我相信我正在CA AppLogic 3.0上运行CentOS 5.5（64位）。
uname -a说

我升级了yum upgrade ，但我的Python仍然在版本2.4.3。
yum info python说

我想我读了一个地方， yum依靠python所以我不应该删除。 那么我应该下载Python版本2.7.x作为源代码并编译它？ 或者有没有办法用yum升级Python（不知何故）？
我正在计划使用Python的最新版本2.x的Django。
有epel回购的python26软件包。 这应该是更好，更容易的选项，然后手动安装。
但是，请注意，您可能无法用2.6或任何其他版本replace默认的python ，因为有很多东西为2.4构build，升级它将需要重新编译大量的软件包，所得到的系统将不会真的是CentOS 5.我觉得升级到CentOS 6比较容易，然后重build这么多的软件包。
是从源头上编译它：
yum install gcc gcc-c++.x86_64 compat-gcc-34-c++.x86_64 openssl-devel.x86_64 zlib*.x86_64
安装python 2.7
wget http://www.python.org/ftp/python/2.7/Python-2.7.tar.bz2 tar -xvjf Python-2.7.tar.bz2 cd Python* ./configure --prefix=/opt/python27 make make install vi ~/.bash_profile replace PATH=$PATH:$HOME/bin with PATH=$PATH:$HOME/bin:/opt/python27/bin
重新加载.bash_profile
source ~/.bash_profile echo "/opt/python27/lib" > /etc/ld.so.conf.d/python27.conf ldconfig
