IDK why it's returning so much errs i literally use the same project on my windows xampp
I would suggest to check the PHP version and use a compatible one. You can use command php --version on linux. I see that you are trying to run PHPmyadmin, its advised to go through its version notes and check which PHP versions it supports.
I Fixed the problem
despite my project's problem which a false addressing in files was causing it
the PhpMyAdmin was not Responding because I hadn't installed an E called mbstrings as you can see in errors there is an undefined function mbstrops() which actually needs the mbstring Extension to run correctly i just installed the package which was compatible with my php version (8.0.1) and i got everything working correctly
in order to see how to install mbstrings Extesion see this :

Reload apache within a python script on linux

Hi I am trying to create a python file that reloads apache2 the code of this file is:
import os
os.system("service apache2 reload")
When I use the command in the terminal everything works fine but when I run the python script I got this error:
Job for apache2.service failed.
See "systemctl status apache2.service" and "journalctl -xe" for details.
so I checked the journalctl and got this:
nov 29 13:50:19 gerrietech apachectl[37415]: Action 'graceful' failed.
nov 29 13:50:19 gerrietech apachectl[37415]: The Apache error log may have more information.
end this comes out of the error log:
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 192.168.50.183. Set the 'ServerName' directive globally to suppress this message

How do i fix this?
After i used /etc/init.d/apache2 reload instead of service apache2 restarti dont get any errors and the script does what it is supposed to do

Ubuntu 18.04 Apache automatically crashing frequently for NodeJS Angular based application in AWS EC2 and stopping

I am using Ubuntu 18.04 on AWS EC2 instance free tier, running websites on Apache server, NodeJS with PostgreSQL database. All deployments are done perfectly and web-apps works fine without any exception or error details.
However I am facing an annoying issue: this instance is stopping frequently without any exception or error logs. After rebooting instance everything starts working fine but after some time it automatically stops either in few hrs. on same day when rebooted instance or in 1-2 days after that.
Below are some Apache logs (var/log/apache2) I tried to analysed but couldn't found out what is causing this exactly:[there is error log is looks related to this:

I had seen this type of issue before and it was DNS issue.
after lots of searches, I found out that the DNS of my domain was not registered correctly.

where could be the problem?
On Linux side you are using mod_auth_kerb which supports Kerberos authentication but your client sends NTLMSSP. This is unsupported.
If you want to have NTLMSSP working, you'd better to use mod_auth_gssapi and GSSAPI NTLMSSP modules from https://github.com/simo5/mod_auth_gssapi and https://fedorahosted.org/gss-ntlmssp/

500 internal server error on laravel?

I made a project in laravel and when I migrated to a live server it gives me 500 internal error.
This is the first time I try to install laravel.
The problem occurs when I run rm -rf public_html AND ln -s laravel/public/ public_html

Change the permissions of your app/storage folder to 755 if that doesn't works change it to 777. If you are running nginx on the server check /etc/nginx/nginx.conf file and check the first which states the user running nginx and then
chown -R www-data:www-data /your/document/root/public_html/
change www-data by the user name you found in config file you can also validate it by running ps on terminal
