Installing Drupal

Hello, i want to serve Drupal after installing httpd on my os. But after setting the document root and adding my drupal folder to the documentRoot location I am getting an error when i serve the app.  I am getting "Service Unavailable - The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later." 

Any suggestions? Apache seems like a black box... with a lot of configurations. Any insight would be helpful.

Thanks

Hi.

Below is my situation:

Drupal10 + apache

Dev site: local PC + Lando  in which Drupal is installed as myprojectfolder/web/ and myprojectfolder/vendor/

Production site: Allowed structure for websites is mydomainfolder/public_html/ and mydomainfolder/vendor/

So, how to install Drupal to this production site? And after that, how to rsync my dev site and production site?

The issue I had so far is something like below that having 500 error and couldn't open website due to the mismatch of the public folder's name; web and public_html:

On Ubuntu 20.04, I installed Drupal 10 and am setting it up.  However, after some tinkering, I ended up with a white screen whenever I open html://localhost/drupal.  html://localhost shows the Apache welcome page, so I clearly botched something related to Drupal.  I've only been working on it a few days and haven't done much at all.  The latest things I did were:

1. deleting duplicate composer.json and vendor/ in the drupal/ directory and changing /var/www/html/ ownership to "myusername" instead of "www-data", so I can run composer w/o sudo.  Here are the latest commands I ran:

I know it has been asked dozens of time, but after reading previous posts I am still unsure.  I just installed Drupal 10 and everything looks great with the exception of this error in Drupal status:

"Trusted Host Settings
Not enabled
The trusted_host_patterns setting is not configured in settings.php."

I just launched my first blog post at sysopsguide.com/drupal-ha.

If you're wondering how to setup Drupal 10 with high availability in AWS then definitely check it out. This step by step guide details the entire process, with linux commands you can copy and paste as well as screen shots that illustrate what to do in the AWS console.

If you're a Drupal expert then please take a look and let me know if there is anything that can be improved to make the article more accurate or less confusing.

Thanks! 

I'm new to Drupal and have a lot to learn.  I installed Drupal 10.0.9 on Ubuntu 20.04 and would like to use drush. However, after going through a few steps, I am stuck with the following error:

"Root package 'drush/drush' cannot require itself in its composer.json"

Here are the commands I ran in the process:

sudo curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

sudo composer global require drush/drush:dev-master --with-all-dependencies
