<a href="http://bugs.mysql.com/bug.php?id=60574">http://bugs.mysql.com/bug.php?id=60574</a> [<a href="http://bugs.mysql.com/bug.php?id=60574" target="_blank">^</a>]<br />
Bug report claims that affected versions are 5.1.50 and up. 5.1.49 and older should be OK.<br />
<br />
MySQL can not create temporary files in /tmp. It is same for ANY database!<br />
SELinux is disabled.<br />
I logged to mysql as root and error is same.<br />
<br />
[<a href="mailto:root@chiron">root@chiron</a> ~]# ls -lsahd /tmp<br />
4.0K drwxrwxrwt. 17 root root 4.0K Feb 13 20:55 /tmp<br />
<br />
There is enough space, and I successfully created files as root, mysql <br />
and plnet user (domain owner).<br />
<br />

I tested on cacti database and on 2 Joomla databases with same results.<br />
<br />
Database changed<br />
mysql> CREATE TEMPORARY TABLE IF NOT EXISTS plugin_temp_table LIKE jos_menu;<br />
ERROR 1004 (HY000): Can't create file '/tmp/#sql21f8_f3_1.frm' (errno: 9)<br />
mysql> CREATE TEMPORARY TABLE barney (SELECT * FROM jos_menu WHERE 1=0);<br />
Query OK, 0 rows affected (0.01 sec)<br />

mysql> CREATE TEMPORARY TABLE IF NOT EXISTS plugintest LIKE jos_menu;<br />
ERROR 1004 (HY000): Can't create file '/tmp/#sql21f8_f3_3.frm' (errno: 9)<br />
mysql> CREATE TEMPORARY TABLE IF NOT EXISTS barney LIKE jos_menu;<br />

<br />
Changed name of table to create produced result, but with warning.<br />
<br />
Seams "LIKE" is the problem.
