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 this line zend_extension="/usr/lib64/php/modules/xdebug.so"
to the file's end.
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
