突然遇到mysql错误：ERROR 29 (HY000): File ‘/var/www/upload/*.txt’ not found (Errcode: 13)

上传后的文件都在本地,没有理由找不到,于是百度之,发现可能是ubuntu的文件存取权限问题.

但是当我把目录和文件权限都chmod为777后还是出错，google了后发现： Recent Ubuntu Server Editions (such as 10.04) ship with AppArmor and MySQL’s profile might be in enforcing mode by default. You can check this by executing

sudo aa-status like so:

# sudo aa-status 5 profiles are loaded.5 profiles are in enforce mode./usr/lib/connman/scripts/dhclient-script /sbin/dhclient3 /usr/sbin/tcpdump /usr/lib/NetworkManager/nm-dhcp-client.action /usr/sbin/mysqld 0 profiles are in complain mode.1 processes have profiles defined.1 processes are in enforce mode :/usr/sbin/mysqld (1089)0 processes are in complain mode.

If mysqld is included in enforce mode, then it is the one probably denying the write. Entries would also be written in /var/log/messages when AppArmor blocks the writes/accesses. What you can do is edit /etc/apparmor.d/usr.sbin.mysqld and add /data/ and /data/* near the bottom like so:

...
/usr/sbin/mysqld {
...
/var/log/mysql/ r,
/var/log/mysql/* rw,
/var/run/mysqld/mysqld.pid w,
/var/run/mysqld/mysqld.sock w,
/data/ r,
/data/* rw,
}

And then make AppArmor reload the profiles.

# sudo /etc/init.d/apparmor reload

大体内容就是，mysqld强制编码了，文件没有写入权限，于是我把该文件目录也加到mysqld(/etc/apparmor.d/usr.sbin.mysqld这个文件的底部，如上粗体部分):

/var/www/upload/import/ r,

/var/www/upload/import/* rw,
