change mysql user & pass

i have a remote database setup. and my database is connected with my web server through private network.

so i created 2 users with following command

GRANT ALL ON wordpress.* TO 'wordpressuser'@'localhost' IDENTIFIED BY 'password';
GRANT ALL ON wordpress.* TO 'wordpressuser'@'Private_IP' IDENTIFIED BY 'password';

now i need to change password, does the following command is enough to change? or i need to take any extra step to ensure previous access is revoked.

SET PASSWORD FOR 'wordpressuser'@'localhost' = PASSWORD('new-password');
SET PASSWORD FOR 'wordpressuser'@'Private_IP' = PASSWORD('new-password');

Hi @newbie Since it’s WordPress, meaning PHP, it doesn’t have an idle connection kept alive, so every time it shows a page, it actually does a connection to the database and authenticates every time. So that means you’re all good - no reason to restart the database or anything like that. To do a test, you can simply change the MySQL password to something different and WordPress will give you a database error instantly on reload of a page.


That is enough, but this query will give you a warning and if you read it you see that you do not need to use the PASSWPRD function and instead use plain text password, like this:

SET PASSWORD FOR 'wordpressuser'@'Private_IP' = 'new-password';

thank you guy’s

that worked but it would be very nice if i could revoke ALL PRIVILEGES from a single database.
