Linux中yum管理工具被誤刪的問題怎么解決

本篇內容介紹了“Linux中yum管理工具被誤刪的問題怎么解決”的有關知識，在實際案例的操作過程中，不少人都會遇到這樣的困境，接下來就讓小編帶領大家學習一下如何處理這些情況吧！希望大家仔細閱讀，能夠學有所成！

今天在安裝程序時，發現有一個插件未安裝，我就隨手敲了一個命令,看都沒看

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

這個粗心的手誤倒不至于讓整個系統癱瘓，yum 卻無法使用了。于是，我試著折騰了一番

代碼如下:

 rpm -ivh  --nodeps <a href="http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm">http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm</a>  
 rpm -ivh  --nodeps <a href="http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpm">http://mirrors.163.com/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://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-3.2.22-26.el5.centos.noarch.rpm[/code">http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-3.2.22-26.el5.centos.noarch.rpm[/code</a>]
關于rpm --nodeps的解釋
[code]
--nodeps                         don't verify package dependencies

接下來，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://wiki.linux.duke.edu/YumFaq">http://wiki.linux.duke.edu/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://mirrors.163.com/centos/5/os/x86_64/CentOS/libxml2-2.6.26-2.1.2.8.x86_64.rpm[/code">http://mirrors.163.com/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，結果正常了，大喜
