多个 IP 对应不同的域 Apache2

我以前曾设法做到这一点，没有任何问题，但现在我陷入困境。

我遇到了以下问题：我的 Ubuntu VPS 连接了两个 IP。111.111.11.111 和 222.222.22.222。111.111.111.111 是服务器的“默认”IP。222.222.22.222 是辅助 IP，我尝试将我的站点 example.com 添加到该 IP。奇怪的是，当我尝试浏览或 ping 我的 example.com 站点时，它会超时，无论是在域上还是在 IP 上，数据包丢失率 100%。

当我浏览 111.111.11.111 时，我到达了我的网站 example.com（显示内容），而该网站应该只显示在 222.222.22.222 上。为什么会发生这种情况？我错过了什么？

系统Ubuntu18.04 Apache2.4.29

  • 站点 000-默认已禁用。
  • 服务器上的所有网站文件都在 /var/www/example.com/public_html/ 中（如果我浏览，111.111.111.111 也会到达这里）

/etc/hosts

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        ServerAdmin webmaster@localhost

        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
RewriteEngine on
RewriteCond %{SERVER_NAME} =www.example.com [OR]

</VirtualHost>

编辑 1：首先查看 /etc/network/interfaces 得到了这个：

# ifupdown has been replaced by netplan(5) on this system.  See
# /etc/netplan for current configuration.
# To re-enable ifupdown on this system, you can run:
#    sudo apt install ifupdown

因此，当转到 /etc/netplan 时，会出现一个链接的 .yaml 文件，我在其中添加了 222.222.22.222 IP，现在它看起来像这样：

network:
    version: 2
    renderer: networkd
    ethernets:
        ens192:
            match:
                macaddress: '02:01:84:66:71:01'
            set-name: ens192
            gateway4: 111.111.11.111
            gateway6: '2a02:0750:0009:0000:0000:0000:0000:0001'
            addresses:
                - 111.111.11.111/23
                - '2a02:750:9::3c9/64'
                - 222.222.22.222/23
            nameservers:
                addresses:
                    - 33.33.3.300
                    - 33.33.3.301
                    - '2a02:751:aaaa::1'
                    - '2a02:751:aaaa::2'

完成此操作后，我可以 ping 和浏览 222.222.22.222。我想我会解决剩下的问题。谢谢你的帮助！

编辑 2：我以为我会解决其余的问题，但这里也遇到了困难。我可以通过所述 IP 访问该网站，但不能通过域名访问。尽管 Apache access.log 记录了每个尝试访问该网站的访问者。

为什么我会收到“连接被拒绝”的消息？

答案1

您不能使用<VirtualHost *:80>来实现此目的。如http://httpd.apache.org/docs/2.4/vhosts/ip-based.html“对于每个基于 IP 的虚拟主机，服务器必须具有不同的 IP 地址/端口组合”。该文档中还提供了如何正确执行此操作的示例。
