如何在Ubuntu Linux 14.04 LTS上安装PHP 7
在Ubuntu 14.04 LTS上安装和配置PHP 7的过程如下：
- 在Ubuntu Linux 14.04 LTS上启用ondrej/php
- 使用sudo apt-get update更新apt缓存
- 使用apt-cache search php7命令列出Ubuntu上的所有PHP 7软件包
- 通过运行
sudo apt-get install php7.0在Ubuntu上安装PHP 7软件包。 - 通过编辑nginx.conf文件，将Nginx配置为使用PHP 7
让我们详细查看所有命令。
为可共同安装的PHP 5.6 + 7.0配置PPA
执行以下命令：
$ sudo apt-get install -y language-pack-en-base $ sudo LC_ALL=en_US.UTF-8 add-apt-repository ppa:ondrej/php
或者
$ sudo add-apt-repository ppa:ondrej/php
更新包索引
要从其源重新同步包索引文件，请执行：
$ sudo apt-get update
输出示例：
