There are several ways to install Razor-Agent. Two common ways are listed below:

Yum / RPM package:

The perl-Razor-Agent is available through Dag Wiers apt/yum repository:

You will need to configure yum to use Dag Wiers repository for your Release and Architecture which is outside the scope of this document (google rpmforge-release). Enable Dag's repository and append the following line to Dag's repository section:

includepkgs=perl-Razor-Agent perl-Digest-HMAC perl-Digest-SHA1 perl-Net-DNS perl-Net-IP razor-agents

Install the Razor-Agnet and its dependencies:

yum install perl-Razor-Agent razor-agents

Alternatively you can download the specific packages directly from Dag's mirrors and install manually with the rpm command. The downside is you are not notified if there is a patch or update to these packages.


Compile:

As root: Get razor-agents-sdk from razor.sourceforge.net, untar it and

perl Makefile.PL
make
make install

Also get razor-agents from razor.sourceforge.net, untar it and

perl Makefile.PL
make
make install

Open your firewall ports for razor2 (TCP/2703 outgoing).


Configuring Razor:

mkdir /opt/zimbra/amavisd/.razor; chown -Rf zimbra:zimbra /opt/zimbra/amavisd/.razor

As zimbra user, create your razor account:

razor-admin -home=/opt/zimbra/amavisd/.razor -create
razor-admin -home=/opt/zimbra/amavisd/.razor -discover
razor-admin -home=/opt/zimbra/amavisd/.razor -register
