his guide is very similar to our other guide on installing PHP 7 since we’re using the same method although this time, as the title suggests we’ll be using the latest stable version of PHP instead, 7.1.

Update VestaCP to PHP 7.1 on CentOS 7

sudo yum update
php -v
sudo yum install yum-utils
sudo yum-config-manager --enable remi-php71
sudo yum update
After the process has finished your server will now have PHP 7.1 installed, we need to restart our web server for it to take effect however.

If you have Apache and NGINX installed, or just Apache installed run

sudo service httpd restart
sudo service php-fpm restart && sudo service nginx restart
php -v

This isn’t required but if you would like to keep your system clean then we can now disable the older versions of PHP from our system. To do this run the following

sudo yum-config-manager --disable remi-php56
sudo yum-config-manager --disable remi-php55
sudo yum-config-manager --disable remi-php56-debuginfo
sudo yum-config-manager --disable remi-php55-debuginfo
sudo yum clean all
sudo yum update
