Fresh ownCloud 10.8 install ends into internal server error

Server
,
1

Hello,

I am an ownCloud user since a while (this project is really awesome!), and I decided recently to close my old Debian 8/ownCloud 9 VM to create a new CentOS 8 one with fresh install of latest ownCloud.

Unfortunately after submitting the information at the initial ownCloud setup page, I will end up into the internal server error template page…
I also configured SELinux permissions to make sure it’s not causing trouble, tried both nginx and apache servers, without luck. The database gets correctly populated. Webserver log is not talkative.
I tried to provide as much information as possible below. Don’t hesitate to ask anything further if needed. Oh and don’t mind about the 4443 port and www2 directory, it was just set like this because apache and nginx are sitting together inside the VM (I still can “move” owncloud to nginx instance if needed).

Thanks in advance for your help and advices!

Have a great day.
FabZ

It seems ownCloud is having problems to store new PHP sessions.

Double-check where the sessions are stored and ensure apache / nginx has enough permissions to write there. This isn’t directly related with ownCloud but PHP.
You might also want to try with debian / ubuntu since they usually give less trouble.

Hello,

You are perfectly right, thank you so much!
The permissions in /var/opt/remi/php74/lib/php were set to root:apache …
root@MFS-KERWEN(10:03:17):[/home/FabZ_FR]#: ls /var/opt/remi/php74/lib/php -l
total 0
drwxrwx—. 2 root apache 6 16 nov. 17:40 opcache
drwxr-xr-x. 2 root root 107 30 nov. 10:13 peclxml
drwxrwx—. 2 root apache 6 16 nov. 17:40 session
drwxrwx—. 2 root apache 6 16 nov. 17:40 wsdlcache

After giving the ownership to nginx and restarting php74-php-fpm service, it’s now working flawlessly.

Thanks again and have a great day!
