ubuntu (14.04) 에서 php 업데이트 하기

도쿠위키를 설치하려다가 다음과 같은 에러가 나와서 설치가 중단되었다.  

The installer found some problems, indicated below. You can not continue until you have fixed them.

Your PHP version 5.5.9-1ubuntu4.26 is lower than the needed 5.6.0. You need to upgrade your PHP install.

도쿠위키를 설치하기 위해서는 PHP 버전이 적어도 5.6 은 되어야 한다고 해서 

중간에 아래와 같이 PHP 업데이트를 진행하였다. 

PPA(Personal Package Archive) 라는 개인 패키지 아카이브를 사용해서 (블로그 참조) 

업데이트를 진행하였다. 

유분투에서 PHP 7.0 설치를 지원하는 PPA 를 일단 추가해보자. 

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

Co-installable PHP versions: PHP 5.6, PHP 7.x and most requested extensions are                                                                                              included.

Debian oldstable and stable packages are provided as well: https://deb.sury.org/                                                                                             #debian-dpa
