NAME
6       mysql_upgrade - check tables for MySQL upgrade
7

SYNOPSIS
9       mysql_upgrade [options]
10

DESCRIPTION
12       mysql_upgrade should be executed each time you upgrade MySQL. It checks
13       all tables in all databases for incompatibilities with the current
14       version of MySQL Server. If a table is found to have a possible
15       incompatibility, it is checked. If any problems are found, the table is
16       repaired.  mysql_upgrade also upgrades the system tables so that you
17       can take advantage of new privileges or capabilities that might have
18       been added.
19
20       All checked and repaired tables are marked with the current MySQL
21       version number. This ensures that next time you run mysql_upgrade with
22       the same version of the server, it can tell whether there is any need
23       to check or repair the table again.
24
25       mysql_upgrade also saves the MySQL version number in a file named
26       mysql_upgrade.info in the data directory. This is used to quickly check
27       if all tables have been checked for this release so that table-checking
28       can be skipped. To ignore this file, use the --force option.
29
30       To check and repair tables and to upgrade the system tables,
31       mysql_upgrade executes the following commands:
32
33          mysqlcheck --check-upgrade --all-databases --auto-repair
34          mysql_fix_privilege_tables
35
36       mysql_upgrade supersedes the older mysql_fix_privilege_tables script.
37       In MySQL 5.0.19, mysql_upgrade was added as a shell script and worked
38       only for Unix systems. As of MySQL 5.0.25, mysql_upgrade is an
39       executable binary and is available on all systems. On systems older
40       than those supporting mysql_upgrade, you can execute the mysqlcheck
41       command manually, and then upgrade your system tables as described in
42       mysql_fix_privilege_tables(1).
43
44       For details about what is checked, see the description of the FOR
45       UPGRADE option of the CHECK TABLE statement (see Section 5.2.3, “CHECK
46       TABLE Syntax”).
47
48       To use mysql_upgrade, make sure that the server is running, and then
49       invoke it like this:
50
51          shell> mysql_upgrade [options]
52
53       mysql_upgrade reads options from the command line and from the
54       [mysql_upgrade] group in option files. It supports the following
55       options:
56
57       ·  --help
58
59          Display a short help message and exit.
60
61       ·  --basedir=path
62
63          The path to the MySQL installation directory.
64
65       ·  --datadir=path
66
67          The path to the data directory.
68
69       ·  --force
70
71          Force execution of mysqlcheck even if mysql_upgrade has already been
72          executed for the current version of MySQL. (In other words, this
73          option causes the mysql_upgrade.info file to be ignored.)
74
75       ·  --user=user_name, -u user_name
76
77          The MySQL username to use when connecting to the server. The default
78          username is root.
79
80       ·  --verbose
81
82          Verbose mode. Print more information about what the program does.
83
84
85       Other options are passed to mysqlcheck and to
86       mysql_fix_privilege_tables. For example, it might be necessary to
87       specify the --password[=password] option.
