AWS RDS 修改 max_connections

You can change the max_connections value by either updating the default parameter policy or create a new one - I'd suggest going with the latter.

• Go to RDS
• Parameter Groups
• Create a new Parameter Group (AWS wil leave everything as default)
• search for the max_connections value
• Change the value to use
• Go to RDS instance and modify
• Select new Parameter group created and restart the instance or let AWS reboot it during next maintenance window
