Note : The configuration below assumes you have installed ClamAV using the RPM I've provided. If you install via source, you may need to tweak some of the permissions on the directories. If someone wants to write up detailed documentation for the source install, I'd be more than happy to post it and give credit.
  • Starting clamd and freshclam
Just like spamassassin, we want to make sure that clamd and freshclam (the virus definition updater) are set to start on a reboot. I'm assuming an RPM install here, see the clamav documentation for other options.
rootshell> chkconfig --list clamd
clamd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
rootshell> chkconfig --list freshclam
freshclam 0:off 1:off 2:off 3:off 4:off 5:off 6:off
rootshell> chkconfig clamd on
rootshell> chkconfig freshclam on
rootshell> chkconfig --list clamd
clamd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
rootshell> chkconfig --list freshclam
freshclam 0:off 1:off 2:on 3:on 4:on 5:on 6:off
rootshell> service clamd start
Starting clamd: [ OK ]
rootshell> service freshclam start
Starting freshclam: [ OK ]
