Tue, 12 Mar 2024 17:36:15 +0800

安裝

## Debian
sudo apt-get update
sudo apt-get install clamav clamav-daemon

## Centos
sudo yum install epel-release
sudo yum install clamav clamav-update

配置

# 如果日志文件不存在的話，需要手動創建。

sudo touch /var/log/clamav/freshclam.log
sudo chown clamav:clamav /var/log/clamav/freshclam.log
sudo chmod 644 /var/log/clamav/freshclam.log

使用

安裝之後，需要重啓一下機器，否則啓動服務不生效（至少我操作的時候是這樣的）。

啓動服務

sudo systemctl start clamav-daemon
# 或者
sudo systemctl restart clamav-daemon
