在 Ubuntu Server 22.04 中对 Apache2 进行故障排除

sudo apt update当尝试使用和更新我的系统时sudo apt upgrade，Apache2 抛出错误并阻止我的系统更新：

Setting up apache2 (2.4.52-1ubuntu4.1) ...

正如 Jos 指出的那样，它javascript-common说不存在，但是当我尝试按照他的建议安装它时，它却说不是这样：

$ sudo apt install javascript-common

javascript-common is already the newest version (11+nmu1).

以下是我能想到的所有输出，但我确信还有更多信息可以找到。不幸的是，我对终端界面还很陌生，我不确定在哪里可以找到故障排除信息。

$ apache2 -v
Server version: Apache/2.4.52 (Ubuntu)
Server built:   2022-06-14T12:30:21

$ apache2 -t
[Tue Aug 23 07:45:27.890824 2022] [core:warn] [pid 921747] AH00111: Config variable ${APACHE_RUN_DIR} is not defined
apache2: Syntax error on line 80 of /etc/apache2/apache2.conf: DefaultRuntimeDir must be a valid directory, absolute or relative to ServerRoot

当我尝试运行调试时，我也收到上述相同的消息：

$ apache2 -X
[Tue Aug 23 07:50:00.684706 2022] [core:warn] [pid 922041] AH00111: Config variable ${APACHE_RUN_DIR} is not defined
apache2: Syntax error on line 80 of /etc/apache2/apache2.conf: DefaultRuntimeDir must be a valid directory, absolute or relative to ServerRoot

当我导航到 时/etc/apache2/apache2.conf，第 80 行显示以下内容：DefaultRuntimeDir ${APACHE_RUN_DIR}

任何帮助解决此问题的帮助都将不胜感激！如果有帮助的话，该系统上 apache2 的目的是托管 Bitwarden 密码管理器的 Web 服务器。

问题出现的时候其实是升级到 8.1 的时候 php7.4 残留文件导致的错误，需要删除的残留文件是 php7.4.load 和 php7.4.conf。

为了删除它们，我运行了： sudo find /etc/apache2 -name "php7.4*" -delete 从 /etc/apache2/mods-available 和 /etc/apache2/mods-enabled 中删除了 php7.4.load 和 php7.4.conf。

我还删除了 /etc/php/7.4，因为它不再安装。

----编辑---- 为了修复 javascript-common 问题，我刚刚清除并重新安装了该包sudo apt purge javascript-common; sudo apt install javascript-common

我收到此错误是因为更新出于某种原因安装了 Apache，尽管我已经安装了 Nginx。解决方法是简单地删除所有 Apache 包：

sudo apt remove apache2
sudo apt autoremove

然后，如果您确定没有使用 Apache 配置任何重要内容，则可以删除 Apache 配置目录/etc/apache2。请务必/etc/apache2/sites-available先检查目录。
