“MariaDB is a community-developed branch of

the MySQL database, the impetus being the community maintenance of
its free status under GPL, as opposed to any uncertainty of MySQL
license status under its current ownership by Oracle.

The intent also being to maintain high fidelity with MySQL,
ensuring a “drop-in” replacement capability with library binary
equivalency and exacting matching with MySQL APIs and commands. It
includes the XtraDB storage engine as a replacement for InnoDB.

Its lead developer is Monty Widenius, the founder of MySQL and
Monty Program AB.”

Being curious I decide to install mariadb on my Freebsd 8.1 stable . My first option for install is via ports but at time writing I don’t find the mariadb port

After search and dig google I came up with solution on how to install mariadb from source.

Here the steps :

Add user and group for mariadb

# pw groupadd mysql
# pw adduser mysql -g mysql -d /usr/local/mysql

Download and extract mariadb tarball

# wget -c
http://ftp-stud.hs-esslingen.de/pub/Mirrors/mariadb/mariadb-5.1.50/kvm-tarbake-jaunty-x86/mariadb-5.1.50.tar.gz
&

#tar xvzf mariadb-5.1.50.tar.gz

#cd mariadb-5.1.50

Configure, make and make install

# ./configure ?with-plugins=max-no-ndb

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
To do so, start the server, then issue the following commands:

/usr/local/bin/mysqladmin -u root password ‘new-password’
/usr/local/bin/mysqladmin -u root -h goten.rasyid.net password ‘new-password’

Alternatively you can run:
/usr/local/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the MySQL manual for more instructions.

# cd /usr/local

# chown -R mysql:mysql var

Start mariadb for first time

# /usr/local/bin/mysqld_safe &

Make mariadb service start at boot time

create new file called mariadb and put in /usr/local/etc/rc.d

# ee /usr/local/etc/rc.d/mariadb

Enter this :

#!/bin/sh

# PROVIDE: mariadb

. /etc/rc.subr

/usr/local/bin/mysqld_safe &
fi
}

run_rc_command “$1″

make the script executable

# chmod +x /usr/local/etc/rc.d/mariadb

Enable the service by adding it to rc.conf

# echo ‘mariadb_enable=”YES”‘ >> /etc/rc.conf

Try restart server to test the script and check it with ps command.
