Bekanntes MySQL-Server Permissionproblem

[nasi]

Hallo,

ich habe wie auch viele andere ein Problem mit den Rechten von MySQL. SObald ich den Server starten will kommt:

Code: Select all

 mysqld: Can't read dir of '/tmp/' (Errcode: 13)
070604 12:43:19 [ERROR] Can't start server : Bind on unix socket: Permission denied
070604 12:43:19 [ERROR] Do you already have another mysqld server running on socket: /var/run/mysqld/mysqld.sock ?
070604 12:43:19 [ERROR] Aborting

070604 12:43:19 [Note] mysqld: Herunterfahren beendet

Ich habe bereits Rechte gesetzt und alles erdenklich mögliche und wa sim Internet seit einem Monat zu finden ist versucht, leider alles ohne Erfolg. Ich bewege mich kein Stück von der Stelle.

System: Debian 4.0 Etch
MySQL: mysqld Ver 5.0.32-Debian_7etch1-log for pc-linux-gnu on i486
Kernel: 2.6.18-4-486
Zugriff: remote/ ssh only


Kurzer Auszug ausm syslog:

Ich hoffe ich hab alle nötigen Informationen gepostet. Bin für jeden Tipp dankbar!

[lord_pinhead]

Hast du /tmp vielleicht falsch gemountet oder ist das gar nicht gemountet?

[flo]

Code: Select all

mount

und

Code: Select all

df -h

bitte - alternativ gib ihm doch mal ein anderes tmp-Verzeichnis und schau, ob er dann startet, bitte schau nach dem herunterfahren auch noch, ob wirklich alle mysql-Prozesse weg sind.

[nasi]

Schonmal vielen Dank für eure Tipps, ich hab se mir direkt mal zu Herzen genommen und "/tmp/" auf eine eigene Partition gelegt und es nochmals getestet.

Code: Select all

content:/# mount
/dev/hda2 on / type ext3 (rw,errors=remount-ro,usrquota)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)

sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
procbususb on /proc/bus/usb type usbfs (rw)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)

Code: Select all

drwxrwxrwt  2 root  root         1024 2007-06-05 12:12 tmp

Aber leider der gleiche Fehler wie sonst auch, Errcode 13 ... "Can`t read dir of "/tmp/"


Zu den Prozessen:

Code: Select all

content:/# ps aux | grep mysql
root     16206  0.0  0.1   2024   736 pts/1    R+   12:22   0:00 grep mysql

Code: Select all

content:/# find / -name *pid | grep mysql
/usr/bin/mysql_waitpid
/root/mysql-5.0.41-linux-i686-glibc23/bin/mysql_waitpid

Nix da :(

Hab grad nochma was getestet ... Es scheint ein allgemeines Problem mit dem "mysql" User zu sein wenn ich das richtig interpretiere ...

Code: Select all

Stimmen alle Pfade in der my.cnf? Mal mit /var/tmp statt /tmp versucht?

Code: Select all

ls -alh /var/{lib,log}/mysql*

*schäääm* Da muss ich grad leider mal passen ... Das übersteigt meine Linuxkompetenzen :(
