s Hallo,

ich wollte das Datadir von mysql ändern (nach /drive/data/mysql).
Also habe ich die Änderungen an der /etc/my.cnf vorgenommen.


# Example MySQL config file for medium systems.
#
# 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
[client]
#password = your_password
port = 3306
socket = /drive/data/mysql/mysql.sock

# Here follows entries for some specific programs

# The MySQL server
[mysqld]
port = 3306
socket = /drive/data/mysql/mysql.sock
skip-locking
key_buffer = 16M
max_allowed_packet = 1M
table_cache = 64
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!
#
#skip-networking

# Replication Master Server (default)
# binary logging is required for replication
# log-bin

# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id = 1

# 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

# Point the following paths to different dedicated disks
#tmpdir = /tmp/
#log-update = /path-to-dedicated-directory/hostname

# Uncomment the following if you are using BDB tables

# Uncomment the following if you are using InnoDB tables

Wenn ich mysql nun starten werde kommt failed. In den logs steht folgendes:


050606 18:51:46 mysqld started
050606 18:51:46 [ERROR] Can't start server : Bind on unix socket: Permission denied
050606 18:51:46 [ERROR] Do you already have another mysqld server running on socket: /drive/data/mysql/mysql.sock ?

050606 18:51:46 [Note] /usr/sbin/mysqld: Shutdown complete

050606 18:51:46 mysqld ended


Habe den Ordner mit cp -p kopiert und ´die Berechtigungen mit ls -al geprüft, müsste stimmen. Was kanns noch sein? SuFu und google hat mir leider keine Antwort gegeben auch in bin mysql_install_db hat auch nix gebracht :(

Vieleicht kann mir ja jemand helfen!
Danke, Grüße Johannes

Ohje, was machst du denn da?! :eek:

Was genau willst du erreichen? Dass die MySQL-Datenbankdateien in /drive/data/mysql/ gespeichert werden? Dann solltest du deine Änderungen wieder rückgängig machen:

[client]
socket = /var/run/mysqld/mysqld.sock

[mysqld]
socket = /var/run/mysqld/mysqld.sock
Stattdessen musst du folgenden Parameter konfigurieren:

[mysqld]
data-dir = /drive/data/mysql
Du solltest am besten die MySQL-Dokumentation lesen bevor du an diversen Optionen herumspielst.

Hallo,

genau, dass möchte ich und ich bin nach mehreren Texten im Netz gegangen, die das gleiche gemacht haben. Da in meiner my.cnf kein parameter data-dir stand, habe ich ihn eingefügt. Nun wird beim starten in der log datei unknown variable angezeigt!
Also kanns so wohl auch net gehen oder?

Würdest du bitte deine jetzige MySQL-Konfiguration nochmal posten und uns sagen, welche MySQL-Version du hast und den relevanten Teil aus dem Logfile posten?

Ändere:

[mysqld]
socket = /var/lib/mysql/mysql.sock
in:

[mysqld]
socket = /var/lib/mysql/mysqld.sock
Und korrigiere meinen Fehler:

[mysqld]
data-dir = /drive/data/mysql
in:

[mysqld]
datadir = /drive/data/mysql

(nur noch so als randinfo)

Ich gehe davon aus, dass die Datenbank noch leer ist. In dem Fall solltest du vielleicht die Dateien löschen und die Datenbank neu anlegen lassen.

06.06.05, 22:29
Welche meinst du? Alle im Ordner /drive/data/mysql und alle im /var/lib/mysql?

Und dann mit mysql_install_db oda?

Alle im Ordner /drive/data/mysql und alle im /var/lib/mysql?
Natürlich die Dateien in /drive/data/mysql/, weil das dein aktuelles Datenverzeichnis für MySQL ist.


Und dann mit mysql_install_db oda?
Ja.

Die ganzen Fragen würden sich erübrigen, wenn du ins MySQL-Handbuch gucken würdest.
