Hi, I’ve recently installed Discourse on my own VPS. I have only 2 GB of RAM. Is this sufficient to run a forum in production? There have been times where I got a 502 gateway error which maybe due to lack of memory. Sometimes, after installing a plugin, I have to refresh my admin panel several time…

You can easily run Discourse off a VPS with 2GB of RAM. You may want to consider setting up swap if you don’t have that already. Running ./discourse-setup will do this for you.

I did initially setup swap, but if I use swap memory, it slows it down by a lot, so by default, I didn’t want to do that.

Our default configuration should only use swap under pressure, like during web updates. If you host a large community and start experiencing slows response times from the Discourse API you can increase the CPU/RAM of your server and re-run ./discourse-setup so it starts using the augmented resource…

Is this a new community or did you import a large database? How much traffic do you expect? Single thread cpu speed as well as SSD for storage are critical.

I didn’t import any database. This is a fresh forum with 0 posts. The only traffic is me at the moment. However, I do expect traffic that could be up to 1000 users visiting the site a day.

Curious as to why you advocate against using the bitnami image? (assumably @AntiMetaman is referring to their new helm charts here . But also, they’ve got new a new helm chart here

Just FYI, and offering a different perspective @AntiMetaman Although Discourse can run on a VPS with minimal RAM, when you build and rebuild Discourse it will be quite slow compared to building on a machine with more RAM. I personally would not run a “truly” production Discourse app on 2GB of RAM,…

Discourse recommends 1GB as the minimum and I have ran installations this way and it gets slow quick, therefore I would go with 2GB. This first 2GB last a long mile I currently run a community with ~3500 visits/day without Crawlers and some 20-30 posts per day I haven’t seen any issue with the 2GB…

Discourse にはどのくらいの RAM が必要ですか？

ああ、それはやめたほうがいいですね。あるいは、パフォーマンスが悪い理由を彼らに聞いてみてください。
