更换CentOS7的yum源为阿里云
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.repo http://mirrors.aliyun.com/repo/Centos-5.repo
CentOS 6
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
CentOS 7
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
3、之后运行 yum clean all, yum makecache 生成缓存

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
ansible 分发其他机器
ansible hadoop -m shell -a "mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak" ansible hadoop -m shell -a "mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.bak" ansible hadoop -m copy -a "src=/etc/yum.repos.d/Centos-7.repo dest=/etc/yum.repos.d/Centos-7.repo" ansible hadoop -m copy -a "src=/etc/yum.repos.d/epel-7.repo dest=/etc/yum.repos.d/epel-7.repo" ansible hadoop -m shell -a "yum clean all && yum makecache"
