MySQLi - Too Many Connections Error due to Amazon AWS
All of a sudden this week, my forums have been getting slammed on two different servers from a ton of hits coming in from various IP addresses that all go back to Amazon AWS.
I've increased max_user_connections in MySQL to 10,000 and tried blocking some of the IP ranges but nothing seems to be working.
Is anyone else seeing this in their forums?
Example:
Database error in vBulletin :
mysqli_real_connect(): (HY000/1040): Too many connections
/home/public_html/forums/includes/class_core.php on line 1351
MySQL Error :

Do you have CSF installed on that server? 0 -

It's the most popular firewall for cPanel Powered servers: How to Configure Your Firewall for cPanel Services - cPanel Knowledge Base - cPanel Documentation 0 -
I assume you mean ConfigServer? I'm not sure if I do or not. If it's not automatically installed with cPanel and WHM, then chances are, no, I don't have it installed. I've been blocking the IP ranges via .htaccess 0 -
It's not installed with cPanel, root user needs to install and configure it manually. You'll be happy you did. ;) 0
