PHP Xdebug installation on Fedora/CentOS x64

First, install xdebug package on system:

$ sudo yum install php-pecl-xdebug.x86_64

Or with DNF:

$ sudo dnf install php-xdebug

Open and edit the php.ini file:

$ sudo vim /etc/php.ini

Add the following 2 lines to the end of the file:

zend_extension="/usr/lib64/php/modules/xdebug.so"`
xdebug.remote_enable = 1

The value for zend_extension will the directory in which xdebug.so is installed in. To check the directory, run:

$ updatedb && locate xdebug.so

Finally, if your have an Nginx server, we should restart the PHP processor php-fpm:

$ sudo systemctl restart php-fpm

Or if you have a Apache server, we should restart the httpd server:

$ sudo systemctl restart httpd
