如果不安装python-urlgrabber，python-pycurl，yum-metadata-parser这3个包的话，在下面运行./yummain.py install yum的话会报以下错误：
报错如下
如果上述rpm连接失效，请到这里去一个一个的找：http://rpm.pbone.net/
报错1： [root@akinlau yum-3.4.3]# ./yummain.py Traceback (most recent call last): File “./yummain.py”, line 28, in <module> from yum import Errors File “/root/nagios/yum-3.4.3/yum/__init__.py”, line 52, in <module> import config File “/root/nagios/yum-3.4.3/yum/config.py”, line 30, in <module> from parser import ConfigPreProcessor, varReplace File “/root/nagios/yum-3.4.3/yum/parser.py”, line 4, in <module> import urlgrabber ImportError: No module named urlgrabber
报错2： [root@akinlau yum-3.4.3]# ./yummain.py Traceback (most recent call last): File “./yummain.py”, line 28, in <module> from yum import Errors File “/root/nagios/yum-3.4.3/yum/__init__.py”, line 55, in <module> import rpmsack File “/root/nagios/yum-3.4.3/yum/rpmsack.py”, line 38, in <module> import yum.depsolve File “/root/nagios/yum-3.4.3/yum/depsolve.py”, line 30, in <module> from transactioninfo import TransactionMember File “/root/nagios/yum-3.4.3/yum/transactioninfo.py”, line 32, in <module> from sqlitesack import YumAvailablePackageSqlite File “/root/nagios/yum-3.4.3/yum/sqlitesack.py”, line 26, in <module> import yumRepo File “/root/nagios/yum-3.4.3/yum/yumRepo.py”, line 33, in <module> import sqlitecachec ImportError: No module named sqlitecachec
创建yum配置文件
[root@akinlau ~] touch /etc/yum.conf
注：如果不创建yum.conf的话，下面运行./yummain.py install yum的话会报以下错误：
[root@akinlau yum-3.4.3]# ./yummain.py CRITICAL:yum.cli:Config Error: Error accessing file for config file:///etc/yum.conf
下载yum源码包并安装
[root@akinlau ~] wget http://yum.baseurl.org/download/3.4/yum-3.4.3.tar.gz
解压源码包[root@akinlau ~] tar zxvf yum-3.4.3.tar.gz
编译安装yum[root@akinlau ~] cd yum-3.4.3
[root@akinlau 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

出现以上提示就证明yum已经安装成功了。
