如何使用 uwsgi-socket 与 nginx 进行负载平衡

Question

I am using socket file for accessing my application with nginx. my application consist of three server listening on 8080, 8081, 8082. server configuration under /etc/nginx/sites-available/config-file is below

server {
    listen 8080 default_server;
    listen [::]:80 default_server;
    root /var/www/html;
    index index.html index.htm index.nginx-debian.html;
    server_name my-server-one;
    location / {
            include uwsgi_params;
            uwsgi_pass unix:/tmp/server_one.sock;
    }


server {
    listen 8081 default_server;
    listen [::]:80 default_server;
    root /var/www/html;
    index index.html index.htm index.nginx-debian.html;
    server_name my-server-two;
    location / {
            include uwsgi_params;
            uwsgi_pass unix:/tmp/server_two.sock;
    }

server {
    listen 8082 default_server;
    listen [::]:80 default_server;
    root /var/www/html;
    index index.html index.htm index.nginx-debian.html;
    server_name my-server-two;
    location / {
            include uwsgi_params;
            uwsgi_pass unix:/tmp/server_three.sock;
    }

my question is how can i apply load balance with upstream? like below upstream container

upstream myserver {
    server localhost:8080;
    server localhost:8081;
    server localhost:8082;
}

Answer 1

Thanks i found the solution finally and want to share

for setting up nginx load balancer i added the.sock file in upstream and pass the upstream to uwsgi_pass

nginx load balancer with socket

upstream myserver {
   server unix:///tmp/server_one.sock;
   server unix:///tmp/server_two.sock;
   server unix:///tmp/server_three.sock;
}

the /etc.nginx/sites-available/nginx-config files are below

server {
   listen 8080 default_server;
   listen [::]:80 default_server;
   root /var/www/html;
   index index.html index.htm index.nginx-debian.html;
   server_name my-server-one;
   location / {
        include uwsgi_params;
        uwsgi_pass myserver;
}

server {
   listen 8081 default_server;
   listen [::]:80 default_server;
   root /var/www/html;
   index index.html index.htm index.nginx-debian.html;
   server_name my-server-two;
   location / {
        include uwsgi_params;
        uwsgi_pass myserver;
}

server {
   listen 8082 default_server;
   listen [::]:80 default_server;
   root /var/www/html;
   index index.html index.htm index.nginx-debian.html;
   server_name my-server-two;
   location / {
        include uwsgi_params;
        uwsgi_pass myserver;
}
