最后我决定将 CentOS 5 迁移到 7，但我无法从 yum 或服务器内部获取 httpd 模块。
我读到我们不能盲目使用apache 2.2配置2.4，模块名称可能会被更改或删除。我如何知道它被改成了什么？
如何从 yum 获取模块？yum whatprovides mod_authz_default.so 没有返回任何包。
我不断地逐个注释，它会列出下一个。是的，/usr/lib64/httpd/modules 中有模块，但不是旧 httpd.conf 所需的模块。

答案1
apache 2.4看来这些模块已从mod_authn_default、mod_authz_default、mod_mem_cache中删除。参考 apache 升级文档
对于mod_ident.c其他模块，我从 GitHub 下载了源代码并进行了编译。
例子：
[root@myhost ~]# wget https://raw.githubusercontent.com/omnigroup/Apache/master/httpd/modules/metadata/mod_ident.c
[root@myhost ~]# apxs -a -i -c mod_ident.c
答案2
您可以在服务器 centos 7 上搜索 mod_cache_disk 而不是 mod_disk_cache。正如您在以下图片链接上看到的：https://prnt.sc/10jpipm
