Installing MySQL on Snow Leopard using MacPorts

Question

I am trying to install MySQL5 on Snow Leopard, but I am having some trouble. Here is my terminal log:

users-MacBook-Pro:~ sam$ sudo port install mysql5Password:

The MySQL client has been installed.
If you also want a MySQL server, install the mysql5-server port.

Installing MySQL system tables...
ERROR: 1004  Can't create file '/var/tmp/#sqlf2ef_1_0.frm' (errno: 9)
110125 20:22:45 [ERROR] Aborting

Installation of system tables failed!  Examine the logs in
/opt/local/var/db/mysql5 for more information.

You can try to start the mysqld daemon with:

    shell> /opt/local/libexec/mysqld --skip-grant &

and use the command line tool /opt/local/lib/mysql5/bin/mysql
to connect to the mysql database and look at the grant tables:

    shell> /opt/local/lib/mysql5/bin/mysql -u root mysql
    mysql> show tables

Try 'mysqld --help' if you have problems with paths.  Using --log
gives you a log in /opt/local/var/db/mysql5 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 /opt/local/lib/mysql5/bin/mysqlbug script!

I have tried repairing the my disks permissions but nothing seems to work :( Would appreciate any advice on how to get MySQL up and running!

Answer 1

Try this:

sudo chown -R mysql:mysql /opt/local/var/db/mysql5
sudo chmod u+rwx,go= /opt/local/var/db/mysql5
sudo /opt/local/lib/mysql5/bin/mysql_install_db --user=mysql

If you're having problem setting the root password, reset it using the instructions found here: http://dev.mysql.com/doc/refman/5.0/en/resetting-permissions.html#resetting-permissions-unix

For starting and stopping the mysql daemon I use the following aliases:

alias mysql_start='sudo /opt/local/etc/LaunchDaemons/org.macports.mysql5/mysql5.wrapper start';
alias mysql_stop='sudo /opt/local/etc/LaunchDaemons/org.macports.mysql5/mysql5.wrapper stop';
alias mysql_restart='sudo /opt/local/etc/LaunchDaemons/org.macports.mysql5/mysql5.wrapper restart';

Best of luck!

Answer 2

I had a similar issue, Reimund's answer here didn't solve it. However, first running as root:

sudo mysql_install_db --user=root

then setting the permissions as they should be:

sudo chown -R mysql:admin /opt/local/var/db/mysql5
sudo chmod u+rwx,go= /opt/local/var/db/mysql5

did the trick.
