CentOS下重新安裝yum

標籤：

1，下載最新的yum-3.2.28.tar.gz並解壓

#wget http://yum.baseurl.org/download/3.2/yum-3.2.28.tar.gz
#tar xvf yum-3.2.28.tar.gz

2，進入目錄，運行安裝

#cd yum-3.2.28
#./yummain.py install yum
如果提示錯誤： CRITICAL:yum.cli:Config Error: Error accessing file for config file:///etc/

是缺少設定檔。在etc目錄下面建立yum.conf檔案，然後再次運行 yummain.py install yum，順利完成安裝。

3，最後更新系統

#yum check-update
#yum update
#yum clean all

如果不安裝python-urlgrabber，python-pycurl，yum-metadata-parser這3個包的話，在下面運行./yummain.py install yum的話會報以下錯誤：

報錯如下

如果上述rpm串連失效，請到這裡去一個一個的找：http://rpm.pbone.net/

建立yum設定檔

[[email protected] ~] touch /etc/yum.conf

 

註：如果不建立yum.conf的話，下面運行./yummain.py install yum的話會報以下錯誤：

 

[[email protected] yum-3.4.3]# ./yummain.py  CRITICAL:yum.cli:Config Error: Error accessing file for config file:///etc/yum.conf

下載yum源碼包並安裝

[[email protected] ~] wget http://yum.baseurl.org/download/3.4/yum-3.4.3.tar.gz

解壓源碼包[[email protected] ~] tar zxvf yum-3.4.3.tar.gz

編譯安裝yum[[email protected] ~] cd yum-3.4.3

[[email protected] yum-3.4.3] ./yummain.py install yum

base                                                         | 3.7 kB     00:00   

base/primary_db                                              | 4.5 MB     00:07   

extras                                                       | 3.5 kB     00:00   

extras/primary_db                                            |  23 kB     00:03

出現以上提示就證明yum已經安裝成功了。
