yum源文件

一 简介

1、安装过程中，rpm包依赖性太强。

2、如果所有的rpm包都是手工安装，则rpm包使用难度较大。

3、yum在线安装，它的好处是：将所有软件包放到官方服务器上，当进行yum在线安装时，可以自动解决依赖性问题。

4、redhat的yum在线安装需要付费，但centos不需要。

[root@localhost yum.repos.d]# cat CentOS7-Base-163.repo

# 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.
