ClamAV：未在 ubuntu 上创建 clamd.ctl 文件

Question

我有 ubuntu 16.04.6 版本，我正在尝试安装并运行clamdscan它以检查防病毒软件。

我使用了他们网站中给出的安装说明。IE。

sudo apt-get install clamav
sudo apt-get install clamav-daemon

以上 2 个命令工作正常。但是当我尝试通过运行命令下载定义（我假设在上述之后是强制性的）时

sudo freshclam

它未能引发以下错误：

^Clamd was NOT notified: Can't connect to clamd through /var/run/clamav/clamd.ctl: No such file or directory

根据这个接受的答案，安装后应该创建该文件，clamav-daemon但显然这不会发生。

Answer 1

我在Ubuntu 20.04 LTS机器上遇到了这个问题，

我所做的是：

1. 跑 sudo systemctl stop clamav-daemon.service
2. 然后运行sudo rm /var/log/clamav/freshclam.log（有时它会被锁定）
3. 启动服务 sudo systemctl start clamav-daemon.service

以确保一切正常运行sudo systemctl status clamav-daemon.service，输出应如下所示：

?  ~ sudo systemctl status clamav-daemon.service
? clamav-daemon.service - Clam AntiVirus userspace daemon
     Loaded: loaded (/lib/systemd/system/clamav-daemon.service; enabled; vendor preset: enabled)

             man:clamd.conf(5)
             https://www.clamav.net/documents/

             ??6138 /usr/sbin/clamd --foreground=true

May 03 05:03:51 user systemd[1]: Starting Clam AntiVirus userspace daemon...
May 03 05:03:51 user systemd[1]: Started Clam AntiVirus userspace daemon.

现在运行sudo freshclam并检查日志文件（或控制台输出）

Sun May  3 05:04:02 2020 -> --------------------------------------
Sun May  3 05:04:02 2020 -> ClamAV update process started at Sun May  3 05:04:02 2020

享受！

Answer 2

我发现运行后：

freshclam 

并得到这个错误：

Clamd was NOT notified: Can't connect to clamd through /var/run/clamav/clamd.ctl: No such file or directory

你只需要为恶魔运行重启：

service clamav-daemon restart

然后freshclam 再一次，一切正常。

Answer 3

为 ClamAV 添加 sock 文件：

sudo touch /var/lib/clamav/clamd.sock
sudo chown clamav:clamav /var/lib/clamav/clamd.sock

然后，编辑/etc/clamav/clamd.conf- 取消注释此行：

LocalSocket /var/lib/clamav/clamd.sock

保存文件并重新启动clamav-daemon.service

另一个错误：

sudo freshclam

为 ClamAV 添加 sock 文件：

sudo touch /run/clamav/clamd.sock
sudo chown clamav:clamav /run/clamav/clamd.sock

sudo systemctl restart clamav-daemon.service
sudo freshclam

就是这样。
