回帖：systemctl list-unit-files --type=service
一、yum安装
安装后会自动生成服务文件，启动服务后，可使用clamdsacn命令，扫描速度快；
启动服务后，会实时监控扫描连接，虽然安全性高了，不过可能会对服务器性能有影响；

yum install clamavclamav-server clamav-data clamav-update clamav-filesystem clamav-scanner-systemd clamav-devel clamav-lib clamav-server-systemd pcre* gcc zlib zlib-devel libssl-devel libssl openssl
这种方法安装后，病毒库默认地址是/var/lib/clamav。
chown -R clamav.clamav /usr/local/clamav/
systemctl start clamav-freshclam.service
systemctl enable clamav-freshclam.service
systemctl status clamav-freshclam.service

#先停止freshclam
systemctl stop clamav-freshclam.service
#再更新
/usr/local/clamav/bin/freshclam（根据网络质量确定更新时长）
