 Description   

I am using nginx with 1.12.2 to access ASTPP, but the web browser shows 502 bad gateway. After invetigation, it may relate to nginx buffer config problem.

/etc/nginx/conf.d/cent_astpp.conf

server {
listen 8089 default_server;
listen [::]:8089 default_server;

root /var/www/html/astpp;
client_max_body_size 8M;

  1. Add index.php to the list if you are using PHP
    index index.php index.html index.htm index.nginx-debian.html;

server_name _;
access_log /var/log/nginx/astpp_access.log;
error_log /var/log/nginx/astpp_error.log;

location /

{ try_files $uri $uri/ /index.php; }
  1. pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ { fastcgi_connect_timeout 300; fastcgi_send_timeout 300; fastcgi_read_timeout 300; fastcgi_split_path_info ^(.+\.php)(/.+)$; # fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; fastcgi_buffer_size 128k; fastcgi_buffers 256 4k; fastcgi_busy_buffers_size 256k; fastcgi_temp_file_write_size 256k; }

    }

[root@localhost log]# service php-fpm status

Btw, After I check nginx error log.

This shows

2018/04/15 23:46:24 [error] 16536#0: *1 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 192.168.1.137, server: _, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "10.10.168.103:8089"

Install net-tools and check the response of below command,
netstat -pan|grep 9000
It should be, tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN XXX/php-fpm: master
