卸载掉RHEL6自带的YUM包。

    使用下列命令检查YUM的依赖关系。

rpm -qR yum

得到的依赖关系有：

[root@bogon doc]# rpm -qR yum-3.2.27-14.el6.noarch
/usr/bin/python
config(yum) = 3.2.27-14.el6
pygpgme
python >= 2.4
python(abi) = 2.6
python-iniparse
python-sqlite
python-urlgrabber >= 3.9.0-8
rpm >= 0:4.4.2
rpm-python
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(FileDigests) <= 4.6.0-1
rpmlib(PartialHardlinkSets) <= 4.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1
yum-metadata-parser >= 1.1.0
rpmlib(PayloadIsXz) <= 5.2-1
