CentOS 7 系统安装初始化之yum,linux系统使用起步

一、下载如下python-[]及yum-[ ],四个安装包,并用如下命令安装

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

rpm -ivh --force --nodeps python-iniparse*

rpm -ivh --force --nodeps yum-metadata-parse*

rpm -ivh --force --nodeps yum-3.4.3-168.el7.*

rpm -ivh --force --nodeps yum-plugin-fastestmirror-*

rpm -ivh --force --nodeps yum-cron-3.4.3*

二、配置阿里巴巴YUM源

1、备份本机yum配置文件:CentOS-Base.repo

cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2、下载阿里巴巴YUM源

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

或者

curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo3

3、升级、清除、生成yum缓存(本地缓存必须的yum仓库源里的包资源,本机使用)

yum upgrade # 升级yum

yum clean all # 清除系统所有的yum缓存

yum makecache # 生成yum缓存

三、配置阿里巴巴epel-7.repo的YUM源

alibaba epel:

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

yum upgrade # update the yum

yum clean all # 清除系统所有的yum缓存

yum makecache # 生成yum缓存

四、配置清华大学的repo的YUM源:复制CentOS-Base.repo:下所有内容,替换原CentOS-Base.repo里全部内容,按步骤操作,记得备份此文件

Qinghua repo:

cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

vim /etc/yum.repos.d/CentOS-Base.repo

CentOS-Base.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.

[base]

name=CentOS-$releasever - Base

baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/os/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever\&arch=$basearch\&repo=os

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#released updates

[updates]

name=CentOS-$releasever - Updates

baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/updates/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever\&arch=$basearch\&repo=updates

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that may be useful

[extras]

name=CentOS-$releasever - Extras

baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/extras/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever\&arch=$basearch\&repo=extras

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that extend functionality of existing packages

[centosplus]

name=CentOS-$releasever - Plus

baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/centosplus/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever\&arch=$basearch\&repo=centosplus

gpgcheck=1

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

yum upgrade # update the yum

yum clean all # 清除系统所有的yum缓存

yum makecache # 生成yum缓存

五、配置RPM-GPG-KEY-EPEL-7文件

cd /etc/pki/rpm-gpg

wget https://archive.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-7

六、安装如下支持软件包

yum install -y htop

yum install -y epel-release

七、安装NTFS硬盘格式支持:即windows下的硬盘,加载显示在linux的CentOS 7系统里

yum install ntfs-3g

备注:打开NTFS格式的磁盘时,如果是用户账户,则需要输入root账户密码。此为CentOS 7的安全管理。
