Yes I've tried it.

Getting an Error. After hours of Google - I have no Idea to fix it:

nginx: [emerg] "server" directive is not allowed here in /var/www/vhosts/system/ebikeforums.eu/conf/vhost_nginx.conf:1 nginx: configuration file /etc/nginx/nginx.conf test failed

Heh, and I'm running 1.4 on my local env 😄

I thought hash load balancing has been in nginx for awhile... hm

I must have misconfigured something. But I cannot find out what the problem is. Is anone else experiencing lots of "upstream prematurely closed connection while reading response header from upstream" errors in their nginx log?

Tried tweaking buffers sizes etc but I see no difference. Get the feeling that nodebb is terminating polling clients connections.

Running 0.7.0-dev

@aixnr Thanks u 🙂
It works now

Well.. For the nodebb application himself you could use "forever" .... but when it turned 5x i stopped using forever (@julian posted somewhere that nodebb application can do the forever job himself)

for the database.. well.. dont monitor it YET cz the volume of my transactions is low...

But any service monitor application could do it.. like nagios ...or newrelic

What he says.
Use both!

Finally the pull request is open https://github.com/NodeBB/NodeBB/pull/2527.

I'm out for today guys, hope you get everything. If not just ask, gn8.

@lenovouser Your method works fine for me over https. Thanks for your persistence.

edit: I just had to add in these two lines for socket.io to work.
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";

@a_5mith yep

fuser -k 3000/tcp

seem to fix it so it will kill all to processes using that port

It may do work. But it is not very clean and can lead to serious problems to solve problems of this kind that way.
Just a little advice. No offence. 😉

<stuff>

So I just built a quick VM locally and followed the guides I mentioned above. Did nothing differently except I didn't install php and apache before and start ripping things out. It works flawlessly. I can only imagine at this point its something with my server and I think I may just wipe it and start clean, using nginx only instead of apache.

Thanks for looking at this stuff guys - I appreciate it.

Edit - welp, it works great now. Probably has this whole time. The URL I was using to hit the forums was set to be x.x.132.x, it had to be x.x.135.x. Hey, at least I learned a TON about nodebb and nginx 🙂 I'll take it.

@a_5mith I have it setup on a new DO droplet using the server IP (no domain yet) for both server_name and the base_url - basically replacing localhost referenced in my previous post. Hope that makes sense.

for example:
"base_url": "http://xxx.xxx.xxx.xxx",
server_name xxx.xxx.xxx.xxx;

working url via http://xxx.xxx.xxx.xxx:4567/forum
404 not found for http://xxx.xxx.xxx.xxx/forum

Appreciate all you help.

I figured this out finally...I had nginx v1.2 which is what's in the default debian 7 repo. Had to add a new key and some new sources from here:

Link Preview Image nginx: Linux packages

favicon

(nginx.org)

Now on nginx v1.6.2 and it seems to be running fine. From what I read there was no websocket support in nginx <1.3

@jmj I found that this thread was deleted, I've restored it because I think it will be useful to someone in the future. Hope that's OK with you - and I'm glad you figured it out 🙂

@markkus Sounds good to me. 👍 Hopefully this also solves @helltux's issue too.

Assuming he correctly substitutes his IP in proxy_pass and his domain name in base_url. 😆

@psychobunny yep.. i did the git pull / upgrade stuff before leaving the office... and before creating this thread : /

@EpicIM_Inc Can you run ifconfig on your server? Is the loopback adapter not set up? 😕

hi @Matt-Worthington . Nice to see you here. 🙂
