Apache 不為本機提供服務

Question

我已經在 VMWare 託管的 Linux Mint 21 伺服器上設定了 Apache 伺服器，我已按照以下說明進行操作這個部落格運行多個 PHP 版本（7.4 和 8.1）。

Apache 運作良好，並且在本機上提供頁面正常，但虛擬伺服器只是逾時並顯示「DNS_PROBE_FINISHED_NXDOMAIN」。我對自己做錯了什麼感到困惑。

這是 PHP 7 版本的設定檔：-

<VirtualHost *:80>
ServerAdmin [email protected]
ServerName legacy.local
DocumentRoot /var/www/legacy.local
DirectoryIndex info.php

<Directory /var/www/legacy.local>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
</Directory>

<FilesMatch \.php$>
# From the Apache version 2.4.10 and above, use the SetHandler to run PHP as a fastCGI process server
SetHandler "proxy:unix:/run/php/php7.4-fpm.sock|fcgi://localhost"
</FilesMatch>

ErrorLog ${APACHE_LOG_DIR}/legacy.local_error.log
CustomLog ${APACHE_LOG_DIR}/legacy.local_access.log combined
</VirtualHost>

這是 PHP 8 版本的設定檔：-

<VirtualHost *:80>
ServerAdmin [email protected]
ServerName new.local
DocumentRoot /var/www/new.local
DirectoryIndex info.php

<Directory /var/www/new.local>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
</Directory>

<FilesMatch \.php$>
# From the Apache version 2.4.10 and above, use the SetHandler to run PHP as a fastCGI process server
SetHandler "proxy:unix:/run/php/php8.1-fpm.sock|fcgi://localhost"
</FilesMatch>

ErrorLog ${APACHE_LOG_DIR}/new.local_error.log
CustomLog ${APACHE_LOG_DIR}/new.local_access.log combined
</VirtualHost>

錯誤日誌顯示 PHP7 的 FPM 可用：-

[08-Dec-2022 13:20:36] NOTICE: fpm is running, pid 801
[08-Dec-2022 13:20:36] NOTICE: ready to handle connections
[08-Dec-2022 13:20:36] NOTICE: systemd monitor interval set to 10000ms

錯誤日誌顯示 PHP8 的 FPM 也可用：-

[08-Dec-2022 13:20:36] NOTICE: fpm is running, pid 821
[08-Dec-2022 13:20:36] NOTICE: ready to handle connections
[08-Dec-2022 13:20:36] NOTICE: systemd monitor interval set to 10000ms

我無法讓此配置正常工作，我重置了虛擬機器並使用了此處說明設定 PHP 的兩個版本。

總結：-

#Set up default Web Server with PHP 8.x
sudo apt-get install -y lamp-server^
#Add PHP 7.x
sudo add-apt-repository -y ppa:ondrej/php
sudo apt update -y
sudo apt install -y php7.4

要從 PHP 8.x 切換到 7.x：-

sudo a2dismod php8.1
sudo systemctl restart apache2
sudo systemctl status apache2
sudo a2enmod php7.4
sudo systemctl restart apache2
sudo systemctl status apache2

要從 PHP 7.x 切換到 8.x：-

sudo a2dismod php7.4
sudo systemctl restart apache2
sudo systemctl status apache2
sudo a2enmod php8.1
sudo systemctl restart apache2
sudo systemctl status apache2
