在宅基地安装php 7后出现PDO连接错误

Question

我使用本指南https://www.digitalocean.com/community/tutorials/how-to-upgrade-to-php-7-on-ubuntu-14-04升级到宅基地的php 7。但现在我正在尝试在我的laravel应用程序中运行迁移和其他数据库内容，它说：

我已经尝试了sudo apt-get install php7.0-mysql并安装得很好。我也重新加载了nginx和php。

phpinfo也很好。我猜。

laravel中的Mysql配置

'mysql' => [
            'driver'    => 'mysql',
            'host'      => env('DB_HOST', 'localhost'),
            'port'      => env('DB_PORT', 3306),
            'database'  => env('DB_DATABASE', 'forge'),
            'username'  => env('DB_USERNAME', 'forge'),
            'password'  => env('DB_PASSWORD', ''),
            'port'      => env('DB_PORT', 3306),
            'charset'   => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix'    => '',
            'strict'    => false,
        ],

Nginx文件：

access_log off;
error_log  /var/log/nginx/tenant-testing.app-error.log error;

sendfile off;

client_max_body_size 100m;

location ~ \.php$ {
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
    fastcgi_index index.php;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_intercept_errors off;
    fastcgi_buffer_size 16k;
    fastcgi_buffers 4 16k;
    fastcgi_connect_timeout 300;

    fastcgi_read_timeout 300;
}

location ~ /\.ht {
    deny all;
}

ssl_certificate     /etc/nginx/ssl/tenant-testing.app.crt;
