I wrote a script to check the domain name and run it on my Ubuntu 8.04 Desktop machine. An error occurred while importing data to the Mysql database:

Mysql> load data infile "/home/cron/ddd.txt" into table test;
ERROR 29 (HY000): File '/home/cron/ddd.txt' not found (Errcode: 13)

The file exists and has the following permissions:

Alfa @ alfa-desktop :~ $ Ll/home/cron/ddd.txt
-Rwxrwxrwx 1 alfa 63825408/home/cron/ddd.txt

The permissions in the database are also given:

Strange,

I searched the internet and said it was like a BUG, but it could be solved:

Solution:

Gelmjw @ voyager :~ $ Sudo aa-complain/usr/sbin/mysqld
[Sudo] password for gelmjw:
Setting/usr/sbin/mysqld to complain mode.
Gelmjw @ voyager :~ $ Sudo/etc/init. d/apparmor reload
Reloading AppArmor profiles: done.
Gelmjw @ voyager :~ $

I don't know what the apparmor command is for. It's easy to run the two commands ..
