[gelöst] XAMPP mySQL startet nach Computercrash nicht

Postby mp1975 » 22. September 2012 19:48

hallo

hab ein "kleines" problem mysql unter xampp, windows 7 64kbit zum laufen zu bekommen

xampp version 1.7.3

folgendes problem: ich habe dummerweise die aktuelle xampp version über die alte drüber installiert und das gab dann einige probleme, hab aber vorher das xampp verzeichnis weg gesichert. bei der neuen version hat sich die mySQL DB nicht starten lassen, also hab ich wieder downgegraded und hab den neuen ordner umbenannt und den alten wieder auf seinen platz gestellt. hab an diesem tag auch noch ein programm installiert, dass den IIS installiert hat - nur zur info.
jedenfalls ist jetzt das problem, dass apache startet, aber mysql es nicht mehr tut. wenn ich xampp total neu installiere funktioniert beides, nur brauche ich die datenbanken der alten installation + user. hab dann versucht in die neue installation den ordner einer DB reinzukupieren, da hat er mir die datenbank angezeigt und auch mit der richtigen anzahl der tables, aber wenn ich auf die DB geklickt habe, hat mir phpmyadmin gesagt, dass keine tables vorhanden sind.

my.ini

# This is for a system with little memory (32M - 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with

# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# Don't listen on a TCP/IP port at all. This can be a security enhancement,

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     = <port>
#
# binary logging - not required for slaves, but recommended
#log-bin         = mysql-bin

hallo nochmal

hab jetzt nach 2 tagen suchen und ausprobieren eine lösung in einem forum gefunden und die antwort ist folgende:

You should be able to stop mysql, move all your old folders from data, except mysql, and including any ibdata files to your new data folder, (not ib_logfiles), and then start mysql server. All your old data should now be there.

also alte daten alle sichern
xampp neu installieren
vom backup alle ordner von mysql/data in die neue mysql installation in den ordner mysql/data kopieren AUSSER den "mysql" ordner und die "ib_logfiles"
mysql sollte man dann wieder starten können und die tables sollten auch wieder sichtbar sein
nun noch den user für die datenbank anlegen, denn der ist leider weg, aber das ist sicher das kleinste problem :)

ich hoffe die lösung hilft jemanden weiter

grüße
