一、yum更换国内源
1、前往yum文件路径地址
[root@web1 ~]# cd /etc/yum.repos.d/
[root@web1 yum.repos.d]# ls
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo
CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo
[root@web1 yum.repos.d]#
2、下载相应的原包地址
[root@web1 yum.repos.d]# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

[root@web1 yum.repos.d]#
3、列出所有可安装的包
[root@web1 yum.repos.d]# yum list
4、如果一个163和base的源不够用的情况下，可以安装一个扩展源epel
yum install -y epel-release
yum list |grep epel
二、yum下载rpm包
1、下载包不安装
[root@web1 yum.repos.d]# yum install -y 包名 –downloadonly –downloaddir=路径
2、已经安装的包要重新安装
[root@web1 yum.repos.d]# yum reinstall -y 包名 –downloadonly –downloaddir=路径
****将需要的rpm包打包好以后再使用时便可直接调用了****
