基本环境

yum -y install wget gcc xz tar

安装 zlib （如果不装zlib setuptools可能报错 "Compression requires the (missing) zlib module"）

    1. wget http://prdownloads.sourceforge.net/libpng/zlib-1.2.11.tar.gz?download

　2. tar -xvf zlib-1.2.11.tar.gz 

　3. cd zlib-1.2.11  &&  ./configure && make && make install

安装 python

1. wget https://www.python.org/ftp/python/2.7.12/Python-2.7.12.tar.xz

2. xz -d Python-2.7.12.tar.xz && tar -xvf Python-2.7.12.tar 

3. cd Python-2.7.12 && ./configure && make && makeinstall

4. mv /usr/bin/python /usr/bin/python2.6.6

5. ln -s /usr/local/bin/python /usr/bin/python

6. vim /usr/bin/yum

7. 修改头部 #!/usr/bin/python2.6.6

如果python 报错”error while loading sharedlibraries: libpython2.7.so.1.0: cannot open shared object file: No such file ordirectory”

vim /etc/ld.so.conf 下一行加 /usr/local/lib  然后执行  /sbin/ldconfig -v
