Linux 下杀毒软件 clamav 0.104.2 离线安装及测试(CentOS7)
1.下载安装
clamav 官网下载 clamav-0.104.2.linux.x86_64.rpm

 

 

 将该文件上传至服务器,安装命令如下:

rpm -ivh --prefix=/usr/local/clamav clamav-0.104.2.linux.x86_64.rpm

2. 配置

   添加用户组和组成员

groupadd clamav
useradd -g clamav clamav

创建日志目录和病毒库目录

    mkdir -p /usr/local/clamav/logs
    mkdir -p /usr/local/clamav/update

创建日志文件

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

文件授权

chown clamav:clamav /usr/local/clamav/logs/clamd.log
chown clamav:clamav /usr/local/clamav/logs/freshclam.log
chown clamav:clamav /usr/local/clamav/update

 修改配置文件

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

文件1:clamd.conf

vim /usr/local/clamav/etc/clamd.conf
#Example  //注释掉这一行
#添加以下内容
LogFile /usr/local/clamav/logs/clamd.log
PidFile /usr/local/clamav/update/clamd.pid
DatabaseDirectory /usr/local/clamav/update

文件2:freshclam.conf

vim /usr/local/clamav/etc/freshclam.conf
#Example  //注释掉这一行
#添加以下内容
DatabaseDirectory /usr/local/clamav/update
UpdateLogFile /usr/local/clamav/logs/freshclam.log
PidFile /usr/local/clamav/update/freshclam.pid

将这两个文件复制一下:

cp /usr/local/clamav/etc/*.conf /usr/local/etc/

3. 运行

    1. 下载病毒库文件并上传到目录 /usr/local/clamav/update

      main.cvd
      daily.cvd
      bytecode.cvd

      注:也可以在有网络的机器上运行如下命令更新病毒库:

      /usr/local/clamav/bin/freshclam

      2.配置库文件路径

      vim /etc/ld.so.conf

      追加一行:

      /usr/local/clamav/lib64

      更新生效:

      ldconfig

      如果最后运行时仍然报错:

      clamscan: error while loading shared libraries: libclamav.so.9: cannot open shared object file: No such file or directory

      则说明配置没有生效。

      3.创建命令软件链接

      ln -s /usr/local/clamav/bin/clamscan /usr/local/bin/clamscan

      运行使用

    • 卸载程序

    1. rpm remove clamav

       

      clamscan -r --bell -i 路径  杀毒
      
      clamscan -r –remove 路径  扫描并清除
      
      clamscan -r --bell -i /opt/1/ --move /tmp/     扫描并移动病毒和感染文件到指定目录
      
      -r 递归扫描子目录
      -i 筛选感染文件
      –bell 病毒检测的侦查
      –copy 目录 将受感染的文件复制到目录

      ClamAV扫描病毒

       ##扫描文件
      clamscan targetfile
      ##递归扫描home目录,并且记录日志
      clamscan -r -i /home  -l  /var/log/clamscan.log
      ##递归扫描home目录,将病毒文件删除,并且记录日志
      clamscan -r -i /home  --remove  -l /var/log/clamscan.log
      ##建议##扫描指定目录,然后将感染文件移动到指定目录,并记录日志
      clamscan -r -i /home  --move=/opt/infected  -l /var/log/clamscan.log

      周期自动扫描病毒

      ##每天凌晨11点进行文件扫描
      crontab -e
      0 23 * * * root  /usr/local/bin/clamscan.sh
      ##配置扫描文件
      vim /usr/local/clamscan.sh
      clamscan -r -i /home  --move=/opt/infected  -l /var/log/clamscan.log
