标题: Linux教程之CentOS修正Yum的更新源教程
小知识：CentOS（CommunityEnterpriseOperatingSystem，中文意思是：社区企业操作系统）是Linux发行版之一。
CentOS默许的yum更新源是从镜像列表猎取的，体系会依据你的速率及区域主动检测一个速率较快的更新源并利用此更新源。假如CentOS在国际，却利用外洋的源，或默许的源没法毗连，则必要手动修正更新源列表了。


1、编纂源设置文件

  1. vim/etc/yum.repos.d/CentOS-Base.repo
复制代码
默许的源以下：
#CentOS-Base.repo
#
#ThemirrorsystemusestheconnectingIPaddressoftheclientandthe
#updatestatusofeachmirrortopickmirrorsthatareupdatedtoand
#geographicallyclosetotheclient.
YoushouldusethisforCentOSupdates
#unlessyouaremanuallypickingothermirrors.
#
#Ifthemirrorlist=doesnotworkforyou,asafallbackyoucantrythe
#remarkedoutbaseurl=lineinstead.
#
#
[base]
name=CentOS-$releasever-Base
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
#releasedupdates
[updates]
name=CentOS-$releasever-Updates
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
#baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
#packagesused/producedinthebuildbutnotreleased
[addons]
name=CentOS-$releasever-Addons
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=addons
#baseurl=http://mirror.centos.org/centos/$releasever/addons/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
#additionalpackagesthatmaybeuseful
[extras]
name=CentOS-$releasever-Extras
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras
#baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/

#baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/
gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

[contrib]
name=CentOS-$releasever-Contrib
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=contrib
#baseurl=http://mirror.centos.org/centos/$releasever/contrib/$basearch/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
2、修正源


假如要修正为网易的源，则把一切内容交换为：
#CentOS-Base.repo
#
#ThemirrorsystemusestheconnectingIPaddressoftheclientandthe
#updatestatusofeachmirrortopickmirrorsthatareupdatedtoand
#geographicallyclosetotheclient.YoushouldusethisforCentOSupdates
#unlessyouaremanuallypickingothermirrors.
#
#Ifthemirrorlist=doesnotworkforyou,asafallbackyoucantrythe
#remarkedoutbaseurl=lineinstead.
#
#
[base]
name=CentOS-$releasever-Base
baseurl=http://mirrors.163.com/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
[updates]
name=CentOS-$releasever-Updates
baseurl=http://mirrors.163.com/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
[addons]
name=CentOS-$releasever-Addons
baseurl=http://mirrors.163.com/centos/$releasever/addons/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
[extras]
name=CentOS-$releasever-Extras
baseurl=http://mirrors.163.com/centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

[centosplus]
name=CentOS-$releasever-Plus
baseurl=http://mirrors.163.com/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
最初，实行以下下令，更新组件
  1. yumupdate

对我们学习操作系统有很大的帮助，加深我们对OS的理解。?

其实老师让写心得我也没怎么找资料应付，自己想到什么就写些什么，所以不免有些凌乱；很少提到编程，因为那些在实验报告里已经说了，这里再写就多余了。

请问谁有Linux的学习心得的吗？简单的说说？

随着实验课程的结束，理论课也该结束了，说实话教OS的这两位老师是我们遇到过的不错的老师（这话放这可能不太恰当）.
