RockyLinux8安装ClamAV

1、官网下载rpm包

cd /tmp
wget https://www.clamav.net/downloads/production/clamav-1.4.1.linux.x86_64.rpm

2、安装

rpm -ivh clamav-1.4.1.linux.x86_64.rpm

3、创建目录

#创建病毒数据库和日志目录
mkdir -p /data/clamav/db
mkdir -p /data/clamav/logs
#创建日志文件
touch /data/clamav/logs/clamd.log
touch /data/clamav/logs/freshclam.log

#权限设置
useradd clamav
chown -R clamav:clamav /data/clamav/logs/freshclam.log
chown -R clamav:clamav /data/clamav/db

 4、配置文件修改

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

vim clamd.conf
#Example  注释掉
#下方内容添加至conf中
LogFile /data/clamav/logs/clamd.log
PidFile /data/clamav/clamd.pid
DatabaseDirectory /data/clamav/db
LogRotate yes
TCPSocket 23310
TCPAddr 0.0.0.0

vim freshclam.conf
#Example  注释掉
#下方内容添加至conf
DatabaseDirectory /data/clamav/db
UpdateLogFile /data/clamav/logs/freshclam.log
PidFile /data/clamav/db/freshclam.pid
LogRotate yes

5、下载病毒库

freshclam

6、启动Clamd服务

vim /etc/systemd/system/clamd.service

[Unit]
Description=Clam AntiVirus Daemon
After=network.target

[Service]
Type=forking
ExecStart=clamd
ExecReload=kill -HUP $MAINPID
Restart=on-failure
RestartSec=5

[Install]
WantedBy=multi-user.target

systemctl enable clamd.service

systemctl start clamd.service

systemctl status clamd.service

7、使用C#客户端连接

  <PackageReference Include="nClam" Version="9.0.0" />

     var clam = new ClamClient("localhost", 23310)
     {
         MaxStreamSize = 100 * 1024 * 1024 //100MB
     };
      var scanResult = await clam.SendAndScanFileAsync(@"D:\text.txt"); 
     Console.WriteLine(scanResult.Result switch
     {
         ClamScanResults.Clean => "The file is clean!",
         ClamScanResults.VirusDetected => $"Virus Found! Virus name: {scanResult.InfectedFiles?.First()?.VirusName}",
         ClamScanResults.Error => $"Woah an error occured! Error: {scanResult.RawResult}",
         _ => "Unknown result"
     });
