本文详细介绍如何在Linux操作系统的VPS环境下搭建ClamAV病毒扫描系统，指导用户有效进行病毒扫描，确保网站安全。内容包括安装ClamAV、配置病毒数据库更新及扫描任务，为网站提供坚实的防护。
本文目录导读：
随着互联网的普及，网络安全问题日益凸显，对于网站和服务器来说，病毒和恶意软件的威胁不容忽视，ClamAV 是一款开源的病毒扫描软件，它具有强大的病毒检测能力，能够有效保护服务器安全，本文将详细介绍如何在 VPS 环境下搭建 ClamAV 病毒扫描系统。
VPS 环境准备
1、选择合适的 VPS 服务商：选择具有良好性能和稳定性的 VPS 服务商，如阿里云、腾讯云等。
2、准备操作系统：本文以 CentOS 7 为例，确保操作系统已更新到最新版本。
3、配置防火墙：确保 VPS 的防火墙配置正确，只开放必要的端口。
安装 ClamAV
1、更新系统软件包
yum update -y
2、安装 ClamAV 相关软件包
yum install clamav clamav-update clamav-filesystem clamav-scanner clamav-scanner-systemd clamav-milter -y
3、启动 ClamAV 服务
systemctl start clamav-daemon systemctl enable clamav-daemon
4、更新病毒库
freshclam
配置 ClamAV
1、修改 ClamAV 配置文件
vi /etc/clamd.conf
在配置文件中，取消以下行的注释：
