Access denied for user 'roundcube'@'localhost' (using password: YES) in /var/www/html/roundcube/program/lib/Roundcube/rcube_db.php on line 177 (GET /roundcube/)

Running Centos 8  with upgraded PHP (7.4.19)


I'm at a loss ....The roundcube user has .... in mysqld

///// GRANT ALL PRIVILEGES ON `roundcube` . * TO 'roundcube'@'localhost'; //////

so why the error?


PS.

I got lazy & copied the config file from a working FC34 config & put it into the Centos8.

The "installer" detected it & said  ...................."OK, lazy people can download the updated config file here: config.inc.php"

HOW ABOUT THAT!!!!!!!

Did you run

Code Select Expand

FLUSH PRIVILEGES; after you ran the MySQL grant command?

[roger2]

yes .....the script did that..... as per

USE mysql;
CREATE USER 'roundcube'@'localhost' IDENTIFIED BY 'mypassword';
GRANT USAGE ON * . * TO 'roundcube'@'localhost' IDENTIFIED BY 'mypassword';
CREATE DATABASE IF NOT EXISTS `roundcube`;
GRANT ALL PRIVILEGES ON `roundcube` . * TO 'roundcube'@'localhost';
FLUSH PRIVILEGES;

i think the problem  needs to focus on LINE 177   (                'line' => __LINE__, 'file' => __FILE__,  )

/var/www/html/roundcube/program/lib/Roundcube/rcube_db.php on line 177 (GET /roundcube/)

# sed -n '177p'   /var/www/html/roundcube/program/lib/Roundcube/rcube_db.php

                'line' => __LINE__, 'file' => __FILE__,
