Realization of Configuration Method of Domain Name in Front and Back Ends of nginx

This paper mainly introduces the method of configuring the same domain name at the front and back ends of nginx, and shares it with everyone, as follows:

upstream dfct {
# ip_hash;
 server 121.41.19.236:8192;
}
 
server {
 server_name ct.aeert.com;
 
 location / {
  root /opt/web;
  try_files $uri $uri/ /index.html;
  error_page 405 =200 http://$host$request_uri;
 }
 
 location ^~/web/ {
  proxy_set_header Host $proxy_host;
#  proxy_set_header Host $host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_pass http://121.41.19.236:8192/;
 }
 
 
 listen 443 ssl; # managed by Certbot
 ssl_certificate /etc/letsencrypt/live/ct.aeert.com/fullchain.pem; # managed by Certbot
 ssl_certificate_key /etc/letsencrypt/live/ct.aeert.com/privkey.pem; # managed by Certbot
 include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
 ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
 
}
 
 
server {
 if ($host = ct.aeert.com) {
  return 301 https://$host$request_uri;
 } # managed by Certbot
 
 
 listen 80;
 server_name ct.aeert.com;
 return 404; # managed by Certbot
 
 
}

Add: Three ways to deploy nginx for projects with separate front and back ends

For separate front-end and back-end projects, the front-end and back-end can use different domain names or the same domain name

The following is the case where the front and back ends use the same domain name:

1. www. xxx. com for the front end and api. xxx. com for the back end

server {
server_name www.xxx.com;

location / {
 root /tmp/dist;
 index index.html;
 try_files $uri $uri/ /index.html;
  }
 }

server {
server_name api.xxx.com;
location / {
uwsgi_pass 127.0.0.1:8000;
include /etc/nginx/uwsgi_params;
 }
}

2. The front end uses www. xxx. com, and the back end uses www. xxx. com/api/

1. uwsgi can be matched in this way if http is used

server {
server_name www.xxx.com;

location / {
 root /tmp/dist;
 index index.html;
 try_files $uri $uri/ /index.html;
 }

location ^~ /api/ {
 proxy_pass http://127.0.0.1:8000/;
 }
}

2. If uwsgi is used in socket mode, it needs to be matched like this

server {
server_name www.xxx.com;
location / {
 root /tmp/dist;
 index index.html;
 try_files $uri $uri/ /index.html;
}

location ^~ /api/ {
 proxy_pass http://127.0.0.1:8080/;
 }
}
server {
listen 8080;
location / {
uwsgi_pass 127.0.0.1:8000;
include /etc/nginx/uwsgi_params;
 }
}
