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 <<EOF

> [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
