Can't select database - Wordpress

Question

When I download a new wordpress from wordpress.org and then paste it into my www folder of WAMP, then create a new database in phpmyadmin, then go to localhost and click the

Answer 1

Please don't overcomplicate.

In the "Database Host" field add "localhost: e.g. in my case "localhost:3308" solved the problem.

Answer 2

For me, the solution was giving wp_user all permissions on the wp_db database.

I achieved this using the command line interpreter (CLI):

$ mysql -uroot -p
MariaDB [(none)]> GRANT ALL ON `wp_db`.* TO `wp_user`@`localhost` IDENTIFIED BY 'pass';
MariaDB [(none)]> exit;

After these operations, I restarted the database:

$ systemctl restart mysql

Of course, the database name (wp_db), username (wp_user), and password of the user (pass) can be different.

Answer 3

I had this issue when trying to transfer databases between WAMP server installations.

I tried opening PhpMyAdmin on new PC, then got the port of MySql server (:3308) and added this port into DB_HOST ('localhost:3308'). This worked for me.

Answer 4

For anyone who's still looking for solutions to this problem - please, check again your wp-config.php database credentials again. I had the same problem today and tried to over-complicate the matter by searching for advanced solutions, while I had a space in my DB_NAME field (was supposed to be 'wpdb' and was ' wpdb').

This space completely messed up my connection, I was even close to reinstalling the whole thing and losing all data.

Answer 5

It sounds like either you have not created a database or your wp-config file is not set up correctly. Have you edited wp-config.php file of wordpress and provided correct database name and user credentials. See Famous 5 minute installation of wordpress for details.

Answer 6

For Mariadb hostname should be localhost:3306 and for MySQL localhost:3308.this fixed my error.
