在CentOS 7-8上安装PHP 8.0

原文：https://www.iplayio.cn/post/739811

在CentOS 8上安装PHP 8.0

我们将使用REMI存储库在CentOS 8 / CentOS 7 Linux系统上安装PHP 8。安装有两种选择

• 安装PHP 8.0作为主要的PHP版本
• 与其他PHP版本一起安装PHP 8.0

将PHP 8.0安装为默认版本

如果您希望安装并将PHP 8.0作为默认版本，请使用以下命令。这意味着用PHP 8.0提供的软件包替换发行版中的基本软件包。

CentOS 8：

sudo dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf -y install https://rpms.remirepo.net/enterprise/remi-release-8.rpm
sudo dnf -y install yum-utils
sudo dnf module reset php
sudo dnf module install php:remi-8.0 -y
sudo dnf install php -y
yum install php-fpm
systemctl enable php-fpm
yum install php-mysqlnd

yum install php-mbstring

安装compose:
php -r "copy('https://install.phpcomposer.com/installer', 'composer-setup.php');"

php composer-setup.php

php -r "unlink('composer-setup.php');"

上述 3 条命令的作用依次是：

1. 下载安装脚本 － composer-setup.php － 到当前目录。
2. 执行安装过程。
3. 删除安装脚本

全局安装：sudo mv composer.phar /usr/local/bin/composer


https://www.phpcomposer.com/

CentOS 7：

sudo yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm
sudo yum -y install yum-utils
sudo yum-config-manager --disable 'remi-php*'
sudo yum-config-manager --enable remi-php80
sudo yum -y install php php-{cli,fpm,mysqlnd,zip,devel,gd,mbstring,curl,xml,pear,bcmath,json}

要安装任何其他PHP软件包，请使用命令语法：

sudo yum install php-xxx

检查PHP版本：

$ php --version
PHP 8.0.0RC4 (cli) (built: Nov 10 2020 10:57:27) ( NTS gcc x86_64 )
Copyright (c) The PHP Group
Zend Engine v4.0.0-dev, Copyright (c) Zend Technologies

与其他PHP版本一起安装PHP 8.0

在CentOS 8上安装PHP 8.0：

sudo dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf -y install https://rpms.remirepo.net/enterprise/remi-release-8.rpm
sudo dnf -y install yum-utils
sudo dnf module reset php
sudo dnf install php80

通过按键盘上的y键接受安装：

配置nginx访问php-fpm

1,准备测试用的目录和代码:

[root@kubemaster web]# mkdir /data/web/phpweb
[root@kubemaster web]# mkdir /data/web/phpweb/html
[root@kubemaster web]# cd /data/web/phpweb/html
[root@kubemaster html]# vi info.php
[root@kubemaster html]# more info.php
<?php
phpinfo();
?>

 

2,配置nginx

   在nginx的配置文件中增加一个虚拟主机,使可以访问php

   demo如下：

      server {
        listen       8003;
        root   /data/web/phpweb/html;
 
        location ~ .php {
                fastcgi_pass   127.0.0.1:9000;
                fastcgi_index  index.php;
                fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
                include        fastcgi_params;
        }
    }

    然后重启nginx

 

  3，从浏览器访问php

访问:

http://127.0.0.1:8003/info.php

[root@vmcentos7 nginx]# yum install php80-unit-php
