Virtualmin 256Mb

sergiodelatorre

I've tried to install Virtualmin on a 256Mb VPS but it seems that the installation fails when memory is depleted by freshclam database update.

I've installed Virtualmin 2 years ago and I haven't this problem (Virtualmin base installs via script, and then you can complete via web). Is there any form to avoid spamassassin/clamav or install step by step?

Thanks

I use Virtualmin exclusively to host my sites. Regardless of what the instructions say, I've never had any success setting it up on a VPS with less than 512MB. While once you get Virtualmin installed, it will run on less than 256MB. You can't get it installed with less 512MB now. Even with 512MB it can be a stretch. I buy nothing but 1GB VPS for this reason

Yes...you are right @MTUser2012.

It needs about 512 MB during installation. Then, after that, the RAM can be reduced. Similar to installing Windows Server 2012 on a 512 MB machine.

Maybe you can add a lot of swap for the install and remove it afterwards.

all you need is 64mb for Virtualmin full installation.

This page should include plenty of tips and tricks to make this work: https://www.virtualmin.com/documentation/system/low-memory.

I have to admit though, it will be a challenge depending on what kind of traffic you are going to get and what kind of sites you are going to run. For a low memory configuration I'd also try to install NGINX for Virtualmin and get rid of Apache.

Installed multiple times on 256 MB (OpenVZ) boxes, using @mpkossen's great tutorial:

https://lowendbox.com/blog/your-own-mail-server-with-virtualmin/

Running my MX with ~10 domains and ~50 mailboxes, all under 150 MB RAM. This is with ClamAV and all anti-spam stuff turned off, of course. Using text file option instead of MySQL overkill.

This said, I've since moved on to 512 MB KVM's… what can I say… I like having power to spare under the hood

Next step: planning on automating this with Ansible and Virtualmin's command line API, as opposed to manual config using the web UI post install.

You've inspired me to do a new version of that tutorial (maybe even a bit more extensive). Added to my list for WHS!

I've used this tutorial 2 years ago, but now I suppose the ClamAV virus database is bigger and the installation script crashes with 256Mb

I would try with swap as @neps said

Looking forward to this

Interesting. I'm in need of another MX… was planning on firing up another 512MB MX to try out Virtualmin's command line API this weekend. I'll start with a test run on a 256 MB KVM first and report back.
