|While quite old, this content may still be useful while MySQL is still at version 5.|
Please discuss in this thread on Ubuntu forums. 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.
- 1 Prerequisites
- 2 Compilation optimisation
- 3 Configuration
- 4 Testing
- 5 Starting Mysql at boot time
- 6 MySQL Tools
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
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
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.
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
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
sudo chown -R root /usr/local/mysql sudo chown -R mysql /usr/local/mysql/var sudo chgrp -R mysql /usr/local/mysql
Start the server
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!
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.
