MariaDB è disponibile attraverso il gestore di pacchetti [[http://mxcl.github.com/homebrew/|Homebrew]], che è stato descritto come package manager che manca a Mac OS X. Una volta installato Homebrew (eseguendo da riga di comando <<code>>brew<</code>>), tutto ciò che occorre fare è questo:

<<code>>
brew update
<</code>>

== Compilare MariaDB
A questo punto è possibile eseguire ricerche (<<code>>brew search mariadb<</code>>) e, se si desiderano maggiori informazioni, si può eseguire: <<code>>brew info mariadb<</code>>. Quando si è pronti a installare MariaDB, si esegua semplicemente:

<<code>>
brew install mariadb
<</code>>

Con MariaDB 5.2.6, produce un output su riga di comando simile al seguente:
<<code>>

lovegood:~ byte$ brew install mariadb
Warning: It appears you have Macports or Fink installed
Software installed with other package managers causes known problems for
Homebrew. If formula fail to build uninstall Macports/Fink and reinstall any
affected formula.

==> make install
==> Caveats
This formula is keg-only, so it was not symlinked into /usr/local.

OS X provides the BSD libedit library, which shadows libreadline.
In order to prevent conflicts when programs look for libreadline we are
defaulting this GNU Readline installation to keg-only.

Generally there are no consequences of this for you.
If you build your own software and it requires this formula, you'll need
to add its lib & include paths to your build variables:

LDFLAGS: -L/usr/local/Cellar/readline/6.2.1/lib
  CPPFLAGS: -I/usr/local/Cellar/readline/6.2.1/include
==> Summary

==> Caveats
Set up databases with:
    unset TMPDIR
    mysql_install_db

If this is your first install, automatically load on login with:
    cp /usr/local/Cellar/mariadb/5.2.6/com.mysql.mysqld.plist ~/Library/LaunchAgents
    launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist

If this is an upgrade and you already have the com.mysql.mysqld.plist loaded:
    launchctl unload -w ~/Library/LaunchAgents/com.mysql.mysqld.plist
    cp /usr/local/Cellar/mariadb/5.2.6/com.mysql.mysqld.plist ~/Library/LaunchAgents
    launchctl load -w ~/Library/LaunchAgents/com.mysql.mysqld.plist

Note on upgrading:
    We overwrite any existing com.mysql.mysqld.plist in ~/Library/LaunchAgents
    if we are upgrading because previous versions of this brew created the
    plist with a version specific program argument.

Or start manually with:
    mysql.server start
Warning: m4 macros were installed to "share/aclocal".
Homebrew does not append "/usr/local/share/aclocal"
to "/usr/share/aclocal/dirlist". If an autoconf script you use
requires these m4 macros, you'll need to add this path manually.
==> Summary
/usr/local/Cellar/mariadb/5.2.6: 231 files, 44M, built in 10.9 minutes

<</code>>

== Installare MariaDB
Completato questo passaggio, occorre eseguire:
<<code>>
unset TMPDIR
mysql_install_db
<</code>>

Quando si avvia <<code>>mysql_install_db<</code>>,si riceve l'output seguente:
<<code>>

lovegood:~ byte$ mysql_install_db 
Installing MariaDB/MySQL system tables in '/usr/local/var/mysql' ...
OK
Filling help tables...
OK

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/Cellar/mariadb/5.2.6/bin/mysqladmin -u root password 'new-password'
/usr/local/Cellar/mariadb/5.2.6/bin/mysqladmin -u root -h lovegood.local password 'new-password'

Alternatively you can run:
/usr/local/Cellar/mariadb/5.2.6/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 MariaDB knowledge or the MySQL manual for more instructions.

You can start the MariaDB daemon with:
cd /usr/local/Cellar/mariadb/5.2.6 ; /usr/local/Cellar/mariadb/5.2.6/bin/mysqld_safe --datadir=/usr/local/var/mysql

You can test the MariaDB daemon with mysql-test-run.pl
cd /usr/local/Cellar/mariadb/5.2.6/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/local/Cellar/mariadb/5.2.6/bin/mysqlbug script!

== Avviare MariaDB
Completato questo passaggio, se si è in un ambiente di produzione, si ricordi di avviare <<code>>mysql_secure_installation<</code>>.Se si sta eseguendo un test, si seguano queste istruzioni:

<<code>>
lovegood:~ byte$ cd /usr/local/Cellar/mariadb/5.2.6 ; /usr/local/Cellar/mariadb/5.2.6/bin/mysqld_safe --datadir=/usr/local/var/mysql
110614 20:27:38 mysqld_safe Logging to '/usr/local/var/mysql/lovegood.local.err'.
chown: /usr/local/var/mysql/lovegood.local.err: Operation not permitted
110614 20:27:38 mysqld_safe Starting mysqld daemon with databases from /usr/local/var/mysql
<</code>>

Ecco fatto! E' ora possibile eseguire <<code>>mysql -uroot<</code>> ed effettuare il login.

== Usare MariaDB
<<code>>

== Aggiornare MariaDB

Prima occorre aggiornare la propria installazione di brew. Si può farlo con il comando <<code>>brew update<</code>>.Poi si esegua semplicemente:

<<code>>
brew upgrade mariadb
<</code>>

E' possibile che appaiano alcuni messaggi di errore su OS X 10.7:
<<code>>
Warning: Your Xcode (4.3.3) is outdated
Please install Xcode 4.5.2.
<</code>>

E' possibile ignorare questi errori in modo sicuro e aggiornare a 5.5.28 senza problemi.

== Problemi noti
Attualmente (serie 5.3), nella compilazione di default mancano alcuni Storage Engine. Si può verificarlo così:
<<code>>

== Perché non ci sono binari per Mac nella pagina dei download

MariaDB è un progetto open source e per poter fornire i binari per una specifica piattaforma ha bisogno di qualcuno che:
* Fornisca un [[about-buildbot|buildbot slave]] con Mac OSX dove poter creare le build.
* Aiuti a creare i pacchetti appropriati per Mac OSX.
* [[donations|Ci sponsorizzi]] con una macchina Mac OSX per le build.
