If the table cannot be repaired, see Section\ \&2.11.3, \(lqRebuilding or Repairing Tables or Indexes\(rq for manual table repair strategies\&. .PP You should execute \fBmysql_upgrade\fR each time you upgrade MySQL\&. .PP As of MySQL 5\&.7\&.5, \fBmysql_upgrade\fR communicates directly with the MySQL server, sending it the SQL statements required to perform an upgrade\&. Before 5\&.7\&.5, \fBmysql_upgrade\fR invokes the \fBmysql\fR and \fBmysqlcheck\fR client programs to perform the required operations\&. For the older implementation, if you install MySQL from RPM packages on Linux, you must install the server and client RPMs\&. \fBmysql_upgrade\fR is included in the server RPM but requires the client RPM because the latter includes \fBmysqlcheck\fR\&. (See Section\ \&2.5.5, \(lqInstalling MySQL on Linux Using RPM Packages from Oracle\(rq\&.) .if n \{\ .sp .\} .RS 4 .it 1 an-trap .nr an-no-space-flag 1 .nr an-break-flag 1 .br .ps +1 \fBImportant\fR .ps -1 .br .PP As of MySQL 5\&.7\&.12, the default \fB\-\-early\-plugin\-load\fR value is empty\&. To load the keyring_file plugin, you must use an explicit \fB\-\-early\-plugin\-load\fR option with a nonempty value\&. .PP In MySQL 5\&.7\&.11, the default \fB\-\-early\-plugin\-load\fR value was the name of the keyring_file plugin library file, so that plugin was loaded by default\&. InnoDB tablespace encryption requires the keyring_file plugin to be loaded prior to InnoDB initialization, so this change of default value introduces an incompatibility for upgrades from 5\&.7\&.11 to 5\&.7\&.12 or higher\&. Administrators who have encrypted InnoDB tablespaces must take explicit action to ensure continued loading of the keyring_file plugin: Start the server with an \fB\-\-early\-plugin\-load\fR option that names the plugin library file\&. For additional information, see Section\ \&6.5.4, \(lqThe MySQL Keyring\(rq\&. .sp .5v .RE .if n \{\ .sp .\} .RS 4 .it 1 an-trap .nr an-no-space-flag 1 .nr an-break-flag 1 .br .ps +1 \fBImportant\fR .ps -1 .br .PP If you upgrade to MySQL 5\&.7\&.2 or later from a version older than 5\&.7\&.2, a change to the mysql\&.user table requires a special sequence of steps to perform an upgrade using \fBmysql_upgrade\fR\&. For details, see Section\ \&2.11.1.2, \(lqChanges Affecting Upgrades to MySQL 5.7\(rq\&. .sp .5v .RE .if n \{\ .sp .\} .RS 4 .it 1 an-trap .nr an-no-space-flag 1 .nr an-break-flag 1 .br .ps +1 \fBNote\fR .ps -1 .br .PP On Windows Server 2008, Vista, and newer, you must run \fBmysql_upgrade\fR 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\&. .sp .5v .RE .if n \{\ .sp .\} .RS 4 .it 1 an-trap .nr an-no-space-flag 1 .nr an-break-flag 1 .br .ps +1 \fBCaution\fR .ps -1 .br .PP You should always back up your current MySQL installation \fIbefore\fR performing an upgrade\&. See Section\ \&7.2, \(lqDatabase Backup Methods\(rq\&. .PP Some upgrade incompatibilities may require special handling before you upgrade your MySQL installation and run \fBmysql_upgrade\fR\&. See Section\ \&2.11.1, \(lqUpgrading MySQL\(rq, for instructions on determining whether any such incompatibilities apply to your installation and how to handle them\&. .sp .5v .RE .PP To use \fBmysql_upgrade\fR, make sure that the server is running\&. Then invoke it like this to check and repair tables and to upgrade the system tables: .sp .if n \{\ .RS 4 .\} .nf shell> \fBmysql_upgrade [\fR\fB\fIoptions\fR\fR\fB]\fR .fi .if n \{\ .RE .\} .PP After running \fBmysql_upgrade\fR, stop the server and restart it so that any changes made to the system tables take effect\&. .PP If you have multiple MySQL server instances running, invoke \fBmysql_upgrade\fR with connection parameters appropriate for connecting to the desired server\&. For example, with servers running on the local host on parts 3306 through 3308, upgrade each of them by connecting to the appropriate port: .sp .if n \{\ .RS 4 .\} .nf shell> \fBmysql_upgrade \-\-protocol=tcp \-P 3306 [\fR\fB\fIother_options\fR\fR\fB]\fR shell> \fBmysql_upgrade \-\-protocol=tcp \-P 3307 [\fR\fB\fIother_options\fR\fR\fB]\fR shell> \fBmysql_upgrade \-\-protocol=tcp \-P 3308 [\fR\fB\fIother_options\fR\fR\fB]\fR .fi .if n \{\ .RE .\} .PP For local host connections on Unix, the \fB\-\-protocol=tcp\fR option forces a connection using TCP/IP rather than the Unix socket file\&. .PP \fBmysql_upgrade\fR 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\&. .PP For details about what table\-checking operations entail, see the description of the FOR UPGRADE option of the CHECK TABLE statement (see Section\ \&13.7.2.2, \(lqCHECK TABLE Syntax\(rq)\&. .PP All checked and repaired tables are marked with the current MySQL version number\&. This ensures that next time you run \fBmysql_upgrade\fR with the same version of the server, it can tell whether there is any need to check or repair the table again\&. .PP \fBmysql_upgrade\fR also saves the MySQL 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 \fB\-\-force\fR option\&. .PP As of MySQL 5\&.7\&.2, \fBmysql_upgrade\fR checks user table rows and, for any row with an empty plugin column, sets that column to \*(Aqmysql_native_password\*(Aq or \*(Aqmysql_old_password\*(Aq depending on the hash format of the Password column value\&. As of MySQL 5\&.7\&.5, support for pre\-4\&.1 password hashing and mysql_old_password was removed, so \fBmysql_upgrade\fR sets empty plugin values to \*(Aqmysql_native_password\*(Aq if the credentials use a hash format compatible with that plugin\&. Rows with a pre\-4\&.1 password hash must be upgraded manually\&. For account upgrade instructions, see Section\ \&6.5.1.3, \(lqMigrating Away from Pre-4.1 Password Hashing and the mysql_old_password Plugin\(rq\&. .PP \fBmysql_upgrade\fR does not upgrade the contents of the help tables\&. For upgrade instructions, see Section\ \&5.1.13, \(lqServer-Side Help\(rq\&. .PP As of MySQL 5\&.7\&.7, unless invoked with the \fB\-\-skip\-sys\-schema\fR option, \fBmysql_upgrade\fR installs the sys schema if it is not installed, and upgrades it to the current version otherwise\&. \fBmysql_upgrade\fR returns an error if a sys schema exists but has no version view, on the assumption that its absence indicates a user\-created schema: .sp .if n \{\ .RS 4 .\} .nf Error occurred: A sys schema exists with no sys\&.version view\&. If you have a user created sys schema, this must be renamed for the upgrade to succeed\&. .fi .if n \{\ .RE .\} .PP To upgrade in this case, remove or rename the existing sys schema first\&. .PP In MySQL 5\&.7\&.9 and later, \fBmysql_upgrade\fR checks for partitioned InnoDB tables that were created using the generic partitioning handler and attempts to upgrade them to InnoDB native partitioning (used in MySQL 5\&.7\&.6 and later)\&. (Bug #76734, Bug #20727344) Also beginning with MySQL 5\&.7\&.9, you can upgrade such tables individually in the \fBmysql\fR client using the ALTER TABLE \&.\&.\&. UPGRADE PARTITIONING SQL statement\&. .PP By default, \fBmysql_upgrade\fR runs as the MySQL root user\&. If the root password is expired when you run \fBmysql_upgrade\fR, you will see a message that your password is expired and that \fBmysql_upgrade\fR failed as a result\&. To correct this, reset the root password to unexpire it and run \fBmysql_upgrade\fR again\&. First, connect to the server as root: .sp .if n \{\ .RS 4 .\} .nf shell> \fBmysql \-u root \-p\fR Enter password: \fB****\fR <\- enter root password here .fi .if n \{\ .RE .\} .PP Reset the password using the appropriate SQL statement\&. As of MySQL 5\&.7\&.6, use ALTER USER: .sp .if n \{\ .RS 4 .\} .nf mysql> \fBALTER USER USER() IDENTIFIED BY \*(Aq\fR\fB\fIroot\-password\fR\fR\fB\*(Aq;\fR .fi .if n \{\ .RE .\} .PP Before 5\&.7\&.6, use SET PASSWORD: .sp .if n \{\ .RS 4 .\} .nf mysql> \fBSET PASSWORD = PASSWORD(\*(Aqroot\-password\*(Aq);\fR .fi .if n \{\ .RE .\} .PP Then exit \fBmysql\fR and run \fBmysql_upgrade\fR again: .sp .if n \{\ .RS 4 .\} .nf shell> \fBmysql_upgrade [\fR\fB\fIoptions\fR\fR\fB]\fR .fi .if n \{\ .RE .\} .PP \fBmysql_upgrade\fR supports the following options, which can be specified on the command line or in the [mysql_upgrade] and [client] groups of an option file\&.
