Linux中yum管理工具被誤刪的解決辦法

Linux中yum管理工具被誤刪的解決辦法

這篇文章主要介紹了Linux中yum管理工具被誤?的解決辦法,需要的朋友可以參考下

今天在安裝程序時(shí)，發(fā)現有一個(gè)插件未安裝，我就隨手敲了一個(gè)命令,看都沒(méi)看

代碼如下:

yum remove yum

然后就杯具了...

代碼如下:

[root@localhost ~]# yum

-bash: /usr/bin/yum: No such file or directory

這個(gè)粗心的手誤倒不至于讓整個(gè)系統癱瘓，yum 卻無(wú)法使用了。于是，我試著(zhù)重新安裝

代碼如下:

rpm -ivh --nodeps <a href="http://www.tjdsmy.cn/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm">http://www.tjdsmy.cn/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm</a>

rpm -ivh --nodeps <a href="http://www.tjdsmy.cn/centos/5/os/x86_64/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpm">http://www.tjdsmy.cn/centos/5/os/x86_64/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpm</a>

rpm -ivh --nodeps <a href="http://www.tjdsmy.cn/centos/5/os/x86_64/CentOS/yum-3.2.22-26.el5.centos.noarch.rpm[/code">http://www.tjdsmy.cn/centos/5/os/x86_64/CentOS/yum-3.2.22-26.el5.centos.noarch.rpm[/code</a>]

關(guān)于rpm --nodeps的解釋

[code]

--nodeps don't verify package dependencies

接下來(lái)，再次嘗試輸入yum,結果再次出現莫名錯誤

代碼如下:

[root@localhost ~]# yum

There was a problem importing one of the Python modules

required to run yum. The error leading to this problem was:

libxml2.so.2: cannot open shared object file: No such file or directory

Please install a package which provides this module, or

verify that the module is installed correctly.

It's possible that the above module doesn't match the

current version of Python, which is:

2.4.3 (#1, Nov 11 2010, 13:30:19)

[GCC 4.1.2 20080704 (Red Hat 4.1.2-48)]

If you cannot solve this problem yourself, please go to

the yum faq at:

<a href="http://www.tjdsmy.cn/YumFaq">http://www.tjdsmy.cn/YumFaq</a>

因為yum調用的是python,運行 Python，試下是否可行

代碼如下:

[root@localhost~]# python

Python 2.4.3 (#1, Nov 11 2010, 13:30:19)

[GCC 4.1.2 20080704 Red Hat 4.1.2-48)] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> import yum

Traceback (most recent call last):

File "<stdin>", line 1, in ?

File "/usr/lib/python2.4/site-packages/yum/__init__.py", line 54, in ?

import transactioninfo

File "/usr/lib/python2.4/site-packages/yum/transactioninfo.py", line 31, in ?

from sqlitesack import YumAvailablePackageSqlite

File "/usr/lib/python2.4/site-packages/yum/sqlitesack.py", line 26, in ?

import yumRepo

File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 32, in ?

import sqlitecachec

File "/usr/lib64/python2.4/site-packages/sqlitecachec.py", line 19, in ?

import _sqlitecache

ImportError: libxml2.so.2: cannot open shared object file: No such file or directory

>>>

提示缺少libxml2.so.2，安裝一下試試

代碼如下:

rpm -ivh <a href="http://www.tjdsmy.cn/centos/5/os/x86_64/CentOS/libxml2-2.6.26-2.1.2.8.x86_64.rpm[/code">http://www.tjdsmy.cn/centos/5/os/x86_64/CentOS/libxml2-2.6.26-2.1.2.8.x86_64.rpm[/code</a>]

再次測試運行下yum命令，結果終于正常了
