Ubuntu 16.04, nginx, phpmyadmin - 502 Bad Gateway - php

Question

I am using this setting for nginx (default file):
server {
listen 30425;
# Don't want to log accesses.
#access_log /dev/null main;
access_log /var/log/nginx/php.acces_log main;
error_log /var/log/nginx/php.error_log info;
root /usr/share/phpmyadmin;
index index.php index.html index.htm;
error_page 401 403 404 /404.php;
location ~ .*.php$ {
include fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param SERVER_NAME $http_host;
fastcgi_ignore_client_abort on;
}
}
When I try to access 30425, I am getting 502 Bad Gateway. All other setting are default one (PHP 7).

Answer 1

I had to replace this fastcgi_pass 127.0.0.1:9000;
to fastcgi_pass unix:/var/run/php/php7.3-fpm.sock;
and then it worked perfectly.
Full code.
server{
listen 80;
index index.html index.htm index.php;
server_name 127.0.0.1;
root /usr/share/phpmyadmin;
location / {
#try_files $uri $uri/ = 404;
autoindex on;
}
location ~\.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+);
try_files $uri $uri/ =404;
fastcgi_pass unix:/var/run/php/php7.3-fpm.sock;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_na$
fastcgi_param SERVER_NAME $http_host;
fastcgi_ignore_client_abort on;
}
}
