在django框架中，我们一般直接通过python manage.py runserver来启动提供服务，但是如果生产环境此方法不可行，而且容易导致异常退出，于是需要借助uwsgi来作为守护进程。

操作思路：

  • 服务器中安装uwsgi插件
  • 新建uwsgi.ini文件，写入uwsgi需要的参数
  • 安装nginx，并配置uwsgi_pass 127.0.0.1:9496代理转发
  • 启动nginx、uwsgi

安装uwsgi插件

代码语言：javascript复制
pip install uwsgi

新建uwsgi.ini文件，写入uwsgi需要的参数

可直接在代码根目录中创建uwsgi.ini文件，参考如下：

代码语言：javascript复制
[uwsgi]
socket = 127.0.0.1:9496
chdir = /home/dengzhixu/crawl_data
wsgi-file = /home/dengzhixu/crawl_data/yibo_crawl_data/wsgi.py
processes = 4
threads = 2
#stats = 0.0.0.0:9496
buffer-size = 65536
#daemonize = /var/log/uwsgi.log

安装nginx，配置uwsgi_pass转发

安装nginx步骤省略，可直接去lnmp.org下载集成nginx nginx添加vhost配置文件，参考如下

代码语言：javascript复制
server
    {
        listen 9495;
        #listen [::]:;
        server_name crawl.com ;
        index index.html index.htm default.html default.htm;
        root /home/dengzhixu/crawl_data;
        include rewrite/other.conf;

        location / {            
            include  uwsgi_params;
            uwsgi_pass  127.0.0.1:9496;
            uwsgi_param UWSGI_SCRIPT ./yibo_crawl_data/demosite.wsgi;
            uwsgi_param UWSGI_CHDIR /home/dengzhixu/crawl_data;
            index  index.html index.htm;
            client_max_body_size 35m;
         }
         
        location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$
        {
            expires      30d;
        }
        location ~ .*.(js|css)?$
        {
            expires      12h;
        }
        location ~ /.well-known {
            allow all;
        }
        location ~ /.
        {
            deny all;
        }
        access_log  /home/wwwlogs/crawl.com.log;

启动nginx、uwsgi

代码语言：javascript复制
nginx
uwsgi -d --ini /home/dengzhixu/crawl_data/uwsgi.ini

配置systemd自启动

创建一个systemd服务文件/lib/systemd/system/uwsgi.service

代码语言：javascript复制
[Unit]
Description=uWSGI Emperor
#After=syslog.target
After=network.target

[Service]
#PIDFile=/run/uwsgi.pid
ExecStart=/usr/local/bin/uwsgi --ini /home/dengzhixu/crawl_data/uwsgi.ini
#ExecStop=/usr/local/bin/uwsgi --stop $MAINPID
#ExecReload=/usr/local/bin/uwsgi -d --reload $MAINPID
# Requires systemd version 211 or newer
#RuntimeDirectory=uwsgi
Restart=always
KillSignal=SIGQUIT
Type=notify
#Type=forking
StandardError=syslog
NotifyAccess=all

[Install]
WantedBy=multi-user.target

开启自启动，并启动

代码语言：javascript复制
systemctl start uwsgi.service
systemctl enable uwsgi.service
