解决方案 ："1月11日ECS Linux系统安装源（yum/deb/apt等）服务暂停与升级"

这里就是重点来了，如何解决本次的软件源暂时无法使用的问题呢？ 那就是提前换一个可以使用的软件源。 

这里需要用到代码编辑器和SFTP软件，如果没有安装，建议参考：【云计算的1024种玩法】ECS和轻量应用服务器的远程控制入门 

RHEL、CentoS 

修改 /etc/yum.repos.d/ 目录下的文件，例如：CentOS-Base.repo 、epel.repo 等，这里以修改 CentOS 7 本身的软件源文件 CentOS-Base.repo 为例： 

将 CentOS-Base.repo 修改为 CentOS-Base.repo.old 

然后创建一个新的 CentOS-Base.repo 文件，写入清华源的内容： 

复制代码

# CentOS-Base.repo

#

# The mirror system uses the connecting IP address of the client and the

# update status of each mirror to pick mirrors that are updated to and

# geographically close to the client.  You should use this for CentOS updates

# unless you are manually picking other mirrors.

#

# If the mirrorlist= does not work for you, as a fall back you can try the

# remarked out baseurl= line instead.
