Akonadi Server Self-Test Report
===============================

Test 1:  SUCCESS
--------

Database driver found.
Details: The QtSQL driver 'QMYSQL' is required by your current Akonadi server configuration and was found on your system.

File content of '/root/.config/akonadi/akonadiserverrc':
[%General]
Driver=QMYSQL
SizeThreshold=4096
ExternalPayload=false

Options="UNIX_SOCKET=/root/.local/share/akonadi/db_misc/mysql.socket"
ServerPath=/usr/sbin/mysqld
StartServer=true


Test 2:  SUCCESS
--------

MySQL server found.
Details: You currently have configured Akonadi to use the MySQL server '/usr/sbin/mysqld'.
Make sure you have the MySQL server installed, set the correct path and ensure you have the necessary read and execution rights on the server executable. The server executable is typically called 'mysqld', its locations varies depending on the distribution.

Test 3:  SUCCESS
--------

MySQL server is executable.
Details: MySQL server found: /usr/sbin/mysqld  Ver 5.0.67 for suse-linux-gnu on x86_64 (SUSE MySQL RPM)


Test 4:  SUCCESS
--------

No current MySQL error log found.
Details: The MySQL server did not report any errors during this startup into '/root/.local/share/akonadi/db_data/mysql.err'.

Test 5:  SUCCESS
--------

MySQL server default configuration found.
Details: The default configuration for the MySQL server was found and is readable at <a href='/usr/local/share/config/akonadi/mysql-global.conf'>/usr/local/share/config/akonadi/mysql-global.conf</a>.

Comment 1 Thorsten Staerk 2009-09-28 12:35:13 UTC 
When trying to manually start mysql:
/usr/sbin/mysqld --defaults-file=/root/.local/share/akonadi//mysql.conf --datadir=/root/.local/share/akonadi/db_data/ --socket=/root/.local/share/akonadi/db_misc/mysql.socket


I get:
090928 12:39:43 [ERROR] Fatal error: Please read "Security" section of the manual to find out how to run mysqld as root!

Comment 2 Volker Krause 2009-09-28 13:09:16 UTC 
Looks like a problem with running Akonadi (or rather MySQL) as root. Does it work with a normal user?
Comment 3 Thorsten Staerk 2010-01-15 10:52:37 UTC 
Workaround is to use a central mysql daemon: http://techbase.kde.org/Projects/PIM/Akonadi#Can_Akonadi_use_a_normal_MySQL_server_running_on_my_system.3F
Comment 4 Will Stephenson 2010-02-08 12:06:07 UTC 
I just had a user report this as well.  Mysql refuses to start with the out of the box config when kdepim apps are run as root.  It works fine as a regular user.  

If it's not worth fixing the config to allow running as root (although this case might be relevant on mobile devices where everything runs as root) then at least the framework should check for root and fail gracefully instead of letting mysql abort.
Comment 5 Will Stephenson 2010-03-24 10:59:08 UTC 
I've added a self-test to clearly warn the user why Akonadi+MySQL won't start as root.  
I can see that it should be possible to run as root if you really want to, which can be done with a local MySQL by adding "user=root" to mysql-local.conf, but this is so corner I think it's sufficient to warn the user that it's a bad idea.

svn rev 1106949 is the commit.
