mysql_fix_privilege_tables - upgrade MySQL system tables
In MySQL 5.1.7, mysql_fix_privilege_tables was superseded by mysql_upgrade, which
should be used instead. See mysql_upgrade(1).
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
mysql_fix_privilege_tables is an older script that previously was used to upgrade 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
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
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
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
After running the script, stop the server and restart it.
