linux安装Django 以及 生产环境部署实现高并发

1.首先安装python

Python编译安装

主要介绍linux环境下安装

cd  /usr/local/src     //进入安装目录

wget  https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz

xz  -d    Python-3.6.2.tar.xz   && tar  xvf  Python-3.6.2.tar  //解压缩

cd  Python-3.6.2  //进入解压目录

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

make && make install

/usr/local/python/bin/python3.6  --version   //查看当前python版本

ln -s  /usr/local/python/bin/python3.6   /usr/bin/python3.6   //作软连接

ln -s  /usr/local/python/bin/pip3   /usr/bin/pip3

2.安装Django

pip3 install  Django

cd  /usr/local/python/bin   //进入文件夹

ln -s /usr/local/python/bin/django-admin    /usr/bin/django-admin   //建立django-admin 工程的软连接

cd /home   //进入任意一个目录

django-admin   startproject  mysite   //建立工程

进入mysite工程下同名目录mysqite  修改settings  若是用的是mysql  pip3 install pymysql

须要:

yum -y install mysql-devel

pip3 install mysqlclient

3.启动Django

在settings中找到ALLOWED_HOSTS=[],加入主机名或者域名

python3.6  manager.py  runserver  ip:port  

 

安装uwsgi

pip3  install uwsgi

基本测试：

vim  /home/test.py 

# test.py
def application(env, start_response):
    start_response('200 OK', [('Content-Type','text/html')])
    return [b"Hello World"] # python3
    #return ["Hello World"] # python2

 

运行：

/usr/local/python/bin/uwsgi --http :8000 --wsgi-file  /home/test.py

 

用uwsgi 启动django

cd mysite  #进入django项目主目录下
/usr/local/python/bin/uwsgi  --http :8900  --module  mysite.wsgi  

 

也能够把参数写到配置文件里

vim  /home/EasyBlog.ini

[uwsgi]
http = :9900   
#the local unix socket file than commnuincate to Nginx
socket = 127.0.0.1:9901     #socket nginx监听端口
# the base directory (full path)
chdir = /home/EasyBlog# Django's wsgi file
wsgi-file = EasyBlog/wsgi.py
# maximum number of worker processes
processes = 4
#thread numbers startched in each worker process
threads = 2

#monitor uwsgi status
stats = 127.0.0.1:9191
# clear environment on exit
vacuum          = true

 

启动

    
/usr/local/python/bin/uwsgi   /home/EasyBlog.ini

 

安装nginx配合nginx使用

vim  /data/nginx/conf/uwsgi.conf

upstream django {
    server 127.0.0.1:9901; #端口为监听uwsgi的socket端口
}

server {
    listen      80;
    server_name blog.fuzegame.com;
    charset     utf-8;

    client_max_body_size 75M;   # adjust to taste

    location /media  {
        alias /path/to/your/mysite/media;  # your Django project's media files - amend as required
    }

    location /static {
        alias /home/EasyBlog/static; # your Django project's static files - amend as required  配置静态文件路径
    }

    location / {
        uwsgi_pass  django;
        include     /home/EasyBlog/uwsgi_params; # the uwsgi_params file you installed
    }
}

 

重要：把 nginx conf配置文件夹下的 uwsgi_params  拷贝到 django 目录下

 cp  /usr/local/nginx/conf/uwsgi_params     /home/EasyBlog

 在生产环境中，应该把django settings中的Debug= False

这样配置完成后 访问admin页面时看不到静态文件，能够这样操做

在 django settings   添加一行   

STATIC_ROOT = 'all_static_files'

 而后执行：

python3 manage.py collectstatic

 执行完成后会在django工程目录下 自动建立一个 all_static_files  目录

最后还须要在nginx 中的django配置文件中 修改

location /static {
        alias /data/mysite/all_static_files; # 修改为all_static_files
    }

 

重启nginx

 

此时启动Nginx 和Uwsgi，你的django项目就能够实现高并发啦！
