Not able to reset mysql root password
Hi,
My root password for mysql has some problem as it dosent allow me to login....
all commands to reset it failed. so I removed mysql
yum remove mysql
and installed it by
yum install mysql mysql-devel mysql-server
and it installed fine
I gave chkconfig --levels 235 mysqld on
started my mysql server and when I give
mysqladmin -u root password new_password
it throws error
mysqladmin:
You cannot use 'password' command as mysqld runs
with grant tables disabled (was started with --skip-grant-tables).
Use: "mysqladmin flush-privileges password '*'" instead
I had given a safe mode skip grant command which just hung...could that be a problem....Please let me know what needs to be done.
Regards,
vijaya.

mysql_install_db
MYSQL_INSTALL_DB() MYSQL_INSTALL_DB()
NAME
mysql_install_db - initialize MySQL data directory
SYNOPSIS
mysql_install_db [options]
DESCRIPTION
mysql_install_db initializes the MySQL data directory and creates the system tables that it contains, if they do not exist.
To invoke mysql_install_db, use the following syntax:
shell> mysql_install_db [options]
Because the MySQL server, mysqld, needs to access the data directory when it runs later, you should either run mysql_install_db from the
same account that will be used for running mysqld or run it as root and use the --user option to indicate the user name that mysqld will
run as. It might be necessary to specify other options such as --basedir or --datadir if mysql_install_db does not use the correct
locations for the installation directory or data directory. For example:
shell> bin/mysql_install_db --user=mysql
--basedir=/opt/mysql/mysql
--datadir=/opt/mysql/mysql/data
mysql_install_db needs to invoke mysqld with the --bootstrap and --skip-grant-tables options (see Section 2.3.2, "Typical configure
Options"). If MySQL was configured with the --disable-grant-options option, --bootstrap and --skip-grant-tables will be disabled. To handle
this, set the MYSQLD_BOOTSTRAP environment variable to the full path name of a server that has all options enabled. mysql_install_db will
use that server.
mysql_install_db supports the following options, which can be specified on the command line or in the [mysql_install_db] and (if they are
common to mysqld) [mysqld] option file groups.
o --basedir=path
The path to the MySQL installation directory.
o --force
Cause mysql_install_db to run even if DNS does not work. In that case, grant table entries that normally use host names will use IP
addresses.
o --datadir=path, --ldata=path
The path to the MySQL data directory.
o --rpm
For internal use. This option is used by RPM files during the MySQL installation process.
o --skip-name-resolve
Use IP addresses rather than host names when creating grant table entries. This option can be useful if your DNS does not work.
o --srcdir=path
For internal use. The directory under which mysql_install_db looks for support files such as the error message file and the file for
populating the help tables. This option was added in MySQL 5.1.14.
o --user=user_name
The login user name to use for running mysqld. Files and directories created by mysqld will be owned by this user. You must be root to
use this option. By default, mysqld runs using your current login name and files and directories that it creates will be owned by you.
o --verbose
Verbose mode. Print more information about what the program does.
o --windows
For internal use. This option is used for creating Windows distributions.
