django项目部署到服务器

1.安装python
[root@dsc1 nginx]# python -V
Python 3.6.5

2.安装数据库
yum install mysql mysql-devel
yum install sqlite-devel

3.安装django

[root@dsc1 mydjango]# pip3 install django
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting django

  Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.",)': /simple/django/

  Could not find a version that satisfies the requirement django (from versions: )
No matching distribution found for django

解决办法:
yum install openssl-devel
重新编译安装python3

3.项目打包

4.上传到指定目录解压
[root@dsc1 soft]#mkdir /deploy
[root@dsc1 soft]# mv mydjango.rar /deploy/
[root@dsc1 deploy]# cd /deploy/
[root@dsc1 deploy]# rar x mydjango.rar
windows下的rar文件上传到linux后需要安装rar才能解压

有依赖的需要安装依赖
[root@dsc1 mydjango]#cd /deploy/mydjango
[root@dsc1 mydjango]#pip3 install -r requirements.txt

5.先测试一下不使用Nginx和uWSGI,django能不能正常运行

[root@dsc1 mydjango]# cd /deploy/mydjango
[root@dsc1 mydjango]# python3 manage.py runserver
Watching for file changes with StatReloader
Performing system checks...

System check identified no issues (0 silenced).

Django version 3.2.25, using settings 'mydjango.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

指定本机ip访问
python3 manage.py runserver 192.168.1.102:8000

浏览器输入:
http://192.168.1.102:8000/

6.安装uwsgi
[root@dsc1 mydjango]#pip3 install uwsgi
[root@dsc1 mydjango]# uwsgi --version
2.0.25.1

7.在项目里配置uwsgi.ini配置文件
a.在settings.py所在目录vim新文件 项目名称.ini
[root@dsc1 mydjango]# cd /deploy/mydjango/mydjango
[root@dsc1 mydjango]# echo>mydjango.ini

b.配置 项目名称.ini文件

vi mydjango.ini

[uwsgi]
master=true
chdir=/deploy/mydjango
module=mydjango.wsgi
py-autoreload=1
lazy-apps=true  
socket=127.0.0.1:8000
processes=4
buffer-size=32768
daemonize=uwsgi.log
log-maxsize = 5000000
vacuum = true
disable-logging = true

c.检查settings.py配置并收集项目静态文件

settings.py配置:

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, '/static/')
STATICFILES_DIRS = [
  os.path.join(BASE_DIR, '../mydjango/static'),  ## 实际静态文件所在项目路径，亲测好使
]

url.py配置:

from django.contrib import admin
from django.urls import path

urlpatterns = [
    path('admin/', admin.site.urls),
]

d.执行收集静态文件命令

[root@dsc1 mydjango]# mkdir -p /deploy/mydjango/static
[root@dsc1 mydjango]# cd /deploy/mydjango
[root@dsc1 mydjango]# python manage.py collectstatic

128 static files copied to '/static'.

这里会自动创建/static目录

8.启动测试
## 在当前目录启动
[root@dsc1 mydjango]# cd /deploy/mydjango/mydjango
[root@dsc1 mydjango]# uwsgi -i mydjango.ini
[uWSGI] getting INI configuration from mydjango.ini

## 启动之后查看进程

[root@dsc1 mydjango]# ps -ef | grep uwsgi
root     18835     1  0 11:06 ?        00:00:00 uwsgi -i mydjango.ini
root     18836 18835  1 11:06 ?        00:00:00 uwsgi -i mydjango.ini
root     18837 18835  2 11:06 ?        00:00:00 uwsgi -i mydjango.ini
root     18838 18835  2 11:06 ?        00:00:00 uwsgi -i mydjango.ini
root     18839 18835  2 11:06 ?        00:00:00 uwsgi -i mydjango.ini
root     18849 16852  0 11:06 pts/2    00:00:00 grep --color=auto uwsgi

查看日志:

[root@dsc1 mydjango]# tail -200f uwsgi.log
*** Operational MODE: preforking ***

服务正常启动

9.创建文件验证

[root@dsc1 mydjango]# cd /deploy/mydjango/mydjango
vi test.py
输入如下内容:

def application(env, start_response):
    start_response('200 OK', [('Content-Type','text/html')])
    return [b"Hello World"]

执行如下命令(Ctrl + C 中断会话):
uwsgi --http :8080 --wsgi-file /deploy/mydjango/mydjango/test.py

10.浏览器访问
http://127.0.0.1:8080

或者是通过本机ip访问
http://192.168.1.102:8080/
