如何使用 cronjob 备份 MySQL 数据库 laravel 4.2

Question

我有一个项目laravel 4.2，现在我会每周自动备份数据库。
我找到了脚本，但它不起作用

    public function fire()
    {
        try {
            $this->process = new Process(sprintf(
                'mysqldump -u%s -p%s %s > %s',
                config('database.connections.mysql.username'),
                config('database.connections.mysql.password'),
                config('database.connections.mysql.database'),
                storage_path('backups/backup.sql')
            ));

            $this->info('The backup has been proceed successfully.');
        } catch (ProcessFailedException $exception) {
            $this->error('The backup process has been failed.');
        }
    }

    protected function getArguments()
    {
        return array();
    }

显示错误

PHP Fatal error: Call to undefined function config() in /var/www/html/guitarni_portal/app/commands/BackupDatabase.php on line 25 Error in exception handler: The stream or file "/var/www/html/guitarni_portal/app/storage/logs/laravel.log" could not be opened: failed to open stream: Permission denied in /var/www/html/guitarni_portal/vendor/monolog/monolog/src/Monolog/Handler/StreamHandler.php:107

Answer 1

您使用的太旧 laravel。但是，您仍然可以使用，

Config::get 而不是 config.

应该可以。
