MARIADB-UPGRADE(1) MariaDB Database System MARIADB-UPGRADE(1)
mariadb-upgrade - check tables for MariaDB upgrade (mysql_upgrade
is now a symlink to mariadb-upgrade)
mysql_upgrade [options]
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:
• 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.
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.
• --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.
