Centos6.4(64bit)安装Python2.7.10 & tornado-4.3

Centos6.4 安装Python2.7.10 & tornado-4.3

1、配置Centos6.4开发环境

安装相关依赖系统库

$ yum install wget gcc gcc-c++ zlib-devel gtk2-devel zip libart_lgpl-devel libXtst-devel -y

$ yum groupinstall "Development tools" -y

$ yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel -y

2、下载和安装Python

下载地址:https://www.python.org/ftp/python/2.7.10/Python-2.7.10.tgz

Python-2.7.10.tgz

$ tar zxf Python-2.7.10.tgz

$ cd Python-2.7.10

$ ./configure --prefix=/usr/local

$ make && make altinstall

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

$ ln -s /usr/local/bin/python2.7 /usr/bin/python

$ python -V

Python 2.7.10

$ yum list

There was a problem importing one of the Python modules

required to run yum. The error leading to this problem was:

No module named yum

Please install a package which provides this module, or

verify that the module is installed correctly.

It's possible that the above module doesn't match the

current version of Python

这是因为yum默认使用的python版本是2.6.6，到哪是现在的python版本是2.7.10，故会出现上述问题，只需要该一下yum的默认python配置版本就行了：

$vi /usr/bin/yum

将文件头部的$!/usr/bin/python改为

$!/usr/bin/python2.6

3、下载安装Tornado

下载地址:https://pypi.python.org/simple/tornado/ 有很多版本随便选

$ tar zxf tornado-4.3.tar.gz

$ cd tornado-4.3

$ python setup.py build

$ python setup.py install

创建测试文件

import tornado.ioloop

import tornado.web

class MainHandler(tornado.web.RequestHandler):

def get(self):

self.write("Hello, world")

application = tornado.web.Application([

(r"/", MainHandler),

])

if __name__ == "__main__":

application.listen(8888)

tornado.ioloop.IOLoop.instance().start()

4、运行文件

$ python tornado_example.py

然后打开浏览器，输入http://ip:8888就看到页面输出Hello, world了。
