Installer freezed while setting cron

[jilingshu]

hi there,
I bought Dreamhost VPS and tried to install the latest Zimbra 6 on it. The installer goes well until it said 'Setting cron job'. When it came here, it would freezed. If I use Ctrl-C to interrupt it, the Zimbra would not work and I can found all services are down in Administration Console. And also, the Administration Console worked incorrectly, if I select Servers->ps37575.dreamhostps.com, it would give me a error

Message: system failure: server ps37575.dreamhostps.com
zimbraRemoteManagementPrivateKeyPath (/opt/zimbra/.ssh/zimbra_identity) does not exist Error code: service.FAILURE Method: GetCertRequest Details:soap:Receiver

What shall I do? thx
