在学习centos8的时候，遇到安装软件默认是无法指定安装版本的，所以就写一篇教程
1.搜索软件仓库中某个特定软件的所有可安装版本和相关插件等信息（下面拿NGINX软件举例子）
dnf --showduplicates search nginx
2.查看软件仓库中某个特定软件的所有可安装版本（下面拿NGINX软件举例子）
dnf --showduplicates list nginx
3.安装特定软件版本时，需要输入软件的精确名称与版本号才可以
[root@localhost ~]# yum --showduplicates search nginx 上次元数据过期检查：0:35:15 前，执行于 2023年01月09日 星期一 15时43分09秒。

4.比如需要安装 nginx-1:1.20.2-1.el8.ngx.x86_64 软件，如下：
dnf install -y nginx-1:1.20.2-1.el8.ngx.x86_64
5.查看软件安装的详细信息
[root@localhost ~]# dnf info nginx

6.如果你搜索结果只有一个版本或者没有结果，说明你的软件仓库可能没有此软件的更多版本或者干脆没有此软件，此时就需要额外添加DNF源进去。
7.创建NGINX源文件
vi /etc/yum.repos.d/nginx.repo
8.把下面内容添加进去
[nginx-stable] name=nginx stable repo baseurl=http://nginx.org/packages/centos/$releasever/$basearch/ gpgcheck=1 enabled=1 gpgkey=https://nginx.org/keys/nginx_signing.key module_hotfixes=true [nginx-mainline] name=nginx mainline repo baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/ gpgcheck=1 enabled=0 gpgkey=https://nginx.org/keys/nginx_signing.key module_hotfixes=true
9.清理并重新生成dnf缓存
#清理dnf缓存 dnf clean all #重新生成dnf缓存 dnf makecache
10.如果下载速度偏慢，是因为NGINX服务器在海外的原因。
