Nginx+uwsgi+web.py

基础案例

操作系统:Centos7
文件:
Python-2.7.13.tgz
下载地址:https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz
nginx-1.12.0.tar.gz
下载地址:http://nginx.org/download/nginx-1.12.0.tar.gz
uwsgi-2.0.15.tar.gz
下载地址:https://projects.unbit.it/downloads/uwsgi-2.0.15.tar.gz

1、安装Python

configure注意带参数--with-zlib,否则uwsgi会报错
tar -zxvf Python-2.7.13.tgz
cd Python-2.7.13
./configure --with-zlib
make
make install
make clean

python --version 可以查看版本
修改版本会导致一些小问题,可以尝试修改#!/usr/bin/python为#!/usr/bin/python2.7

2、安装配置nginx

安装没什么特别的
tar -zxvf nginx-1.12.0.tar.gz
cd nginx-1.12.0
./configure
make
make install
make clean

配置
如果没有自定义安装路径
nginx.conf文件默认路径为/usr/local/nginx/conf/nginx.conf
如果用yum安装配置路径为/etc/nginx/nginx.conf
可以试着查找
find /|grep nginx.conf
whereis nginx
修改nginx.conf 文件,不必担心改坏了,同目录下还有个nginx.conf.default
如果80端口有其它用处,可以把listen 80;改成其它端口,避免冲突
内容不妨先仿着server再写一个server与原来的server保持并列,

server {
  listen 2001;
  server_name [::]:2001 localhost;
  location / {
    include uwsgi_params;
    uwsgi_pass 127.0.0.1:8080;
  }
}

listen应该是监听,那么从外部访问应该访问2001端口
uwsgi_pass 127.0.0.1:8080;这句与proxy_pass看起来很像,向内转发数据,并且需要在8080端口上有监听,uwsgi会处理这事

启动nginx
/usr/local/nginx/sbin/nginx
可以带配置文件,默认用/usr/local/nginx/conf/nginx.conf

试着访问一下x.x.x.x:80与x.x.x.x:2001

3、写一个test.py

暂且放在/var/test/路径下

#!/usr/bin/python2.7
# -*- coding:utf-8 -*-
# test.py
import web
urls = (
  '/', 'index'
)
class index:
def GET(self):
return 'Hello, world!'
app = web.application(urls,globals())
# app.run()
application = app.wsgifunc()

如果没有web模块可以先pip install web.py
试试会不会报错python code.py

4、安装配置uwsgi

这里有更详细的说明
http://uwsgi-docs.readthedocs.io/en/latest/Install.html

tar -zxvf uwsgi-2.0.15.tar.gz
cd uwsgi-2.0.15
python uwsgiconfig.py --build

配置文件
支持多种格式,这里用ini
为code.py写一个配置文件test.uwsgi.ini

[uwsgi]
socket = 127.0.0.1:8080 #与nginx的uwsgi_pass对应
chdir = /var/test/
wsgi-file = test.py
processes = 4
threads = 2
stats = 127.0.0.1:2011
daemonize = ./uwsgi.log

启动
./uwsgi --wsgi-file test.uwsgi.ini
如果正常的话
curl x.x.x.x:2001
将会返回Hello,world
否则可以到uwsgi.log中查看错误信息

查看端口占用
lsof -i:80

报错整理:

urlopen error unknown url type: https

参考:http://www.xinotes.net/notes/note/628/

cd python源码目录/Modules
vi Setup.dist
找到并取消注释成

# Socket module helper for SSL support; you must comment out the other
# socket line above, and possibly edit the SSL variable:
SSL=/usr/local/ssl
_ssl _ssl.c \
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
-L$(SSL)/lib -lssl -lcrypto

重新安装
cd ..
./configure --with-zlib
make
make install

fatal error: openssl/sha.h: No such file or directory

参考:http://blog.csdn.net/xxxxxx91116/article/details/7927520

Centos 安装
yum install openssl-devel
