mysql failed to start
 

hello...mysql cannot start.in the log error says:
/usr/libexec/mysqld: Can't create/write to file '/tmp/ibuheYgy' (Errcode: 28)
080724 4:32:00 InnoDB: Error: unable to create temporary file; errno: 28
080724 4:32:00 [ERROR] Can't start server : Bind on unix socket: No space left on device
080724 4:32:00 [ERROR] Do you already have another mysqld server running on socket: /var/lib/mysql/mysql.sock ?
080724 4:32:00 [ERROR] Aborting

080724 4:32:00 [Note] /usr/libexec/mysqld: Shutdown complete

080724 04:32:00 mysqld ended

the answer is there mysql can not write to /tmp
it dose not have the right permissions
did you create a new user called mysql at time of install ?
and is /tmp/ibuheYgy file owned by mysql
see
http://dev.mysql.com/doc/refman/4.1/en/index.html
---------------------------
also it may have been running already

never mind..i reinstall my mysql.huhu

The answer was here:

080724 4:32:00 [ERROR] Can't start server : Bind on unix socket: No space left on device

whatever disk/ram partition your /tmp was on was full

Which means the reinstall is most likely to fail as well unless the OP clears out some space. Linux and it's applications are not like Windows. Reinstalls are always last options.
