基于Nginx 和 uwsgi 搭建 django.

2022-08-21 07:45:36

第一篇博客，不是很懂语法之类的，希望通过多写点东西，记录自己的成长，早点成为一个pyer.

就写下这两天折腾的这个nginx-uwsgi-django.

首先附上官方文档链接 http://uwsgi-docs.readthedocs.io/en/latest/tutorials/Django_and_nginx.html

环境 python == Python 2.7.3, os == centos6.5 x86_64

django == 1.8.1

uwsgi == uWSGI 2.0.15 (64bit) #都是pip 直接安装的

nginx == 1.10.1 #yum install -y

1.刚刚创建的project

$django-admin startproject test_nginx_uwsgi

$cd test_nginx_uwsgi/

$tree

.

├── manage.py

└── test_nginx_uwsgi

    ├── __init__.py

    ├── settings.py

    ├── urls.py

    └── wsgi.py

2.当前目录下创建test.py文件，代码如下：

#test.py

def application(env, start_response):

    start_response('200 OK', [('Content-Type','text/html')])

    return "Hello World" #国际惯例,helloworld

运行代码：

$uwsgi --http : --wsgi-file test.py

##中间东西很多,又看不懂，乱七八糟的,我就不贴了##

*** uWSGI is running in multiple interpreter mode ***

spawned uWSGI worker  (and the only) (pid: , cores: )

参数含义简介：

:9111 > 想必大家都知道，运行的端口
wsgi-file > 指定加载的文件
报错[uwsgi: command not found]的话，ln -s /your-python-dir/bin/* /usr/bin/*

如图所示，第一步完成！

3.测试您的django 是否能够正常运行！ps:为了方便起见我们直接用admin网站测试好了~~

$python manage.py syncdb #创建superuser

$python manage.py makemigration

$python manage.py migrate

$python manage.py runserver 0.0.0.0:

大家有目共睹

4.使用Uwsgi 跑 django项目

cmd: (其中test_nginx_uwsgi.wsgi指的就是test_nginx_uwsgi目录下的wsgi.py，django1.8自动生成)

$ uwsgi --http : --module test_nginx_uwsgi.wsgi

又成功了一步~可以对比上面的，同样的url，这里却很难看，是因为没有加载static文件

但是可以说明 web-client <-> Uwsgi <-> Django 是连通的,下面的就要看Nginx.

5.配置Nginx.

由于版本的问题，如果这里也用官方的源码就不行了。

收集静态文件

#首先setting.py中添加

STATIC_ROOT = '/root/django/test_nginx_uwsgi/static_root/'
------------------------------我是换行------------------------------

$python manage.py collectstatic

You have requested to collect static files at the destination

location as specified in your settings:

    /root/django/test_nginx_uwsgi/static_root

This will overwrite existing files!

Are you sure you want to do this?

Type 'yes' to continue, or 'no' to cancel: yes

#·······省略~

 static files copied to '/root/django/test_nginx_uwsgi/static_root'.

nginx配置文件在 /etc/nginx/nginx.conf ,其中include -> /etc/nginx/conf.d/*.conf [这个，相信大多数linux服务如出一辙]

vi /etc/nginx/conf.d/test_nginx_uwsgi.conf,代码如下

# test_nginx_uwsgi.conf

# the upstream component nginx needs to connect to

upstream django_test { #加上_test，因为和原来的冲突了，这里备注下

    # server unix:///path/to/your/mysite/mysite.sock; # for a file socket

    server 127.0.0.1:; # for a web port socket (we'll use this first) 类似uwsgi端口

}

# configuration of the server

server {

    # the port your site will be served on

    listen      ;  #nginx 运行端口

    # the domain name it will serve for

    server_name .example.com; # substitute your machine's IP address or FQDN

    charset     utf-;

    # max upload size

    client_max_body_size 75M;   # adjust to taste

    # Django media

    location /media  {

        alias /root/django/test_nginx_uwsgi/media;  # 加载你的meida,

    }

    location /static {

        alias /root/django/test_nginx_uwsgi/static_root; # 加载你的静态文件

    }

    # Finally, send all non-media requests to the Django server.

    location / {

        uwsgi_pass  django_test;

        include     /etc/nginx/uwsgi_params; #官方说要把文件cp到项目目录，感觉没必要

    }

}

重启 nginx (不知道是我这机器有毛病还是····，光restart不行)

[root@lzy test_nginx_uwsgi]# /etc/init.d/nginx restart

stopping nginx.... Done.

starting nginx..

[root@lzy test_nginx_uwsgi]# nginx -c /etc/nginx/nginx.conf

[root@lzy test_nginx_uwsgi]# nginx -s reload

[root@lzy test_nginx_uwsgi]# lsof -i :

COMMAND  PID USER   FD   TYPE   DEVICE SIZE/OFF NODE NAME

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

nginx    root    9u  IPv4       0t0  TCP *: (LISTEN)

#可以看到8090端口已经在运行 nginx 了,说明配置文件有效果了

6.接下来官网Balala了一堆,我这种fish压根不懂，我也没按他的做，跳过这一步··

7.配置test_nginx_uwsgi_uwsgi.ini 启动配置文件

　　ps:参考了http://www.runoob.com/django/django-nginx-uwsgi.html

　　创建test_nginx_uwsgi_uwsgi.ini 就在项目根目录

#test_nginx_uwsgi.ini file

[uwsgi]

# Django-related settings

socket = :

# the base directory (full path)

chdir = /root/django/test_nginx_uwsgi

# Django s wsgi file

module = test_nginx_uwsgi.wsgi

# process-related settings

# master

master = true

# maximum number of worker processes

processes = 

# ... with appropriate permissions - may be needed

chmod-socket =

# clear environment on exit

vacuum = true

8.配置完成，就剩下启动了

启动就很简单呢

#首先启动uwsgi 指定配置文件ini

$uwsgi --ini test_nginx_uwsgi.ini #也可以 nohup uwsgi --ini test_nginx_uwsgi.ini & 后台执行，无输出

#其次重启Nginx,参照上面重启步骤

#浏览器打开 192.168.8.199:/admin

大功告成~现在就是通过nginx端口打开的django，如果nginx Listen 80，那么浏览器不用输端口也行呢

#error: /var/log/nginx/nginx.log提示 13 Pemmer deied【权限问题】，修改/etc/nginx/nginx.conf，user nginx -> user root
