Django项目使用uwsgi+nginx部署上线

Django项目使用uwsgi+nginx部署上线

前言

代码已经开发完成,正式部署上线

settings 配置

python 复制代码
DEBUG = False
ALLOWED_HOSTS = ['*']
...
# 静态资源
STATIC_URL = '/static/'
STATICFILES_DIRS = [ BASE_DIR / 'StaticFiles']
STATIC_ROOT = os.path.join(BASE_DIR, 'Allstatic')
# or
# STATIC_ROOT = BASE_DIR / 'Allstatic'  # 资源部署

# 媒体资源
MEDIA_URL = '/media/'
MEDIA_ROOT = BASE_DIR / 'media'
python 复制代码
python manage.py collectstatic  # 按照 STATIC_ROOT 收集静态文件
python 复制代码
项目下urls.py
from django.contrib import admin
from django.urls import path, include, re_path
from rest_framework.documentation import include_docs_urls
from django.views.static import serve
from django.conf import settings

urlpatterns = [
    path('admin/', admin.site.urls),
    ...
    # django改为上线模式后,不再提供静态文件服务,需要添加静态资源的路由信息
    re_path('static/(?P<path>.*)', serve, {'document_root': settings.STATIC_ROOT}, name='static')
    # 定义媒体资源的路由信息
    re_path('media/(?P<path>.*)', serve, {'document_root': settings.MEDIA_ROOT}, name='media'),
]

安装uwsgi 和配置uwsgi

python 复制代码
安装uWSGI
pip3 install uwsgi
测试uWSGI是否安装成功
在终端中输入以下命令查看uwsgi的版本号,如果输出正常,说明uswgi已安装成功
$ uwsgi --version
2.0.15
python 复制代码
如果想要运行项目来测试

# uwsgi --http :8000 --chdir 项目路径 -w 项目.wsgi 静态文件地址--static-map=/static=static

uwsgi --http :8000 --chdir /home/teacher/ -w teacher.wsgi --static-map=/static=static

推荐配置文件启用wsgi

不使用nginx的配置(不推荐)

python 复制代码
uwsgi.ini
[uwsgi]
# 项目绝对路径
chdir = /home/cooper/projects/foo/web1
# 监听的端口,当没有nginx时使用这个
http = 0.0.0.0:8000
# 静态资源代理  映射目录,实际静态目录
static-map = /static= /home/cooper/projects/foo/web1/Allstatic
# 主应用中的wsgi文件
wsgi-file = /home/cooper/projects/foo/web1/web1/wsgi.py

# 启动一个master进程来管理其他的子进程
master = True
# 开启四个进程
processes = 4
# 两个线程
thread = 2
# 设置每个工作进程处理请求上限,达到上限时,将回收/重启,可预防内存泄漏
max-request = 5000
# 服务停止时自动移除unix socket和pid 文件
vacuum = True

# uwsgi 日志
#daemonize = /root/Server/logs/uwsgi.log
logto = /home/cooper/projects/foo/web1/logs/ty_log.log  # 需要创建logs文件夹
# 日志格式化
logformat = %(ltime) | pid:%(pid) wid:%(wid) | %(proto) %(status) | %(method) | %(host)%(uri) | request_body_size:%(cl) | response_body_size:%(rsize)

# 服务的pid记录文件
pidfile = uwsgi.pid

# 指定虚拟环境 绝对地址到bin文件夹前
# virtualenv = /home/venv

使用nginx的配置

python 复制代码
uwsgi.ini
[uwsgi]
# 项目绝对路径
chdir = /home/cooper/projects/foo/web1
;套接字方式的IP地址:端口号【此模式需要有nginx,如果只用uwsgi的话可以忽略此项】
;socket=0.0.0.0:8000
# 主应用中的wsgi文件
wsgi-file = /home/cooper/projects/foo/web1/web1/wsgi.py

# 启动一个master进程来管理其他的子进程
master = True
# 开启四个进程
processes = 4
# 两个线程
thread = 2
# 设置每个工作进程处理请求上限,达到上限时,将回收/重启,可预防内存泄漏
max-request = 5000
# 服务停止时自动移除unix socket和pid 文件
vacuum = True

# uwsgi 日志
#daemonize = /root/Server/logs/uwsgi.log
logto = /home/cooper/projects/foo/web1/logs/ty_log.log
# 日志格式化
logformat = %(ltime) | pid:%(pid) wid:%(wid) | %(proto) %(status) | %(method) | %(host)%(uri) | request_body_size:%(cl) | response_body_size:%(rsize)

# 服务的pid记录文件
pidfile = uwsgi.pid

# 指定虚拟环境 绝对地址到bin文件夹前
# virtualenv = /home/venv

安装 nginx和配置

python 复制代码
yum install nginx -y  安装

systemctl start nginx   启动
systemctl stop nginx   停止
systemctl status nginx  查看状态
systemctl restart nginx  重启
systemctl enable nginx  开机自启动

niginx 配置

python 复制代码
安装nginx后,默认的配置文件在
/etc/nginx/nginx.conf
修改nginx.conf
python 复制代码
