阿里云内网更新源

|Font Size: | No Comments | Previous

  购买阿里云的ECS服务器时,公网带宽选择0M带宽则不分配公网IP,这就意味着这台ECS服务器无法访问外网,也就无法使用yum或者apt-get等命令安装或者更新软件了。

  没想到阿里云早就提供了自己内网更新源。使用内网yum源不占用公网流量,有公网IP的服务器也可以使用。 下面是阿里云的内网更新源使用方法:

   打开 http://mirrors.aliyun.com/ ,点击对应自己系统后面的 Help 链接,按照提示修改或者下载更新源,不同的是要将源的域名从 mirrors.aliyun.com 改为 mirrors.aliyuncs.com 。

   CentOS6为例:

# 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.

#
