Node.js and nginx
This took me some time to figure out, and I didn’t see any detailed posts or bug reports on how to fix this. Nginx doesn’t support HTTP 1.1 on proxy pass, meaning, when you place Node.JS behind a proxy (for load balancing purposes, or you just have multiple endpoints on port 80), websockets will not work properly, since HTTP 1.1 is a core requirement. You’ll know, when you get errors similar to this:

Error during WebSocket handshake: 'Connection' header value is not 'Upgrade'
XMLHttpRequest cannot load ***. Origin *** is not allowed by Access-Control-Allow-Origin. |
I’m running nginx 0.6.8, with nginx 1.0.11. To fix this, you need to upgrade to a later version of nginx (a development version), which supports HTTP 1.1 (albeit, experimentally), and then enable the proxy_http_version 1.1 parameter in your vhost configuration.
I’m doing this on Ubuntu.
First, let’s compile nginx:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
cd /usr/src
wget http://nginx.org/download/nginx-1.1.13.tar.gz
sudo tar xzvf nginx-1.1.13.tar.gz
cd nginx-1.1.13
sudo ./configure --prefix=/etc/nginx --sbin-path=/usr/sbin --with-http_ssl_module
sudo make; sudo make install
/usr/sbin/nginx -V
# Something like this should show:
nginx version: nginx/1.1.13
built by gcc 4.6.1 (Ubuntu/Linaro 4.6.1-9ubuntu3)
TLS SNI support enabled
configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin --with-http_ssl_module |
Next, we setup our vhost:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
server {
listen 80;
server_name node.domain.com;
location / {
proxy_pass http://localhost:8000;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_redirect off;
proxy_http_version 1.1;
}
} |
And now no more errors, and nodejs is working properly. Do note that this is a “bleeding edge” version of nginx, and could come with its own share of issues – so keep an eye out and test thoroughly!
Edit: If you’re still running into some problems, you can enable only xhr-polling/jsonp-polling in your Node.JS/socket.io configuration:
|
1 2 3 4 |
io.set('transports', [
'xhr-polling',
'jsonp-polling'
]); |
Installing Redmine on Ubuntu 11.04 w/nginx and mongrel
This one took me a few hours, but I’ve got my handy-dandy notes. I’m going to assume you’re got nginx installed, whether there are vhosts or not…
I’m also installing to /var/www/redmine
|
1 2 3 4 5 6 7 |
sudo apt-get install mongrel ruby gems
cd /var/www
wget http://rubyforge.org/frs/download.php/75097/redmine-1.2.1.tar.gz
tar xzvf redmine-1.2.1.tar.gz
mv redmine-1.2.1 redmine
sudo chown www-data: redmine -R
sudo chmod 775 redmine -R |
Next, we are going to patch Redmine, to work with Mongrel
|
1 2 3 4 5 |
cd /var/www/redmine/config/initializers/
wget http://www.redmine.org/attachments/6146/rails_6440_patch.rb
wget https://gist.github.com/raw/826692/cb0dcf784c30e6a6d00c631f350de99ab99e389d/mongrel.rb
sudo chmod 775 . -R
sudo chown www-data: -R |
Next, setup the right versions of Rails, etc
|
1 2 3 |
gem install -v=2.3.14 rails
gem install rack -v=1.1.1
gem install rake -v0.8.7 |
Now setup MySQL:
|
1 2 3 4 |
mysql -uroot -p
create user 'redmine'@'localhost' identified by 'password';
grant all privileges on `redmine%` . * to 'redmine'@'localhost';
create database redmine character set utf8; |
And next, we configure and run the installer for Redmine. We are going to edit the database.yml, set it to match your above settings
|
1 2 3 4 5 6 7 |
cd /var/www/redmine/config
mv database.yml.production database.yml
nano database.yml
cd /var/www/redmine
rake generate_session_store
RAILS_ENV=production rake db:migrate
RAILS_ENV=production rake redmine:load_default_data |
Next, we start the server
|
1 |
mongrel_rails start -e production -p 9001 -d |
Next, create the nginx vhost, I created it as /etc/nginx/sites-enabled/redmine
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
server {
listen 80;
server_name YOUR_HOSTNAME_HERE;
root /var/www/redmine/public;
#error_log /var/log/nginx/redmine.log debug;
expires epoch;
location / {
expires epoch;
alias /var/www/redmine/public/;
try_files $uri/index.html $uri.html $uri @mongrel;
}
location @mongrel {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_pass_header Set-Cookie;
proxy_pass http://127.0.0.1:9001;
}
} |
A better way for nginx PHP config
Doing some reconfiguration on my webserver (nginx) to make it easier to administer. My first goal was to get rid of this nastiness:
|
1 2 3 4 5 6 7 8 9 10 |
server {
...
location ~ \.php$ {
include /etc/nginx/conf/fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/path/to/$fastcgi_script_name;
}
} |
It’s too verbose to copy/paste into each virtual host file. Instead, you can just combine the file into the /etc/nginx/conf/fastcgi_params file. I renamed it to php_params, and this is what it’s got:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 |
location ~ \.php(.*)$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param REDIRECT_STATUS 200;
} |
Now I don’t have to change it everywhere. So, instead, now I do:
|
1 2 3 4 5 |
server {
...
# Include the PHP Fast-CGI Params
include /etc/nginx/conf/php_params;
} |
Bam! 6 lines down to one, and much easier to administer. I like, I like.
