Installazione Alfresco e DB MySql

salvatore_conta · ‎16 Feb 2012

Salve,
sono nuovo del forum e nuovo a questa applicazione.Avrei un quesito per chiunque ne sappia di più e voglia aiutarmi.
Sapreste dirmi e dettagliarmi il processo di installazione e come associare mysql su alfresco e come alfresco crea le tabelle necessarie?
Grazie

Devi creare un nuovo database ed un nuovo utente che accede a questo database su MySQL, ad esempio puoi utilizzare il seguente script SQL:


create database alfresco4 default character set utf8 collate utf8_bin;
grant all on alfresco4* to 'alfresco4'@'localhost' identified by 'alfresco4' with grant option;
grant all on alfresco4* to 'alfresco4'@'localhost.localdomain' identified by 'alfresco4' with grant option;
‍‍‍‍‍

Questo script crea un nuovo database alfresco4 con un nuovo utente alfresco4 che può effettuare tutte le operazioni di creazione e modifica degli schema (SDL).

Una volta eseguito lo script a questo punto basta configurare Alfresco all'interno del classloader condiviso dell'application server all'interno del file di configurazione che si chiama alfresco-global.properties. Quì trovi la configurazione MySQL da scommentare e da modificare per poter accedere al nuovo database, ad esempio la seguente:


#
# Sample custom content and index data location
#
dir.root=/Applications/alfresco/alfresco4/alf_data
#dir.keystore=${dir.root}/keystore

#
# Sample database connection properties
#
db.username=alfresco4
db.password=alfresco4

#
# MySQL connection
#
db.driver=org.gjt.mm.mysql.Driver
db.url=jdbc:mysql://localhost/alfresco4?useUnicode=yes&characterEncoding=UTF-8
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Ricordati che oltre al database Alfresco necessita anche di una porzione di file system in cui andranno a crearsi tutti i contenuti binari e gli indici di ricerca che gli utenti caricheranno nel sistema, questa sezione di filesystem va configurata sempre con un path assoluto con la property dir.root.

Una volta completata la configurazione del file di properties, potrai far partire Alfresco che alla prima esecuzione creerà automaticamente tutte le tabelle all'interno del database e tutta la struttura del repository all'interno del filesystem andando a creare tutti i contenuti di default necessari per il funzionamento del sistema.

Spero ti possa aiutare

Sei stato molto chiaro e ti ringrazio molto.

Sicuramente mi sarà molto utile.
grazie ancora

Un altra piccola domanda. Il driver per il DB MYSQL va scaricato o è già integrato nella versione community 4.0?
Grazie mille anticipatamente.

openpj · ‎17 Feb 2012

Alfresco nel package della versione community include solamente il driver per Postgresql.

Il driver JDBC di MySQL lo puoi scaricare direttamente dal seguente indirizzo:
http://dev.mysql.com/downloads/connector/j/

Una volta scaricato lo puoi copiare all'interno delle librerie condivise dell'application server.

Grazie mille per la tempestività

Ho installato tutta la configurazione di alfresco, ma quando provo a farlo partire si connette correttamente al db ma va in PermGen Space dando prima quest'errore :

Assicurati di settare i parametri della JVM nel modo consigliato dalla wiki:
http://wiki.alfresco.com/wiki/JVM_Tuning#General_Case

salvatore_conta · ‎20 Feb 2012

Ho risolto il problema e fatto partire finalmente Alfresco. Ho un altra domanda che probabilmente richiederebbe l'apertura di un nuovo post, ma la faccio comunque chissà che qualcuno riesca ad illuminarmi. Come faccio a cominciare a scaricare, integrare e sviluppare funzionalità customizzate su Alfresco?
Grazie anticipatamente

Ciao Salvatore,

la tua è una bella domanda molto aaaaaaaaaaampia che riguarda la personalizzazione di Alfresco

…se indichi cosa più o meno vorresti estendere ( mi riferisco ai webscript, ai moduli, al lato client, alle action, ecc ) ti linko delle buone risorse per iniziare ad apprendere lo strumento.

Intanto ti linko l'SDK di Alfresco http://wiki.alfresco.com/wiki/Community_file_list_4.0.d, la trovi in fondo alla pagina, da lì puoi vedere dei buoni esempi.

Poi ti consiglio il libro di Piergiorgio Lucidi e Ugo Cei http://www.open4dev.com/book/ veramente ben fatto e utilissimo (almeno per me

) se si vogliono apprendere i meccanismi di integrazione di Alfresco.

Spero ti possa essere di aiuto
