ ls
 user.csv
 
# 执行如下代码，导入成功
