 Posted: Wed Oct 04, 2006 2:02 am Post subject: [solved] MySQL Port 3306 nach außen freigeben? |
 |
|
Hallo Leute, weiß im Moment nicht mehr weiter..
Ich will einen Datenbankzugriff von außen (mit Hilfe von Borland Delphi  und der MySQL-C-API ) auf MySQL realisieren. User mit Leserechten etc. etc. habe ich schon in MySQL (mysql-4.1.21) eingerichtet. Leider bekomme ich auch schon im internen Netzwerk keinen Connect ("Can't connect to MySQL-Server, error 10061").
Es scheint so, als sei der Port nicht richtig offen. Habe mal testweise in meinem Router den MySQL Port 3306 auf meinen Gentoo Server geöffnet, um dann von außen einen Portscan durchzuführen (http://www.heise.de/security/dienste/portscan/).
Dieser meldet aber: "3306 mysql geschlossen". Auch ein lokaler Portscanner auf dem Windows-Rechner im lokalen Netz zeigt den Port 3306 nicht als offen an.
Die "skip-networking" Option habe ich schon in der my.cnf auskommentiert. Hier trotzdem mal die my.cnf:
| Code: | # /etc/mysql/my.cnf: The global mysql configuration file.
# $Header: /var/cvsroot/gentoo-x86/dev-db/mysql/files/my.cnf-4.1,v 1.3 2006/05/05 19:51:40 chtekk Exp $

und hier die Ausgabe von "netstat":
| Code: | hannibal ~ # netstat -an | grep LISTEN
...
tcp 0 0 127.0.0.1:3306 0.0.0.0:* LISTEN
...
unix 2 [ ACC ] STREAM LISTENING 8275 /dev/log
unix 2 [ ACC ] STREAM LISTENING 18228 /var/run/cgisock
unix 2 [ ACC ] STREAM LISTENING 12683 /var/run/clamav/clamd-socket
unix 2 [ ACC ] STREAM LISTENING 34179 /var/run/mysqld/mysqld.sock
|
Also ist laut netstat der Port offen. Bekomme aber definitiv so keine Connection hin.
Hat jemand fixe Ideen? Dann raus damit

 sorry Leute, lesen bildet 
Einfach mysql nicht an localhost binden, sondern an eine bestimmte Adresse oder einfach ganz auskommentieren:
| Code: | | #bind-address = 127.0.0.1 |
Ich danke euch trotzdem, und hoffe, dass es trotz allem noch dem ein oder anderen hilft. |

| Du solltest den threat noch auf "[solved]" setzen. |
