我如何安装laravel：

通过SSH登录到服务器。 cd /home/username/

// Download composer & install & unistall

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('SHA384', 'composer-setup.php') === '669656bab3166a7aff8a7506b8cb2d1c292f042046c5a994c43155c0be6190fa0355160742ab2e1c88d40d5be660b410') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

// Download laravel

/opt/cpanel/ea-php71/root/usr/bin/php /home/username_here/composer.phar create-project --prefer-dist laravel/laravel

// Create soft link

rm -rf public_html
ln -s laravel/public/ public_html


// Change ownership permissions 

chown -R username_here:username_here /home/username_here/laravel
chown -R username_here:username_here /home/username_here/public_html

// Generate a key 

/opt/cpanel/ea-php71/root/usr/bin/php /home/username_here/laravel/artisan key:generate

服务器使用MultiPHP Manager，所以为了使用php 7.1版，我必须使用所选的php版本（/ opt / cpanel / ea-php71 / root / usr / bin / php）

Answer 1

我是使用旧版PHP 5的Web服务器。要解决它，请尝试

sudo a2dismod php5 sudo a2enmod php7.0 sudo service apache2 restart

Answer 2

解决方案是与我的托管服务提供商联系，并将PHP版本更改为＆gt; = 5.6.4。

Answer 3

您的index.php文件有问题

require __DIR__.'/../bootstrap/autoload.php';

在这一行中，您必须用供应商替换该引导程序，因为laravel 5.6将自动加载文件存储在供应商文件夹中而不是引导程序文件夹中

请删除引导程序并添加供应商，然后运行composer dump-autoload command而不是尝试访问：）

完全安装后，Laravel 5.4会抛出500错误
