Using the mysql_upgrade Command
mysql_upgrade is a Unix command that checks all tables in all databases for incompatibilities with your current version of the MySQL Server.www.hivelocity.net
To use mysql_upgrade, you’ll first need to make sure that your server is up and running. Then, from within the terminal, enter the following command:
shell> mysql_upgrade
The way mysql_upgrade works, is by automatically executing the following commands:
mysqlcheck --check-upgrade --all-databases --auto-repair
mysql_fix_privilege_tables
Code:
[root@server custombuild]# mysql_upgrade
The mysql_upgrade client is now deprecated. The actions executed by the upgrade client are now done by the server.
To upgrade, please start the new MySQL binary with the older data directory. Repairing user tables is done automatically. Restart is not required after upgrade.
The upgrade process automatically starts on running a new MySQL binary with an older data directory. To avoid accidental upgrades, please use the --upgrade=NONE option with the MySQL binary. The option --upgrade=FORCE is also provided to run the server upgrade sequence on demand.
It may be possible that the server upgrade fails due to a number of reasons. In that case, the upgrade sequence will run again during the next MySQL server start. If the server upgrade fails repeatedly, the server can be started with the --upgrade=MINIMAL option to start the server without executing the upgrade sequence, thus allowing users to manually rectify the problem.
