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!
