在 CentOS 7 上将 PHP 5.x 迁移到 PHP 7

在本文中，我们将学习如何将 PHP 5.x 升级和更新到 PHP 7，PHP 7 于 2015 年发布，其速度改进可与旧版本的 PHP 相媲美。

先决条件

假设我们已经在 CentOS7 上安装了 PHP 5.x，并且 Apache 应该启用了 mod_php 模块，我们需要 Sudo 权限或 root 用户。

启用 PHP 7 存储库

由于 PHP 7.x 在官方存储库中不可用，因此我们需要使用 IUS 社区项目存储库。

使用以下命令下载机器上的 IUS 存储库

# curl 'https://setup.ius.io/' -o setup-ius.sh
curl 'https://setup.ius.io/' -o setup-ius.sh
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 1913 100 1913 0 0 1554 0 0:00:01 0:00:01 --:--:-- 1555

使用以下命令将 IUS 存储库安装到本地机器

# bash setup-ius.sh
bash setup-ius.sh

升级 Apache 中的 mod_php 模块

在这里，我们将升级 Apachhe 模块 mod_php 的系统。首先，我们将使用以下命令删除旧的软件包。

# yum remove php-cli mod_php php-common

使用以下命令使用 IUS 存储库安装新的 PHP 7 模块。

# yum install php70-mysqlnd mod_php70u php70u-cli

最后，我们将重新启动 apache 并检查 apache 的状态

# systemctl restart httpd

检查 apache 服务状态

# systemctl status httpd

测试 PHP 版本

我们可以通过使用命令行模式来验证 PHP 版本，我们还可以创建一个 info.php 并检查 PHP 的版本

# php -v
PHP 7.0.8 (cli) (built: Jun 23 2016 11:34:57) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies

使用以下代码创建 info.php 文件并在 GUI 模式下检查信息。

# /var/www/html/info.php
<?php
Phpinfo();
?>

创建文件后，使用以下 URL 访问 Web 浏览器

http://IP_Address /info.php

在完成上述步骤的设置和配置后，我们现在可以将 CentOS 7 上的 PHP 5.x 更新到 PHP 7。截至目前，CentOS 7 的官方存储库尚未发布。我们还可以看到 PHP 7 已在服务器上升级。
