Passaggio 1:installa i pacchetti richiesti
Per prima cosa dobbiamo installare tutti i pacchetti richiesti per l'installazione di Ruby sul nostro sistema usando il seguente comando.
# yuminstall gcc-c++ patch readline readline-devel zlib zlib-devel # yuminstall libyaml-devel libffi-devel openssl-devel make # yuminstall bzip2 autoconf automake libtool bison iconv-devel
Fase 2:installa RVM (Ruby Version Manager)
Installa l'ultima versione stabile di RVM sul tuo sistema usando il seguente comando. Questo comando scaricherà automaticamente tutti i file richiesti e li installerà sul tuo sistema.
# curl -Lget.rvm.io | bash -sstable
Ora configura l'ambiente di sistema prima di installare Ruby. Utilizzare il comando seguente per configurare l'ambiente rvm.
# source/etc/profile.d/rvm.sh
Fase 3:installa Ruby
Dopo aver completato la configurazione dell'ambiente RVM, installiamo il linguaggio Ruby usando il seguente comando.
# rvm install2.0.0

Fase 4:imposta la versione Ruby predefinita
Usa il comando rvm per impostare la versione predefinita di ruby da utilizzare per le applicazioni.
#rvm use 2.0.0 --default Using /usr/local/rvm/gems/ruby-2.0.0-p451
Usando il comando seguente puoi verificare che sia utilizzata la versione corrente di Ruby.
# ruby --version ruby 2.0.0p451 (2014-02-24 revision 45167) [i686-linux]
