In MySQL 5.1.7, mysql_fix_privilege_tables was superseded by mysql_upgrade, which should be used instead. See Section 4.4.8, “mysql_upgrade — Check Tables for MySQL Upgrade”.
Some releases of MySQL introduce changes to the structure of the
system tables in the mysql
database to add
new privileges or support new features. When you update to a new
version of MySQL, you should update your system tables as well
to make sure that their structure is up to date. Otherwise,
there might be capabilities that you cannot take advantage of.
mysql_fix_privilege_tables is an older script
that previously was used to uprade the system tables in the
mysql
database after a MySQL upgrade.
Before running mysql_fix_privilege_tables,
make a backup of your mysql
database.
On Unix or Unix-like systems, update the system tables by running the mysql_fix_privilege_tables script:
shell> mysql_fix_privilege_tables
You must run this script while the server is running. It
attempts to connect to the server running on the local host as
root
. If your root
account
requires a password, indicate the password on the command line
like this:
shell> mysql_fix_privilege_tables --password=root_password
The mysql_fix_privilege_tables script
performs any actions necessary to convert your system tables to
the current format. You might see some Duplicate column
name
warnings as it runs; you can ignore them.
After running the script, stop the server and restart it so that any changes made to the system tables take effect.
On Windows systems, MySQL distributions include a
mysql_fix_privilege_tables.sql
SQL script
that you can run using the mysql client. For
example, if your MySQL installation is located at
C:\Program Files\MySQL\MySQL Server
5.1
, the commands look like this:
C:\>cd "C:\Program Files\MySQL\MySQL Server 5.1"
C:\>bin\mysql -u root -p mysql
mysql>SOURCE share/mysql_fix_privilege_tables.sql
Prior to version 5.1.17, the
mysql_fix_privilege_tables.sql
script is
found in the scripts
directory.
The mysql command will prompt you for the
root
password; enter it when prompted.
If your installation is located in some other directory, adjust the path names appropriately.
As with the Unix procedure, you might see some
Duplicate column name
warnings as
mysql processes the statements in the
mysql_fix_privilege_tables.sql
script; you
can ignore them.
After running the script, stop the server and restart it.
