nginx stream 模块的应用

nginx 作为反向代理服务器，通常以7层网络代理为主 ， 特殊情况下 也可以进行4层网络代理，实现所谓的透传，以下是一个实例

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

stream {
    upstream localhost-443 {
    server 127.0.0.1:{{grafana_web_port}};
    }
    server {
        listen 443  ;
        proxy_pass localhost-443;
    }
}

http {
    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;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

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

    include /etc/nginx/conf.d/*.conf;
    
    upstream platform-t{
         server 127.0.0.1:8443;
    }
    server {
        listen       444 ;
        server_name  _;
        root         /usr/share/nginx/html;
        index index.html index.htm;
        ssl on;
        ssl_certificate  /opt/cert/server.crt; 
        ssl_certificate_key  /opt/cert/server.key;

        # Load configuration files for the default server block.

        location /profile {
           proxy_pass https://platform-t;
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }
