[شرح] تركيب Clam AntiVirus مضاد الفيروسات !

[alktheri]

السلام عليكم ورحمة الله وبركاته

برنامج clamav هو مضاد فيروسات يستخدم علي Linux

wget -c http://downloads.sourceforge.net/clamav/clamav-0.93rc1.tar.gz 

tar −xvzf clamav-0.93rc1.tar.gz
cd clamav−0.93 #groupadd clamav
useradd clamav −g clamav −c "Clam AntiVirus" −s /nonexistent .
/configure
make
make install
cd .. 

نقوم بالتعديل علي /etc/crontab لعمل تحديث كل 12 ساعه للـ Clam عن طريق الامر التالي :

pico /etc/crontab 

اضف في نهايته هذا السطر :

0 12 * * * root /usr/local/bin/clamscan 

لتنفيذ التحديث استخدم الاوامر التاليه :

touch /var/log/clam-update.log
chmod 600 /var/log/clamupdate.log
chown clamav /var/log/clamupdate.log 

نقوم بعمل تحديث للـ freshclam

freshclam -d -c 6 -l /var/log/clam-update.log 

لاعداد البرنامج اتبع الخطوات التاليه :

pico /etc/clamd.conf 

قم بتنفيذ المتغيرات التاليه :

Uncomment "LogSyslog"
Uncomment "StreamSaveToDisk"
Uncomment "MaxThreads" and change value to "30"
Uncomment "User" and change value to "qscand"
Uncomment "Foreground"
Uncomment "ScanMail" 

نفذ امر انشاء الملف التالي :

mkdir -p /usr/local/clamav/bin 

ونقوم بعمل سكربت صغير لتشغيل و اغلاق البرنامج :

pico /usr/local/clamav/bin/clamdctl 

#!/bin/sh
 
# For Red Hat chkconfig
# chkconfig: - 80 30
# description: the ClamAV clamd daemon
 
PATH=/usr/local/clamav/bin:/bin:/usr/bin:/usr/local/bin:/usr/local/sbin
export PATH
 
case "$1" in
  start)
    echo "Starting clamd"
    if svok /service/clamd ; then
      svc -u /service/clamd
    else
      echo clamd supervise not running
    fi  
    if [ -d /var/lock/subsys ]; then
      touch /var/lock/subsys/clamd
    fi
    ;;
  stop)
    echo "Stopping clamd..."
    echo "  clamd"
    svc -d /service/clamd
    if [ -f /var/lock/subsys/clamd ]; then
      rm /var/lock/subsys/clamd
    fi
    ;;
  stat)
    svstat /service/clamd
    svstat /service/clamd/log
    ;;
  restart)
    echo "Restarting clamd:"
    echo "* Stopping clamd."
    svc -d /service/clamd
    echo "* Sending clamd SIGTERM and restarting."
    svc -t /service/clamd
    echo "* Restarting clamd."
    svc -u /service/clamd
    ;;
  hup)
    echo "Sending HUP signal to clamd."
    svc -h /service/clamd
    ;;
  help)
    cat <<HELP
   stop -- stops clamd service (smtp connections refused, nothing goes out)
  start -- starts clamd service (smtp connection accepted, mail can go out)
   stat -- displays status of clamd service
restart -- stops and restarts the clamd service
    hup -- same as reload
HELP
    ;;
  *)
    echo "Usage: $0 {start|stop|stat|restart|hup|help}"
    exit 1
    ;;
esac
 
exit 0 

نقوم بأضافه التصريحات التاليه :

chmod 755 /usr/local/clamav/bin/clamdctl 

chown clamav /usr/local/clamav/bin/clamdctl 

ln -s /usr/local/clamav/bin/clamdctl /usr/local/bin 

انشأ المجلد التالي :

mkdir -p /usr/local/clamav/supervise/clamd/log 

حرر الملف :

pico /usr/local/clamav/supervise/clamd/run 

قم بأضافه التالي في الملف :

#!/bin/sh

Create the /usr/local/clamav/supervise/clamd/log/run file:

#!/bin/sh
exec /usr/local/bin/setuidgid qscand /usr/local/bin/multilog t /var/log/clamd 

قم بعمل التصريحات التاليه :

chmod 755 /usr/local/clamav/supervise/clamd/run 

chmod 755 /usr/local/clamav/supervise/clamd/log/run 

نقوم بعمل مجلد الـ log

mkdir -p /var/log/clamd 

chown qscand /var/log/clamd 

نقوم بأضافه supervise فى service

ln -s /usr/local/clamav/supervise/clamd /service 

لايقاف البرنامج عن طريق الامر التالي :

clamdctl stop 

لتشغيل البرنامج عن طريق الامر التالي :

clamdctl start
