Note

On Windows Server 2008 and Windows Vista, you must run mysql_upgrade with administrator privileges. You can do this by running a Command Prompt as Administrator and running the command. Failure to do so may result in the upgrade failing to execute correctly.

Caution

You should always back up your current MariaDB installation before performing an upgrade.

shell> mysql_upgrade [options]

mysqlcheck --all-databases --check-upgrade --auto-repair
mysql < fix_priv_tables
mysqlcheck --all-databases --check-upgrade --fix-db-names --fix-table-names

•Because mysql_upgrade invokes mysqlcheck with the --all-databases option, it processes all tables in all databases, which might take a long time to complete. Each table is locked and therefore unavailable to other sessions while it is being processed. Check and repair operations can be time-consuming, particularly for large tables.

•For details about what checks the --check-upgrade option entails, see the description of the FOR UPGRADE option of the CHECK TABLE statement.

•fix_priv_tables represents a script generated internally by mysql_upgrade that contains SQL statements to upgrade the tables in the mysql database.

•--help, -?

Display a short help message and exit.

•--basedir=path

Old option accepted for backward compatibility but ignored.

•--character-sets-dir=path

Old option accepted for backward compatibility but ignored.

•--check-if-upgrade-is-needed

Exit with a status code indicating if an upgrade is needed. Returns 0 if upgrade needed or current version couldn't be determined, 1 when no action required.

•--datadir=path

Old option accepted for backward compatibility but ignored.

•--debug=path, -# path

For debug builds, output debug log.

•--debug-check

Print some debugging information when the program exits.

•--debug-info, -T

Print debugging information and memory and CPU usage statistics when the program exits.

•--default-character-set=name

Old option accepted for backward compatibility but ignored.

•--force

Ignore the mysql_upgrade_info file and force execution of mysqlcheck even if mysql_upgrade has already been executed for the current version of MariaDB.

•--host

Connect to MariaDB on the given host.

•--password[=password], -p[password]

The password to use when connecting to the server. If you use the short option form (-p), you cannot have a space between the option and the password. If you omit the password value following the --password or -p option on the command line, mysql_upgrade prompts for one.

Specifying a password on the command line should be considered insecure. You can use an option file to avoid giving the password on the command line.

•--port=port_num, -P port_num

The TCP/IP port number to use for the connection.

•--protocol={TCP|SOCKET|PIPE|MEMORY}

The connection protocol to use for connecting to the server. It is useful when the other connection parameters normally would cause a protocol to be used other than the one you want.

•--silent

Print less information.

•--socket=path, -S path

For connections to localhost, the Unix socket file to use, or, on Windows, the name of the named pipe to use.

•--ssl

Enable SSL for connection (automatically enabled with other flags). Disable with --skip-ssl.

•--ssl-ca=name

CA file in PEM format (check OpenSSL docs, implies --ssl).

•--ssl-capath=name

CA directory (check OpenSSL docs, implies --ssl).

•--ssl-cert=name

X509 cert in PEM format (check OpenSSL docs, implies --ssl).

•--ssl-cipher=name

SSL cipher to use (check OpenSSL docs, implies --ssl).

•--ssl-key=name

X509 key in PEM format (check OpenSSL docs, implies --ssl).

•--ssl-crl=name

Certificate revocation list (check OpenSSL docs, implies --ssl).

•--ssl-crlpath=name

Certificate revocation list path (check OpenSSL docs, implies --ssl).

•--ssl-verify-server-cert

Verify server's "Common Name" in its cert against hostname used when connecting. This option is disabled by default.

•--tmpdir=path, -t path

The path name of the directory to use for creating temporary files.

•--upgrade-system-tables, -s

Only upgrade the system tables in the mysql database. Tables in other databases are not checked or touched.

•--user=user_name, -u user_name

The MariaDB user name to use when connecting to the server and not using the current login.

•--verbose

Display more output about the process. Using it twice will print connection arguments; using it 3 times will print out all CHECK, RENAME and ALTER TABLE commands used during the check phase; using it 4 times (added in MariaDB 10.0.14) will also write out all mariadb-check commands used; using it 5 times will print all the mariadb commands used and their results while running mysql_fix_privilege_tables script.

•--version, -V

Output version information and exit.

•--version-check, -k

Run this program only if its 'server version' matches the version of the server to which it's connecting. Note: the 'server version' of the program is the version of the MariaDB server with which it was built/distributed. Defaults to on; use --skip-version-check to disable.

•--write-binlog

Cause binary logging to be enabled while mysql_upgrade runs.
