Zarafa migratie van Connectux naar SYN-3

Users

Zorg dat de users zijn aangemaakt op de SYN-3 server.

Als de installatie te groot is om dit handigmatig te doen, neem dan contact op met ons. Wij kunnen hiervoor scripts maken.

Database kopieren van Connectux naar SYN-3

  • Zorg dat u mimimaal SYN-3 versie 4.4.1 hebt.
  • Achterhaal de mysql user en pass van de database op de Connectux server:
    linux:/md0 # grep mysql /etc/araneus/zarafa/server.cfg
    mysql_user              = root
    mysql_password          = 12345
    mysql_database          = zarafa
    
  • Zorg dat de Zarafa database op de SYN-3 server leeg is:
    [Syn-3] root@syn.kado.local ~# svcstop /service/zarafa-server/                                                                                                                               
    Stopping /service/zarafa-server/ ....OK
    [Syn-3] root@syn.kado.local ~#  mysqladmin -f -p`cat /etc/my.passwd` drop zarafa && mysqladmin -p`cat /etc/my.passwd` create zarafa                                                                                         
    Database "zarafa" dropped
    [Syn-3] root@syn.kado.local ~# 
    
    
  • Om tijd te besparen, zorgen we dat de database rechtstreeks geïmporteerd word op de SYN-3 server, zonder tussenkomt van tijdelijke files. Voer uit op de Connectux server:
linux:/md0 # mysqldump --quick -uroot -p'12345' zarafa | ssh root@10.0.0.6 'mysql -p`cat /etc/my.passwd` zarafa'
root@10.0.0.6's password:
  • Afhankelijk van de database grote, kan dit soms een paar uur duren. Met dstat en top kunt u op de syn3 server zien wat er gaande is.

Mocht de conversie onderbroken worden met de melding 'ERROR 1153 (08S01) at line 24818: Got a packet bigger than 'max_allowed_packet' bytes', dan dient u deze instelling hoger te maken in beide mysql config files

User ID's en database conversie

Kopieer de passwd file van de oude server naar /root en gebruik dit script
