Hi, provedl jsem instalaci MYSQL Server na linuxovou distribuci Ubuntu Server 9.04. Po instalaci vše bylo OK. V adresáři /etc/mysql/my.cnf jsem změnil DATADIR s původní (/var/lib/mysql) hodnoty na /zmysql. Pod root jsem překopíroval vytvořenou DB do složky /zmysql.

Postup.:
mkdir /zmysql
chown mysql:mysql /zmysql
chmod 777 /zmysql
Překopíroval jsem data s adresáře /var/lib/mysql do adreáře /zmysql

Installation of system tables failed!

Examine the logs in /zmysql for more information.
You can try to start the mysqld daemon with:
/usr/sbin/mysqld --skip-grant &
and use the command line tool
/usr/bin/mysql to connect to the mysql
database and look at the grant tables:

shell> /usr/bin/mysql -u root mysql
mysql> show tables

Try 'mysqld --help' if you have problems with paths. Using --log
gives you a log in /zmysql that may be helpful.

Please consult the MySQL manual section: 'Problems running mysql_install_db',
and the manual section that describes problems on your OS.

# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.

# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
