+++ This bug was initially created as a clone of Bug #250039 +++

I am running akonadi 1.6.2, kmail 4.7.3 and have a very similar issue as in Bug #250039: Creating an IMAP resource fails and KMail crashes/exits on startup.
I tried to clean up akonadi but it still has this 'Failed to request resource "akonadi_maildir_resource_0"' issue.
What can I do?

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h myhost password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!
