Mysql and lamp issue: Warning: mysqli_real_connect(): (HY000/2002)
Hi guys, I hope you can help me, since 3 days ago I've been having issues with my droplet with ubuntu 16.04 and lamp. I use my droplet to run a wordpress site and a crm, both uses mysql, but now the server keeps displaying errors like:
Warning: mysqlirealconnect(): (HY000/2002): No such file or directory in /var/www/html/wp-includes/wp-db.php on line 1538
I tried uninstalling completely mysql 5.7 and resinstalling it, restoring a wp db backup, this worked for like an hour, the site displayed fine but then the error displays again.
