PHP 8.1与CentOS 7.9的更新问题

Question

我正在尝试更新一个生产web服务器(在linode)从php 7.1到8.1，按照配置向导的说明，但似乎有一个依赖树错误，我犹豫使用--skip-broken以防它打破我的web服务器。这是最好的办法吗?如果更新后无法解决依赖关系，我可以轻松地恢复更新吗?我应该更新到最近的7吗?先用X版本?以下是yum update的输出:

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

Answer 1

Error: Package: php-pecl-apcu-bc-1.0.5-1.el7.remi.7.1.x86_64 (@remi-php71)
Requires: php(api) = 20160303-64

apcu_bc提供了与PHP 7的旧APC扩展的兼容性。

已弃用，PHP 8不再支持

所以你必须在升级之前删除它，如果你真的需要它，你不能升级，必须在升级之前修复使用它的应用程序。

Error: Package: php-gd-8.1.6-1.el7.remi.x86_64 (remi-php81)
Requires: libgd.so.103()(64bit)

缺失的依赖项在remi-safe在正确的安装中默认启用的存储库，按照向导说明

当然，由于这是一次重大升级，您必须确保所有应用程序都为这个新版本做好准备。
