Install PHP 7.1 on a Ubuntu Xenial with VestaCP

[floown]

Hello,

I have installed a lamp with VestaCP on a Ubuntu Xenial. Now, I should update the php version (PHP 7.0.22-0ubuntu0.16.04.1) to the last PHP 7.1 because Drupal 8.4 need it.

Is there a tutorial to do this properly with VestaCP installed for Xenial?

Thanks for your help

You should have been able to get this straight with some search. Pretty common thing to do.

Code: Select all

sudo apt-get install -y python-software-properties
sudo add-apt-repository -y ppa:ondrej/php
sudo apt-get update -y

Then you can list all of the available PHP 7.1-related packages for review:

Code: Select all

apt-cache pkgnames | grep php7.1

if you don't want PHP 7.0 at all, you can remove it

Code: Select all

sudo apt-get remove php7.0

Code: Select all

sudo apt-get install php7.1
sudo apt install libapache2-mod-php7.1

IMPORTANT

Code: Select all

a2dismod php7.0 && a2enmod php7.1
systemctl restart apache2

You may also need these pkgs updated to 7.1

Code: Select all

sudo apt install -y php7.1-xml php7.1-zip php7.1-mysql php7.1-curl php7.1-mbstring php7.1-json php7.1-gd php7.1-intl php7.1-mcrypt php7.1-xsl php7.1-soap php7.1-common php7.1-readline php7.1-cli php7.1-opcache php7.1-iconv php7.1-sqlite3

Oh ok, so I can take any tutorial available on the internet to migrate a Xenial installation to php 7.1 without worrying about VestaCP. VestaCP does not require reconfiguration, is that it?

[mehargags]

Yes... Kind of!!
VestaCP mostly alters/manipulates system configs though, but for Nginx/Apache it "creates" split configs in a special way. however, they are in the same standard format.

Just do your PHP7.1 install, post any problems that you may face.

sudo apt-get remove php7.0

I have just remove php7.0 like you say and do a sudo apt-get purge php7.0-common

It seems working well.

Thanks again
