Normally in Ubuntu we might add the Nginx repository and install Nginx like so:

sudo add-apt-repository -y ppa:nginx/stable sudo apt-get update sudo apt-get install -y nginx

But if we want some extra modules, such as Google's Pagespeed or perhaps the HTTP upload module, we actually need to recompile Nginx with those modules.

Compiling Nginx from source isn't actually too hard, BUT we lose out on important additions the Debian package provides.

The Debian package provided by ppa:nginx/stable sets up configuration to monitor and start Nginx on system boot (Upstart/SysInit), logrotate and other system needs. These are things we would otherwise need to setup manually. We don't want to skip these by installing from source!

However, there's a way to have our cake and eat it to. We can use the repository's package to:

1. Get the sources/dependencies used to
2. Add our modules to the ppa:nginx/stable package
3. Rebuild the packages
4. Re-install Nginx

If you already have Nginx installed, you can still proceed with the following. I would backup any sites-available or customer configuration first. You can remove Nginx first if you run into issues: sudo apt-get remove nginx.

Get Extra Modules

Before we start to get the Nginx dependencies, we'll first download the module files.

Let's get the Pagespeed module files (latest version 1.9.32.2) as per their docs, with a little adding of "sudo" in my case:

sudo mkdir /opt/pagespeed cd /opt/pagespeed NPS_VERSION=1.9.32.2 sudo wget https://github.com/pagespeed/ngx_pagespeed/archive/release-${NPS_VERSION}-beta.zip sudo unzip release-${NPS_VERSION}-beta.zip cd ngx_pagespeed-release-${NPS_VERSION}-beta/ sudo wget https://dl.google.com/dl/page-speed/psol/${NPS_VERSION}.tar.gz sudo tar -xzvf ${NPS_VERSION}.tar.gz # extracts to psol/ # Gives us directory /opt/pagespeed/ngx_pagespeed-release-1.9.32.2-beta

Then we can get the HTTP Upload Module (latest version 2.2) as per the docs:

sudo mkdir /opt/httpupload cd /opt/httpupload sudo wget https://github.com/vkholodkov/nginx-upload-module/archive/2.2.zip sudo unzip 2.2.zip # Gives us directory: /opt/httpupload/nginx-upload-module-2.2

Get Nginx Sources & Dependencies

Alright, now the parts that might be more unfamiliar to you. We're going to get the Nginx packages from ppa:nginx/stable, adjust them, rebuild them, and then reinstall Nginx.

This assumes you've added the ppa:nginx/stable repository already. Ensure that the file /etc/apt/sources.list.d/nginx-stable-trusty.list exists. Not that mine says "trusty" because I'm using Ubuntu Trusty (14.04).

First, edit the PPA's sources file and ensure the deb-src directive is not commented out. This will let us get the sources files:

$ cat /etc/apt/sources.list.d/nginx-stable-trusty.list deb http://ppa.launchpad.net/nginx/stable/ubuntu trusty main # deb-src http://ppa.launchpad.net/nginx/stable/ubuntu trusty main

If, like mine, your deb-src line is commented out, edit that file and remove the #:

$ cat /etc/apt/sources.list.d/nginx-stable-trusty.list deb http://ppa.launchpad.net/nginx/stable/ubuntu trusty main deb-src http://ppa.launchpad.net/nginx/stable/ubuntu trusty main

Then update:

sudo apt-get update

Now we can continue to get the source packages of Nginx, adjust it, build it and install it!

First we'll get the source package and any needed system dependencies:

# Install package creation tools sudo apt-get install -y dpkg-dev sudo mkdir /opt/rebuildnginx cd /opt/rebuildnginx # Get Nginx (ppa:nginx/stable) source files sudo apt-get source nginx # Install the build dependencies sudo apt-get build-dep nginx

Then we will adjust the build files to add the extra modules. As of the time of this writing, the latest stable Nginx installed on Ubuntu Trusty is 1.6.2.

$ ls -lah /opt/rebuildnginx drwxr-xr-x 10 root root 4096 Dec 14 16:37 nginx-1.6.2/ -rw-r--r-- 1 root root 934244 Dec 14 02:10 nginx_1.6.2-5+trusty0.debian.tar.gz -rw-r--r-- 1 root root 2798 Dec 14 02:10 nginx_1.6.2-5+trusty0.dsc -rw-r--r-- 1 root root 804164 Sep 18 21:31 nginx_1.6.2.orig.tar.gz

To adjust add the modules into the build, edit the /opt/rebuildnginx/nginx-1.6.2/debian/rules file.

The ppa:nginx/stable has multiple Nginx packages available: common, light, full and extras. When you run apt-get install -y nginx, you're installing the "full" version.

The "common" package is the base install upon which the others are built. The "lighter" package, however is in fact lighter than the "common" package due to the use of the --without-* flags.

For this example, we'll simply edit the "full" version to add our modules. This assumes we'll keep using the "full" package as normal when installing Nginx.

From the rules file, here's the "full" version configuration with our 2 new modules added at the end:

full_configure_flags := \ $(common_configure_flags) \ --with-http_addition_module \ --with-http_dav_module \ --with-http_geoip_module \ --with-http_gzip_static_module \ --with-http_image_filter_module \ --with-http_spdy_module \ --with-http_sub_module \ --with-http_xslt_module \ --with-mail \ --with-mail_ssl_module \ --add-module=$(MODULESDIR)/nginx-auth-pam \ --add-module=$(MODULESDIR)/nginx-dav-ext-module \ --add-module=$(MODULESDIR)/nginx-echo \ --add-module=$(MODULESDIR)/nginx-upstream-fair \ --add-module=$(MODULESDIR)/ngx_http_substitutions_filter_module \ --add-module=/opt/httpupload/nginx-upload-module-2.2 \ --add-module=/opt/pagespeed/ngx_pagespeed-release-1.9.32.2-beta

Once that's edited and saved, we can build Nginx!

cd /opt/rebuildnginx/nginx-1.6.2 sudo dpkg-buildpackage -b

This will take a few minutes.

Install Nginx

Once the build is complete, we'll find a bunch of .deb files added in /opt/rebuildnginx. We can use these to install Nginx.

We adjusted the "full" package, and so we'll want to use that build to install Nginx. Looking at the deb files, we'll see two "full" packages:

nginx-full-dbg_1.6.2-5+trusty0_amd64.deb nginx-full_1.6.2-5+trusty0_amd64.deb

I'm on a 64bit version of Ubuntu, so I'm using the amd64 version. The dbg version is a debug version, so we'll use the other package to install Nginx:

# .deb files appear one level above the `nginx-1.6.2` directory cd /opt/rebuildnginx sudo dpkg --install nginx-full_1.6.2-5+trusty0_amd64.deb

That step should be done quickly.

Our recompiled Nginx is installed! We can use nginx -V (capital "V") to see which flags were used during compilation, letting us know which modules are installed:

$ nginx -V nginx version: nginx/1.6.2 TLS SNI support enabled configure arguments: --with-cc-opt='-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2' # A bunch of these removed for brevity --add-module=/opt/httpupload/nginx-upload-module-2.2 # yay! --add-module=/opt/pagespeed/ngx_pagespeed-release-1.9.32.2-beta # yay!

The last two are our new modules!

Test Pagespeed

Create a cache directory for Pagespeed items:

sudo mkdir -p /var/cache/ngx_pagespeed/

Edit the /etc/nginx/nginx.conf file to enable Pagespeed.

# Stuff up here omitted server { pagespeed On; pagespeed FileCachePath "/var/cache/ngx_pagespeed/"; pagespeed EnableFilters combine_css,combine_javascript; # Stuff down here omitted }

Save that, then test the configuration:

$ sudo service nginx configtest * Testing nginx configuration [ OK ] # Restart, assuming it's OK $ sudo service nginx restart

I haven't gone into the details of configuring Pagespeed for your server, but there's lots of good information on configuring Mod Pagespeed here.

For the HTTP Upload module, I haven't included the HTTP Upload Progress module. You can add that into "full" manually, or add the Upload and Pagespeed modules into the "extras" package and install it.
