centos7中 yum的安装

自己误将yum卸载，
在重装时由于依赖问题一直报错：
error: Failed dependencies:
    /usr/bin/python is needed by yum-3.4.3-163.el7.centos.noarch
    python >= 2.4 is needed by yum-3.4.3-163.el7.centos.noarch
    python(abi) = 2.7 is needed by yum-3.4.3-163.el7.centos.noarch
    python-iniparse is needed by yum-3.4.3-163.el7.centos.noarch
    python-sqlite is needed by yum-3.4.3-163.el7.centos.noarch
    python-urlgrabber >= 3.10-8 is needed by yum-3.4.3-163.el7.centos.noarch

1、查看yum安装包
# rpm -qa | grep yum
yum-plugin-fastestmirror-1.1.31-52.el7.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64
yum-utils-1.1.31-52.el7.noarch   
 
2、将其全部卸载
#rpm -e yum-plugin-fastestmirror-1.1.31-52.el7.noarch --nodeps
#rpm -e yum-metadata-parser-1.1.4-10.el7.x86_64 --nodeps
#rpm -e yum-utils-1.1.31-52.el7.noarch --nodeps
 
 
libxml2-python-2.9.1-6.el7_2.3.x86_64.rpm                    
python-ipaddress-1.0.16-2.el7.noarch.rpm  
lvm2-python-libs-2.02.185-2.el7.x86_64.rpm
python-kitchen-1.1.1-5.el7.noarch.rpm     
yum-3.4.3-163.el7.centos.noarch.rpm
python-2.7.5-86.el7.x86_64.rpm                                
python-libs-2.7.5-86.el7.x86_64.rpm       
yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
python-backports-ssl_match_hostname-3.5.0.1-1.el7.noarch.rpm  
python-pycurl-7.19.0-19.el7.x86_64.rpm    
yum-plugin-aliases-1.1.31-52.el7.noarch.rpm
python-chardet-2.2.1-3.el7.noarch.rpm                         
python-setuptools-0.9.8-7.el7.noarch.rpm  
yum-plugin-fastestmirror-1.1.31-52.el7.noarch.rpm
python-devel-2.7.5-86.el7.x86_64.rpm                          
python-urlgrabber-3.10-9.el7.noarch.rpm   
yum-plugin-protectbase-1.1.31-52.el7.noarch.rpm
python-iniparse-0.4-9.el7.noarch.rpm                          
rpm-python-4.11.3-40.el7.x86_64.rpm       
yum-utils-1.1.31-52.el7.noarch.rpm
 
 
4、下载完成后执行
#rpm -Uvh --replacepkgs lvm2-python-libs*.rpm --nodeps --force
#rpm -Uvh --replacepkgs libxml2-python*.rpm --nodeps --force
#rpm -Uvh --replacepkgs python*.rpm --nodeps --force
#rpm -Uvh --replacepkgs rpm-python*.rpm yum*.rpm --nodeps --force
 
 
5、包安装完成了，我们还需要配置yum的源地址

[root@hear oracle]# cd /etc/yum.repos.d/
[root@hear yum.repos.d]# ls
redhat.repo
[root@hear yum.repos.d]# wget http://mirrors.aliyun.com/repo/Centos-7.repo

2019-12-12 16:13:50 (223 MB/s) - ‘Centos-7.repo’ saved [2523/2523]

6.修改$releasever的值

[root@hear yum.repos.d]# ls
Centos-7.repo redhat.repo
[root@hear yum.repos.d]# sed -i 's/$releasever/7/g' /etc/yum.repos.d/Centos-7.repo
[root@hear yum.repos.d]# pwd
/etc/yum.repos.d
[root@hear yum.repos.d]# cat /etc/yum.conf

替换distroverpkg=centos-release   

替换成

distroverpkg=redhat-release 

 

6、最后执行yum makecache生成缓存

[root@hear yum.repos.d]# yum makecache

 全部注释后，再次执行 yum clean all；  yum makecache
.查看当前可用的仓库 yum repolist all

[root@hear yum.repos.d]# yum repolist all
