The yum command on CentOS deletes the restore remediation method

Preface

Because the server centos6.8 installed MySQL has been unable to connect the problem, and then see a method, accidentally put Yum to delete, all can not restore, is desperate, very uncomfortable. Then, without Yum, this centos would feel like a waste, and then find a way to put it up.

Python--version view python version
 whereis python view python file
 python:/usr/bin/python2.6/usr/bin/python/usr/lib/ python2.7/usr/lib/python2.6/usr/lib64/python2.7/usr/lib64/python2.6/usr/include/python2.7/usr/share/man/man1/ Python.1.gz

centos6.8 basic underlying Python is python2.6, Centos7 is 2.7, mine is centos6.8 solution

method One:

This netizen solves the method, records the

$ RPM-QA | grep python-| grep 2.6
$ sudo rpm-ivh--force--nodeps ftp://mirror.switch.ch/pool/4/mirror/scientificlinux/6.5/x86_64/updates /fastbugs/python-2.6.6-52.el6.x86_64.rpm

To solve the problem, yum can be used, and the principle estimate is that Python rolls back to the default of 2.6

Method Two:

This is my solution.

http://mirrors.163.com/centos/6/os/x86_64/Packages/

1, to the above site to download the following RPM package

     python-iniparse-0.3.1-2.1.el6.noarch.rpm
     yum-metadata-parser-1.1.2-14.1.el6.x86_64.rpm 
     yum-3.2.29-69.el6.centos.noarch.rpm
     yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm

2. After the download is complete, install it with the RPM command as follows:

     RPM-IVH--force--nodeps python-iniparse-0.3.1-2.1.el6.noarch.rpm
     rpm-ivh--force--nodeps yum-metadata-parser-1.1.2-14.1.el6.x86_64.rpm 
     RPM-IVH--force--nodeps  yum-3.2.29-69.el6.centos.noarch.rpm 
     yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm

3, to Http://yum.baseurl.org/wiki

       Download yum-3.4.3.tar.gz, put it in the directory you specified, unzip the command as follows:
       tar-zxvf yum-3.4.3.tar.gz     #解压后进到yum -3.4.3 Directory

4, input./yummain.py update

When you are finished, enter Yum to resolve the issue

It is also useless to pay attention to the version of CentOS and the compatibility of this installation package when downloading the installation package above. Reference
