我正在运行一个使用共享ip的多个网站的本地web服务器。最近我升级到Ubuntu22.04.1LTS，我刚刚发现我的网站只有一个正常工作。我不能肯定这个问题在升级的时候不存在，但是不久之前它还在工作。

etc/hosts

192.168.1.29    secondbase  
192.168.1.29    mattiefernworrix.lan  
192.168.1.29    mfwsandbox  
192.168.1.29    pinkpoodle  
192.168.1.29    mfwx

secondbase是服务器名。

mattiefernworrix.lan运行良好，是列表中的第一个。其他三种(mfwsandbox、pinkpoodle和mfwx)则不然。事实上，这不是完全正确的。如果我请求一个静态html页面，它就会如预期的那样出现。如果我请求一个.php文件，那么它在503消息中失败。php文件都从mysql db获取数据。

因此，据我所知，httpd没有运行。

jking@secondbase:/sbin$ systemctl status httpd
Unit httpd.service could not be found.

因此，我试图安装httpd，但失败了。

sudo apt-get update  
sudo apt-get install httpd

Package httpd is a virtual package provided by:

  nginx-full 1.18.0-6ubuntu14.1  
  nginx-extras 1.18.0-6ubuntu14.1  
  nginx-core 1.18.0-6ubuntu14.1  
  apache2 2.4.52-1ubuntu4.1  
  yaws 2.1.1+dfsg-1  
  webfs 1.21+ds1-12  
  tntnet 2.2.1-4build2  
  mini-httpd 1.30-2build1  
  micro-httpd 20140814-2.1  
  lighttpd 1.4.63-1ubuntu3  
You should explicitly select one to install.

E: Package 'httpd' has no installation candidate

最后，我尝试安装apache2包。

jking@secondbase:/sbin$ sudo apt-get install apache2

apache2 is already the newest version (2.4.52-1ubuntu4.1).

不知道从这里往哪里走。卸载apache2，然后再安装它？

任何帮助都是非常感谢的。

谢谢你的回应。

我找到了之前的帖子

phpmyadmin“503服务不可用”：Unbuntu20.04，MySQL8.0

弄明白了。如果其他人有此问题，我必须将以下块添加到我的子域VirtualHost中，phpmyadmin将再次显示在子域中： SetHandler / <D9FilesMatch>

我看过了，而且没有/var/run/php/目录。

jking@secondbase:~$ php -v  
PHP 8.1.2 (cli) (built: Jul 21 2022 12:10:37) (NTS)

附加问题症状

嗨，我刚刚意识到，我说的是唯一的工作网站只有html文件，没有php文件。我添加了info.php文件并得到了503个响应。因此，所服务的所有站点都无法处理php文件并使用503错误消息进行响应。

检查libasache2-mod-php

除了升级到22.04之外，我什么也没做。我以为它会被更新，因为它是一个现有的安装(包)。我做这个假设是错的吗？这一切都是在升级之前开始的。从那以后，我还运行了很多次apt-获取更新。

检查它：

jking@secondbase:~$ dpkg -s libapache2-mod-php  
Package: libapache2-mod-php  
Status: install ok installed  
Priority: optional  
Section: php  
Installed-Size: 18  
Maintainer: Ubuntu Developers   
Architecture: all  
Source: php-defaults (92ubuntu1)  
Version: 2:8.1+92ubuntu1  
Depends: libapache2-mod-php8.  
Description: server-side, HTML-embedded scripting language (Apache 2 module) (default)

 This package provides the PHP module for the Apache 2 webserver.

 PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.

 This package is a dependency package, which depends on latest stable
 PHP version (currently 8.1).

Original-Maintainer: Debian PHP Maintainers

版本错配？

因此，错误消息是指php7.4 /run/php/php7.4-fpm.sock (*) failed，而dpkg是指php8.1 Version: 2:8.1+92ubuntu1。有什么需要更新的吗？还是需要卸载/删除的东西？

约翰

不幸的是，并没有明显的不同。仍然在抱怨error.log文件中的PHP7.4：

[Sun Aug 28 23:23:44.600963 2022] [proxy:error] [pid 6221] (2)No such file or directory: AH02454: FCGI: attempt to connect to Unix domain socket /run/php/php7.4-fpm.sock (*) failed

我仍然没有/run/php目录。

不知道从这里往哪里走。我可能会卸载apache并重新安装。

感谢你的努力。谢谢。
