CentOS服务器配置Nginx、uwsgi实现Android文件上传功能

系统准备

首先，我们安装yum-utils，一个yum的拓展库，能够实现完整得yum功能和插件
sudo yum -y install yum-utils
接下来安卓CentOS开发者工具，用于编译源代码
sudo yum -y groupinstall development

安装python3

安装IUS
sudo yum -y install https://centos7.iuscommunity.org/ius-release.rpm
安装最新版本python
sudo yum -y install python36u
检查python版本
python3.6 -V
接下来安装python36u0devel包，提供了python3环境下需要的库和头文件
sudo yum -y install python36u-devel

配置虚拟环境

虚拟环境可以提供独立的环境给不同的python项目，保证你的项目有独立的依赖不会干扰到其他项目 。每个编程环境都可以安装不同的python库
选择一个路径去放置python编程环境
cd opt/
mkdir python-virtual-dev
cd python-virtual-dev
python-3.6 demo
接着进入该环境
source demo/bin/activate
安装django库
pip install django
安装uwsgi
pip install uwsgi

配置Nginx

安装
yum -y install eqel-release
yum repolist
yum install nignx
安装完打开nginx服务
systemctl start nginx
并且测试初始页是否能完成服务
X.X.X.X(浏览本机IP地址)
接着修改nginx主配置文件
systemctl stop nginx
'cd /etc/nginx'
vim nginx.conf

}  

配置文件
cd conf.d
vim vitrual.conf

# configuration of the server
server {
    # the port your site will be served on
    listen 8080;
    # the domain name it will serve for
    server_name  X.X.X.X; # substitute your machine's IP address or FQDN
    error_log /srv/www/yt_demo/logs/error.log;
    access_log /srv/www/yt_demo/logs/access.log;
    charset     utf-8;

    # Django media
    location /media/  {
        alias /srv/www/yt_demo/media/;  # your Django project's media files - amend as required
    }

    location /static/ {
        alias /srv/www/yt_demo/static/; # your Django project's static files - amend as required
    }

    # Finally, send all non-media requests to the Django server.
    location / {
        uwsgi_pass  unix:/opt/uwsgi/sock/yt_demo.sock;
        include    uwsgi_params; # the uwsgi_params file you installed
    }

创建用户组

useradd -s /bin/false -r uwsgi

创建Django项目

进入虚拟环境
source /opt/python-virtual-env/demo/bin/activate
选择路径创建项目
cd srv/
mkdir www
cd www
django admin startproject yt_demo
创建logs目录记录log文件
mkdir logs
cd logs
创建空文件
vim error.log
vim access.log
接下来修改文件权限保证nginx能够拥有访问权限
chown nginx:nginx -R yt_demo/
返回yt_demo文件夹并创建static和media文件夹
mkdir static
mkdir media

配置uwsgi

cd /etc
mkdir uwsgi
cd uwsgi
vim emperor.ini

[uwsgi]
emperor = /etc/uwsgi/vassals
uid = uwsgi
gid = nginx
logto = /etc/uwsgi/log

创建log文件
vim log
vassals配置
mkdir vassals
vim demo.ini

[uwsgi]
http = :8000
socket = /opt/uwsgi/sock/yt_demo.sock
chdir = /srv/www/yt_demo
pythonpath = /srv/www/yt_demo/yt_demo
home = /opt/python-virtual-env/demo
module = yt_demo.wsgi
uid = uwsgi
chmod-socket = 664
chown-socket = uwsgi

修改系统uwsgi配置
cd /etc/systemd/system
vim uwsgi.service

[Unit]
Description=uWSGI Emperor
After=syslog.target

[Service]
ExecStart = /opt/python-virtual-env/demo/bin/uwsgi --ini /etc/uwsgi/emperor.ini
ExecStop = kill -INT `cat /run/uwsgi.pid`
ExecReload = kill -TERM `cat /run/uwsgi.pid`
Restart = always
Type = notify
NotifyAccess = main
PIDFile = /run/uwsgi.pid

[Install]
WantedBy=multi-user.target

创建sock

cd /opt/
mkdir sock
修改访问权限
'chown uwsgi:uwsgi /opt/uwsgi'
接下来测试配置是否成功
systemctl start nginx
systemctl start uwsgi

Django接受文件

创建Django应用

进入yt_demo项目路径
cd /srv/www/yt_demo/
创建应用
python manage.py startapp swim
修改/swim/views.py

from django.views.decorators.csrf import csrf_exempt
from django.core.files.storage import default_storage
from django.core.files.base import ContentFile
import traceback

from . import models

@csrf_exempt
def Uploadfile(request):
    if request.method == 'GET':
        return HttpResponse("Get success")
    elif request.method == 'POST':
        try:
           # newtxt = models.Txt(txtfile = request.FILE['accData'])
           # newtxt.save()
            swim_txt = request.FILES.get('accData')
            #with open('/srv/www/yt_demo/media/acc/acc.txt','wb+') as destination:
             #   for chunk in swim_txt.chunks():
              #      destination.write(chunk)
            path = default_storage.save('/srv/www/yt_demo/media/acc/'+swim_txt.name,ContentFile(swim_txt.read()))
            return HttpResponse('POST success')
        except:
            tb = traceback.format_exc()
            return HttpResponse(tb)
    else:
        return HttpResponse('Other request')
    #if request.method == 'POST':
       # try:
           # swim_txt = request.FILES.get('accData')
           # path = default_storage.save('User/static/User/swimdata/'+swim_txt.name,ContentFile(swim_txt.read()))
       # return HttpResponse('File got')
      # except:
            #return HttpResponse('File failed')

def index(request):
    return HttpResponse("Hello,world.You're at the swim index.")
# Create your views here.

修改swim/urls.py

from django.conf.urls import url
from . import views

urlpatterns = [
    url(r'^$',views.index,name = 'index'),
    url(r'^Uploadfile/$',views.Uploadfile,name = 'Uploadfile'),
]

修改yt_demo/urls.py

from django.conf.urls import url,include
from django.contrib import admin
from django.conf.urls.static import static
from django.conf import settings

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^swim/', include('swim.urls')),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

记得修改media文件夹的访问权限防止出现权限问题
