MYSQL_UPGRADE(1) MariaDB Database System MYSQL_UPGRADE(1)
NAME
mysql_upgrade - check tables for MariaDB upgrade
SYNOPSIS
mysql_upgrade [options]
DESCRIPTION
mysql_upgrade examines all tables in all databases for
incompatibilities with the current version of the MariaDB Server.
mysql_upgrade also upgrades the system tables so that you can take
advantage of new privileges or capabilities that might have been added.
mysql_upgrade should be executed each time you upgrade MariaDB.
If a table is found to have a possible incompatibility, mysql_upgrade
performs a table check. If any problems are found, a table repair is
attempted.
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.
To use mysql_upgrade, make sure that the server is running, and then
invoke it like this:
shell> mysql_upgrade [options]
After running mysql_upgrade, stop the server and restart it so that any
changes made to the system tables take effect.
mysql_upgrade executes the following commands to check and repair
tables and to upgrade the system tables:
mysqlcheck --all-databases --check-upgrade --auto-repair
mysql < fix_priv_tables
mysqlcheck --all-databases --check-upgrade --fix-db-names --fix-table-names
Notes about the preceding commands:
o 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.
o For details about what checks the --check-upgrade option entails,
see the description of the FOR UPGRADE option of the CHECK TABLE
statement.
o fix_priv_tables represents a script generated internally by
mysql_upgrade that contains SQL statements to upgrade the tables in
the mysql database.
All checked and repaired tables are marked with the current MariaDB
version number. This ensures that next time you run mysql_upgrade with
the same version of the server, it can tell whether there is any need
to check or repair the table again.
mysql_upgrade also saves the MariaDB version number in a file named
mysql_upgrade_info in the data directory. This is used to quickly check
whether all tables have been checked for this release so that
table-checking can be skipped. To ignore this file and perform the
check regardless, use the --force option.
For this reason, mysql_upgrade needs to be run as a user with write
access to the data directory.
If you install MariaDB from RPM packages on Linux, you must install the
server and client RPMs. mysql_upgrade is included in the server RPM
but requires the client RPM because the latter includes mysqlcheck.
mysql_upgrade supports the following options, which can be specified on
the command line or in the [mysql_upgrade] and [client] option file
groups. Other options are passed to mysqlcheck. For example, it might
be necessary to specify the --password[=password] option.
mysql_upgrade also supports the options for processing option files.
o --help, -?
Display a short help message and exit.
o --basedir=path
Old option accepted for backward compatibility but ignored.
o --character-sets-dir=path
Old option accepted for backward compatibility but ignored.
o --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.
o --datadir=path
Old option accepted for backward compatibility but ignored.
o --debug=path, -# path
For debug builds, output debug log.
o --debug-check
Print some debugging information when the program exits.
o --debug-info, -T
Print debugging information and memory and CPU usage statistics
when the program exits.
o --default-character-set=name
Old option accepted for backward compatibility but ignored.
o --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.
o --host
Connect to MariaDB on the given host.
o --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.
o --port=port_num, -P port_num
The TCP/IP port number to use for the connection.
o --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.
o --silent
Print less information.
o --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.
o --ssl
Enable SSL for connection (automatically enabled with other flags).
Disable with --skip-ssl.
o --ssl-ca=name
CA file in PEM format (check OpenSSL docs, implies --ssl).
o --ssl-capath=name
CA directory (check OpenSSL docs, implies --ssl).
o --ssl-cert=name
X509 cert in PEM format (check OpenSSL docs, implies --ssl).
o --ssl-cipher=name
SSL cipher to use (check OpenSSL docs, implies --ssl).
o --ssl-key=name
X509 key in PEM format (check OpenSSL docs, implies --ssl).
o --ssl-crl=name
Certificate revocation list (check OpenSSL docs, implies --ssl).
o --ssl-crlpath=name
Certificate revocation list path (check OpenSSL docs, implies
--ssl).
o --ssl-verify-server-cert
Verify server's "Common Name" in its cert against hostname used
when connecting. This option is disabled by default.
o --tmpdir=path, -t path
The path name of the directory to use for creating temporary files.
o --upgrade-system-tables, -s
Only upgrade the system tables in the mysql database. Tables in
other databases are not checked or touched.
o --user=user_name, -u user_name
The MariaDB user name to use when connecting to the server and not
using the current login.
o --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
mysqlcheck commands used.
o --version, -V
Output version information and exit.
o --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.
o --write-binlog
Cause binary logging to be enabled while mysql_upgrade runs.
