python安装

1.下载python

​​https://www.python.org/downloads/release/python-352/​​

2.安装依赖的包

yum install -y bzip2-devel ncurses-devel gdbm-devel openssl-devel readline-devel zlib-devel sqlite-devel

3.安装python

tar zxvf Python-3.5.2.tgz 
cd /lost+found/Python-3.5.2
./configure --prefix=/usr/local/python

make
make install

4.进入python命令行模式

cd /usr/local/python/bin
./python3.5

退出命令 exit()

5.替换系统默认的2.6python

mv /usr/bin/python /usr/bin/python2.6
ln -s /usr/local/python/bin/python2.7  /usr/bin/python

这个时候输入python进行验证

由于升级python后，导致了yum与python的不兼容

需要修改yum

vim /usr/bin/yum

第一行改成：#!/usr/bin/python2.6即可，由于yum不兼容python2.7所以改成2.6即可

安装PIL扩展

yum install python-devel
