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 folder
cd 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
pip install django
1). django-admin startproject proName
2). cd proName
3). python manage.py runserver # run
官网: https://uwsgi-docs.readthedocs.io/en/latest/WSGIquickstart.html#installing-uwsgi-with-python-support
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.py
def application(env, start_response):
start_response(‘200 OK‘, [(‘Content-Type‘,‘text/html‘)])
return [b"Hello World"] # python3
uwsgi --http :8080 --wsgi-file test.py # 假设访问端口号8080
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
python manage.py runserver 0.0.0.0:8000
uwsgi --http :8080 --module djangoProName.wsgi
--module djangoProName.wsgi 代表 djangoProName 目录下的 wsgi.py 文件
http://serverIP:8080
官网: https://www.nginx.com/resources/wiki/start/topics/tutorials/install/
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。
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
}
}
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 dir
chdir = /root/Odin/TrackManagement/TrackManagement/ ; django project dir
wsgi-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
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
uwsgi: unrecognized option ‘--http:8089‘
```(venv) [root@localhost TrackManagement]# uwsgi --http:8089 --module TrackManagement.wsgi
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
uwsgi: unrecognized option ‘--http‘
```
(venv) [root@localhost TrackManagement]# uwsgi --http:8089 --module TrackManagement.wsgi
uwsgi: unrecognized option ‘--http‘
getopt_long() error
```
#### 原因:
uwsgi还在开启 先杀了进程再重启
uwsgi trkMngm_uwsgi.ini -> invalid request block size: 21573 (max 4096)...skip
启动了之后每次访问
```

```
#### 原因:
trkMngm_uwsgi.ini 文件中有设置nginx的socket
这时候nginx还没加上 所以会有这个错误
ModuleNotFoundError: No module named ‘TrackManagement/TrackManagement/wsgi‘
```

#### 原因: 应该在TrackManagement项目里面运行 即这个目录下面
```
(venv) [root@localhost TrackManagement]# ls
db.sqlite3 manage.py testUwsgi.py TrackManagement
```
runserver运行django error : Bad Request
```
(venv) [root@localhost TrackManagement]# python manage.py runserver 0.0.0.0:8080

Django version 2.1.7, using settings ‘TrackManagement.settings‘
Starting development server at http://0.0.0.0:8080/
Quit the server with CONTROL-C.
Invalid HTTP_HOST header: ‘10.41.95.85:8080‘. You may need to add ‘10.41.95.85‘ to ALLOWED_HOSTS.
Bad Request: /

```
#### solution
django setting.py
```
ALLOWED_HOSTS = [‘*‘] -> ALLOWED_HOSTS = [‘*‘]
```
manage.py语法错误
```
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
virtualvenv+django+uWSGI+nginx部署
