When i run
mysql_upgrade (as it says in error details) it gives me
Installing MySQL system tables... Installation of system tables failed! Examine the logs in /var/lib/mysql for more information. You can try to start the mysqld daemon with: shell> /usr/sbin/mysqld --skip-grant & and use the command line tool /usr/bin/mysql to connect to the mysql database and look at the grant tables: shell> /usr/bin/mysql -u root mysql mysql> show tables Try 'mysqld --help' if you have problems with paths. Using --log gives you a log in /var/lib/mysql that may be helpful. Please consult the MySQL manual section 'Problems running mysql_install_db', and the manual section that describes problems on your OS. Another information source are the MySQL email archives available at http://lists.mysql.com/. Please check all of the above before mailing us! And remember, if you do mail us, you MUST use the /usr/scripts/mysqlbug script!
