Directadmin for 1000 domains

[mjokiel]

Hello,

I would like to ask you about some tuning case related with Directadmin.
We are using Directadmin on vps which is in fact on one of our machines.
It has for now allocated 2GB RAM, 2 cpu cores.

In near future we are planning to have there around 1000-1500 domains and
350 mysql databases.

Of course when the usage of the resources will be increasing we will be allocating more RAM , dedicated machine has 12GB RAM.

Virtualization is OpenVZ

Could you please advice some info regarding tuning?

Regards,
Mariusz Jokiel

Hi mjokiel

For your information, I am currently hosting the following customers on a Xen-based VPS server with 2GB of memory, without any performance issues whatsoever:

- 183 users (domains)
- 812 email accounts
- 119 databases

I believe I could run the above hosting accounts on a server with even 1GB of memory.

What settings of apache and mysql do you have? Did you tune somehow your vps?

Hi,

You shall tune the httpd-mpm.conf it depends on the amonth of traffic the websites have,

this is an example of my configuration for a site with very high load traffic
(It will not be good for your case but this is good example what you can change for better preformance)


StartServers 100
MinSpareServers 10
MaxSpareServers 15
ServerLimit 250
MaxClients 250
MaxRequestsPerChild 5

You also should decide if to work with KeepAlive or without KeepAlive in the apache. it depends how many free RAM you have.


also i suggest to make sure mysql cache is enable.
