First you need to find the location of PHP.ini. You will need to have root access to your server before you can perform the following steps
Type this command in the shell:
php --ini |
It should output this text:
Configuration File (php.ini) Path: /usr/local/lib Loaded Configuration File: /usr/local/lib/php.ini |
Enable Exec() in PHP.ini
Open the PHP.ini file and remove “exec” on “disable_functions”:
disable_functions=show_source, system, shell_exec, exec |
So it will become like this:
disable_functions=show_source, system, shell_exec |
Then restart PHP service, use one of these commands:
/etc/init.d/php-fpm restart /etc/init.d/php5-fpm restart /etc/init.d/php7.0-fpm restart |
Disable Exec() in PHP.ini
Open the PHP.ini file and add “exec” on “disable_functions”:
disable_functions=show_source, system, shell_exec |
So it will become like this:
disable_functions=show_source, system, shell_exec, exec |
Then restart PHP service, use one of these commands:
/etc/init.d/php-fpm restart /etc/init.d/php5-fpm restart /etc/init.d/php7.0-fpm restart |
