error installing magento

[f3rnand3s]

Amigos, vocês já se depararam com este tipo de erro após instalar o magento 2, estou tentando usar várias versões 2x e o erro persiste.

An error has happened during application run. See exception log for details.

Este erro corre depois que eu faço a instalação por via composer, em seguida essa tela este erro aparece.

Abaixo, tenho as impressões e o registro de erros

Hi there,

The reason for this issue is that your PHP/nginx/Varnish settings are not configured properly to run the Magento installation process.

The installation process requires the following settings:

All web servers and Varnish

1. Locate your php.ini using a phpinfo.php file.
2. As a user with root privileges, open php.ini in a text editor.
3. Locate the max_execution_time setting.
4. Change its value to 18000.
5. Save your changes to php.ini and exit the text editor.

6. Restart Apache:

   • CentOS: service httpd restart
   • Ubuntu: service apache2 restart

   If you use nginx or Varnish, continue with the following sections.

nginx only

If you use nginx, use our included nginx.conf.sample or add a timeout settings in the nginx host configuration file to the location ~ ^/setup/index.php section as follows:

location ~ ^/setup/index.php {
	.....................	fastcgi_read_timeout 600s;   	fastcgi_connect_timeout 600s;
}

Restart nginx: service nginx restart

  Varnish only

If you use Varnish, edit default.vcl and add a timeout limit value to the backend stanza as follows:

backend default {
.....................
      .first_byte_timeout = 600s;
}

Restart Varnish.

	service varnish restart

Those instructions are from the official Magento 2 Developer Documentation:

http://devdocs.magento.com/guides/v2.0/install-gde/trouble/php/tshoot_70pct.html and Magento installation

good afternoon friend. already tried that too was not.
I still don't know if the problem could be SSL

I have another server with the same settings, the same hosting company and I ended up doing an installation test, and it was completed normally.

The only difference is that on this server I'm working on, the domain is not yet pointed to the server and the SSL certificate is not installed yet.

Could that be it?
