（網(wǎng)卡配置資料）

原因：

????????網(wǎng)絡(luò)問題

報(bào)錯(cuò)詳情：

 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:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Run the command with the repository temporarily disabled
            yum --disablerepo=<repoid> ...

     4. Disable the repository permanently, so yum won't use it by default. Yum
        will then just ignore the repository until you permanently enable it
        again or use --enablerepo for temporary usage:

            yum-config-manager --disable <repoid>
        or
            subscription-manager repos --disable=<repoid>

     5. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true

Cannot find a valid baseurl for repo: base/7/x86_64

解決步驟：

1、修改虛擬機(jī)的網(wǎng)絡(luò)連接模式為 NAT模式

2、右擊桌面，打開終端

①首先查看網(wǎng)關(guān)配置文件名：

輸入

ifconfig

②配置網(wǎng)卡信息：

vi /etc/sysconfig/network-scripts/ifcfg-ens32

?兩種方法：

點(diǎn)擊鍵盤 I ，開始輸入

第一種：自動(dòng)配置

①

1、BOOTPROTO=dhcp（自動(dòng)獲取ip）

2、ONBOOT=yes（設(shè)置開機(jī)自啟動(dòng)）

②

ESC--》:wq

在終端輸入

?service network restart

重啟網(wǎng)絡(luò)服務(wù)?

ping www.baidu.com

查看網(wǎng)絡(luò)是否通，如圖

第二種：手動(dòng)配置（之前配置有用的，但重新做了一遍，又不行了。把大體思路記錄下吧）

①主機(jī)cmd,輸入：

ipconfig

?找到所用的網(wǎng)的IP

BOOTPROTO= static (需手動(dòng)配置）?

?②

ESC--》:wq

在終端輸入

?service network restart

重啟網(wǎng)絡(luò)服務(wù)?

ping www.baidu.com

查看網(wǎng)絡(luò)是否通，如圖

驗(yàn)證

安裝gcc

yum -y install gcc gcc-c++ autoconf pcre pcre-devel make automake

yum -y install wget httpd-tools vim

查看 gcc版本

gcc -v
