Centos7下安裝yum工具

需求

如果不小心在機器上卸載了yum工具，或者yum工具被破壞了，需要重新裝yum工具

 

1、卸載yum源

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

 

2、下載相關關於yum源的包

wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-iniparse-0.4-9.el7.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-167.el7.centos.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-53.el7.noarch.rpm

 

注：這里的yum包如果下載不了了，可以在此站點http://mirrors.163.com/centos/7/os/x86_64/Packages/ 找到對應的包下載

 

3、安裝包

rpm -ivh python-iniparse-0.4-9.el7.noarch.rpm   # 先安裝python-iniparse
rpm --nodeps --force -ivh yum-*                 # 在安裝相關的yum包，這里忽略關聯包  使用--nodeps --force

 

4、重新清理yum

yum clean all
yum makecache
