2、安装基础包
1)安装基础包
apt-get -y install gcc make python-dev python-
setuptools python curl tree
2)使用easy_install命令安装pip
easy_install pip
二、安装uwsgi并测试访问
1、安装uwsgi
pip install uwsgi
2、查看已安装模块
pip list

total 1340
-rwxr-xr-x 1 root staff 281 Nov 19 09:32 pip
-rwxr-xr-x 1 root staff 283 Nov 19 09:32 pip2
-rwxr-xr-x 1 root staff 287 Nov 19 09:32 pip2.7
-rwxr-xr-x 1 root staff 1357088 Nov 19 09:34 uwsgi
4、创建test.py
root@10.1.10.236:~# cat /root/test.py
#!/usr/bin/python
# -*- coding: utf-8 -*-
#--------------------------------------------------
#Author:jimmygong
#Email:jimmygong@taomee.com
#FileName:test.py
#Function:
#Version:1.0
#Created:2015-11-19
#--------------------------------------------------
def application(env,start_response):
start_response('200 OK',[('Content_Type','text/html')])
return "uwsgi testing ok!"
5、启动服务
root@10.1.10.236:~# uwsgi --http :9999 --wsgi-file test.py
6、查看进程
root@10.1.10.236:~# ps -ef |grep uwsgi
root 2037 1833 0 10:01 pts/1 00:00:00 uwsgi --http :9999 --wsgi-file test.py
root 2038 2037 0 10:01 pts/1 00:00:00 uwsgi --http :9999 --wsgi-file test.py
root 2042 731 0 10:02 pts/0 00:00:00 grep --color=auto uwsgi
7、查看端口
root@10.1.10.236:~# netstat -tupnl |grep 9999
tcp 0 0 0.0.0.0:9999 0.0.0.0:* LISTEN 2037/uwsgi
8、访问
9、关闭服务
kill -9 2037
三、安装django并测试访问
1、安装django
pip install django
2、验证模块和查看版本
3、创建django项目所存放的目录
root@10.1.10.236:~# mkdir /opt/django -p
4、创建aaabbbcom项目
root@10.1.10.236:~# cd /opt/django/ && django-admin startproject aaabbbcom
5、查看下aaabbbcom项目目录结构
1)root@10.1.10.236:django# tree aaabbbcom/
aaabbbcom/
├── aaabbbcom
│ ├── __init__.py
│ ├── settings.py
│ ├── urls.py
│ └── wsgi.py
└── manage.py
1 directory, 5 files
2)目录结构说明
__init__.py 目录结构 调用有关
settings.py 项目设置
urls.py 地址配置文件
wsgi.py 部署
服务器文件
6、启动服务
cd aaabbbcom/ && nohup python manage.py runserver 0.0.0.0:8888 &
7、查看进程
ps -ef |grep python
root 2413 2412 0 15:14 pts/2 00:00:00 python manage.py runserver 0.0.0.0:8888
root 2416 2413 1 15:14 pts/2 00:00:04 /usr/bin/python manage.py runserver 0.0.0.0:8888
8、查看端口
netstat -tupnl |grep python
tcp 0 0 0.0.0.0:8888 0.0.0.0:* LISTEN 2416/python
9、访问
10、关闭服务
kill -9 2416
11、创建aaabbbcom项目下的testapp应用
cd /opt/django/aaabbbcom && python manage.py startapp testapp
12、查看下testapp目录结构
root@10.1.10.236:aaabbbcom# tree testapp/
testapp/
├── admin.py
├── __init__.py
├── migrations
│ └── __init__.py
├── models.py
├── tests.py
└── views.py
1 directory, 6 files
13、备份下settings.py配置
cp /opt/django/aaabbbcom/aaabbbcom/settings.py /opt/django/aaabbbcom/aaabbbcom/settings.py.bak
14、修改settings.py配置
root@10.1.10.236:~# diff /opt/django/aaabbbcom/aaabbbcom/settings.py /opt/django/aaabbbcom/aaabbbcom/settings.py.bak
40d39
< 'testapp',
15、定义视图函数views.py
root@10.1.10.236:~# cat /opt/django/aaabbbcom/testapp/views.py
#!/usr/bin/python
# -*- coding: utf-8 -*-
#--------------------------------------------------
#Author:jimmygong

#Function:
#Version:1.0
#Created:2015-11-19
#--------------------------------------------------
from django.http import HttpResponse
def index(request):
return HttpResponse("welcome django web!")
16、定义视图函数相关的urls.py
root@10.1.10.236:~# cat /opt/django/aaabbbcom/aaabbbcom/urls.py
from django.conf.urls import patterns,include,url
from django.contrib import admin
admin.autodiscover()
urlpatterns=patterns('',
url(r'^$','testapp.views.index',name='home'),
url(r'^admin/',include(admin.site.urls)),
)
17、启动服务
cd /opt/django/aaabbbcom/ && nohup python manage.py runserver 0.0.0.0:8888 &
18、访问
19、关闭服务
四、配置django和uwsgi结合
1、启动服务
uwsgi --http :7777 --chdir /opt/django/aaabbbcom/ --module aaabbbcom.wsgi
2、查看端口
netstat -tupnl |grep uwsgi
tcp 0 0 127.0.0.1:42415 0.0.0.0:* LISTEN 2587/uwsgi
tcp 0 0 0.0.0.0:7777 0.0.0.0:* LISTEN 2587/uwsgi
3、查看进程
ps -ef |grep wsgi
root 2587 779 0 15:43 pts/1 00:00:00 uwsgi --http :7777 --chdir /opt/django/aaabbbcom/ --module aaabbbcom.wsgi
root 2588 2587 0 15:43 pts/1 00:00:00 uwsgi --http :7777 --chdir /opt/django/aaabbbcom/ --module aaabbbcom.wsgi
root 2604 740 0 15:47 pts/0 00:00:00 grep --color=auto wsgi
4、访问
5、关闭服务
kill -9 2587
五、配置nginx和uwsgi结合
1、安装nginx
apt-get -y install nginx
2、创建aaabbbcom站点
cat /etc/nginx/sites-enabled/aaabbbcom
server {
listen 10.1.10.236:80;
server_name 10.1.10.236;
access_log /opt/django/access.log;
error_log /opt/django/error.log;
location / {
include /etc/nginx/uwsgi_params;
uwsgi_pass 127.0.0.1:8630;
}
}
3、删除默认default节点
rm -f /etc/nginx/sites-enabled/default
4、创建django.ini配置文件
cat /opt/django/django.ini
[uwsgi]
vhost=true
socket=127.0.0.1:8630
chdir=/opt/django/aaabbbcom
module=aaabbbcom.wsgi
master=true
processes=2
threads=2
max-requests=6000
chmod-socket=664
vacuum=true
daemonize=/opt/django/django.log
5、启uwsgi服务
nohup /usr/local/bin/uwsgi --ini /opt/django/django.ini &
6、重启nginx服务
/etc/init.d/nginx restart
[ ok ] Restarting nginx (via systemctl): nginx.service.
7、查看端口
netstat -tupnl|egrep "uwsgi|nginx"
tcp 0 0 10.1.10.236:80 0.0.0.0:* LISTEN 3433/nginx -g daemo
tcp 0 0 127.0.0.1:8630 0.0.0.0:* LISTEN 3408/uwsgi
8、查看进程
ps -ef |egrep "uwsgi|nginx"
root 3408 740 0 16:12 pts/0 00:00:00 /usr/local/bin/uwsgi --ini /opt/django/django.ini
root 3411 3408 0 16:12 pts/0 00:00:00 /usr/local/bin/uwsgi --ini /opt/django/django.ini
root 3412 3408 0 16:12 pts/0 00:00:00 /usr/local/bin/uwsgi --ini /opt/django/django.ini
root 3433 1 0 16:13 ? 00:00:00 nginx: master process /usr/sbin/nginx -g daemon on; master_process on;
www-data 3435 3433 0 16:13 ? 00:00:00 nginx: worker process

root 3476 779 0 16:16 pts/1 00:00:00 grep -E uwsgi|nginx
9、访问
10、查看相关日志
1)cat /opt/django/access.log

11、配置说明
socket:指定uwsgi的客户端将要连接的socket的路径
processes:开启的进程数量
workers:开启的进程数量，等同于processes（官网的说法是spawn the specified number of workers / processes）
chdir:指定运行目录（chdir to specified directory before apps loading）
wsgi-file:加载指定的WSGI文件（与Graham的mod_wsgi形式兼容）
stats:在指定的地址上，开启状态服务（enable the stats server on the specified address）
threads:开启线程 *** 作模式。你必须指定每个工作进程的线程数
master:启动主进程
daemonize:使进程在后台运行，并将日志打到指定的日志文件或者udp服务器
pidfile:指定pid文件的位置，记录主进程的pid号
vacuum:当服务器退出的时候自动删除unix socket文件和pid文件
vhost:开启
虚拟主机模式
module:加载指定的python WSGI模块（模块路径必须在PYTHONPATH里）
max-requests:为每个工作进程设置请求数的上限
limit-as:通过使用POSIX/UNIX的setrlimit()函数来限制每个uWSGI进程的虚拟内存使用数
chmod-socket:unix socket是个文件，所以会受到unix系统的权限限制。如果你的uwsgi客户端没有权限访问uWSGI socket，你可以用这个选项设置unix socket的权限
