[root@potato Desktop]# mysqldump -uroot -proot -S /tmp/mysql.sock --tab=/data/mysql/mytest_3306/data/backup lala
mysqldump: Got error: 1290: The MySQL server is running with the --secure-file-priv option so it cannot execute this statement when executing 'SELECT INTO OUTFILE'
当secure_file_priv的值没有具体值时，表示不对mysqld 的导入|导出做限制
查看数据库当前该参数的值
root@localhost:mysql.sock 00:14:52 [(none)]>show global variables like '%secure%';
+------------------+-------+
| Variable_name | Value |
+------------------+-------+
| secure_auth | ON |
| secure_file_priv | NULL |
+------------------+-------+
2 rows in set (0.00 sec)
清楚地看到secure_file_priv 的值是NULL，说明此时限制导入导出的
所以应该改变该参数
可是查看了mysql.cnf中居然没有对这个参数进行设定，就说明这个参数默认便是null
所以再mysql.cnf中的[mysqld]加入secure_file_priv =
再重启mysql服务
然后再查一下此时参数的值
root@localhost:mysql.sock 00:28:30 [(none)]>show global variables like '%secure%';
+------------------+-------+
| Variable_name | Value |
+------------------+-------+
| secure_auth | ON |
| secure_file_priv | |
+------------------+-------+
2 rows in set (0.00 sec)
已经是我们要的结果
开始进行导出
[root@potato Desktop]# mysqldump -uroot -proot -S /tmp/mysql.sock --tab=/data/mysql/mytest_3306/data/backup lala

可以看到成功了
