Hi!"
Ja ne is klar werdet ihr sagen Ich meine aber:
Im PHP MyAdmin gibt es ja 'Laufzeitinformationen'. Diese sind für mich seit kurzem anlass, dass ich mich ein bisschen mit der Funktionsweise von MySQL genauer beschäftigen möchte.
Ich habe im Internet bisschen recherchiert und einige dinge ausprobiert. In laufzeitinformationen wird immer mit roten Zahlen gewarnt, wenn man sich um irgendwas kümmern möchte...
So habe ich dort schon einige engpässe auf meinem PC beheben können.
Jetzt habe ich allerdings folgendes Problem, dass ich nicht los werde:
Kann mir jemand helfen? Ich hab schon einige Configwerte ausprobiert, aber er schreibt immer die drei temporären Tables..
Ich hätte das gerne Festplattenschonender oder schneller. Habe 2 GB RAM;
Hier mal noch meine /etc/my.cnf:
Vielen Dank für Hilfe!

Jetzt habe ich allerdings folgendes Problem, dass ich nicht los werde:
Created_tmp_disk_tables 3 Anzahl der (implizit) auf der Platte erzeugten temporären Tabellen bei der Ausführung von Statements. Wenn Created_tmp_disk_tables hoch ist, sollten Sie eventuell die Variable tmp_table_size herauf setzen, damit temporäre Tabellen im Speicher erzeugt werden statt auf der Festplatte.
Kann mir jemand helfen? Ich hab schon einige Configwerte ausprobiert, aber er schreibt immer die drei temporären Tables..

# 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
# other programs (such as a web server)
#
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /var/lib/mysql) or
# ~/.my.cnf to set user-specific options.
#
# 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.
# The following options will be passed to all MySQL clients

# 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>
