测试环境：linux centos7下
1、安装uwsgi
python3下安装：
pip3 install uwsgi
python2下安装：
pip install uwsgi
如果是系统自带的python2.7环境下安装的话，有可能会出错：
Command "/usr/bin/python2 -u -c "import setuptools, tokenize;__file__=‘/tmp/pip-build-
jjOBXy/uwsgi/setup.py‘;f=getattr(tokenize, ‘open‘, open)(__file__);code=f.read().replace(‘\r\n‘, ‘\n‘);f.close();exec(compile(code, __file__, ‘exec‘))" install --record /tmp/pip-3cX7u0-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-jjOBXy/uwsgi/
这时候需要我们先安装一个python开发包：
yum install -y python-devel
然后就可以安装了
2、测试 uwsgi
#python 3.x def application(env, start_response): start_response(‘200 OK‘, [(‘Content-Type‘,‘text/html‘)]) return [b"Hello World"] #Python 3.x 需要 返回字节字符串 #python 2.x #def application(env, start_response): # start_response(‘200 OK‘, [(‘Content-Type‘,‘text/html‘)]) # return ["Hello World"]
运行：
uwsgi --http :8000 --wsgi-file test.py
3、添加并发和监控
并发：
uWSGI 默认启动一个单独的进程和一个单独的线程
我们可以通过 --processes 选项或者 --threads (或者两个选项都使用)来增加更多的进程或者线程
uwsgi --http :8000 --wsgi-file test.py --master --processes 4 --threads 2
将会产生 4 个进程(每个进程 2 个线程)，一个主进程(当你的进程死掉时会重新 spawn 一个新的)以及 HTTP 路由器
监控：
知道发生了什么在生产环境中是极其重要的。stats 子系统允许你 用 JSON 输出 uWSGI 的内部数据：
uwsgi --http :8000 --wsgi-file test.py --master --processes 4 --threads 2 --stats 127.0.0.1:8181
用 “uwsgitop”监控应用实例
pip isntall uwsgitop
uwsgitop--uwsgi服务器性能查看工具，用法:
uwsgitop 127.0.0.1:8181
3、连接Django和uwsgi
先测试Django项目本身是可运行的：
python manage.py runserver 0.0.0.0:8001
倘若django 项目没问题，我们就可以把uwsgi与Django连接起来
进入到django项目中，以uwsgi启动django
uwsgi --http :8001 --module WebSite.wsgi
4、编写uwsgi配置文件
[uwsgi] http = :9000 #the local unix socket file than commnuincate to Nginx socket = 127.0.0.1:8001 # the base directory (full path) chdir = /root/workplace/WebSite # Django‘s wsgi file wsgi-file = WebSite/wsgi.py #env virtualenv=/root/.. #可以执行指定虚拟环境 # maximum number of worker processes processes = 4 #thread numbers startched in each worker process threads = 2 #monitor uwsgi status stats = 127.0.0.1:9191 # clear environment on exit vacuum = true
然后放到django项目中
启动uwsgi：
uwsgi --ini path/to/project/uwsgi.ini
然后成功访问到我们的django项目
39.108.132.2xx:9000
5、安装Nginx
yum -y install nginx
启动Nginx
systemctl start nginx.service
关闭Nginx
systemctl stop nginx.service
重启
systemctl restart nginx.service
设置开机启动
systemctl enable nginx
查看nginx 启动状态
systemctl status nginx
查看是否监听
ss -tnl | grep 80
nginx配置
方法一：直接修改nginx.conf：
server { listen 80 default_server; listen [::]:80 default_server; server_name _; root /usr/share/nginx/html; # Load configuration files for the default server block. include /etc/nginx/default.d/*.conf; location / { include uwsgi_params; uwsgi_pass 127.0.0.1:8001; #要跟uwsgi中的绑定的socket一致 } error_page 404 /404.html; location = /40x.html { } error_page 500 502 503 504 /50x.html; location = /50x.html { } }
方法二：添加站点配置
在项目中添加website_nginx.conf
#website_nginx.conf #the upstream component nginx needs to connect to upstream django { # server unix:///path/to/your/mysite/mysite.sock; # for a file socket server 127.0.0.1:8001; # for a web port socket (we‘ll use this first)所有获得的请求都会转到8001端口,也就是uwsgi邦定的socket端口 } # configuration of the server server { # the port your site will be served on listen 9000; # the domain name it will serve for server_name .example.com; # substitute your machine‘s IP address or FQDN charset utf-8; # max upload size client_max_body_size 75M; # adjust to taste # Django media location /media { alias /path/to/your/mysite/media; # your Django project‘s media files - amend as required } location /static { alias /root/workplace/WebSite/static; # your Django project‘s static files - amend as required } # Finally, send all non-media requests to the Django server. location / { uwsgi_pass 127.0.0.1:8001; #跟uwsgi绑定的socket一样 include /root/workplace/WebSite/uwsgi_params; # the uwsgi_params file you installed } }
然后将站点配置软链接到 /etc/nginx/conf.d 目录下
ln -s /root/workplace/WebSite/website_nginx.conf /etc/nginx/conf.d/website_nginx.conf
最后：
copy /etc/nginx下的uwsgi_params 文件 到项目中
重启nginx
启动uwsgi.ini
