首先安装Python
我安装了两个版本:
Python-2.7.10.tgz
Python-3.5.1.tgz
首先看一下系统自带的Python版本：
1 [root@zk src]# python -V2 Python 2.6.6
安装Python2.7版本：
[root@zk src]# tar zxvf Python-2.7.10.tgz
[root@zk src]# cd Python-2.7.10
[root@zk Python-2.7.10]# ./configure --prefix=/usr/local/python27
[root@zk Python-2.7.10]# make && make install
把原来Python版本备份：
[root@zk Python-2.7.10]# mv /usr/bin/python /usr/bin/python_old
建立Python2.7软连接：
1 [root@zk Python-2.7.10]# ln -s /usr/local/python27/bin/python /usr/bin/python2 [root@zk Python-2.7.10]# python -V3 Python 2.7.10
安装Python3.5版本：
1 [root@zk src]# tar zxvf Python-3.5.1.tgz2 [root@zk src]# cd Python-3.5.13 [root@zk Python-3.5.1]# ./configure --prefix=/usr/local/python34 [root@zk Python-3.5.1]# make && make install5 [root@zk Python-3.5.1]# ln -s /usr/local/python3/bin/python3 /usr/bin/python36 [root@zk Python-3.5.1]# python3 -V7 Python 3.5.1
开始安装pip
首先下载pip:
1 [root@zk src]# wget "/packages/source/p/pip/pip-1.5.4.tar.gz#md5=834b2904f92d46aaa333267fb1c922bb" --no-check-certificate
解压安装：
1 [root@zk src]# tar -zxvf pip-1.5.4.tar.gz2 [root@zk src]# cd pip-1.5.43 [root@zk pip-1.5.4]# python setup.py install4 Traceback (most recent call last):5 File "setup.py", line 6, in
6 from setuptools import setup, find_packages7 ImportError: No module named setuptools
看到“ImportError: No module named setuptools”，缺少setuptools模块
下载安装setuptools模块：
[root@zk src]# wget --no-check-certificate /packages/source/s/setuptools/setuptools-12.0.3.tar.gz#md5=f07e4b0f4c1c9368fcd980d888b29a65
[root@zk src]# tar zxvf setuptools-12.0.3.tar.gz
[root@zk setuptools-12.0.3]# python setup.py build
[root@zk setuptools-12.0.3]# python setup.py install
***
z = zipfile.ZipFile(zip_filename, mode, compression=compression)
File "/usr/local/python27/lib/python2.7/zipfile.py", line 736, in __init__
"Compression requires the (missing) zlib module"
RuntimeError: Compression requires the (missing) zlib module
看到缺少zlib模块,解决方法：
[root@zk setuptools-12.0.3]# yum install zlib zlib-devel
安装完成之后需要重新编译Python2.7和3.5：
[root@zk setuptools-12.0.3]# cd ../Python-2.7.10
[root@zk Python-2.7.10]# ./configure --prefix=/usr/local/python27/
[root@zk Python-2.7.10]# make && make install
[root@zk Python-2.7.10]# rm -rf /usr/bin/python
[root@zk Python-2.7.10]# rm -rf /usr/bin/python3
[root@zk Python-2.7.10]# ln -s /usr/local/python27/bin/python /usr/bin/python
[root@zk Python-2.7.10]# cd ../setuptools-12.0.3
[root@zk setuptools-12.0.3]# python setup.py build
running build
running build_py
[root@zk setuptools-12.0.3]# python setup.py install
***
Processing dependencies for setuptools==12.0.3
Finished processing dependencies for setuptools==12.0.3
重新安装之后成功了！但是现在只是把setuptools安装好了，在重新安装pip：
[root@zk pip-1.5.4]# python setup.py install
Installed /usr/local/python27/lib/python2.7/site-packages/pip-1.5.4-py2.7.egg
Processing dependencies for pip==1.5.4
Finished processing dependencies for pip==1.5.4
[root@zk pip-1.5.4]# python -m pip install a
/usr/bin/python: cannot import name HTTPSHandler; 'pip' is a package and cannot be directly executed
根据上面提示又是缺少HTTPSHandler模块，安装：
[root@zk ~]# yum install openssl openssl-devel -y
然后再重新安装编译Python，安装完成时候在重新安装pip：
[root@zk ~]# python

~ok,已经成功了！
如果安装的时候不出问题是最好的，所以在安装软件的时候一点要先把依赖包安装好！
