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-0.101.0.tar.gz
cd clamav-0.101.0
./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 /
