Description:
error msg:
launchd[1] System: com.apple.SystemStarter: Standard out/error: Starting MySQL database
server

starting mysql on 10.5 is not possible.

How to repeat:
just install the osx10.4 package and try to start mysql server.

Thank you for the report.

But Mac OS X 10.5 is not released yet. We will return to the report after Mac OS X 10.5
will be released.

Has anyone come up with a workaround for this bug yet?  I see no activity on this bug or
on Bug #29301

Leopard is in customer's hands already if they ordered from Amazon or Apple's online
store.  Does anyone at MySQL have any insight into how to run MySQL on Leopard before I go
and try to tackle this?

Cheers

Re-opening this bug now that Leopard has been released. (Were we really too cheap to
spring the $500 for a developer to join the Apple developer program and get access to the
pre-release developer seeds?)

I just successfully started mysql up on 10.5.  The 5.0.45 installer works fine, I was able
to use the client and connect without any problems.  I did have issues with PHP on 10.5,
but this was reconciled by altering php.ini to go directly to /private/tmp/mysql.sock
instead of where it defaults to at /tmp/mysql.sock  Note, if you want the mysqli extension
to work, you'll need to specify the socket file just the same.

Pax.

Installation of 5.0.45 worked fine. Server, Startup, and Preference Pane all.

I could not start up the server using the Preference Pane, however. I had to run
"/Library/StartupItems/MySQLCOM/MySQLCOM start" manually. Then I could connect with the
CLI client without any problems.

Once started, I could not stop the server using the Preference Pane either. However,
stopping it from the CLI with "/Library/StartupItems/MySQLCOM/MySQLCOM stop" worked fine.

In short, I can get the server to start and stop. But the Preference Pane, it does
nothing.

I have/had the same problem.. 

Running a chmod -R 777 on the whole mysql folder helps though.. so the problems seems to
be with some permissions.. running this probably isn't recommended though for production
environments.. :)

but for me, who wanted to try out ruby on rails, it is not a very big issue..

As previously posted, preferences pane is broken with 10.5.
mysql starts okay using mysqld_safe& however. havn't tried stopping it yet...

mysql  Ver 14.12 Distrib 5.0.41, for apple-darwin8.6.0 (powerpc) using readline 5.0

I think it also has to do with the fact that the mysql user has an underscore in front of
the user name in Leopard (don't know why!) change the username in mysql.server and it will
start properly after a reboot with the correct username as used in the setup.

Preference pane still doesn't work

I think you need to make a slight adjustment to one file called 'mysql.server' in the
directory '/usr/local/mysql/support-files/'. On line 62 change:
user=mysql
into:
user=_mysql

oh,
prefernces pane doesn't work because:

/usr/local/mysql/bin/mysqld: Can't create/write to file
'/var/folders/w3/w37wtiElECCtRBWy7MqtpU+++TI/-Tmp-/ibOGkulV' (Errcode: 13)
071029 14:28:39  InnoDB: Error: unable to create temporary file; errno: 13

don't know if it's a good thing but the following fixes it:

cd /var
chmod -R a+w folders

preferences pane will then start and stop mysql server.

sorry, i was wrong. worked once but not after a restart, don't know why :(

5.0.45 works fine on 10.5, but the preferences pane doesn't work.

There is no need to change the username from mysql to _mysql in the mysql.server file
because both usernames are valid and both are actually the same user.

The previous comments about having to reconfigure PHP to point to the MySQL socket in
/tmp/mysql.sock are still valid.

Apologies for the double post.

Just wanted to correct an error in a previous post about the mysql.sock file. The
directory "/private/tmp/" and "/tmp/" are the same directory; "/tmp/" is a link to
"/private/tmp/".

Contrary to the previous post, the default default location that PHP looks for the
mysql.sock file is *not* "/tmp/mysql.sock", it's actually "/var/mysql/", which is
incorrect in OSX 10.5.

So when pointing your php.ini to the mysql.sock location, just use "/tmp/mysql.sock".

Leopard has been out for a month, and MySQL AB could care less that MySQL won't run on it.
 They have done nothing to fix this bug.  

There are several workarounds posted on the web, but not all of them work.   It is up to
users to fiddle with lots of different things and do their own troubleshooting.   This
leaves a really bad taste in my mouth for MySQL.

I fully agree there and hope that considering these facts many developers give sqlite3 and
PostgreSQL a serious thought instead of just mindlessly go with the MySQL flow.

The startup item and the preference pane are not yet supported on Mac OS X 10.5. The MySQL
server itself and the command line client included in the OS X 10.4 package will work on
OS X 10.5. Please refer to the MySQL manual section on installing MySQL on Mac OS X for
instructions for starting the MySQL server from the command line without using the startup
item:

http://dev.mysql.com/doc/refman/5.0/en/mac-os-x-installation.html

No other changes are necessary to start the server in this way on OS X 10.5, including any
changes to settings regarding the user name, or to permissions.

I probably should have posted my positive experience earlier, but I've been running
without the startup item and preference pane (as suggested by the previous comment) since
a few days after Leopard was released and it's been running very smoothly.

I have found that it's only the pref pane that doesn't work in Leopard. You can set the
server to auto start using the MySQL Administrator Tool.  

It's slightly annoying, but no show stopper.  

It would be nice to see a proper Leopard release of the tools though.

I have a workaround for the issue with the "Can’t create/write to file
‘/var/folders/2F/2FtguLeuG1ibx1X9tbDS0E+++TI/-Tmp-/ibYWBjEU’ (Errcode: 13)" error.

To work around this, create a directory in your MySQL root called "tmp" or something, make
sure the server has permissions to write to it. Then open up your my.cnf and put this in
it:

tmpdir=/usr/local/mysql/tmp

For a more tutorial-friendly description to how to do this, see my blog post:
http://www.bluestatic.org/blog/2007/12/04/mysql-in-leopard/

After some fits and starts, I now appear to have mysql and php functioning properly under
OS 10.5.1 (Mac "Leopard"). I had to complete both 

(a) the step mentioned 31 Oct 20:42 by Richard Valk, modding mysql-server [line 62] so
that _mysql is the user (note underscore, which 10.5 apparently sets the mysql user to)
and
(b) the step mentioned 8 Nov 3:36 by Donald Tyler, modding /private/etc/php.ini [line 720]
so that mysql.default_socket = [blank]  became mysql.default_socket =
/private/tmp/mysql.sock.

There probably are other ways around some of these issues. For example, I suspect that one
could edit the database of users rename _mysql to be mysql. Also, I guess one could put a
sym link in the place that PHP is looking for the mysql.sock. 

I hope the path I've taken is the most sensible. *Sigh*

I was able to get the preference pane to start and stop mysql 5.0.45 on Leopard 10.5.1 by
changing the ownership of the mysql data folder.  Here is the terminal command I used:

sudo chown -R user /usr/local/mysql/data

Be sure to replace 'user' in the command with your user name and then you should be able
to start and stop the server through the preference pane.

A fixed version of the MySQL prefpane has been uploaded to:

ftp://ftp.mysql.com/pub/mysql/download/gui-tools/MySQL.prefPane-leopardfix.zip

In addition, it will be shipped with the next releases of the MySQL server for OSX.

An additional note:

It seems inability to start the server in Leopard could be caused by 2 reasons, one was an
incompatibility
of the prefpane with Leopard, which has been resolved in the above mentioned binary.
The other is incorrect permissions of the MySQL data directory, as commented by someone
else in this bug. The fixed prefpane will try to detect that problem and show a warning,
but it's still up to the user
to properly address it (chown -R mysql:wheel /usr/local/mysql/data)

Documentation notes:
MySQL.prefPane request admin rights and forwards those internally to a binary called
mahelper (same as mysql-administrator uses) that executes as root and calls the
/usr/local/mysql/support-files/mysql.server script to start and stop the server.

MySQL.prefPane uses "/usr/local/mysql/bin/mysqladmin ping" for checking if the server is
up or not.

It alters the file /etc/hostconfig for enable / disable the automatic startup. It
debug-logs through syslog (LOG_DEBUG level).
At start, it checks that the owner of the datadir (tries to get it from /etc/my.cnf or
uses default '/usr/local/mysql/data') is mysql/_mysql, if not, it issues a warning.

The code for MySQL.prefPane is included in mysql-administrator (located in
mysql-administrator/source/mac/PreferencePane, and shares the
mysql-administrator/source/mac/mahelper files with mysql-administrator)

I have tested a non released mysql-enterprise-gpl-5.0.58-osx10.4-powerpc.dmg package which
both includes the working MySQL.prefPane and a working StartupItem.pkg. I will update this
bug when I know in which versions it will be released in.

Until then, the working MySQL.prefPane is here:
ftp://ftp.mysql.com/pub/mysql/download/gui-tools/MySQL.prefPane-leopardfix.zip

and to get the StartupItem to work (see bug#25008), copy the (if existent)
/usr/local/MySQLCOM directory to /Library/StartupItems/MySQLCOM

From bug#25008 (which is about MySQLStartupItem, and the new packages will also include
the updated MySQL.prefPane):

Will be corrected in MySQL 5.0.56 (Mac OS X dmg not released yet),
5.0.58, 4.1.24 and 5.1.24
