PHP extensions

I’m not sure what you mean. Please explain your hosting environment.

I mean for setting up VPS running Centos 7.

You will need mod_rewrite (which is installed by default when you install httpd) and mod_php. However, I strongly recommend you use php_fpm as it provides a better level of security and control.

Also, use the ius repo to get PHP 7

A sample of my config files are here:

Thanks for your assist! I am using PHP 7.1 and I ask for the extensions like gd, mysql etc.

Another question that popped is this the right setting of httpd.conf?

<Directory /var/www/html>
AllowOverride All
</Directory>

because I still get error 404 when I update permalink settings. The .htaccess file is setup properly with write privileges.

Assuming your wordpress install is in /var/www/html, you’ll need that either in .htaccess or in your httpd config file for that virtual host.

install gd, php-gd, ImageMagick, and mariadb

Thanks
