我已经阅读了与 Log4j 相关的安全漏洞。

如何检查我的服务器上是否安装了 Log4j？我的特定服务器使用Ubuntu 18.04.6 LTS.

我已经安装了许多第三方软件包，其中一些可能包含它。

是否有命令在我的服务器上运行以检查是否安装了 Log4j？

我正在使用 Ubuntu 18.04.1 LTS 配置新服务器（droplet）。我安装了 apache 并配置了虚拟主机。服务器名称是www.speedysoftware.com，这是 的值/etc/hostname。问题是，我试图将http://www.speedysoftware.com/重定向到特定的虚拟主机，但它被重定向到默认的虚拟主机。另一方面，http ://www.speedysoft.com/和http://www.speedy-software.com/被重定向到正确的虚拟主机，应该与http://www.speedysoftware 相同。 com/

<VirtualHost *:80>

    # 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.

可以看到http://www.speedy-soft.com/被重定向到默认的虚拟主机，这是正确的。配置有什么问题？

进行更改后，我重新加载了设置sudo systemctl restart apache2。

关于重定向，在这种情况下我不想重定向。我希望它们被视为独立的网站，尽管它们指向同一个虚拟主机。在其他情况下，我会重定向，例如我将http://www.speedypedia.org/重定向到http://www.speedypedia.info/，然后重定向http://ww.speedysoftware.com/（或任何其他子域，包括http://speedysoftware.com/）到http://www.speedysoftware.com/。

更新- 我检查了http://ww.speedysoftware.com/、http://www.speedysoftware.com/和http://speedysoftware.com/都指向正确的虚拟主机。只有http://www.speedysoftware.com/不会导致正确的虚拟主机。

我正在尝试设置一个 Ookla 服务器进行速度测试。我的操作系统是 Ubuntu（20.04 LTS），我安装了脚本，也将其设置为在重新启动后启动，但我不知道如何设置它以使用 HTTPS。测试页面说我的服务器通过了，netgauge但是失败了。我还想知道在将服务器上传到 Ookla 之前如何使用服务器进行速度测试？我想知道速度是多少以及它的性能如何。我在 Ookla 的网站上没有找到太多文档，例如我没有找到如何设置 HTTPS。如果我从 Let's encrypt 获得证书，如何安装和使用我的证书？websocketcrossdomainhttps

为了安装服务器，我点击了https://www.speedtest.net/speedtest-servers上的链接。
