Linux 系統為 CentOS Linux release 7.4.1708

重灌yum和python

 

1. 首先解除安裝現有python

   1.  

      rpm -qa|grep python|xargs rpm -ev --allmatches --nodeps #解除安裝python

   2.  

      whereis python |xargs rm -frv ##刪除所有殘餘檔案

   3.  

      whereis python ##驗證刪除，返回無結果

    

2.  刪除現有的yum

   1.  

      rpm -qa|grep yum|xargs rpm -ev --allmatches --nodeps #刪除yum

   2.  

      whereis yum |xargs rm -frv #刪除殘留檔案

   3.  

      whereis yum #驗證刪除完成

3. 找到下載檔案源
   首先在這裡找到伺服器對應的版本，如 7.4.1708 進入這裡目錄 找到對應版本的rpm，替換下面的檔案。

4. 下載並安裝，注意順序，先安裝python 然後 yum。不然安裝後還會報錯，重新來一遍。
