尝试在远程虚拟机上设置 Apache。无法从我的机器访问

因此，我在一台我无法物理访问的 centos 7 虚拟机上设置了 httpd 和 iptables。如果我运行，curl http://localhost我会得到一堆 html，但如果我在 chrome 中输入虚拟机的 ip 地址（我曾经用 ssh 进入它），请求就会超时。我httpd.conf在示例中保留了文件原样，但我将/etc/sysconfig/iptables文件修改为：

# sample configuration for iptables service
# you can edit this manually or use system-config-firewall
# please do not ask us to add additional ports/services to this default configuration
*filter

尝试适应 ftp 服务器和 httpd。我应该在哪里寻找我的服务器？

此外，我已经将其删除，firewalld因此不会产生问题。

编辑：iptables -nvL制作：

看起来您实际上正在使用firewalld。在这种情况下，/etc/sysconfig/iptables将忽略，并使用配置firewalld firewall-cmd。

只需告诉firewalld添加您想要的服务就足够了。

firewall-cmd --add-service=http --add-service=https --add-service=ftp

如果您对结果满意，您可以保存它们：

firewall-cmd --runtime-to-permanent

您可以在以下位置了解有关如何使用firewalld的更多信息Red Hat 文档。
