Web Served 8: Node.js, Redis, and real-time writing with Etherpad Lite

Aurich · Jun 29, 2013

Etherpad is super useful. The only real weakness is there's no directory structure, I keep a pad just to track our pads. There's also no easy way to nuke a pad, and since the history is always embedded in it that could be awkward if the wrong person is invited to it and can scrub back.

Awesome stuff.
Clear and to the point instructions are rare these days.

Sad to see the series wrapping up

One thing I found: Etherpad's use of port 9001 appears to conflict with Tor.

Also, the rewrite line needs a space between "rewrite" and "^".

Thanks! Fixed. Always hard to ferret out all the typos in a piece with this many code snippets and extra formatting bits.

Looks like you're right about the potential conflict. You can change the port Etherpad runs on by editing the "port" setting at the top of "settings.json". I don't think I'll update the piece, though—I figure most folks savvy enough to be running Tor probably can figure it out.

I have really, really enjoyed this series. It has been a really great jumping off point in creating my own personal website that holds notes and other things that I can host on my own machine without relying on outside cloud services.

Etherpad lite seems like a neat tool. I've never used it but I could definitely see the benefits. I do hope that you continue with intermittent tutorials on webhosting. In particular, I think it would be really cool to see a tutorial on setting up a dropbox alternative (such as owncloud) to really extend the functionality of a home server.

nineplymaple · Jun 29, 2013

I love this series! It has allowed me (a total n00b) to set up my own web server. I really think you should keep it going, maybe setting up Django, considering how beginner-friendly python is.

zeb600 · Jun 30, 2013

Thanks for a great series, Lee - you had a good run there. Personally I would have loved a primer on setting up postgres + ruby too, but I guess people should be able to figure that out on their own after completing the previous entries. Thumbs up!

Let's see if I can get Yii + Postgres up and running on that thing.

If you really want the Wave experience you could try the original (or at least the open sourced version), which is incubating at Apache.

(Personally I found Wave confusing, but it is available)

johnyma22 · Jun 30, 2013

@autodefenestrator You can change the port of Etherpad by Hitting up /admin/settings or by editing settings.json

@Aurich Lawson you can use the API or a plugin to see pads available and to delete existing pads.

Visit /admin/plugins to see the available plugins and one click install them

To get to the /admin/plugins page you need to set a username/pass in settings.json, it'd be great if Lee can do a quick write up about how to install plugins on Etherpad and maybe an authors pick of his favorites!

_bk201 · Jun 30, 2013

Typo in the first set of instructions:

sudo add-apt-repository ppa:chris-lea/node.js ppa:chris-lea/redis-server
sudo add-apt-repository ppa:chris-lea/redis-server

Can only add one ppa at a time.

Fixed! Thanks

Having tried out Etherpad about a year ago, we settled on Gobby, using a infinote server running on an Ubuntu install locally. The latest infinote server is rock solid (been running since November without a single outage)

And Gobby is, in my opinion, far superior, so long as you do not need document history. It has built in chat, full document support (folders, many documents), security communication, great performance, and so on. Etherpad felt very clunky, even when on a local network.

Gobby has replaced instant messaging and chatrooms for our development team. We have documents of the issues and talk right on the ticket itself, which allows for many simultaneous discussions, rather than the 1-2 you can have going in a chatroom.

Thanks for the article!

I've currently got Subethaedit constantly running on my Mac server. I love 'collaborative note-taking' for brainstorming; sometimes I prefer it to face-to-face meetings, depending on the level of detail and time limitations.

When I get to the npm install redis step, I get a series of errors (starting with something along the lines of 'ueberDB is not a valid file name') and the ueberDB redis connector fails to install correctly in the /ueberDB directory.

I got around this by installing the redis connector elsewhere then moving it to the correct directory, as follows:

cd /usr/share/nginx
npm install redis
mv /node_modules/redis /usr/share/nginx/etherpad-lite/src/node_modules/ueberDB/node_modules/
rm -rf node_modules

(be careful with that last command - if you install the redis connector in a directory other than /usr/share/nginx, and that directory already had a 'node_modules' sub-directory, then skip the last command or you'll delete whatever else was already in the sub-directory)

I'm not sure why this was workaround was necessary though. There was already a node-redis module in ueberDB/node_modules, so maybe etherpad/node have preinstalled a different connector and don't want you to use the other redis connector? Any ideas?

Collie147 · Aug 2, 2013

Again, Lee, fantastic series! Learning a lot here. Thanks again.

Having a wee bit of a problem and I've been trying to sort this out all week, but I'm a bit stuck at one part.

Etherpad works fine when I get it running through the server and port 9001 (e.g. http://192.168.1.2:9001) but when I load it through /etherpad/ it appears that the css isn't loading ("New Pad" icon not showing up and format is all over the place on the pad page) and when I create or open an pad I get a flash of an error about not having permission to access something and then " 'require' is undefined in http://192.168.1.2/etherpad/p/Test (line 540)" and can't do anything.

Checked nginx access and error logs, unfortunately the error logs don't point to anything, and the access logs give me a 301 error on the css and javascript files

Think I've found the problem.

"get /wiki/Main_Page HTTP/1.1" 200 5079 "http://192.168.1.2/etherpad/p/Test"
It wouldnt be the line from the wiki.conf file would it?

location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
try_files $uri /wiki/index.php;
expires max;
log_not_found off;
}

Collie147 · Aug 6, 2013

change it to
"location ~* /wiki/\*.(js|css|png|jpg|jpeg|gif|ico)$" and it seems to have worked.

l8gravely · Oct 10, 2013

Nice article, does a good job of explaining *why* you made various choices during the install, which I like. But a quick comment about the SSI of the text file and the cronjob. Wouldn't it be more efficient to just have nginx call the script when someone hits the page, and to cache the result for 60 seconds or so?

This way, you're not endlessly re-writing the output file, and you only put in updates when someone actually hits the etherpad web page. No sense doing work all night from 1am to 6am if no one is actually using the system, is there?

I had the exact same behavior on my installation. I tried your changes and it appears to be working now. Still, I'm at a loss on 'why' would a wiki location have any effect on the pad's css... Let me know the reason if you have the time, and thanks a million for posting it...

To make the pad links work per your instruction, change this:

redis-cli keys 'pad:*' |grep -Eo '^pad:[^:]+' |sed -e 's/pad://'
|sort |uniq -c |sort -rn |awk '{if ($1!="2") {print $2 }}'
|sed -e 's/.*/<a href="\/p\/&">&<\/a>/' -e 's/^/<li>/' -e 's/$/<\/li>/'
> "$PADPATH"

to this:

redis-cli keys 'pad:*' |grep -Eo '^pad:[^:]+' |sed -e 's/pad://'
|sort |uniq -c |sort -rn |awk '{if ($1!="2") {print $2 }}'
|sed -e 's/.*/<a href="\/etherpad\/p\/&">&<\/a>/' -e 's/^/<li>/' -e 's/$/<\/li>/'
> "$PADPATH"

in the getpads.sh file (if your site uses http:/yoursite/etherpad/p/yourpads )

Hello all,

"location ~* /wiki/\*.(js|css|png|jpg|jpeg|gif|ico)$" and it seems to have worked.

I had the exact same behavior on my installation. I tried your changes and it appears to be working now. Still, I'm at a loss on 'why' would a wiki location have any effect on the pad's css... Let me know the reason if you have the time, and thanks a million for posting it...

I'm also in the same boat. I'm able to fix up etherpad with this fix but then the wiki loses images. Thanks for the fantastic series by the way. Had it saved a long time ago and recently had some time and came across my old links.

I was able to fix the issues with the wiki by adding this above the previous fix for etherpad.

location ~* /wiki/skins/common {
try_files $uri /wiki/index.php;
}

Hi Lee,

On this post you show how to setup a location for etherpad as follows:

location /etherpad {
rewrite /etherpad/(.*) /$1 break;
rewrite ^/etherpad$ /etherpad/ permanent;
proxy_pass http://localhost:9001/;
proxy_redirect / /etherpad/;
proxy_set_header Host $host;
proxy_buffering off;
}

This triggered an idea I've been wondering about for a few days, but haven't found the right steps of instructions to come up with a viable solution.

How would you set up nginx as a reverse proxy for an apache web server I'm running on a Mac Mini Server as well as a web server for all the applications you've covered here? Do I need two instances of nginx or just a new location with the proxy_pass command? I'm at an impasse with the basic concept and the specific commands. Thanks.

Zach,

I'm having this same issue. Did you ever get it resolved?

f0fca2l]Hello all,

I am again having a weird issue that pops up a 502 Bad Gateway when trying to access and run etherpad. Fortunately for me it's only affected etherpad and not the entire site this time. Here's a run of my /etc/nginx/sites-available/www file

Code:
