Magento CRITICAL Site Down: SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: YES)

Question

I changed the password in Magento admin panel and cleared the cache via the dashboard. Then my website went completely offline, only to display the multiple lines of text with the 2 exceptions mentioned.

It seems as though the database information within env.php might be encrypted because it has an additional array.

env.php file:

'crypt' => 
array ( 
  'key' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxx' (//not real key)

The following is the error log received when trying to access site:

Exception #0 (Zend_Db_Adapter_Exception): SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: YES)

Exception #1 (PDOException): SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: YES)

I'm a non-tech guy with novice experience with web development. Any help would be appreciated!

Answer 1

The error says MySQL credentials are invalid, please check database credentials in app/etc/env.php. If the password is not correct, update the right one. If the password is correct, try the below steps.

1. Run the below commands from the Magento root folder

   rm -rf generated/code/* generated/metadata/*
   php bin/magento ca:fl
   

2. If you are using php-fpm, you need to restart the php-fpm service as well. Please change the below command depends on the PHP version.

   service php7.1-fpm restart
