node.js - AWS configuration nginx reverse proxy does not take effect

Question

I just bought an Amazon server. After installing nginx, I want to access the port specified by the server through the domain name to access different services. The Amazon console sets the security rules.

Modify the nginx.conf file and set up a reverse proxy:

#user  nobody;
worker_processes 1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;
events
{
    worker_connections 1024;
}


http
{
    include 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  logs/access.log  main;
    sendfile on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout 65;

    #gzip  on;

    server
    {
        listen 80;
        server_name localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;
        location /
        {
            root html;
            index index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page 500 502 503 504 /50x.html;
        location = /50x.html
        {
            root html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}
        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }

    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;
    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;
    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;
    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;
    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

    include servers/*.conf;
}

Mainly add include servers/*.conf; at the end, add the conf file in the corresponding directory, the name is domainname.com.conf, the file content:

upstream testproject
{
    server localhost:8080;
}

server
{
    listen 80;
    server_name domainname.com;

    # send request back to apache ##
    location / {
        proxy_pass http://testproject;

        #Proxy Settings
        proxy_redirect off;
        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_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
        proxy_max_temp_file_size 0;
        proxy_connect_timeout 90;
        proxy_send_timeout 90;
        proxy_read_timeout 90;
        proxy_buffer_size 4k;
        proxy_buffers 4 32k;
        proxy_busy_buffers_size 64k;
        proxy_temp_file_write_size 64k;
    }
}

After the setting is completed, restart the server:

sudo /path/to/nginx -s reload

Access addressdomainname.comThe page is as follows:

The result is not the expected result. In theory, it should jump to the server with port 8080, but it does not. Can anyone please give me some advice?
In addition, I want to restart directly by killing the process, execute the command netstat -apn | grep 80, enter as follows:

What does it mean? How to find the pid of the process listening on port 80?

Answer 1

You haven’t seen it in any of the serverslisten 8080;

Answer 2

server {
    proxy_pass http://127.0.0.1:8080;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;    
}

Restart the server, not reload
