CentOS配置源、wget、ifconfig基礎環境

執行命令:html

curl http://10.200.0.14:8000/portal.cgi -X POST -d 'username=lishuai&password=test@cetc38&language=0&submit=submit'

以便訪問外網linux

執行命令:git

ping www.baidu.com

報錯:centos

name or service not know

首先,添加dns服務器:緩存

vi /etc/resolv.conf

在文件中添加以下兩行:服務器

nameserver 8.8.8.8
nameserver 8.8.4.4

仍然不行!網絡

打算進行網絡配置,首先查看當前網絡設置信息:curl

ifconfig

返回信息:url

ifconfig: command not found

打算安裝ifconfig:spa

rpm install ifconfig

返回信息:

Cannot find a valid baseurl for repo: poptop-stable/7

打算從新配置源:

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

返回信息:

wget: command not found

只能手動下載rpm包並安裝,首先查看當前CentOS的版本:

rpm -q centos-release

返回信息:

centos-release-7-3.1611.el7.centos.x86_64

打開網址:http://mirrors.163.com/centos/7/os/x86_64/Packages/

下載文件:

net-tools-2.0-0.24.20131004git.el7.x86_64.rpm

wget-1.14-18.el7.x86_64.rpm

手動安裝:

rpm -ivh wget-1.14-18.el7.x86_64.rpm
rpm -ivh net-tools-2.0-0.24.20131004git.el7.x86_64.rpm

下載配置源的文件:

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

把原有的源配置文件改成.repo.bak,備份放入文件夾bak

清除源緩存並從新創建:

yum clean all
yum makecache

ping如今也能正常使用
