Magento 2 Setup Error – Troubleshooting Guide

magento2PHP

I am trying to install Magento 2 after finish install all and composer, went to the browser http://url/setup and get error:

<?php
/**

 * See COPYING.txt for license details.
 */

if (PHP_SAPI == 'cli') {
    echo "You cannot run this from the command line." . PHP_EOL .
        "Run \"php bin/magento\" instead." . PHP_EOL;
    exit(1);
}
try {
    require __DIR__ . '/../app/bootstrap.php';
} catch (\Exception $e) {
    echo <<<HTML
<div style="font:12px/1.35em arial, helvetica, sans-serif;">
    <div style="margin:0 0 25px 0; border-bottom:1px solid #ccc;">
        <h3 style="margin:0;font-size:1.7em;font-weight:normal;text-transform:none;text-align:left;color:#2f2f2f;">
        Autoload error</h3>
    </div>
    <p>{$e->getMessage()}</p>
</div>
HTML;
    exit(1);
}

// For Setup Wizard we are using our customized error handler
$handler = new \Magento\Framework\App\ErrorHandler();
set_error_handler([$handler, 'handler']);

\Zend\Mvc\Application::init(require __DIR__ . '/config/application.config.php')->run();

try to run from the command line getting:

PHP Fatal error: Allowed memory size of 2097152 bytes exhausted
(tried to allocate 8192 bytes) in
/var/www/magento2/setup/config/states.extensionManager.config.php on
line 66

I have change the memory_limit = 2048MB in the php.ini under
/etc/php/7.0/apache2 and made restart to the apache

Sounds like you haven't given PHP enough memory. You can check your current memory limit via <?php phpinfo(); ?>

To increase the limit, edit your php.ini file and find the memory_limit, or create it if you can't find it. Set it to something like memory_limit = 2048M, depending on your available resources. Magento is very memory intensive.
