如何在CentOS 8 / RHEL 8上安装PHP 8.0
广告
PHP是嵌入在HTML中的一种开源编程语言。 它主要用于创建动态网站，例如博客，电子商务网站等。RasmusLerdorf于1994年创建了它。
CentOS 8 / RHEL 8默认带有PHP v7.2。
在这篇文章中，我们将看到如何在CentOS 8 / RHEL 8上安装PHP 8.0。
添加Remi存储库
Remi，一个第三方存储库，为Red Hat Enterprise Linux提供了多个PHP版本（8.0 / 7.4 / 7.3 / 7.2）。
Remi系统信息库要求在系统上启用EPEL系统信息库。 因此，在系统上安装最新的EPEL存储库自动配置rpm，以启用EPEL存储库。
dnf install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
然后，使用以下命令安装Remi存储库自动配置软件包。
dnf install -y https://rpms.remirepo.net/enterprise/remi-release-8.rpm
输出：

安装Remi存储库rpm后，列出可用的PHP模块流。
dnf module list php
您应该看到以下输出。
CentOS-8 - AppStream Name Stream Profiles Summary php 7.2 [d] common [d], devel, minimal PHP scripting language php 7.3 common [d], devel, minimal PHP scripting language Remi's Modular repository for Enterprise Linux 8 - x86_64 Name Stream Profiles Summary php remi-7.2 common [d], devel, minimal PHP scripting language php remi-7.3 common [d], devel, minimal PHP scripting language php remi-7.4 common [d], devel, minimal PHP scripting language php remi-8.0 common [d], devel, minimal PHP scripting language Hint: [d]efault, [e]nabled, [x]disabled, [i]nstalled
在CentOS 8 / RHEL 8上安装PHP 8.0
启用php：remi-8.0模块以安装PHP 8.0。
dnf module enable php:remi-8.0 -y
输出：
Dependencies resolved. =================================================================================================================== Package Arch Version Repository Size =================================================================================================================== Enabling module streams: php remi-8.0 Transaction Summary =================================================================================================================== Complete! Switching module streams does not alter installed packages (see 'module enable' in dnf(8) for details)
使用dnf命令在CentOS 8 / RHEL 8上安装PHP 8.0。
dnf install -y php php-cli php-common
在CentOS 8 / RHEL 8上安装PHP 7.x
如本文所示，启用php：remi-7.x模块以在系统上安装PHP7.x。
安装PHP-FPM
如果要在RHEL 8上设置LEMP堆栈，则可能要安装php-fpm。
dnf install -y php-fpm
安装PHP扩展
PHP扩展是已编译的库，可为您的代码提供特定的支持。

要在代码上提供MySQL支持，可以安装php-mysqlnd软件包。
dnf install -y php-mysqlnd
现在，以下命令将列出已安装的MySQL扩展。
php -m | grep -i mysql
输出：
mysqli mysqlnd pdo_mysql
结论
就这样。 我希望您已经学会了如何在CentOS 8 / RHEL 8上安装PHP 8.0。请在评论部分中分享您的反馈。
