Redhat的yum配置步骤

 

Redhat的yum配置

Redhat Linux是免费的操作系统，但是里面的yum服务是收费的，有的时候我们安装软件必须从yum上面安装。虽然Redhat的yum是收费的，但我们可以使用CentOS的yum代替Redhat的yum，下面我们就要讲解一下如何安装。

---

1.检查系统是否安装了yum包

rpm -qa |grep yum

2.删除自带的yum包

rpm -qa|grep yum|xargs rpm -e --nodeps

因为一些包之间可能会有依赖关系，所以我们需要加上参数 --nodeps 无视依赖关系。

3.下载yum包

下载地址：http://mirrors.163.com/centos/

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-73.el6.centos.noarch.rpm

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm 
 

如果报错，请自行去开源网站下载

4.解压yum包

rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm

rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

rpm -ivh yum-3.2.29-73.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm

这里注意的是yum-3.2.29-73.el6.centos.noarch.rpm和yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm相互依赖，缺一不可，安装的时候必须同时安装才能

5.替换yum源

下载yum源，这里使用的是163的yum源

cd  /etc/yum.repos.d/                                         进入目录
wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo      下载到这个目录
vi CentOS6-Base-163.repo                                      编辑这个文件

如果是提前下载好CentOS6-Base，直接移动到/etc/yum.repos.d/就行

mv rhel-source.repo rhel-source.repo.bak
mv CentOS6-Base-163.repo rhel-source.repo

6. 编辑替换后的rhel-source.repo。

#rhel-source.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-6 - Base - 163.com

baseurl=http://mirrors.163.com/centos/6/os/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=os

gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

 

#released updates

[updates]

name=CentOS-6 - Updates - 163.com

baseurl=http://mirrors.163.com/centos/6/updates/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=updates

gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

 

#additional packages that may be useful

[extras]

name=CentOS-6 - Extras - 163.com

baseurl=http://mirrors.163.com/centos/6/extras/$basearch/

#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=extras

gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

7. 清理并重建缓存

yum clean all
yum makecache

8. 更新yum

yum update
