How to compile the ngx_pagespeed (Nginx Pagespeed) module for ARM architecture on the Raspberry Pi 4, or any other aarch64 devices, running Ubuntu Server 20.04

Before you read:

To skip this tutorial and download a precompiled version of Pagespeed for Nginx-1.21.6 Mainline, you can check out the nerd-tech github link here: For this module to be compatible, you must be running Nginx Mainline v1.21.6 on Ubuntu Server 20.04 for the Raspberry Pi 3 or Raspberry Pi 4. Check the github page for more compatibility info on this precompiled Pagespeed module for the Raspberry Pi.


If you are using a Raspberry Pi as a LEMP (Linux, Nginx, MariaDB, PHP) server to host your website, you may want to consider speeding up your site on the server level by using the pagespeed module for Nginx. In this tutorial, we are going to learn how to compile (build) and install google’s ngx_pagespeed module for the Nginx Mainline Version 1.21.6, on a Raspberry Pi 3, Raspberry Pi 4, or any 64 bit ARM (aarch64) Device.

Natively, the ngx_pagespeed module does not support ARM device, nor do they have ARM support in their development roadmap. This poses a problem for users running a web server on aarch64 devices such as the Raspberry Pi 3 and above. This is mostly due to the fact that the PSOL binaries required to compile the pagespeed module are not 64-bit ARM or armv7l compatable. Fortunately, a developer by the name of Mogwai (@gusco) on gitlab, has solved this issue by patching the PSOL Binaries to make them compatible with aarch64/armv7l operating systems and their respective devices. This in turn, makes compiling the Nginx pagespeed module now possible for ARM devices.

As a reference note, This tutorial was created by merging/modifying three different tutorials and sets of instructions into one clean ARM versioned tutorial. You can find the original sources/tutorials/content on Linuxbabe’s page, on the Mogwai Gitlab page and on the official google pagespeed documentation page. Keep in mind, this has only been tested by me on Ubuntu Server (64-bit) 20.04 for the Raspberry Pi 4. However, it should also work on any 64 bit ARM device running Ubuntu 20.04, or any 64-bit version of Rasperry Pi OS. So, without further ado, lets begin:

Before you begin: You should do this on a machine (or seperate SD card) that IS NOT your real production web server or LEMP server! This will prevent code litter scattered throughout your server. Just be sure to use the same OS, Same Architecture, and Same Nginx version.

Step 1) Install the Nginx Mainline repository and corresponding signing keys

sudo nano /etc/apt/apt/sources.list.d/Nginx.list

Then copy and paste the following text into the file.

# Nginx Official Repositories for Ubuntu 20.04 Focal

# Official Nginx Stable Repository for Ubuntu 20.04 Raspi
# Stable Nginx and Nginx source repositories
#deb [arch=arm64] focal nginx
#deb-src [arch=arm64] focal nginx

# Official Nginx Mainline Repository for Ubuntu 20.04 Raspi
deb [arch=arm64] focal nginx
deb-src [arch=arm64] focal nginx

Then update or add the Official Nginx Signing Key to your GPG Keyring.

cd ~/ && curl -O && sudo apt-key add ./nginx_signing.key

Then type:

apt-key list

and you should see the following text appear.

pub   rsa2048 2011-08-19 [SC] [expires: 2024-06-14]
      573B FD6B 3D8F BC64 1079  A6AB ABF5 BD82 7BD9 BF62
uid           [ unknown] nginx signing key <>


Be sure the fingerprints (573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62) match. Then proceed to update, upgrade, and finally install nginx.

sudo apt update && sudo apt upgrade && sudo apt install nginx

Once installed you can check and be sure your version of nginx is 1.21.6 with nginx -v. Then proceed to the next step, which is taken almost directly from

STEP 2) Download nginx source package

Modify this line by changing “yourusername” to your real Ubuntu login user name. Then copy the rest of the line and paste it in your linux terminal.

sudo chown yourusername:yourusername -R /usr/local/src/ && sudod mkdir -p /usr/local/src/nginx && cd /usr/local/src/nginx/ && sudo apt install dpkg-dev && sudo apt source nginx && ls

The final “ls” command should show the following output:


STEP 3) Download the Pagespeed source package

Here is where we do something different for ARM devices. The PSOL (pagespeed optimization Libraries) provided by google are not compatable with ARM devices. Therefore, we are going to use a patched version of the PSOL. Paste this entire one liner to clone the pagespeed module from github, convert it to the stable branch, and then download and extract the aarch64 patched version of the PSOL into the proper directory.

cd /usr/local/src && git clone && cd incubator-pagespeed-ngx/ && git checkout latest-stable && wget && tar xvf psol- && sed -i 's/x86_64/aarch64/' config && sed -i 's/x64/aarch64/' config && sed -i 's/-luuid/' config

STEP 4) Configure the Pagespeed module.

CD into the Nginx directory and install the build dependancies.

cd /usr/local/src/nginx/nginx-1.21.6 && sudo apt build-dep nginx && sudo apt install uuid-dev

Finally, we need to configure the environment with the exact same arguments that are already in your currently installed Nginx. To do that, you have to first check your nginx arguments with the following command:

nginx -V

Should return:

configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/ --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-g -O2 -fdebug-prefix-map=/data/builder/debuild/nginx-1.21.6/debian/debuild-base/nginx-1.21.6=. -fstack-protector-strong -Wformat -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fPIC' --with-ld-opt='-Wl,-Bsymbolic-functions -Wl,-z,relro -Wl,-z,now -Wl,--as-needed -pie'

If the “--with-compat” and “--with-cc-opt='-DNGX_HTTP_HEADERS'” arguments are not in there, then you must be sure to them to the next command or your module won’t be compatable with your Nginx. If “--with-compat” is in the above set of arguments, then just continue to copy and paste the above arguments in the next command along with “--with-cc-opt='-DNGX_HTTP_HEADERS'“. Either way, the arguments”--with-compat” and “--with-cc-opt='-DNGX_HTTP_HEADERS'” MUST be in the next command. Lastly, since we are compiling pagespeed as a dynamic argument, we must also include “--add-dynamic-module=/usr/local/src/incubator-pagespeed-ngx” argument. To summarize, the new arguments look like this:

--add-dynamic-module=/usr/local/src/incubator-pagespeed-ngx --with-compat --with-cc-opt='-DNGX_HTTP_HEADERS'

RUNNING MY FINAL ./CONFIGURE COMMAND LOOKS LIKE THIS (adjust according your output of the nginx -V command):

./configure --add-dynamic-module=/usr/local/src/incubator-pagespeed-ngx --with-compat --with-cc-opt='-DNGX_HTTP_HEADERS'

So in my case, since I am compiling for the latest Mainline version of Nginx v1.21.6, my entire configure command, including arguments (with the NEW Additional Arguments first) would be as follows:

./configure --add-dynamic-module=/usr/local/src/incubator-pagespeed-ngx --with-cc-opt='-DNGX_HTTP_HEADERS' --with-compat --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/ --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-g -O2 -fdebug-prefix-map=/data/builder/debuild/nginx-1.21.6/debian/debuild-base/nginx-1.21.6=. -fstack-protector-strong -Wformat -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fPIC' --with-ld-opt='-Wl,-Bsymbolic-functions -Wl,-z,relro -Wl,-z,now -Wl,--as-needed -pie'

So to complete this step, just copy and paste:

./configure --add-dynamic-module=/usr/local/src/incubator-pagespeed-ngx --with-cc-opt='-DNGX_HTTP_HEADERS' --with-compat

before the rest of the output of nginx -V and then hit enter to start configuring! Don’t forget to check for an already existing --with-compat argument before you paste the above line.

STEP 5) Make the Pagecache module!

cd /usr/local/src/nginx/nginx-1.21.6/ && make modules

Then copy your newly created module to the Nginx modules directory.

cd objs && sudo cp /etc/nginx/modules/

Step 5b) – (Recommended) – Copy the pagespeed module to your production server

If you built this module on an alternate copy of ubuntu rather than your main production server (which you should have), then you should copy your newly created module to a usb stick from your development server, and then from your usb stick to your production server.

First insert your ext4 or dos formatted usb stick into your development server. Then make a mount directory for it.

sudo mkdir /mnt/usb1

Next, Check your device name for your usb stick


It should show up as /dev/sda or /dev/sdb. Mount it (depending on what is shows up as in lsblk):

sudo mount /dev/sda /mnt/usb1

then copy your module to your mounted usb stick:

sudo cp /usr/local/src/nginx/nginx-1.21.6/objs/ /mnt/usb1/

Unmount your usb with sudo umount /dev/sda then insert your usb into your production server, mount it, and copy the module to your modules folder in /etc/nginx/modules/.

STEP 6) Load the module

sudo nano /etc/nginx/nginx.conf

Then add the following line to the beginning of the file:

load_module modules/;

Underneath the lines…

user www-data;
worker_processes auto;
pid /run/;
load_module modules/;

Now it’s your job to set up and configure the Nginx Filter settings. You can find the list of filters here.

Congrats, you can STOP because you are all done! Now you have a working pagespeed module for your 64 bit ARM Raspberry Pi 4!
