Error setting up adminer with NGINX

Asked by Ajit Goel

I have set up MeteorJs application with MongoDB backend. I am trying to set up adminer so I can query MongoDB without opening input ports on my droplet. Everytime I try to reload the nginx settings, I get nginx: [emerg] no port in upstream "php" in /etc/nginx/sites-enabled/admin:32 errors. What am I missing?

/etc/nginx/sites-enabled/admin

server {
    listen         80;
    server_name    165.227.197.220;
    return         301 https://$server_name$request_uri;
}

server {
    server_name    165.227.197.220;
    listen             443 ssl;
    access_log     /var/log/nginx/admin.access.log;
    error_log      /var/log/nginx/admin.error.log;

    ssl_certificate /etc/nginx/ssl/admin.crt;
    ssl_certificate_key /etc/nginx/ssl/admin.key;

    root           /var/www/admin;
    index          adminer.php;

    # Get file here https://codex.wordpress.org/Nginx
    include        global/restrictions.conf;

    auth_basic "Restricted";
    auth_basic_user_file /etc/nginx/.htpasswd/admin;

    location / {
        try_files $uri $uri/ =404;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass php;
        fastcgi_index adminer.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

/etc/nginx/global/restrictions.conf

# Global restrictions configuration file.
# Designed to be included in any server {} block.
location = /favicon.ico {
    log_not_found off;
    access_log off;
}
 
location = /robots.txt {
    allow all;
    log_not_found off;
    access_log off;
}
 
# Deny all attempts to access hidden files such as .htaccess, .htpasswd, .DS_Store (Mac).
# Keep logging the requests to parse later (or to pass to firewall utilities such as fail2ban)
location ~ /\. {
    deny all;
}
 
# Deny access to any files with a .php extension in the uploads directory
# Works in sub-directory installs and also in multisite network
# Keep logging the requests to parse later (or to pass to firewall utilities such as fail2ban)
location ~* /(?:uploads|files)/.*\.php$ {
    deny all;
}

Hello,

You have to change the fastcgi_pass php; part to your actual address of your FastCGI backend. The address can be specified as a TCP socket (IP and Port):

fastcgi_pass 127.0.0.1:9000;

or as a UNIX-domain socket path:

`` fastcgi_pass unix:/tmp/fastcgi.socket


Note that this would depend on your PHP FPM configuration. 

If you have not yet installed and configured PHP-FPM, I would recommend taking a look at stpe 3 here in this article:

Hope that this helps!
Regards,
Bobby

Thank you Bobby, I am able to get the adminer login screen.

Here’s the changes that I made: Installed universe and php-frm, php-mysql

sudo add-apt-repository universe
sudo apt install php-fpm php-mysql

Added the following node to the /etc/nginx/sites-enabled/admin file:

server {
    server_name    <MyDigitalOceanIpAddress>;
    listen         8081;
    root           /var/www/admin;
    index          adminer.php;
    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
    }
    location ~ /\.ht {
        deny all;
    }
}
