根据pip官网说明，使用get-pip.py安装失败。
官网说明Note
The get-pip.py script is supported on the same python version as pip. For the now unsupported Python 2.6, alternate script is available here.
下载get-pip.py
curl https://bootstrap.pypa.io/2.6/get-pip.py -o get-pip.py
安装pip
注意：使用python2.6.6安装，因为我的环境中python指向的是2.6.6，所以直接使用下面命令进得安装。
python get-pip.py
报错如下
[root@javen-zhao pip2.6]# python get-pip.py
DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

根据网上方法安装python时使用./configure –with-ssl也不行。经过多次尝试，使用如下命令安装python 2.6.6后可以正常安装pip。
./configure –prefix=/usr/local –with-ssl –enable-optimizations
其中–prefix=/usr/local是指定python安装的路径，安装后python2.6可执行脚本会在/usr/local/bin目录下
注意：做上面操作时检查一下系统中是否有安装openssl-devel
检查openssl安装情况
[root@javen-zhao pip]# rpm -aq|grep openssl
openssl-devel-1.0.1e-57.el6.x86_64
openssl-1.0.1e-57.el6.x86_64
如果没有openssl-devel使用yum 安装
[root@javen-zhao pip]# yum install openssl-devel
重新安装pip，安装成功后查看2.6.6环境下的pip版本信息
[root@javen-zhao pip2.6]# pip2.6 -V
pip 9.0.3 from /usr/local/lib/python2.6/site-packages (python 2.6)
[root@javen-zhao pip2.6]# whereis pip
pip: /usr/bin/pip /usr/bin/pip2.7 /usr/local/bin/pip2.6 /usr/local/bin/pip
安装成功。
