1. virtualvenv

virtualvenv install

首先要安装python3

因为系统已经装了 python3.6 所以接下来直接装虚拟环境 virtualvenv

mkdir yourwebproject foldercd yourwebproject/usr/python3.6/bin/python3.6 -m venv venv   #建立一个独立于系统的虚拟环境 不会跟系统环境混淆source venv/bin/activate                    #运行环境deactivate                                  #退出环境

2. django

• 运行虚拟环境，在环境中安装django

pip install django

• 新建项目

1). django-admin startproject proName           2). cd proName   3). python manage.py runserver    # run

• 新建app

不用也可以进行接下来的操作

3. uWSGI

官网：

安装

在虚拟环境中

pip install uwsgi

检测 uwsgi 是否正常工作

• 在与venv同目录下写一个模拟站点文件 test.py

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

• 运行

uwsgi --http :8080 --wsgi-file test.py  # 假设访问端口号8080

• 浏览器访问

http://serverIP:8080

若显示站点文件中的输出，说明uwsgi生效

路径 web client <-> uwsgi <-> python

部署 django

• 首先运行django确保django能正常工作

python manage.py runserver 0.0.0.0:8000

• 在manage.py同级目录下运行

uwsgi --http :8080 --module djangoProName.wsgi

--module djangoProName.wsgi 代表 djangoProName 目录下的 wsgi.py 文件

• 浏览器访问

http://serverIP:8080

4. nginx

官网:

不在虚拟环境中安装

由于服务器上已经安装了 nginx 所以安装步骤省略，只需要在 nginx.conf 中添加配置即可。

• 配置 nginx

nginx.conf 结构:

user www-data;worker_processes auto;pid /run/nginx.pid;events {    worker_connections 768;}http {   # server{ ... }}

添加 server

server {        listen       98 default_server;   # 访问时输入的端口 本地和外部浏览器后面都要加这个端口号        server_name  10.41.95.85;          # 自己网站的域名        # Load configuration files for the default server block.        include /etc/nginx/default.d/*.conf;                location / {                      # location : 文件系统配置 去应答一些要服务器资源的请求            include uwsgi_params;            uwsgi_pass 127.0.0.1:9898;    # 与ini文件对接端口 与上面的 93 端口没有关系        }    }

配置完了之后记得重启nginx

• 配置 uwsgi

将配置项全部写入ini文件

在venv同目录下自己新建uwsgi的ini文件

[uwsgi]socket = 127.0.0.1:9898                               ; 与 nginx 对接 IP; django pro dirchdir = /root/Odin/TrackManagement/TrackManagement/   ; django project dirwsgi-file = TrackManagement/wsgi.py                   ; 代表 TrackManagement 目录下的 wsgi.py 文件; module = TrackManagement.wsgi                       ; 有上面的wsgi配置这个就不用写了processes = 2                                         ; 进程threads = 1                                           ; 线程stats = 127.0.0.1:9696                                ; 内部配置访问ip 与socket区别开

• 浏览器访问

http://10.41.95.85:98

若显示django画面 则 uwsgi+nginx生效

路径 web client <-> nginx <-> uwsgi <-> django

接下来是过程中踩的坑

<details>

<summary>uwsgi: unrecognized option '--http:8089'</summary>

uwsgi: unrecognized option '--http:8089'getopt_long() error

原因:

参数格式不对 :8089前面要加空格 uwsgi还在开启

</details>

<details>

<summary>uwsgi: unrecognized option '--http'</summary>

(venv) [root@localhost TrackManagement]# uwsgi --http:8089 --module TrackManagement.wsgiuwsgi: unrecognized option '--http'getopt_long() error

原因:

uwsgi还在开启 先杀了进程再重启

</details>

<details><summary>uwsgi trkMngm_uwsgi.ini -> invalid request block size: 21573 (max 4096)...skip</summary>

启动了之后每次访问

原因:

trkMngm_uwsgi.ini 文件中有设置nginx的socket

如果这时候nginx没有对应的配置或者配置了但是nginx没有重启就会产生这个错误

<summary>manage.py语法错误</summary>

SyntaxError: invalid syntax[root@localhost TrackManagement]# python manage.py runserver 0.0.0.0:8080  File "manage.py", line 14    ) from exc

solution

没有运行虚拟环境 外面的环境是python 虚拟环境才是python3 所以会有语法错误
