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 //做软链接

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 //创建django-admin 工程的软链接

cd /home //进入任意一个目录

django-admin startproject mysite //创建工程

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

需要:

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

也可以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，可以这样操作

在 django settings 添加一行

STATIC_ROOT = 'all_static_files'

然后执行：

python3 manage.py collectstatic

执行完成后会在django工程目录下自动创建一个 all_static_files 目录

最后还需要在nginx 中的django配置文件中修改

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

重启nginx

此时启动Nginx 和Uwsgi，你的django项目就可以实现高并发啦！
