linux安裝Django 以及 生產環境部署實現高併發

1.首先安裝python

Python編譯安裝

主要介紹linux環境下安裝

cd  /usr/local/src     //進入安裝目錄

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  //解壓縮

cd  Python-3.6.2  //進入解壓目錄

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

make && make install

/usr/local/python/bin/python3.6  --version   //查看當前python版本

ln -s  /usr/local/python/bin/python3.6   /usr/bin/python3.6   //作軟連接

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

2.安裝Django

pip3 install  Django

cd  /usr/local/python/bin   //進入文件夾

ln -s /usr/local/python/bin/django-admin    /usr/bin/django-admin   //建立django-admin 工程的軟連接

cd /home   //進入任意一個目錄

django-admin   startproject  mysite   //建立工程

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

須要:

yum -y install mysql-devel

pip3 install mysqlclient

3.啓動Django

在settings中找到ALLOWED_HOSTS=[],加入主機名或者域名

python3.6  manager.py  runserver  ip:port  

 

安裝uwsgi

pip3  install uwsgi

基本測試：

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

 

運行：

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

 

用uwsgi 啓動django

cd mysite  #進入django項目主目錄下
/usr/local/python/bin/uwsgi  --http :8900  --module  mysite.wsgi  

 

也能夠把參數寫到配置文件裏

vim  /home/EasyBlog.ini

[uwsgi]
http = :9900   
#the local unix socket file than commnuincate to Nginx
socket = 127.0.0.1:9901     #socket nginx監聽端口
# 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

 

啓動

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

 

安裝nginx配合nginx使用

vim  /data/nginx/conf/uwsgi.conf

upstream django {
    server 127.0.0.1:9901; #端口爲監聽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  配置靜態文件路徑
    }

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

 

重要：把 nginx conf配置文件夾下的 uwsgi_params  拷貝到 django 目錄下

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

 在生產環境中，應該把django settings中的Debug= False

這樣配置完成後 訪問admin頁面時看不到靜態文件，能夠這樣操做

在 django settings   添加一行   

STATIC_ROOT = 'all_static_files'

 而後執行：

python3 manage.py collectstatic

 執行完成後會在django工程目錄下 自動建立一個 all_static_files  目錄

最後還須要在nginx 中的django配置文件中 修改

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

 

重啓nginx

 

此時啓動Nginx 和Uwsgi，你的django項目就能夠實現高併發啦！
