通过yum install uwsgi 安装的uwsgi在进行测试的时候，发现版本是2.0.15,但是启动uwsgi测试的时候报参数错误，后来改用pip安装(先yum remove uwsgi删除老的uwsgi)就成功了。uwsgi安装完成之后的样子

安装pip

1. ?
   wget https://bootstrap.pypa.io/get-pip.py
2. ?
   python ./get-pip.py

安装uwsgi,一个干净的linux系统安装uwsgi过程中,会遇到以下两个错误。

1. ?
   Exception: you need a C compiler to build uWSGI
2. ?
   ----------------------------------------
3. ?
   Failed building wheel for uwsgi
4. ?
   Running setup.py clean for uwsgi
5. ?
   Failed to build uwsgi
6. ?
   Installing collected packages: uwsgi
7. ?
   Running setup.py install for uwsgi ... error

解决办法：yum install gcc-*

另外一个错误：

fatal error: Python.h: No such file or directory

解决办法：yum install python-devel

安装成功的打印信息：

编辑一个简单的测试文件hello.py：

1. ?
   def application(env,start_response):
2. ?
   start_response( ‘200 OK‘,[(‘Content-Type‘,‘text/html‘)])
3. ?
   return "Hello,world"

启动uwsgi : uwsgi --http-socket :80 --wsgi-file hello.py

1. ?
   [ [email?protected]_68_155_centos ~]# /usr/bin/uwsgi --http-socket :80 --wsgi-file hello.py
