如何安装php7？

【问题标题】：How to install php7?如何安装php7？
【发布时间】：2015-12-04 18:25:31
【问题描述】：

由于php7已经发布，我想在我现在的机器上试用一下。

我尝试使用 this gist 从源代码构建它，但对我来说失败了（我已经在线程中发布了 error message）。

然而问题不一定是解决编译问题，而是更基本的问题：

如何安装php7？

我在 Ubuntu14.04 上，但我希望答案与操作系统无关。

【问题讨论】：

  • 不知道apt-get有没有更新，你试过apt-get update并尝试安装php7吗？无论如何，我很确定gist.github.com/tronsha/b471dd6d73dc8ebae242 中提出的解决方案仍然有效。
  • 在askubuntu上，有一个dupe和一个相关的question about future support
  • @Havenard 我试过了，对我来说失败了。你自己试过吗？ :)
  • 一些失败的测试。他们中的大多数人都预料到了。您的 PHP7 可能会正常工作。除了可能不是 curl 扩展。

标签： php installation


【解决方案1】：

在ubuntu 14.04系统中安装php7，请按照以下步骤进行：

sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php7.0

供mysql使用 

sudo apt-get install php7.0-mysql
sudo service apache2 restart

如果你想删除 php5，那么在安装 php7 之后，请按照以下步骤操作：

sudo apt-get update
sudo apt-get purge php5-common -y
sudo apt-get install php7.0 php7.0-fpm php7.0-mysql -y
sudo apt-get --purge autoremove -y

【讨论】：

  • 由于 Ondrey 是 Debian 中 PHP 树的官方所有者，因此 PPA 相当值得信赖。尽管如此，应该考虑到附加存储库可能会安装所有内容并可能带来安全风险。考虑到这一点，我也在使用它。
【解决方案2】：

我在https://jaimemontoya.com/learning-php-7/#20190807165248 分享了我在 Ubuntu 18.04.1 上安装 PHP 版本 7.0.33-8 的方式。我还发布了我的<?php phpinfo();?> 安装成功后返回的屏幕截图。请参阅下面我遵循的步骤：

更新 1：

按照您的要求，k0pernikus，从字面上看，它是如何在由 Antonio Lopez 撰写的 Learning PHP 7 的第 1 章中发布的，由 Packt Publishing 发布：

安装 PHP

在本节中唯一需要考虑的是删除任何以前的 您系统上的 PHP 版本。为此，您可以运行以下命令 命令：

$ sudo apt-get -y purge php.*

下一步是添加必要的存储库以获取 正确的 PHP 版本。添加和更新它们的命令是：

$ sudo apt-get install python-software-properties

$ sudo LC_ALL=en_US.UTF-8 add-apt-repository ppa:ondrej/php -y

$ sudo apt-get update

最后，我们需要安装 PHP 7 和 MySQL 驱动程序。 为此，只需执行以下三个命令：

$ sudo apt-get install php7.0 php7.0-fpm php7.0-mysql -y

$ sudo apt-get --purge autoremove -y

$ sudo apt-get --purge autoremove -y

$ sudo service php7.0-fpm start

【讨论】：

  • 您能否将输出减少为输入的实际命令？您有十个命令，其余的只是它们的输出（不必全部发布）。仅在真正有意义时才发布命令的输出。考虑到这一点，我看不出与kamlesh's 答案的区别，因为这似乎也在使用ondrej/php ppa 方法。
  • @k0pernikus 完成。请参阅我的更新 1。
