CentOS 7 最小安装功能扩展-白红宇

首先，我们使用centos一般使用yum安装文件，其条件：

1：必须能接入互联网；（）

2：有yum功能插件。（可手动下载安装）

需要安装“net-tools”，执行下命令，会报错：

扩展功能：

网络：net-tools

编辑器[option]：vim

编译器：c/c++: gcc /gcc-c++

[root@localhost ~]#  yum install -y net-tools

One of the configured repositories failed (未知), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: .... Cannot find a valid baseurl for repo: base/7/x86_64

解决：

在域名服务器配置中，添加一个8.8.8.8（或者其他），就解决了:# vi /etc/resolv.conf  add：#Generated by NetworkManager  nameserver 8.8.8.8

之后，yum使用正常。

[root@localhost ~]#  yum -y  install vim*

vim安装问题失败：
