Centos配置yum本地源aliyun的EPEL源
1、本地yum源
[root@openstack ~]# mount /dev/sr0 /mnt/
[root@openstack ~]# echo "/dev/sr0/mnt iso9660 defaults 0 0" >> /etc/fstab
[root@openstack ~]# rm -rf/etc/yum.repos.d/*
[root@openstack ~]# cat >/etc/yum.repos.d/rhel6.repo <
> [rhel6-source]
> name=rhel6-source
> baseurl=file:///mnt
> enabled=1
> gpgcheck=0
> EOF
2、配置阿里云网络yum源
阿里云镜像源站点（http://mirrors.aliyun.com/）。
centos镜像参考：http://mirrors.aliyun.com/help/centos
CentOS
1、备份
mv /etc/yum.repos.d/CentOS-Base.repo/etc/yum.repos.d/CentOS-Base.repo.backup
2、下载新的CentOS-Base.repo 到/etc/yum.repos.d/
CentOS 5
wget -O /etc/yum.repos.d/CentOS-Base.repohttp://mirrors.aliyun.com/repo/Centos-5.repo
CentOS 6
wget -O /etc/yum.repos.d/CentOS-Base.repohttp://mirrors.aliyun.com/repo/Centos-6.repo
CentOS 7
wget -O /etc/yum.repos.d/CentOS-Base.repohttp://mirrors.aliyun.com/repo/Centos-7.repo
3、之后运行yum makecache生成缓存
RHEL系统配置：
[root@openstack ~]# yum clean all
[root@openstack ~]# yum list
[root@openstack ~]# wget -O/etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
[root@openstack ~]# sed -i 's/$releasever/6.7/g'/etc/yum.repos.d/CentOS-Base.repo [root@openstack ~]# yum clean all
[root@openstack ~]# yum list
3、配置阿里云epel源：
配置参考：http://mirrors.aliyun.com/help/epel
Epel
1、备份(如有配置其他epel源)
mv /etc/yum.repos.d/epel.repo/etc/yum.repos.d/epel.repo.backup
mv /etc/yum.repos.d/epel-testing.repo/etc/yum.repos.d/epel-testing.repo.backup
2、下载新repo 到/etc/yum.repos.d/
epel(RHEL 7)
wget-O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
epel(RHEL 6)
wget-O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
epel(RHEL 5)
wget-O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-5.repo
