title: running etherpad-lite on nginx
date: 27.09.2011 21:24

As you should already know if you read this blog, I am using [nginx][] as my main http server as well as a reverse proxy for my apps running on node.js or simple ruby.
I'm also running an [etherpad-lite][etherpad] server on [pad.fnordig.de](https://pad.fnordig.de/).
Today [@dasjan][] asked me how I configured my server for this setup:
> @badboy_ Sehe gerade du hast dein etherpad-lite hinter nginx.
> Hast du etwas spezielles konfiguriert?
> ([tweet](https://twitter.com/dasjan/status/118688611980943360))
> _translated_: @badboy_ I saw that you run your etherpad-lite behind a nginx.
> Did you configure anything special?
and
> @badboy_ Bekomme hier nach ein paar Stunden immer Connection Probleme wenn etherpad-lite hinter nginx läuft/
> _translated_: @badboy_ I always get connection problems after some hours when running behind nginx
> ([tweet](https://twitter.com/dasjan/status/118689122452897793))
Even though I did nothing special I post my config here, so maybe this will help.
I currently use nginx [v1.0.6](http://nginx.org/download/nginx-1.0.6.tar.gz)
and
etherpad-lite at [7e4bba0e](https://github.com/Pita/etherpad-lite/commit/7e4bba0e31d600a5d1d3833211252b1472f07f2c) with the default config (and node.js v0.4.8)
etherpad runs as an own user named `etherpad` and is monitored by monit.
The monitoring is as simple as that, `/etc/monit/apps/etherpad.monit`:
check process etherpad
with pidfile /var/run/etherpad-lite.pid
start program = "/home/etherpad/etherpad-lite/daemon.sh start"
stop program = "/home/etherpad/etherpad-lite/daemon.sh stop"
if totalmem is greater than 300 MB for 10 cycles then restart # eating up memory?
{:lang="text"}
And the nginx is nothing fancy at all, `/usr/local/nginx/conf/vhosts/pad.fnordig.de.conf`:
server {
listen 80;
listen [::]:80;
listen 443 ssl;
ssl_certificate /var/certs/star_fnordig_signed.pem;
ssl_certificate_key /var/certs/star_fnordig_signed.pem;
server_name pad.fnordig.de;
access_log /home/etherpad/etherpad-lite-log/eplite.access.log;
error_log /home/etherpad/etherpad-lite-log/eplite.error.log;
location / {
proxy_pass http://localhost:9001/;
proxy_set_header Host $host;
proxy_buffering off;
}
}
{:lang="text"}
My etherpad is currently running for about 22 days without any problems. I don't really use it myself and have no current statistics on outside usage of [pad.fnordig.de](https://pad.fnordig.de/).
Now that [@dasjan][] has mentioned problems on his side I will optimize my monitoring and see if it really runs as smooth as I think.
