自己誤將yum卸載,在重裝的時候一直報錯:
error: Failed dependencies:

找了網上的很多方法,下面是自己總結的一套親測有效的方法:
1,查看yum安裝包
# 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,將上面的安裝包全部卸載
#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
3,下載yum安裝包
