Upgrading mysql on OS X 10.3 Server

With the latest discovery of some remote vulnerabilities in mysql and PHP, I had to upgrade my production server.
And to be clear, I don’t like updates.
Esp. not on mission critical apps. Updates tend to break things, you see:)

But running php 4.3.6 and mysql 4.0.20 was getting…unwise.

Upgrading PHP is easy, with the (imho) great installer of entropy.ch.

installer -verboseR -pkg ~/php-4.3.10.pkg -target /

Don’t forget afterwards to restore your httpd.conf and to edit /usr/local/php/httpd.conf.php to add:

AddType application/x-httpd-php .php
AddType application/x-httpd-php .html
AddType application/x-httpd-php-source .phps


MySQL is somewhat more tricky.
The version supplied by Apple is well…historic.
I like to compile MySQL from source (esp. because that takes 8,5 minute on my Xserve :) and install it to /usr/local/mysql-(version).
After that I create a symlink from /usr/local/mysql-(version) to /usr/local/mysql.
Take some care replacing the apple supplied mysql-binaries with symlinks to the up2date /usr/local/mysql/bin/ counterparts.
After this, upgrading mysql from source is painless.

The most recent upgrade:

# cd /usr/local/src
# gnutar -xzvf mysql-4.1.10a.tar.gz
# cd mysql-4.1.10a
# ./configure --with-openssl \
--prefix=/usr/local/mysql-4.1.10_a \
--localstatedir=/usr/local/mysql-4.1.10_a/data\
--mandir=/usr/local/share/man/\
--with-mysqld-user=mysql
# make
# make install
# cd /usr/local/
# mysqladmin -u root -p shutdown
# cp -R mysql/data mysql-4.1.10_a/data
# chown -r mysql:wheel mysql-4.1.10_a/data
# ln -s /usr/local/mysql-4.1.10_a /usr/local/mysql
# mysqld_safe &


That’s all. If something goes wrong, just restore the symlink to the “old” mysql-(version) and you’re safe.
Be aware of the new password hashing mysql uses from 4.1.1 of. I used the –old-password switch untill I’ve upgraded all my clients.
