yum安装本地rpm软件方案详解 https://www.jb51.net/article/132305.htm

createrepo CentOS-Media.repo 本地软件源 --downloadonly --downloaddir 只下载不安装

# 关闭网络软件源
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo_bk

# 开启本地软件源
编辑 CentOS-Media.repo
vim /etc/yum.repos.d/CentOS-Media.repo
通过 baseurl 指定本地 rpm 包所在的目录。
baseurl=file:////home/user/rpms/
将这个源设置为开启
enabled=1
这样就可以使yum采用本地源安装软件。
