Centos7下杀毒软件clamav的安装和使用

作者:互联网

一、yum安装

?
1 yum install clamav  clamav-server clamav-data clamav-update clamav-filesystem clamav-scanner-systemd clamav-devel clamav-lib clamav-server-systemd pcre* gcc zlib zlib-devel libssl-devel libssl openssl

这种方法安装后,病毒库默认地址是/var/lib/clamav。

二、编译安装

 2.1:下载软件包

#官网地址:
    http://www.clamav.net/downloads   
#Linux中下载地址:
    wget http://www.clamav.net/downloads/production/clamav-0.100.0.tar.gz
#参考文档:
https://github.com/vrtadmin/clamav-faq/raw/master/manual/clamdoc.pdf

2.2:创建clamav用户和存放病毒库目录

 #clamav用户和用户组
groupadd clamav && useradd -g clamav clamav && id clamav
#日志存放目录
mkdir -p /usr/local/clamav/logs     
touch /usr/local/clamav/logs/clamd.log
touch /usr/local/clamav/logs/freshclam.log
chown clamav.clamav /usr/local/clamav/logs/clamd.log
chown clamav.clamav /usr/local/clamav/logs/freshclam.log

#病毒存放目录
mkdir -p /usr/local/clamav/updata
chown -R root.clamav /usr/local/clamav/
chown -R clamav.clamav /usr/local/clamav/updata/

2.3:解压安装包

tar xf clamav-0.100.0.tar.gz

2.4:安装依赖

yum install gcc openssl openssl-devel  -y

2.5:编译安装

cd clamav-0.100.0/
./configure --prefix=/usr/local/clamav  --with-pcre
make && make install
echo $?

2.6:配置clamav

cd /usr/local/clamav/etc
cp clamd.conf.sample clamd.conf
cp freshclam.conf.sample freshclam.conf

vim clamd.conf
#Example    注释掉这一行.
添加下面三行:
LogFile /usr/local/clamav/logs/clamd.log    
PidFile /usr/local/clamav/updata/clamd.pid     
DatabaseDirectory /usr/local/clamav/updata
vim freshclam.conf
#Example    注释掉这一行. 
添加下面三行 
DatabaseDirectory /usr/local/clamav/updata
UpdateLogFile /usr/local/clamav/logs/freshclam.log
PidFile /usr/local/clamav/updata/freshclam.pid

2.7:启动clamav

chown -R clamav.clamav /usr/local/clamav/
systemctl start clamav-freshclam.service
systemctl enable clamav-freshclam.service
systemctl status clamav-freshclam.service

2.8:更新病毒库

#先停止freshclam
systemctl stop clamav-freshclam.service 
#再更新
/usr/local/clamav/bin/freshclam (根据网络质量确定更新时长)
或者
cd /usr/local/clamav/share/clamav wget http://database.clamav.net/main.cvd wget http://database.clamav.net/daily.cvd wget http://database.clamav.net/bytecode.cvd
  #更新完成启动
systemctl start clamav-freshclam.service
systemctl status clamav-freshclam.service


#创建软链接
ln -s /usr/local/clamav/bin/clamscan /usr/local/sbin/clamscan

说明:如果在手动更新病毒库的时候遇到错误,此时就要删除掉旧的镜像地址文件#rm -f /var/lib/clamav/mirrors.dat,再手动更新一次病毒库。

 

2.9:扫描杀毒

clamdscan:

clamdscan /usr

clamscan:

扫描参数:

#扫描所有文件并且显示有问题的文件的扫描结果
clamscan -r --bell -i /

#只显示找到的病毒信息
clamscan --no-summary -ri /tmp

#扫描home
clamscan --infected --remove --recursive /home

2.10:定时杀毒

#让服务器每天晚上定时更新和杀毒,保存杀毒日志,crontab文件如下:
1  3  * * *  /usr/local/clamav/bin/freshclam --quiet
20 3  * * *  /usr/local/clamav/bin/clamscan  -r /home  --remove -l /var/log/clamscan.log
