Question

服务器：MySQL5.7，Django2.1，uWSGI，Nginx 我正在处理Django项目，我在一个服务器上部署了Project，在另一台服务器上放置了MySQL。当我使用django admin更改或添加某些项目时，它非常慢，有时无法获取“更改”页面（Nginx给了我504页），有时无法获取自动完成列表（chrome开发者视图给出了我是504错误）。

我尝试了3种改进方法。第一个是将两台服务器的Mbps从1 Mbps更改为5 Mbps，这在某些页面上有所帮助。但是并没有解决所有问题。第二个是更改uWSGI配置，将buffer-size添加为32768。我不确定它是否有帮助，感觉没有帮助。第三个是更改NGINX配置，我尝试将“ fastcgi_connect_timeout 300”添加到conf文件中，不起作用。我测试了使用django runserver和使用uwsgi来运行我的项目，它也很慢（〜50s），但是没有504超时错误，所以我认为NGINX配置可能有问题，但是我不知道如何改变。

我的uWSGI.ini代码：

[uwsgi]
socket = 127.0.0.1:9002
chdir = /home/user/project
wsgi-file = project/wsgi.py
master = true
processes = 4
threads = 2
static-map = /static=static
vacuum = true
daemonize = /home/flwang/oncoview/uwsgi.log
py-autoreload = 1
buffer-size 32768 #This is new

我的project_nginx.config代码：

    upstream django {
        server 127.0.0.1:8000;
    }
server {
    listen 80 default_server;
    listen [::]:80 default_server;

    index index.html index.htm index.nginx-debian.html;

    access_log      /home/user/project/nginx_access.log;
    error_log       /home/user/project/nginx_error.log;

    server_name _;

    location /static/ {
        alias /home/user/project/static/;
    }
location / {
    root /home/user/project; 
    uwsgi_pass django;
    include /home/user/project/uwsgi_params;
}

}

NGINX.config代码：

'''
user  user;
worker_processes  1;
error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

'''

期望很简单，至少可以像使用uWSGI一样更改并使其快速。感谢大伙们。还有中国春节，新年快乐！

出现“ 504超时”错误时，如何改进或修改代码？
