yum安装

wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo　　##epel源
yum install -y clamav

编译安装

1.安装依赖环境

yum install -y zlib openssl-devel
yum groupinstall -y "Development Tools"

apt install -y zlib1g zlib1g.dev openssl vim build-essential libssl-dev  #ubuntu/debian安装

2.安装clamav软件包

wget http://www.clamav.net/downloads/production/clamav-0.101.0.tar.gz
tar zxvf clamav-0.101..tar.gz
cd clamav-0.101.
./configure --prefix=/usr/local/clamav
make && make install

3.修改配置文件

cp /usr/local/clamav/etc/clamd.conf.sample /usr/local/clamav/etc/clamd.conf
sed -i '8s/Example/#Example/g' /usr/local/clamav/etc/clamd.conf
echo 'LogFile /usr/local/clamav/logs/clamd.log' >> /usr/local/clamav/etc/clamd.conf
echo 'PidFile /usr/local/clamav/updata/clamd.pid' >> /usr/local/clamav/etc/clamd.conf
echo 'DatabaseDirectory /usr/local/clamav/updata/clamav' >> /usr/local/clamav/etc/clamd.conf

cp /usr/local/clamav/etc/freshclam.conf.sample /usr/local/clamav/etc/freshclam.conf
sed -i '8s/Example/#Example/g' /usr/local/clamav/etc/freshclam.conf
echo 'DatabaseDirectory /usr/local/clamav/updata' >> /usr/local/clamav/etc/freshclam.conf
echo 'UpdateLogFile /usr/local/clamav/logs/freshclam.log' >> /usr/local/clamav/etc/freshclam.conf
echo 'PidFile /usr/local/clamav/updata/freshclam.pid' >> /usr/local/clamav/etc/freshclam.conf

4.创建用户

groupadd clamav
useradd -g clamav clamav

5.创建目录文件

mkdir /usr/local/clamav/logs
mkdir /usr/local/clamav/updata

touch /usr/local/clamav/logs/freshclam.log
chown clamav:clamav /usr/local/clamav/logs/freshclam.log
touch /usr/local/clamav/logs/clamd.log
chown clamav:clamav /usr/local/clamav/logs/clamd.log
chown clamav:clamav /usr/local/clamav/updata

6.升级病毒库（需要服务器连通外网）

/usr/local/clamav/bin/freshclam

7.扫描病毒

/usr/local/clamav/bin/clamscan -r --bell -i /

clamscan常用参数

-r/--recursive[=yes/no]	所有文件
--log=FILE/-l FILE	增加扫描报告
clamscan -l /var/log/clamscan.log /
--move [路径]	移动病毒文件至
--remove [路径]	删除病毒文件
--quiet	只输出错误消息
--infected/-i	只输出感染文件
--suppress-ok-results/-o	跳过扫描OK的文件
--bell	扫描到病毒文件发出警报声音
--unzip(unrar)	解压压缩文件扫描
