First time Magento user here, seeking enlightenment. I did a CLI install on CentOS 7 using the following command...

./bin/magento setup:install 
 --db-host="" --db-name="th_magento"
 --db-user="th_magento" --db-password="asdfashd238"
 --admin-firstname="Hugh" --admin-lastname="Mongous"
 --admin-email="humongous@example.com" --admin-user="admin"
 --admin-password="b39fe8a09" --backend-frontname="aaa"

[... ssh buffer too small ...]

[SUCCESS]: Magento installation complete.
[SUCCESS]: Magento Admin URI: /aaa
Nothing to import.

For some reason I can't understand1 all I get when I navigate to /aaa is an Error while establishing database connection message (rough translation, locale is not english).

I tried some basic troubleshooting like checking requirements with the web based install, and ensuring that I can login using the MySQL client and it works. I can't find the logs for the error, tough...

I can post additional data if needed. It might be worth noting the SQL server is MariaDB 10.0 and that the frontend shows no errors (it seems to display correctly).

1: Wouldn't the install stop before the [SUCCESS]: Magento installation complete. if there was a problem?

Update: env.php

The db user and password match...

'db' => [
        'table_prefix' => '',
        'connection' => [
            'default' => [
                'host' => 'localhost',
                'dbname' => 'th_magento',
                'username' => 'th_magento',
                'password' => 'asdfashd238',
                'model' => 'mysql4',
                'engine' => 'innodb',
                'initStatements' => 'SET NAMES utf8;',
                'active' => '1'

While at it I also enabled developer mode, but nothing changed in the error page html. The var/log/debug.log file contains only cache_invalidate entries, while connector.log is empty.

  • add you your app/etc/env.php databse conneciton array code after installation. – Saphal Jha May 21 '19 at 11:57
  • your database is down – MagenX May 21 '19 at 12:02
  • @MagenX how can it be down if the install used the db and CLI mysql login is ok? – beppe9000 May 21 '19 at 12:27
  • @SaphalJha I updated with the env.php's db section – beppe9000 May 21 '19 at 12:27

Please try:

php bin/magento setup:install 
  • 1
    This and replacing all FollowSymlinks directives with SymlinkIfOwnwner match did the trick. – beppe9000 May 22 '19 at 14:48

Try switching from localhost to or vice versa for your database host in the magento configuration. Failing that you might have to put the FQDN to the database server.

  • do i need to drop the tables or just re-run the install command ? – beppe9000 May 21 '19 at 11:52
  • Edit app/etc/env.php on server. If it works and you get connection and redirect you will need to update base urls in db as shown in other answer. – Dominic Xigen May 21 '19 at 11:59
  • Same error with, localhost, and FQDN, I also updated the question... – beppe9000 May 21 '19 at 12:35
