Magento 2.3 Installation blank page

[marco_santana]

I'm having the same issue here. I think it's caused because some missing conf in my nginx file, but i don't know what's missing. 

here's my nginx.conf file:

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/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  /var/log/nginx/access.log  main;

    sendfile        on;

    keepalive_timeout  65;

    upstream fastcgi_backend {
        # socket
        # server unix:/var/run/php5-fpm.sock;
        server   unix:/var/run/php/php7.1-fpm.sock;
        # use tcp connection
        #  server  127.0.0.1:9000;

    }

    server {
        listen       80;
        
        server_name  localhost;

        set $MAGE_ROOT /var/www/html;
        #set $MAGE_DEBUG_SHOW_ARGS 1;
        
        #set $MAGE_MODE developer;
        #set $MAGE_MODE default;
        #set $MAGE_MODE production;

        location / {
            root   $MAGE_ROOT;
            index  index.php;
            autoindex off;
            charset UTF-8;
            error_page 404 403 = /errors/404.php;
        }

       location ~ \.php$ {
            root           /var/www/html;
            fastcgi_pass   php:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }

    }
}

I'm using php 7.1-fpm and nginx 1.17.3 running on docker containers

I just had this for the first time with a new installation

Thought usual permissions or user groups... Nothing that usually works was working. started panicking

Answer:
Only difference was. I was doing the install on a clean OS install.
Make sure you have all the Magento required PHP extensions installed and enabled.

I know I usually used to go to install wizard and see it tell me my missing extensions and going from there but

if you don't have php7.2-xml extension the installer wont even run
nothing will run. get php xml extension and restart your apache

[finalfantasy1st]

this worked for me!

I run this code: sudo chmod -R 777 /var/www/html/magento

it seems that the problem is about permissions.

[Anoop D]

Is it a safe option to make the installation folder 777 ?

[teddy_kilonzi1]

I have the same issue:

Magento 2.4, PHP 7.4 Nginx.

I have even tried changing permission to the unsafe 777 but nothing seems to work

It's ok after I install php7.2. Thank you!
