how much RAM webmin will consume

[onasre]

Hello

how much RAM webmin will consume, if installed with usermin Model and Apache.

Thx

[webnine]

Webmin takes about 11MB of RAM on a 32 bit system (20-50% more on a 64 bit system.
But it's hard to get Apache working if RAM is below 256MB.

Agreed, from my experience, webmin idles on around 230mb. With Apache/MySQL/FTP etc.. running.

Thanks for the information guys, I just got a $3 VPS from Buzzservers and I'm trying out webmin hope it runs fine on 256MB of RAM

As Sleddog showed, Webmin is pretty light. Can't comment on UserMin but..

I've got WebMin + Apache + MySQL + PHP running in 77 MB.

Two tweaks to reduce memory consumption:

1) If not needed, disable innodb and berkley database by adding the following code to /etc/my.cnf in the [mysqld] section and reboot mysql

skip-innodb
skip-bdb


2) Reduce Apache's memory usage by adding the following to httpd.conf

MaxSpareServers 1
MinSpareServers 1
StartServers 1

These tweaks work OK for the lightly loaded VPS I use them on but YMMV.

uh. mind providing a link all I see is 15 dollars XD My webmin runs under 10mb though and my default mysql apache etc setup is using 300mb ram because I poorly optimized my settings, I was trying to see how bad I could break a vps before I reloaded it.

I am running the same setup (appache and mysql settings are kinda different) but I am still running webmin + apache + mysql + php at around 90mb of ram.

The deal is now over.

a few our our backup servers/file servers run Virtualmin and that clocks in at about 170megs of ram being used.

Oh and just as a option, i no with virtual min i could configure it where i could select certain applications such as mysql to run as either in ram or hd memory (might not have been that one exactly, but there were many options)

Best

I should add to what I posted above...

Webmin (plus Virtualmin for virtual hosting) uses perl. When you're not doing anything in Webmin/Virtualmin the only memory usage is the webmin service (a small server listening for connections).

When you do something in Webmin/Virtualmin you run one or more perl scripts which use additional memory.

AS a test I installed Webmin and Virtualmin on a local box with 128 MB RAM. To simulate a live environment the box was running Apache with PHP, MySQL, Postfix and Dovecot. Apache & MySQL were tuned to use low memory. Memory usage with everything running and the box idle was about 75-85 MB.

Accessing Virtualmin and using some common functions -- like adding a new domain account -- would exhaust physical memory and cause the box to swap. Definitely not what you want.

Then I popped in another 128 mb stick of RAM, bringing the total to 256 MB. After that I could work through all the Webmin/Virtualmin functions without any significant swapping.

I think Webmin/Virtualmin is quite usable on 256 MB ram. BUT you need to ensure Apache & MySQL are restricted in how much memory they use. Running those services with out-of-the-box configurations can easily kill you. If your initial memory usage with all services running is around 100 MB then I think you'll be just fine.
