第一步：Clamav下载

http://www.clamav.net/downloads

#yuminstall wget –y

第二步：创建clamav用户和组

groupaddclamav   (创建clamav组)

useradd-g clamav clamav(创建clamav用户并加入clamav组)

第三步：编译安装

tar xfclamav-0.99.2.tar.gz

cdclamav-0.99.2

安装依赖包

yuminstall gcc openssl openssl-devel  -y

./configure--prefix=/usr/local/clamav

make&&make install

第四步：配置

mkdir /usr/local/clamav/logs      (日志存放目录)

touch /usr/local/clamav/logs/clamd.log

touch /usr/local/clamav/logs/freshclam.log

mkdir /usr/local/clamav/updata   (clanav 病毒库目录)

chown  -R root.clamav /usr/local/clamav/

chown -R clamav.clamav /usr/local/clamav/updata/

chown clamav.clamav /usr/local/clamav/logs/clamd.log

chown clamav.clamav /usr/local/clamav/logs/freshclam.log

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.

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.

DatabaseDirectory /usr/local/clamav/updata

UpdateLogFile /usr/local/clamav/logs/freshclam.log

PidFile /usr/local/clamav/updata/freshclam.pid

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

第五步：升级病毒库

/usr/local/clamav/bin/freshclam

这个过程很久，大概半个小时。可以开启screen来进行。

/usr/local/clamav/bin/clamscan--remove (查杀当前目录并删除感染的文件)

注意:确保网络正常

第六步：计划任务

实际生产环境应用

一般使用计划任务，让服务器每天晚上定时跟新和定时杀毒。保存杀毒日志，我的crontab文件如下

1  3  * **         /usr/local/clamav/bin/freshclam

30 3  * * *          /usr/local/clamav/bin/clamscan  --infected  -r /  --remove -l /var/log/clamscan.log
