yum是shell前端软件包管理器,是Linux下用来下载安装应用的软件,本篇文章重点为大家讲解一下Red Hat 中安装yum源具体方法。
设置步骤
\1. 查询原有的yum
[root@orcl ~]# rpm -qa |grep yum
yum-plugin-fastestmirror-1.1.30-37.el6.noarch
yum-metadata-parser-1.1.2-16.el6.i686
yum-utils-1.1.30-37.el6.noarch
yum-plugin-security-1.1.30-37.el6.noarch
yum-3.2.29-75.el6.centos.noarch
yum-rhn-plugin-0.9.1-43.el6.noarch
\2. 删除原有的yum
[root@orcl ~]# rpm -aq|grep yum|xargs rpm -e –-nodeps
[root@orcl ~]# rpm -qa |grep yum
[root@orcl ~]#
\3. 查询原有yum配置
[root@orcl ~]# whereis yum
yum: /etc/yum
[root@orcl ~]# rm -fr /etc/yum
\4. 下载需要的安装包 http://mirrors.163.com/centos/6.8/os/i386/Packages/ 系统为32的,所以我选择i386。64的自行查找x86_64。 可以使用
wget http://mirrors.163.com/centos/6.8/os/i386/Packages/yum-3.2.29-73.el6.centos.noarch.rpm
下载
yum-3.2.29-73.el6.centos.noarch.rpm
yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpm
yum-metadata-parser-1.1.2-16.el6.i686.rpm
Python-iniparse-0.3.1-2.1.el6.noarch.rpm
\5. 安装python
[root@orcl ~]# rpm -ivh python-iniparse-….noarch.rpm
warning: python-iniparse-0.4-9.el7.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY
error: Failed dependencies:
python(abi) = 2.7 is needed by python-iniparse-0.4-9.el7.noarch
当前安装版本与服务器不兼容,退后一个版本再试。 查看当前发行版本号
cat /etc/issue
遇到的错误
系统位数与安装程序包位数不一致 file /bin/ls
error: Failed dependencies:

libxml2.so.2(LIBXML2_2.4.30)(64bit) is needed by yum-metadata-parser-1.1.2-16.el6.x86_64
重新下载32位程序包
[root@orcl ~]# rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpmPreparing… ########################################### [100%]package python-iniparse-0.3.1-2.1.el6.noarch is already installed[root@orcl ~]# rpm -ivh yum-metadata-parser-1.1.2-16.el6.i686.rpmPreparing… ########################################### [100%]1:yum-metadata-parser ########################################### [100%][root@orcl ~]# rpm -ivh yum-3.2.29-73.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-37.el6.noarch.rpmPreparing… ########################################### [100%]1:yum-plugin-fastestmirro########################################### [ 50%]2:yum ########################################### [100%][root@orcl ~]#
注意最后两个包必需同时安装,否则会相互依赖 更改yum源(使用网易的CentOS镜像源)
[root@localhost yum]# cd /etc/yum.repos.d/[root@localhost yum.repos.d]# rm -rf *[root@localhost yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo[root@localhost yum.repos.d]# vi CentOS6-Base-163.repo
将所有 $releasever 修改为具体的版本号,我这里写的是6.8,这个自己打开(http://mirrors.163.com/centos)找一下就可以。
# 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.
