Stuck installing - Internal Server Error

šŸš§ Installation
1

Gents

First time installing, and quite stuck. I used the approach here:
https://docs.nextcloud.com/server/latest/admin_manual/installation/example_centos.html

After completing instructions, I end with my server just showing

ā€˜Internal Ser ver Error
The server encountered an internalā€¦ā€™

I cannot find anything strange in any logs. The nextcloud.log is not updated. The httpd log just shows:

AH00558: httpd: Could not reliably determine the serverā€™s fully qualified domain name, using localhost.localdomain. Set the ā€˜ServerNameā€™ directive globally to suppress this message

Nothing very helpful there.

I have restarted httpd several times, no change. I have disable SELinux AND the firewall. No change.

I have logged into the DB (pgsql), and see that the tables have been created, telling me that the DB-config is ok.

Any other tips or trickes for debugging?

I take it youā€™re getting that error when trying to access the web interface to access the installation wizard for the very first time?

As long as you do not have a proxy involved, that internal server error (HTTP 500) must be getting logged both by httpd at a minimum, and Nextcloud too unless itā€™s a httpd only problem (well, unless logging is somehow been turned off or permissions are wrong).

The approach you took should yield a nextcloud.log in /var/www/html/nextcloud/data. When you say itā€™s not updatedā€¦ did it get created (automatically not by you)? And, if so, is there anything in it at all? Iā€™d check permissions of all intermediate parent folders (for example if data got created after the chown -R step accidentally).

For httpd, do you see the connection come in (i.e. if you tail -f /var/log/httpd/accesss_log) when you try to hit the URL?

Yes, trying to reach /nextcloud on the machine where it is installed (from another machine on network).

There is a nextcloud.log file in /var/www/html/nextcloud/data, but the last entry there is from the time when the installation started. I.e. nothing new written since then.

The /var/www folder is owned by root, while nextcloud (and below it) is owned by apache:apache. Permissions look sound, e.g.
drwxr-xr-x. 4 apache apache 118 Nov 2 22:37 data
-rw-r-----. 1 apache apache 6007 Nov 2 22:03 /var/www/nextcloud/data/nextcloud.log

The access_log file is written to, when I try to connect:
[15/Nov/2023:19:10:39 +0100] ā€œGET /nextcloud/ HTTP/1.1ā€ 500 292 ā€œ-ā€ ā€œMozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/119.0.0.0 Safari/537.36ā€

I tried removing the nextcloud.conf file from apache and ran <?php phpinfo(); ?> in an index.html file, and got the standard php info page. Telling me that the web-server is working on its own. I previously ran pgAdmin4 from the same machine, but have excluded that from the current config.

What to do?
