Magento2 setup/index.php from console DbConfig not found

Question

I'm trying to install magento2 from console. I use following:

php setup/index.php install
--db_host=localhost
--db_name=magento2ce 
--db_user=root
--db_pass=root
--backend_frontname=admin
--admin_username=admin
--admin_password=q111111
--admin_email=test@domain.com
--admin_firstname=admin
--admin_lastname=admin

And I'm getting following error:

Installing data.. PHP Fatal error:  Class 'Magento\Framework\App\DeploymentConfig\DbConfig' not found in /var/www/m2.dev/www/magento2ee/lib/internal/Magento/Framework/ForeignKey/Config/Reader.php on line 100

I see, that there no such file in the described directory. I have only 2 files in

/lib/internal/Magento/Framework/App/DeploymentConfig/

They are: Reader.php and Writer.php

---

When I execute

php bin/magento setup:install

with any params I'm getting

  [InvalidArgumentException]
  Command "setup:install" is not defined.
  Did you mean this?
      setup:config:set

After installation from console when I run from browser http://magehost/index.php I'm getting following:

Running update doesn't help, I got following error:

Answer 1

I'm not sure the install works like that for later versions.
Try to install it via this command:

php bin/magento setup:install {all your params here}

Answer 2

set the right permissions first then use the installer on the console with the parameters below

find var vendor pub/static pub/media app/etc -type d -exec chmod u+w {} \;
find var vendor pub/static pub/media app/etc -type f -exec chmod u+w {} \;
chmod u+x bin/magento;
bin/magento setup:install\
    --db-host=127.0.0.1\
    --db-name=dbname\
    --db-user=root\
    --db-password=root\
    --backend-frontname=admin\
    --admin-user=admin\
    --admin-password=„password123“\
    --admin-email=yourmail@mail.com\
    --admin-firstname=John\
    --admin-lastname=Doe\
    --use-sample-data\
    --base-url="http://mage.local“\
    --language=en_US\
    --timezone="Europe

omit the param --use-sample-data if you don not want to install sample data

bin/magento setup:upgrade
bin/magento indexer:reindex
bin/magento cache:clean
bin/magento deploy:mode:set
