Apache Config Issue/Conflict(?)

Question

Raspian 10 (Buster)
Apache 2.4.38
lighttpd 1.4.53

I previously installed lighttpd and it was/is running w/out issue. Today I installed apache so I can run ownCloud. I went through the installation process without issue for apache, owncloud, and the owncloud dependencies. After the initial install I was able to access the owncloud admin setup page at the via 192.168.1.10/owncloud (/var/www/html/owncloud) but I ran into PHP errors. I realized that lighttpd was using port 80 on 127.0.0.1 loopback and was preventing apache from loading properly. So I switched lighttpd to port 8080. After restarting the service it happily went about it's business. I restarted apache at which point I am not able to access any files via apache on 80.

Not Found. The requested URL was not found on this server. Apache/2.4.38 (Raspbian) Server at 192.168.1.10 Port 80

I run checks on apache to make sure it is configured correctly.

systemctl status apache2 which comes up good and apache2ctl -t which returns OK. so everything looks good. So I change apache log reporting to debug and look at the log files:

Access log:

192.168.1.20 - - [05/May/2020:18:38:35 -0900] "GET /index.php HTTP/1.1" 404 496 "http://192.168.1.10/"

Error log:

[Tue May 05 18:38:35.852298 2020] [core:info] [pid 703:tid 2882475040] [client 192.168.1.20:55977] AH00128: File does not exist: /var/www/owncloud/index.php, referer: http://192.168.1.10/

Still nothing obvious. I rebooted. It doesn't load I'm alive! at the doc root either. I've looked through the all the apache config files but I can't see anything and I've read through numerous searches. I know this is a simple issue but can't figure it out.

I know I am overlooking something basc but for the life of me I can't spot it. Any help appreciated!

Here is what my vhost file looks like:

<VirtualHost *:80>

        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        <Directory /var/www/html>
              Options Indexes FollowSymLinks
              AllowOverride All
              Order allow,deny
              Require all granted
        </Directory>

</VirtualHost>

I solved this. Not sure what the issue was but it was something very basic, either in the config files or with ownership/permissions. I solved it by installing another apache instance on a separate machine and then copying across the config and index files. I have no idea what of the root cause but... well it's done now.

Here what I did:

   21  wget "https://download.owncloud.org/community/owncloud-10.4.1.tar.bz2"
   22  tar -xvjf owncloud-10.4.1.tar.bz2
   23  rm /var/www/html/index.html
   24  mv owncloud/* /var/www/html
   25  apt search php apache2
   26  apt install libapache2-mod-php
   27  service apache2  restart
   28  apt install php7.3-zip php7.3-xml php7.3-intl php7.3-zip php7.3-gd php7.3-curl php7.3-mysql php7.3-mbstring
   29  service apache2  restart

With default settings apache2 started owncloud right away. I guess, you better: rm -r /var/www/html/*, apt purge apache2, rm -r /etc/apache2, apt install php7.3-zip php7.3-xml php7.3-intl php7.3-zip php7.3-gd php7.3-curl php7.3-mysql php7.3-mbstring libapache2-mod-php apache2. Maybe you need to do the same with php.
