2018/02/27 posted in  日常问题 日常折腾

Ubuntu上官方的源,比如 Ubuntu14.04 默认源中的是 PHP5.6.x、Ubuntu16.04 默认源中的是 PHP7.0.x,那么如果想在 Ubuntu16.04 上安装 PHP7.1,PHP7.2,应该怎么办呢?

答案是通过第三方的源来安装,ppa:ondrej/php 是一个比较知名的PHP源(目前维护php5.6,php7.0,php7.1,php7.2)。下面就用这个源来安装自己想要的PHP版本。

  1. 通过源安装PHP bash sudo add-apt-repository ppa:ondrej/php
    sudo apt-get update
    sudo apt-get upgrade
    sudo apt-get install php7.1 # for PHP 7.1
    sudo apt-get install php7.0 # for PHP 7.0
    sudo apt-get install php5.6 # for PHP 5.6
  2. 安装相关版本的PHP模块 bash sudo apt-cache search php7*
    ...
    php-all-dev - package depending on all supported PHP development packages
    php7.0 - server-side, HTML-embedded scripting language (metapackage)
    php7.0-cgi - server-side, HTML-embedded scripting language (CGI binary)
    php7.0-cli - ⌘-line interpreter for the PHP scripting language
    php7.0-common - documentation, examples and common module for PHP
    php7.0-curl - CURL module for PHP
    php7.0-dev - Files for PHP7.0 module development
    php7.0-gd - GD module for PHP
    php7.0-gmp - GMP module for PHP
    ...
    ...
    ...
    php7.1-xml - DOM, SimpleXML, WDDX, XML, and XSL module for PHP
    php7.1-xmlrpc - XMLRPC-EPI module for PHP
    php7.1-zip - Zip module for PHP
    php7.1-opcache - Zend OpCache module for PHP
    php7.1 - server-side, HTML-embedded scripting language (metapackage)
    php7.1-xsl - XSL module for PHP (dummy)
    ...
    ...
    php7.2-bcmath - Bcmath module for PHP
    php7.2-bz2 - bzip2 module for PHP
    php7.2-cgi - server-side, HTML-embedded scripting language (CGI binary)
    php7.2-cli - ⌘-line interpreter for the PHP scripting language
    php7.2-common - documentation, examples and common module for PHP
    php7.2-curl - CURL module for PHP
    php7.2-dba - DBA module for PHP
  3. 选择需要的模块,安装之 sh sudo apt-get install php7.2-curl php7.2-dev php7.2-gd php7.2-imap php7.2-intl php7.2-mbstring php7.2-mysql php7.2-xml php7.2-zip
  4. 切换PHP版本 sh sudo update-alternatives --config php
  5. 设置Apache与正确的PHP版本一起运行 sh sudo a2dismod php7.1 # unload the current version
    sudo a2enmod php5.6 # load the version you need
    sudo service apache2 restart # restart webserver to apply

到此结束,再也不用担心安装PHP,切换PHP版本这些事情啦。
