yum故障最終解決辦法.移魂版 bash:yum:command not found

以下腳本使用前請用dos2unix進行轉碼

centos系列可以不用轉碼

 

CentOS 6.4 rpm -aq|grep yum|xargs rpm -e --nodeps//此命令爲卸載自帶的yum

 

#總結本文的目的是由於我自己yum故障，在網上找了很多方法均不完全活着根本不能成功，故此總結於此，希望能對才入門的同學有所幫助；我也是才接觸CENTOS不久

我會把我&&Linux的點點滴滴記錄下來，希望能幫助

sh 該腳本後如若還有問題，那可能是版本問題以下的方法對此問題可能有幫助

1.下載repo文件
1.wget http://mirrors.163.com/.help/CentOS6-Base-163.repo      #你也可以將此地址更換

2.備份並替換系統的repo文件
1.[root@localhost ~]# cd /etc/yum.repos.d/
2.[root@localhost ~]# mv CentOS-Base.repo CentOS-Base.repo.bak
3.[root@localhost ~]# mv CentOS6-Base-163.repo CentOS-Base.repo

3.執行yum源更新
1.[root@localhost ~]# yum clean all
2.[root@localhost ~]# yum makecache
3.[root@localhost ~]# yum update

 

希望對大家有所幫助！
