Describe your issue as much as you can

i am getting this issue while try to open my Wordpress website

Warning: mysqli_real_connect(): (HY000/2002): Connection refused in /opt/bitnami/wordpress/wp-includes/class-wpdb.php on line 1982
Connection refused

Error establishing a database connection
This either means that the username and password information in your wp-config.php file is incorrect or that contact with the database server at 127.0.0.1:3306 could not be established. This could mean your host’s database server is down.

Are you sure you have the correct username and password?
Are you sure you have typed the correct hostname?
Are you sure the database server is running?
If you are unsure what these terms mean you should probably contact your host. If you still need help you can always visit the WordPress support forums.

Hi @Kurt57,

Thanks for using Bitnami. I have checked your bndiagnostic data and I have found a couple of errors. First, the MariaDB database is not running due to the next error:

2024-08-22  8:16:18 0 [ERROR] mariadbd: Can't create/write to file '/tmp/mysql-init' (Errcode: 2 "No such file or directory")
2024-08-22  8:16:18 0 [ERROR] Aborting

It is so weird you can not write into the /tmp folder. Can you run the command below and try to start MariaDB again?

sudo chown 777 /tmp

The other error I have found is that MariaDB is not monitored by Gonit. Did you update anything in its configuration? Apart from this, it looks like there are a few IP addresses performing a lot of requests to your website. We recommend you to check our guide about bots and how to block them in case it is necessary
