Drupal 8.x

Hello

On a VPS with 2 GB ram only, I can install D8.4.0 with Composer

but I cannot install a module !

-------------------------------------------

php -d memory_limit=-1  ../composer.phar require drupal/pathauto -vvv

...

I know just enough to get the job done when it comes to web applications. I setup D6 years ago and created some modules using DHTMLX grid controls, and it was great. Now I'm trying to do some new things, starting fresh with D8. I have the site running, LDAP working, and the basic shell of a custom module working, which just displays some text in the content area with a simple controller.

I want to send an email to the submitter with SMTP as the default method depends on PHP and always ends up in the spam of both my mail and sender mail. I decided to set SMTP as my default. I installed mailsystem and SMTPauth modules. I set SMTP in malisystem and set my SMTP configuration in STMPauth. However, it never sends correctly. I suppose the problem is with some this in drupal as seen in the log report the error starts from within the system.

I remember when I think about drupal 8.2.6 or around there, we have zymphonies travel theme for drupal 8 why now their gone, there is only d7 version now?

Hi everybody,

this is my first post, so please, be patience. 

I'm on my way to learn Drupal, and after I've seen how an entity can be created, I'm trying to figure out the relationship with Content Type. For Example, is it possibile to create Content Type that use a Content Entity as repository. Am I thinking it in the wrong way? 

Thanks in advice.
