plain text/index/debug¶

https://www.nginx.com/resources/wiki/start/topics/examples/full/

worker_processes  5;  ## Default: 1

location /code/ {
    location ~* { # All files in it
        add_header Content-Type text/plain;                      # Display file as text
    }
}

location /sub_dir {
    autoindex on;                                                # list dir files
    autoindex_exact_size off;
    charset utf-8;
    root /root_path

    error_log /var/logs/nginx/debug.log debug;                   #   Debug
    # debug, info, notice, warn, error, crit, alert, or emerg
}

Forward Proxy¶

https://www.alibabacloud.com/blog/how-to-use-nginx-as-an-https-forward-proxy-server_595799

server {
    listen  443;

    # dns resolver used by forward proxying
    resolver  114.114.114.114;

    # forward proxy for CONNECT request
    proxy_connect;
    proxy_connect_allow            443;
    proxy_connect_connect_timeout  10s;
    proxy_connect_read_timeout     10s;
    proxy_connect_send_timeout     10s;

    # forward proxy for non-CONNECT request
    location / {
        proxy_pass http://$host;
        proxy_set_header Host $host;
    }
}

Reverse Proxy¶

http://nginx.org/en/docs/http/ngx_http_upstream_hc_module.html

upstream backend {
    server backend1.example.com       weight=5; # by default 1
    server backend2.example.com:8080;
    server unix:/tmp/backend3;

    server backup1.example.com:8080   backup;
    server backup2.example.com:8080   backup;
}

server {
    location / {
        proxy_pass http://backend;  # same name of upstream
    }
}
