php - Install redis extension for php 7.4 on Debian server

问题描述

I'd like to install php7.4-redis on my debian server. My php is 7.4 version.

When I run the "sudo apt install php7.4-redis" command , it shows 404 not found so I can't finish my setting.

However , I found the page has other version : php7.4-redis version

I've run command "sudo apt-get update" to update the repository but why am I still getting the 404 error?

解决方案

尝试运行apt update，然后它应该可以工作。

APT 在运行时会在本地缓存每个存储库中可用的包apt update。如果你安装一个包，apt 将使用这个缓存。但是，当服务器上的软件包更新并且旧版本被删除时，apt 将尝试检索不再存在的文件。此日志输出表明了这一点：

404  Not Found
E: Failed to fetch https://packages.sury.org/php/pool/main/p/php-redis/php7.4-redis_5.3.2+4.3.0-7+0~20210228.34+debian9~1.gbp893bd4_amd64.deb  404  Not Found

如果您查看repos 列表，您的版本5.3.2+4.3.0-7+0~20210228.34+debian9~1.gbp893bd4明显丢失。因此，经过一个apt updateapt 后就会知道从哪里加载包。

编辑：您的系统上有一个来自 php sury 的旧签名密钥，因此无法更新 repo 并且无法获取要下载的当前版本。这是一个已知问题，我在所有主机上都遇到过。

在链接的 GitHub 线程中，建议的修复是简单地运行这些命令（由 stefanux 发布）：

$ apt-key del 95BD4743 # If this throws an error about the key not being present, it's fine
$ wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
$ apt-get update

现在你应该可以安装 redis 包了。
