我在 Amazon Linux 2 EC2 实例上安装了一个 WordPress 应用程序。当前安装的 PHP 版本是 7.4。我想将此版本更新到 8.0
我在 EC2 终端中执行了以下命令来升级 PHP ：
$ amazon-linux-extras | grep php
42 php7.4=latest enabled [ =stable ]
_ php8.0 available [ =stable ]$ amazon-linux-extras disable php7.4
....
....
42 php7.4 available [ =stable ]
.....
50 selinux-ng available [ =stable ]
51 php8.0 available [ =stable ]
.....
61 dnsmasq2.85 available [ =stable ]
* Extra topic has reached end of support.$ amazon-linux-extras | grep php
42 php7.4 available [ =stable ]
51 php8.0 available [ =stable ]$ amazon-linux-extras enable php8.0
....
42 _ php7.4 available [ =stable ]
....
51 php8.0=latest enabled [ =stable ]
.....
Now you can install:
# yum clean metadata
# yum install php-cli php-pdo php-fpm php-mysqlnd$ yum clean metadata

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest从输出可以看出上述安装失败。我也用 --skip-broken 尝试了上述命令。但是输出是一样的。
从输出中，我认为问题出在 php-json 包上。所以我试图删除 php-json 包：
$ yum -y remove php-json-7.4.28-1.amzn2.x86_64
Removed:
php-json.x86_64 0:7.4.28-1.amzn2
Dependency Removed:
php-cli.x86_64 0:7.4.28-1.amzn2 php-common.x86_64 0:7.4.28-1.amzn2 php-fpm.x86_64 0:7.4.28-1.amzn2
php-gd.x86_64 0:7.4.28-1.amzn2 php-mbstring.x86_64 0:7.4.28-1.amzn2 php-mysqlnd.x86_64 0:7.4.28-1.amzn2

Complete!我再次尝试安装相同的软件包，如下所示：
$ yum install php-cli php-pdo php-fpm php-mysqlnd
.....
Installed:
php.x86_64 0:8.0.16-1.amzn2
Dependency Installed:

$ systemctl restart nginx
$ systemctl restart php-fpm.service现在我尝试访问该站点，浏览器显示 HTTP 502 错误。我在哪里犯了错误？
作为参考，我使用以下链接进行升级：

我有同样的问题，我的实例只是一个 LAMP 登台服务器，并不那么重要。
所以，我删除了 php-json sudo yum remove php-json 然后运行了 php 的安装
sudo yum install php php-{pear,cgi,common,curl,mbstring,gd,mysqlnd,gettext,bcmath,json,xml,fpm,intl,zip}
这一切似乎都奏效了，我的应用程序仍然有效。

php-json is available in Amazon Linux Extra topic "php7.4"
To use, run
# sudo amazon-linux-extras install php7.4希望能帮助到你。
