How to check the nginx run the same version of php version on Ubuntu?

Question

I just install PHP on the Ubuntu server in the Digitalocean and create a simple PHP file just for testing called phpinfo.php and the contains is:

<?php phpinfo();

When I visit the file I got this error:

I got this error: 502 Bad Gateway nginx/1.18.0 (Ubuntu)

I check the errors in nginx's error log and got this one:

2020/10/01 00:16:26 [crit] 23593#23593: *15 connect() to unix:/var/run/php/php7.2-fpm.sock failed (2: No such file or directory)
while connecting to upstream, client: 212.###.###.182, server: 46.#####.106, request: "GET /info.php HTTP/1.1", upstream: 
"fastcgi://unix:/var/run/php/php7.2-fpm.sock:", host: "46..###.###106"

check php version is :

PHP 7.4.10 (cli) (built: Sep  9 2020 06:36:30) ( NTS )

What is the problem ?

how can I check if Nginx using the same version of PHP 7.4

Answer 1

You have to check php7.*-fpm.sock if it's 4 or 2

First, run this command

sudo vim /etc/nginx/sites-available/YOUR.DOMAIN.COM

you will get something like this:

server {
    listen 80;
    root /var/www/html;
    index index.php index.html index.htm index.nginx-debian.html;
    server_name XXXXXXXXXX;

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

    location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
    }

    location ~ /\.ht {
            deny all;
    }
}

Change the version of PHP to 7.4

fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;

Save file

Then restart Nginx:

sudo service nginx restart

Now visit your app with the name of the file and you will get the PHP page version
