Error 500 when upload the site files in centos 7 apache
I am newbie with Linux systems. I follow the tutorial https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-on-centos-7.
And it is all ok, but I can't upload my website files via SFTP, so I change the permission of the folder /var/www/html as follow:
sudo groupadd developer
sudo usermod -a -G developer admin
sudo chgrp -R developer /var/www/html/
sudo chmod -R 2775 /var/www/html/
So I was able to upload the files of the site, but when I trie to access return error 500, I tried to ping the server Ip and domain in windows cmd and it don't reply.
What I am doing wrong?
in the httpd log show this:
