Laravel sqlsrv works in tinker mode but not in browser

问题

I have a Laravel 5 project (on a CentOS 7 machine) that connects to an external MSSQL database.

I followed the setup outlined here using FreeTDS.

When I hit the page using a browser I get the error: SQLSTATE[HY000] Unable to connect: Adaptive Server is unavailable or does not exist (severity 9).

But when I use php artisan tinker and do something like App\MyModel::get();, it returns an Illuminate\Database\Eloquent\Collection instance with the records/models just fine.

Anyone knows what's wrong with this?

UPDATE My .env looks like the following:

SQLSRV_DB_DRIVER=sqlsrv
SQLSRV_DB_HOST=host.ip.address
SQLSRV_DB_DATABASE=my_db
SQLSRV_DB_USERNAME=my_username
SQLSRV_DB_PASSWORD=my_password

And my config/database.php looks like:

'sqlsrv' => [
        'driver'   => env('SQLSRV_DB_DRIVER'),
        'host'     => env('SQLSRV_DB_HOST'),
        'database' => env('SQLSRV_DB_DATABASE'),
        'username' => env('SQLSRV_DB_USERNAME'),
        'password' => env('SQLSRV_DB_PASSWORD'),
        'prefix'   => '',
];

My model has a connection specified: protected $connection = 'sqlsrv';

I'm using FreeTDS with unixODBC.

回答1:

SELinux is blocking your outgoing connection to MSSQL.

The proper solution is to allow apache to make the connection:

setsebool -P httpd_can_network_connect_db 1

The -P flag makes the rule persistent, otherwise the rule is lost after a reboot.

It turns out it wasn't a Laravel problem but a SELinux problem. I disabled SELinux by following this guide then I was able to access my project in a browser.

I know this is not the best solution but it works for my purpose.
