python  -V
cd /data/soft;wget https://www.python.org/ftp/python/2.7.12/Python-2.7.12.tgz
tar -xvf Python-2.7.12.tgz;cd Python-2.7.12
./configure --prefix=/usr/local/python2.7  --enable-optimizations
make all &&make install&&make clean&&make distclean
/usr/local/python2.7/bin/python2.7 -V
Python 2.7.12
mv /usr/bin/python /usr/bin/python2.6.6
ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python
#有時會遇到2.7的模塊指定要用python2.7的命令。
ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python2.7
系統yum不支持2.7，需要指定一下：
vi /usr/bin/yum
# 修改 python 指向#!/usr/bin/python -> #!/usr/bin/python2.6.6
