If you are using Ubuntu Hardy then you could try using Brightbox's
repo instead of building your own deb.
If you are however running some other distro then the following (non-definitive) instructions are for you.
Warning: it may be safer to install nginx + passenger via the passenger-install-nginx-module script as it will match passenger with a tested version of nginx.The instructions below simply add passenger support to the latest nginx deb in your distro of choice.
Install passenger gemThe first step is to install the
Phusion Passenger gem:
$ sudo gem install -V -r passenger
[...]
Installing RDoc documentation for passenger-2.2.4...
Take note of where the passenger gem installed the nginx module code that will be required further down:
$ gem contents passenger | egrep '/ext/nginx/' | head -n 1
/var/lib/gems/1.8/gems/passenger-2.2.4/ext/nginx/Configuration.c
In this case the install directory will be /var/lib/gems/1.8/gems/passenger-2.2.4/ext/nginx.
Compile nginx passenger moduleYou also need to compile the passenger nginx module if it was not already compiled:
$ cd /var/lib/gems/1.8/gems/passenger-2.2.4/ext/nginx
$ sudo rake nginx
(in /var/lib/gems/1.8/gems/passenger-2.2.4)
mkdir -p ext/nginx/libboost_oxt/boost
g++ -Iext -D_REENTRANT -I/usr/local/include -Wall -g -DPASSENGER_DEBUG -DBOOST_DISABLE_ASSERTS -o ext/nginx/libboost_oxt/boost/exceptions.o -c ext/boost/src/pthread/exceptions.cpp
[...]
g++ ext/nginx/HelperServer.cpp -o ext/nginx/HelperServer -Iext -Iext/common -D_REENTRANT -I/usr/local/include -Wall -g -DPASSENGER_DEBUG -DBOOST_DISABLE_ASSERTS ext/nginx/libpassenger_common.a ext/nginx/libboost_oxt.a -lpthread
Install build packages
$ sudo aptitude install fakeroot debhelper dpkg-dev autotools-dev libpcre3-dev libssl-dev
Modify APT sources.listOpen /etc/apt/sources.list and ensure you add deb-src lines for each of the universe repos. The easiest way to do this is to simply copy the universe repo lines that exist and change the starting deb to deb-src:
deb http://au.archive.ubuntu.com/ubuntu/ jaunty universe
deb-src http://au.archive.ubuntu.com/ubuntu/ jaunty universe
deb http://au.archive.ubuntu.com/ubuntu/ jaunty-updates universe
deb-src http://au.archive.ubuntu.com/ubuntu/ jaunty-updates universe
Replace 'au.archive.ubuntu.com' with the repo closest to you and also replace 'jaunty' with your distro. Ensure you do a 'sudo aptitude update' to load the latest package indexes.
Set up a packaging environment
$ mkdir -p /var/tmp/nginx-passenger && cd /var/tmp/nginx-passenger
$ apt-get source nginx

Package customizationsIn order to build our nginx-passenger custom package we need to modify the following packaging resources:
- control file
- changelog file
- rules file
- nginx.install file
- nginx.logrotate file
- passenger.conf file
- postinst file
Control file
$ cd nginx-passenger-0.6.35/debian
Edit the control file and change the Source, Maintainer, Uploaders, Package, Provides, Conflicts and Description fields:
Source: nginx-passenger
Maintainer: Charl Matthee
Uploaders: Charl Matthee
Package: nginx-passenger
Provides: httpd, nginx
Conflicts: nginx
Description: small, but very powerful and efficient web server
Nginx (engine x) is a web server created by Igor Sysoev and kindly provided
to the open-source community. This server can be used as standalone HTTP
server and as a reverse proxy server before some Apache or another big
server to reduce load to backend servers by many concurrent HTTP-sessions.
.
This is a custom nginx package that includes Phusion Passenger
support for nginx.
Note: spacing in the control file is significant.More information on the control file internals can be found
here.
ChangelogAdd a new changelog entry in the changelog file:
nginx-passenger (0.6.35-0custom1) jaunty; urgency=low
* New custom Passenger Phusion nginx module addition
-- Charl Matthee Mon, 29 Jun 2009 09:08:36 +0100
nginx (0.6.35-0ubuntu1) jaunty; urgency=low
* New upstream bugfix release
-- Daniel Hahler Fri, 20 Feb 2009 21:01:23 +0100
[...]
More information on the changelog file internals can be found
here.
RulesAdd the passenger module inclusion to the configure script options when nginx is built by modifying the './configure $(CONFIGURE_OPTS)' block in the rules file like this:
./configure $(CONFIGURE_OPTS) --conf-path=/etc/nginx/nginx.conf \
--error-log-path=/var/log/nginx/error.log --pid-path=/var/run/nginx.pid \
--lock-path=/var/lock/nginx.lock --http-log-path=/var/log/nginx/access.log \
--http-client-body-temp-path=/var/lib/nginx/body --http-proxy-temp-path=/var/lib/nginx/proxy \
--http-fastcgi-temp-path=/var/lib/nginx/fastcgi --with-http_stub_status_module \
--with-http_flv_module --with-http_ssl_module --with-http_dav_module \
--with-http_realip_module --add-module=PASSENGER_LIB_DIR
Where PASSENGER_LIB_DIR is the path you noted above when you installed the passenger gem. So, the updated block looks like this:
./configure $(CONFIGURE_OPTS) --conf-path=/etc/nginx/nginx.conf \
--error-log-path=/var/log/nginx/error.log --pid-path=/var/run/nginx.pid \
--lock-path=/var/lock/nginx.lock --http-log-path=/var/log/nginx/access.log \
--http-client-body-temp-path=/var/lib/nginx/body --http-proxy-temp-path=/var/lib/nginx/proxy \
--http-fastcgi-temp-path=/var/lib/nginx/fastcgi --with-http_stub_status_module \
--with-http_flv_module --with-http_ssl_module --with-http_dav_module \
--with-http_realip_module --add-module=/var/lib/gems/1.8/gems/passenger-2.2.4/ext/nginx/
More infomration on the changelog file internals can be found
here.
nginx.installMove this file to the correct name based on the package name and add the installation instructions for the default nginx configuration that is required to turn passenger support on:
$ mv nginx.install nginx-passenger.install
$ cat nginx-passenger.install
objs/nginx usr/sbin
html/* var/www/nginx-default
debian/conf/* etc/nginx
debian/passenger.conf etc/nginx/conf.d/
debian/NEWS.Debian usr/share/doc/nginx
nginx.logrotateMove this file to the correct name based on the package name:
$ mv nginx.logrotate nginx-passenger.logrotate
passenger.confCreate the following file in the debian directory:
passenger_root /var/lib/gems/1.8/gems/passenger-2.2.4;
passenger_ruby /usr/bin/ruby1.8;
Ensure those paths point to the correct passenger isntall and ruby directories.
postinstAdd the following steps to the postinst script after the '#DEBHELPER#' token:
# Phusion Passenger module settings for nginx
echo
echo "***********************************************************************"
echo "For each virtual host you want to add Phusion Passenger support for you"
echo "need to create a config like this in /etc/nginx/site-available:"
echo
echo " server {
listen 80;
server_name DOMAIN_NAME;
root /var/www/RAILS_PROJECT/public; #<--- be sure to point to 'public'!
passenger_enabled on;
}"
echo
echo "Don't forget to add a symlink from this file(s) to"
echo "/etc/nginx/site-enabled to enable the configuration in nginx."
echo "***********************************************************************"
echo
This will warn administrators that install this package that they still need to do some manual work to get a virtual host set up to take advantage of the passenger module.
Package rebuildThe package can then be rebuilt just like any other custom deb:
$ cd /var/tmp/nginx-passenger/nginx-passenger-0.6.35
$ dpkg-buildpackage -rfakeroot
dpkg-buildpackage: set CFLAGS to default value: -g -O2
[...]
dpkg-deb: building package `nginx-passenger' in `../nginx-passenger_0.6.35-0custom1_i386.deb'.
dpkg-deb: ignoring 1 warnings about the control file(s)
signfile nginx-passenger_0.6.35-0custom1.dsc
gpg: skipped "Charl Matthee ": secret key not available
gpg: [stdin]: clearsign failed: secret key not available
dpkg-genchanges >../nginx-passenger_0.6.35-0custom1_i386.changes

Those signing errors were triggered because I have did not have the required key infrastructure installed. They can be ignored for the moment.
Install the new package:
$ sudo dpkg -i ../nginx-passenger_0.6.35-0custom1_i386.deb
[...]
Setting up nginx-passenger (0.6.35-0custom1) ...
***********************************************************************
Create a config like this for each virtual host you want to add Phusion
Passenger support to. They should be created in
/etc/nginx/site-available:
server {
listen 80;
server_name DOMAIN_NAME;
root /var/www/RAILS/public; # <--- be sure to point to 'public'!
passenger_enabled on;
}
Don't forget to add a symlink from this file(s) to
/etc/nginx/site-enabled to enable the configuration in nginx.
***********************************************************************
[...]
Nginx passenger configurationTo enable and take advantage of the passenger nginx module you need to create a /etc/nginx/conf.d/passenger.conf config:
passenger_root /var/lib/gems/1.8/gems/passenger-2.2.4;
passenger_ruby /usr/bin/ruby1.8;
This will of course have been done when we installed our custom package.
Next, add a virtual host for each of the rails applications you want to support by dropping a file like 'foo' into /etc/nginx/sites-available/:
server {
listen 80;
server_name foo.example.com;
root /var/www/foo/public; # <--- be sure to point to 'public'!
passenger_enabled on;
}
Ensure that the port, server_name and root variables have valid values for your environment.
If you want to use a non-production rails environment you can add the following to the block after passenger_enabled:
rails_env development;
To enable the virtual host(s) you need to ensure that there's a symlink linking the virtual host in sites-available to sites-enabled:
$ sudo ln -s /etc/nginx/sites-available/foo /etc/nginx/sites-enabled/foo
$ ls -la /etc/nginx/sites-enabled
total 8
drwxr-xr-x 2 root root 4096 2009-06-29 12:33 .
drwxr-xr-x 5 root root 4096 2009-06-29 10:51 ..
lrwxrwxrwx 1 root root 34 2009-06-02 07:25 default -> /etc/nginx/sites-available/default
lrwxrwxrwx 1 root root 30 2009-06-29 12:33 foo -> /etc/nginx/sites-available/foo
Once done you can restart nginx and you should see the following processes that confirm things are running:
$ ps axf | egrep "nginx|passenger"
28608 pts/1 S+ 0:00 \_ egrep nginx|passenger
28560 pts/1 Sl 0:00 PassengerNginxHelperServer /var/lib/gems/1.8/gems/passenger-2.2.4 /usr/bin/ruby1.8 3 4 0 6 0 300 1 nobody 33 33 /tmp/passenger.28557
28580 ? Ss 0:00 nginx: master process /usr/sbin/nginx
28581 ? S 0:00 \_ nginx: worker process
The final test to see if everything is working is to open a browser and to browse to the server_name and port defined above. Errors will be reported in /var/log/nginx/error.log as well as the development/production logs of the rails project you're running.
