yum故障最终解决办法.移魂版 bash:yum:command not found

以下脚本使用前请用dos2unix进行转码

centos系列可以不用转码

 

CentOS 6.4 rpm -aq|grep yum|xargs rpm -e --nodeps//此命令为卸载自带的yum

 

#总结本文的目的是由于我自己yum故障，在网上找了很多方法均不完全活着根本不能成功，故此总结于此，希望能对才入门的同学有所帮助；我也是才接触CENTOS不久

我会把我&&Linux的点点滴滴记录下来，希望能帮助

sh 该脚本后如若还有问题，那可能是版本问题以下的方法对此问题可能有帮助

1.下载repo文件
1.wget http://mirrors.163.com/.help/CentOS6-Base-163.repo      #你也可以将此地址更换

2.备份并替换系统的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.执行yum源更新
1.[root@localhost ~]# yum clean all
2.[root@localhost ~]# yum makecache
3.[root@localhost ~]# yum update

 

希望对大家有所帮助！
