I follow this guide.

http://devdocs.magento.com/guides/v2.1/install-gde/install/cli/install-cli-install.html

I tried to run web installatin but it always got stucked so now i try this.

when i go to mysql as root

    mysql> show databases;
    +--------------------+
    | Database           |
    +--------------------+
    | information_schema |
    | mysql              |
    | performance_schema |
    | sys                |
    +--------------------+
    4 rows in set (0,00 sec)



there are not any tables for magento.


So i run this command given in the link

    magento setup:install --base-url=http://127.0.0.1/magento2/ \
    --db-host=localhost --db-name=magento --db-user=magento --db-password=magento \
    --admin-firstname=Magento --admin-lastname=User [email protected] \
    --admin-user=admin --admin-password=admin123 --language=en_US \
    --currency=USD --timezone=America/Chicago --use-rewrites=1

but mine cant run `magento` so i use `./magento`


    root@vegan:/var/www/html/magento2/bin# ./magento setup:install --base-url=http://127.0.0.1/magento2/ --db-host=localhost --db-name=magento --db-user=magento --db-password=magento --admin-firstname=Magento --admin-lastname=User [email protected] --admin-user=admin --admin-password=admin123 --language=en_US --currency=USD --timezone=America/Chicago --use-rewrites=1

      [InvalidArgumentException]   
      Parameter validation failed  
                                   


and other green writings

it says in informaton

    --db-user
    
    User name of the Magento database instance owner.
    
    Default is root.



so i use my mysql password and admin name for it. this time it works but another errors

    root@vegan:/var/www/html/magento2/bin# ./magento setup:install --base-url=http://127.0.0.1/magento/ --db-host=localhost --db-name=magentodb --db-user=root --db-password= root --admin-user=admin --admin-password=admin123 --language=en_US --currency=USD --timezone=America/Chicago --cleanup-database help
    
    
                           
      [RuntimeException]   
      Too many arguments.  

SO, i decrease paramters. but again same

    root@vegan:/var/www/html/magento2/bin# ./magento setup:install --base-url=http://127.0.0.1/magento/ --db-host=localhost --db-name=magentodb --db-user=root --db-password= root 
    
    
                           
      [RuntimeException]   
      Too many arguments. 

i can see

http://localhost/magento2/setup/#/landing-install

page here. i think there are no errors. i can run also setup but it stucks at %66 %67. yesterday icompleted this but it was not adding to shoopping card, today i deleted all php 5.6 7.0 in my pc and reinstalle all. BUt now, it cant install..

what can be reason? i downloaded magento from web and extracted to ww/html

directory is

    /var/www/html/magento2/bin

even for this errors

    root@vegan:/var/www/html/magento2/bin# ./magento setup:install admin-user="root"
    
    
                           
      [RuntimeException]   
      Too many arguments.


    by the way i create user and daabase before installation
    
        mysql -u root -p
        CREATE DATABASE magentodb;
        CREATE USER magento@localhost IDENTIFIED BY 'magento';
        GRANT ALL PRIVILEGES on magentodb.* to magento@localhost;
        FLUSH PRIVILEGES;
        exit
        mysql bu
        11-  service apache2 restart
        12-  service mysql restart
