Python学习——（1）Centos安装Flask

一、环境

[root@localhost myproject]# cat /proc/version

centos6.5

Linux version 2.6.32-642.11.1.el6.i686
(mockbuild@c1bm.rdu2.centos.org) (gcc version 4.4.7 20120313 (Red
Hat 4.4.7-17) (GCC) ) #1 SMP Fri Nov 18 18:48:28 UTC 2016

二、操作

1、

yum
groupinstall
"Development
tools"

2、

yum
install
zlib-devel
bzip2-devel
openssl-devel ncurses-devel sqlite-devel

3、

替换默认的python2.6.6

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

vim
/usr/bin/yum将#!/usr/bin/python
替换成#!/usr/bin/python2.6.6（因为python2.7不支持yum）

wget
https://www.python.org/ftp/python/2.7.11/Python-2.7.11.tgz

tar vxf Python-2.7.11.tgz

cd Python-2.7.11.tgz

./configure --prefix=/usr/local

make && make install

4、安装pip

第一种方法（离线安装）

wget
https://pypi.python.org/packages/ff/d4/209f4939c49e31f5524fa0027bf1c8ec3107abaf7c61fdaad704a648c281/setuptools-21.0.0.tar.gz#md5=81964fdb89534118707742e6d1a1ddb4

tar vxf setuptools-21.0.0.tar.gz
cd setuptools-21.0.0
python setup.py  install

第二种方法（在线安装）

wget https://bootstrap.pypa.io/get-pip.pypython2.7

get-pip.py

修改环境变量

vim /etc/profile添加export PATH=$PATH:/hom  
 e/wang/Python2.7.10/bin执行生效source
