linux下ClamAV使用

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)
<ignore_js_op> 
第三步：编译安装
tar xfclamav-0.99.2.tar.gz
cdclamav-0.99.2
<ignore_js_op> 
安装依赖包
yuminstall gcc openssl openssl-devel  -y
<ignore_js_op> 
./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
