Why Upgrade?

• Faster!
• New features!
• <5.5 is unsupported

Upgrading - Ubuntu

• cat /etc/*release*

  • 15.04? sudo do-release-upgrade

• dpkg --get-selections '*php*'

• sudo add-apt-repository ppa:ondrej/php

• sudo apt update

Upgrading - Ubuntu

• sudo apt purge php5-common php5-dev

• sudo apt-get autoremove

• sudo apt install php7.0-mysqli php7.0-mysqlnd

Upgrading - Ubuntu

• Configs moved:
  • /etc/php5/ vs /etc/php/7.0/
  • Good idea to keep your customizations separate:
    /etc/php/7.0/apache2/conf.d/99-yourapp.ini

Upgrading - Ubuntu

• Apache:

  • sudo apt install libapache2-mod-php7.0

  • sudo a2enmod php7.0

Upgrading - CentOS

• Webtatic repos contain PHP versions 5.4 and above
• Need epel first

  • sudo rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

  • sudo rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

Upgrading - CentOS

• sudo yum remove php56w-common php56-dev

• sudo yum install php70w-opcache

Upgrading - CentOS

• Apache:

  • sudo yum remove mod_php56w

  • sudo yum install mod_php70w

Upgrading - CentOS

• Config stays in the same location:

  • /etc/php.ini

  • /etc/php.d/
