Wordpress Database no such file or directory error


All of a sudden, (without any config change), my wordpress server is down and displaying the follow error.

Warning: mysqli_real_connect(): (HY000/2002): No such file or directory in /var/www/html/wp-includes/wp-db.php on line 1653

I’ve tried changing to localhost,, adding a port number behind it but it still dosen’t work. Apache2 and mysql has been restarted and shown to be running correctly. The database is also running fine. I can’t seem to find whats wrong.

Hi @elsonDolphin,

So first, let’s leave the Database configuration enviroment in your wp-config.php file at

Everything that I’ve read points this would be solving the issue however it seems in your case it didn’t. In that case can you see if there is any load on your Droplet at the moment? When you go inside and type in top do you see anything out of the ordinary? Or when you type in w while inside the droplet, do you see any load in the load avarage section?

And lastly, what PHP version are you using? The issue might be coming from there as well.
