Compilare MariaDB su Mac OS X usando Homebrew
Contents
MariaDB è disponibile attraverso il gestore di pacchetti Homebrew, che è stato descritto come package manager che manca a Mac OS X. Una volta installato Homebrew (eseguendo da riga di comando brew
), tutto ciò che occorre fare è questo:
brew update
Compilare MariaDB
A questo punto è possibile eseguire ricerche (brew search mariadb
) e, se si desiderano maggiori informazioni, si può eseguire: brew info mariadb
. Quando si è pronti a installare MariaDB, si esegua semplicemente:
brew install mariadb
Con MariaDB 5.2.6, produce un output su riga di comando simile al seguente:
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. Also installing dependencies: readline ==> Downloading ftp://ftp.cwru.edu/pub/bash/readline-6.2.tar.gz ######################################################################## 100.0% ==> Downloading patches ######################################################################## 100.0% ==> Patching patching file vi_mode.c patching file callback.c ==> ./configure --prefix=/usr/local/Cellar/readline/6.2.1 --mandir=/usr/local/Ce ==> 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 /usr/local/Cellar/readline/6.2.1: 32 files, 2.1M, built in 31 seconds ==> Downloading http://ftp.osuosl.org/pub/mariadb/mariadb-5.2.6/kvm-tarbake-jaun ######################################################################## 100.0% ==> ./configure --without-docs --without-debug --disable-dependency-tracking --p ==> make install ==> 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 lovegood:~ byte$
Installare MariaDB
Completato questo passaggio, occorre eseguire:
unset TMPDIR mysql_install_db
Quando si avvia mysql_install_db
,si riceve l'output seguente:
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!

Alternatively consider joining our community based development effort: http://askmonty.org/wiki/index.php/MariaDB#How_can_I_participate_in_the_development_of_MariaDB lovegood:~ byte$
Avviare MariaDB
Completato questo passaggio, se si è in un ambiente di produzione, si ricordi di avviare mysql_secure_installation
.Se si sta eseguendo un test, si seguano queste istruzioni:
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
Ecco fatto! E' ora possibile eseguire mysql -uroot
ed effettuare il login.
Usare MariaDB

Aggiornare MariaDB
Prima occorre aggiornare la propria installazione di brew. Si può farlo con il comando brew update
.Poi si esegua semplicemente:
brew upgrade mariadb
E' possibile che appaiano alcuni messaggi di errore su OS X 10.7:
Warning: Your Xcode (4.3.3) is outdated Please install Xcode 4.5.2.
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:

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 buildbot slave con Mac OSX dove poter creare le build.
- Aiuti a creare i pacchetti appropriati per Mac OSX.
- Ci sponsorizzi con una macchina Mac OSX per le build.
