2.修改配置文件

mkdir /opt/clamav/share/update
touch /opt/clamav/logs/{freshclam.log,clamd.log}
chown -R clamav:clamav /opt/clamav/logs
chown clamav.clamav /opt/clamav/share/updatecp /opt/clamav/etc/clamd.conf.sample /opt/clamav/etc/clamd.conf

# 会有点慢，多台机器的话，可以一台下载之后再拷贝,下载的文件在 /opt/clamav/share/clamav 目录
/opt/clamav/bin/freshclam

tar zxf clamav.virus_data.tar.gz
cp clamav/* /opt/clamav/share/clamav/### 添加定时扫描任务
mkdir /tmp/virus_collection
echo "#scan virus" >>/etc/crontab
