    [root@localhost app]# xz -d Python-2.7.13.tar.xz
    [root@localhost app]# tar xf Python-2.7.13.tar
    [root@localhost Python-2.7.13]# ./configure --enable-optimizations --prefix=/mnt/app/python.2.7.13
    [root@localhost Python-2.7.13]# make -j 4
    [root@localhost Python-2.7.13]# make -j 4 install

    [root@localhost Python-2.7.13]# ln -s /mnt/app/python.2.7.13 /mnt/app/python

    补充: python升级版本后,yum不可用,解决方法:
    CentOS6:
    [root@localhost Python-2.7.13]# sed -i s/python/python2.6/g /usr/bin/yum
    CentOS7:
    [root@localhost Python-2.7.13]# sed -i s/python/python2.7/g /usr/bin/yum
    [root@localhost Python-2.7.13]# sed -i s/python/python2.7/g /usr/libexec/urlgrabber-ext-down
