Tested in Breezy. Mysql5.0 is already in Dapper. It is in main. It is installed when you install the default LAMP stack in Dapper.

Prerequisites

You must download MYSQL5 (of course ;)

wget http://dev.mysql.com/get/Downloads/MySQL-5.0/mysql-5.0.16.tar.gz/from/http://mysql.localhost.net.ar/
tar xzvf mysql-5.0.16.tar.gz
cd mysql-5.0.16/

You must install packages :

sudo apt-get install build-essential

You need development libraries

... but I'm not sure about which ones.

sudo apt-get install libncurses5 libncurses5-dev

...or you won't be able to compile on a server install

You need to create the user and group

sudo groupadd mysql
sudo useradd -g mysql mysql

Compilation optimisation

You can speed up Mysql with processor optimisation

If you have a different processor, change the CHOST, CFLAGS, CXXFLAGS.

If you don't know what it is, Take the Generic one!

The configuration for specific processors were not tested. If it compiles you're fine. If it doesn't try the generic one. Use only one of the following three

• Athlon-tbird XP (AMD)

export CHOST="i686-pc-linux-gnu"
export CFLAGS="-march=athlon-xp -O3 -pipe -fomit-frame-pointer -msse -mmmx  -mfpmath=sse"
export CXXFLAGS="-march=athlon-xp -O3 -pipe -fomit-frame-pointer -msse -mmmx  -mfpmath=sse -felide-constructors -fno-exceptions -fno-rtti"
export CXX=gcc 

• Pentium 4 (Intel)

export CHOST="i686-pc-linux-gnu"
export CFLAGS="-march=pentium4 -mcpu=pentium4 -O3 -pipe -fomit-frame-pointer -msse -mmmx  -mfpmath=sse"
export CXXFLAGS="-march=pentium4 -mcpu=pentium4 -O3 -pipe -fomit-frame-pointer -msse -mmmx  -mfpmath=sse -felide-constructors -fno-exceptions -fno-rtti"
export CXX=gcc 

• Generic

export CHOST="i686-pc-linux-gnu"
export CFLAGS="-mcpu=i686 -march=i686 -O3 -pipe -fomit-frame-pointer"
export CXX=gcc 

-fomit-frame-pointer should be omitted if you intend to debug. Otherwise leave it as it make mysql faster.

Configuration

This is a full configuration.

Do it in the MYSQL5 folder.

You can add/delete some of the options if you don't need it. This is intended to be a default mysql5 installation, again I'm not sure about this.

./configure \
--prefix=/usr/local/mysql \
--with-mysqld-user=mysql \
--without-debug \
--with-client-ldflags=-all-static \
--with-mysqld-ldflags=-all-static \
--disable-shared \
--localstatedir=/usr/local/mysql/data \
--with-extra-charsets=none \
--enable-assembler \
--with-unix-socket-path=/tmp/mysql.socket

make
sudo make install

This will install mysql in /usr/local/mysql and data in /usr/local/mysql/data.

my.conf

Now create the conf based in any of the pre-build confs. For small servers I recommend my-medium.cnf

sudo cp support-files/my-medium.cnf /etc/my.cnf

You should edit this file for your needs.

Create GRANT tables

You must create the GRANT tables, and there is a very easy way to do so.

sudo /usr/local/mysql/bin/mysql_install_db --user=mysql

(In later versions this script has been moved out of bin to /usr/local/mysql/scripts)

Changing Owners

sudo chown -R root  /usr/local/mysql
sudo chown -R mysql /usr/local/mysql/var
sudo chgrp -R mysql /usr/local/mysql

Testing

Start the server

/usr/local/mysql/bin/mysqld_safe -user=mysql&

Set a root password for MySQL (does not affect system root's password)

/usr/local/mysql/bin/mysqladmin -u root password new_password

Try to log in!

/usr/local/mysql/bin/mysql

You should add /usr/local/mysql/bin to your path so you can always use mysql, mysqldump, mysqladmin and some others right from the shell.

Starting Mysql at boot time

sudo cp support-files/mysql.server /etc/init.d/mysql
sudo chmod +x /etc/init.d/mysql
sudo update-rc.d mysql defaults

When you restart mysql should be up if everything went ok.
