The table is probably corrupted
So, in order to solve the problem above, the solution is simple. Just execute the following command :
mysql_upgrade -uroot -p
The following is the output of the command :
root@hostname:~# mysql_upgrade -uroot -p ... mysql.columns_priv OK mysql.db OK mysql.event OK mysql.func OK mysql.general_log Error : You can't use locks with log tables. status : OK mysql.help_category OK mysql.help_keyword OK mysql.help_relation OK mysql.help_topic OK mysql.host OK mysql.ndb_binlog_index OK mysql.plugin OK mysql.proc OK mysql.procs_priv OK mysql.servers OK mysql.slow_log Error : You can't use locks with log tables. status : OK mysql.tables_priv OK mysql.time_zone OK mysql.time_zone_leap_second OK mysql.time_zone_name OK mysql.time_zone_transition OK mysql.time_zone_transition_type OK mysql.user OK Running 'mysql_fix_privilege_tables'... OK ... Upgrade process completed successfully. Checking if update is needed. root@hostname:~#
This is the output after updating MySQL Database but in order to check whether the update process has been successfully carried out, re-execute the command :
root@hostname:~# mysql_upgrade -uroot -p Enter password: Checking if update is needed. This installation of MySQL is already upgraded to 5.7.20, use --force if you still need to run mysql_upgrade root@hostname:~#
After finishing the upgrade process through the execution of the above command, just add a new user based on the above query command executed before as shown below :
mysql> add user 'myuser'@'%' identified by 'mypassword'; Query OK, 0 rows affected (0,02 sec)
