cd /data/tools
wget http://www.python.org/ftp/python/2.7.6/Python-2.7.6.tgz
# tar xvzf Python-2.7.6.tgz
# cd Python-2.7.6
# ./configure --prefix=/usr/local --enable-shared
# make && make install
安装了python2.7，第一次执行时报错：
error while loading shared libraries: libpython2.7.so.1.0: cannot open shared object file: No such file or directory
解决方法如下：
find / -name libpython2.7.so.1.0
vi /etc/ld.so.conf
添加上python2.7的lib库地址，如我的/usr/local/lib，保存文件
/sbin/ldconfig -v
#mv /usr/bin/python /usr/bin/python2.6.6
#ln -s /usr/local/bin/python2.7 /usr/bin/python
python -V
vi /usr/bin/yum
将文件头部的
#!/usr/bin/python
改成
#!/usr/bin/python2.6.6
