有人可以提供在SUSE和RedHat上安装python 2.7版所需的步骤吗？它上面的版本就像2.4，我需要至少2.6才能使我的脚本工作。 所以在安装之后，我可以在xTerm中键入Python并获得Python 2.7命令行界面。

注意：您应该检查python 2.7.x的最新版本，因为它经常更新。目前（2017年10月），最新版本为2.7.14，但此评论将会变旧，新版本可能会每6个月左右发布一次。
wget https://www.python.org/ftp/python/2.7.14/Python-2.7.14.tgz # Download
tar xvfz Python-2.7.14.tgz # unzip
cd Python-2.7.14 # go into directory
./configure
make # build
su # or 'sudo su' if there is no root user
make altinstall
（编辑：make install - ＆gt;根据Ignacio的评论制作altinstall。）

RHEL 6.2 使用（有Python 2.6，我需要 Python 2.7.3 ）所以：
$ sudo sh -c 'wget -qO- http://people.redhat.com/bkabrda/scl_python27.repo >> /etc/yum.repos.d/scl.repo'
$ yum search python27

jimbob博士接受的答案（使用make altinstall）让我大部分时间都在python2.7 /usr/local/bin，但我还需要安装一些第三方模块。好的方面是easy_install从你运行的Python版本获取其安装位置，但我发现我仍然需要为Python 2.7安装easy_install，否则我会得到ImportError: No module named pkg_resources。所以我这样做了：
wget http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg
sudo -i
export PATH=$PATH:/usr/local/bin
sh setuptools-0.6c11-py2.7.egg
exit
现在我在/ usr / local / bin中有easy_install和easy_install-2.7，前者覆盖了我系统的easy_install的2.6版本，所以我删除了它：
sudo rm /usr/local/bin/easy_install
现在我可以像这样安装2.7版Python的库：
sudo /usr/local/bin/easy_install-2.7 numpy

关于linux的好处，你仍然可以download the source并且在大多数系统上都有自己编译版本的所有工具。
为了通过键入python从xterm获取python cli，python bin目录必须位于系统路径变量中（Red Hat example，Suse example）

如果你需要pip和设置工具，请在制作python2.7之前安装openssl和opessl-devl
yum install openssl-devel
然后关注https://stackoverflow.com/a/4149444/429476
然后https://pypi.python.org/pypi/setuptools
wget https://bootstrap.pypa.io/ez_setup.py
python2.7 ez_setup.py
然后安装pip
wget https://bootstrap.pypa.io/get-pip.py
python2.7 get-pip.py
然后安装其他软件包pip2.7 install package_name

如果要在Oracle Linux上安装Python 2.7，可以按以下步骤操作：
在/etc/yum.repos.d/public-yum-ol6.repo中启用软件集合。
vim /etc/yum.repos.d/public-yum-ol6.repo
[public_ol6_software_collections]
name=Software Collection Library release 1.2 packages for Oracle Linux 6
(x86_64)
baseurl=[http://yum.oracle.com/repo/OracleLinux/OL6/SoftwareCollections12/x86_64/][1]
gpgkey=file:[///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle][2]

对yum存储库进行此更改后，您只需运行yum命令即可安装Python：
yum install gcc libffi libffi-devel python27 python27-python-devel openssl-devel python27-MySQL-python
使用跟随变量编辑bash_profile：
vim ~/.bash_profile
PATH=$PATH:$HOME/bin:/opt/rh/python27/root/usr/bin export PATH
LD_LIBRARY_PATH=/opt/rh/python27/root/usr/lib64 export LD_LIBRARY_PATH
PKG_CONFIG_PATH=/opt/rh/python27/root/usr/lib64/pkgconfig export PKG_CONFIG_PATH
现在你可以使用python2.7和pip来安装Python模块：
/opt/rh/python27/root/usr/bin/pip install pynacl
/opt/rh/python27/root/usr/bin/python2.7 --version
