I am trying to dynamically load a third party module to nginx.
https://github.com/stnoonan/spnego-http-auth-nginx-module
Nginx is installed via package installation using chef recipe.
I have tried compiling the module to module binary .so file and copied it to /etc/nginx/modules directory and added the following line into nginx.conf, but it showed error "unknown directive load_module".
nginx.conf
load_module modules/ngx_http_auth_spnego_module.so ;
Chef recipe
bash 'create_spnego_module' do
code <<-EOH
mkdir -p #{node['nginx']['dir']}/modules
EOH
end
cookbook_file "#{node['nginx']['dir']}/modules/ngx_http_auth_spnego_module.so" do
source 'ngx_http_auth_spnego_module.so'
owner 'root'
group node['root_group']
mode '0644'
notifies :reload, 'service[nginx]', :delayed
end
Is there any other way I can load this module via chef without recompiling nginx source?
As mentioned in comments, your version of Nginx is too old for dynamic module loading. You'll either need to recompile it with the new module or install a new version.
During compilation of module binary , the configuration arguments for compiling modules should be the same as that of the installed nginx.
Using command line argument 'nginx -V' , check the configuration arguments during nginx installation. Use the same arguments during module compilation.

When running nginx -t I get this error:
nginx: [emerg] unknown directive "subs_filter_types" in /etc/nginx/sites-enabled/my.site.com.conf:285
nginx: configuration file /etc/nginx/nginx.conf test failed
So I need to install the substitution filter module and in the nginx documentation https://www.nginx.com/resources/wiki/modules/substitutions/#subs-filter-types
Which says to run these commands:
git clone git://github.com/yaoweibin/ngx_http_substitutions_filter_module.git
./configure --add-module=/path/to/module
The problem is I don't have the configure script anywhere in my nginx installation nor in the
git repository. I really don't understand.
At the very least I want to know the content of that nginx configure script.
The instructions you are referring to are for compiled installation.
Assuming you want to add the module to your existing NGINX install, below are the generic steps that will get things running.
Fetch exactly matching version of NGINX as the one you have installed, from nginx.org onto your system and extract it to, say, /usr/local/src/nginx
git clone NGINX module's source code onto your system, to e.g. /usr/local/src/nginx-module-foo
cd /usr/local/src/nginx. This is where you will find the configure script. You will basically configure NGINX with the location of the config of specific module in question, thus next step:
./configure --add-dynamic-module=../nginx-module-foo --with-compat
make
As a resulf of the compilation you will have module's .so file somewhere in objs directory of your NGINX sources. You will then copy it over to e.g. /usr/lib64/nginx/modules/ directory.
To make your existing NGINX load the module, add load_module modules/foo.so; at the very top of /etc/nginx/nginx.conf.
You can decipher the many downsides to the whole compiled approach: one is having compilation software (gcc) on a production system, other is having to re-do all those steps any time you upgrade NGINX or the module.
For the reasons mentioned, you might want to search for a packaged install of third-party modules.
For CentOS/RHEL systems, you might want to look at GetPageSpeed repos (subscription-ware, and I'm biased to mention it, because I'm the maintainer. But this is free for CentOS/RHEL 8 at the time of this writing. Installing the module you want, goes down to a couple of commands:
yum -y install https://extras.getpagespeed.com/release-latest.rpm
yum -y install nginx-module-substitutions
For Debian-based systems, probably there are alternative PPAs existing for the same.
Just replace prefix subs with sub.
For default nginx 1.10.3 installation (Ubuntu 16.04.5 LTS)
nginx -V should have flag --with-http_sub_module to use sub_* directives.
Usage example:
sub_filter_types text/html text/css text/xml;
sub_filter 'needle' 'replacement';
sub_filter_once off;

I have just started to experiment with Zephir over the weekend, and had managed to compile and run a hello world extension on the mac terminal. I have AMPPS installed, and am trying to install this extension on AMPPS. Not sure if my steps are correct, but if I copied the .so file over, I get this error from AMPPS:
Warning: PHP Startup: Unable to load dynamic library '/Applications/AMPPS/php-7.1/lib/extensions/ext/utils.so' - dlopen(/Applications/AMPPS/php-7.1/lib/extensions/ext/utils.so, 9): no suitable image found. Did find: /Applications/AMPPS/php-7.1/lib/extensions/ext/utils.so: mach-o, but wrong architecture /Applications/AMPPS/php-7.1/lib/extensions/ext/utils.so: stat() failed with errno=3 in Unknown on line 07.1.2
What is the correct way to install the compiled extensions on hosted servers in future?
The ERROR was obvious ： Unable to load dynamic library '/Applications/AMPPS/php-7.1/lib/extensions/ext/utils.so' . That may mean your .so lib was not found. Maybe you past your extension lib file into an incorrect path.
So you can try to type php -i | grep extension in your terminal.
And it will output your extension path like extension_dir => /usr/local/lib/php/extensions/no-debug-non-zts-20151012 => /usr/local/lib/php/extensions/no-debug-non-zts-20151012.
Check your extension exist or not in this direction.
BTW you can using command php -m to check how many extensions you have installed .
I have installed nginx/1.12.1 and Phusion Passenger by APT from https://oss-binaries.phusionpassenger.com repository. It's configured correctly within my Rails apps.
Thereafter, I want to improve nginx by adding nginx pagespeed module dynamically following this https://www.modpagespeed.com/doc/build_ngx_pagespeed_from_source to build ngx_pagespeed module and following this https://www.nginx.com/blog/compiling-dynamic-modules-nginx-plus/ to compile dynamic module, by running :
$ ./configure --with-compat --add-dynamic-module=$HOME/ngx_pagespeed-${NPS_VERSION} ${PS_NGX_EXTRA_FLAGS}
$ make modules
After that, I copied ngx_pagespeed.so from objs/ folder into /etc/nginx/modules and of course loading the module into nginx.conf by adding load_module modules/ngx_pagespeed.so; on it. But when I reload nginx it's reproduced following error:
nginx: [emerg] module "/usr/share/nginx/modules/ngx_pagespeed.so" is not binary compatible in /etc/nginx/nginx.conf:5
My question is:
How do I add ngx_pagespeed module on nginx from PhusionPassenger APT?
What is the right ./configure flags for compiling additional module without forgetting previous installed nginx (from PhusionPassenger APT) modules?
Thank you
On ubuntu xenial, you'll have an easier time adding your configure flags to the passenger-install-nginx-module script like so: passenger-install-nginx-module --extra-configure-flags="--with-compat --add-dynamic-module=$HOME/ngx_pagespeed-${NPS_VERSION} ${PS_NGX_EXTRA_FLAGS}" instead of using the nginx-extras package, as matching the flags from the packaging process at phusion is a pain. You can read more about it here: https://www.phusionpassenger.com/library/install/nginx/customizing_compilation_process.html
I have installed Nginx in our redhat machine using rpm. Now we want to add nginx-rtmp module, but inorder to add new module as per the document i need to build it by downloading the tar ball. Does it mean that i have to remove the rpm and install it as per the document.
Ref: https://github.com/arut/nginx-rtmp-module/wiki/Getting-started-with-nginx-rtmp
./configure --add-module=/usr/build/nginx-rtmp-module
make
make install
With nginx 1.9.11, it's not necessary to recompile the server, as they added support for dynamic modules. Take a look here:
https://www.nginx.com/blog/dynamic-modules-nginx-1-9-11/
Unlike Apache, all modules, including the 3rd party modules, are going to be compiled into nginx. So every time you want to add a new module, you have to recompile nginx.
So yes, you have to install it as per the document. There is no much value of keeping 2 nginx runtimes on the same server any way. So you may also want to remove the previous nginx.
I had a similar problem where the auth-pam module broke after an upgrade. Here's what fixed it for me (debian stretch/sid, nginx 1.10.2):
apt install libnginx-mod-http-auth-pam
ln -s /usr/share/nginx/modules-available/mod-http-auth-pam.conf /etc/nginx/modules-enabled/50-mod-http-auth-pam.conf
The config file contains a single “load_module” directive which tells nginx to dynamically load the module on startup. As jekennedy mentioned, this would only apply to newer versions of nginx that support dynamic module loading.
Yes, you have to uninstall nginx (installed via rpm) and re-install it according to the mentioned document that is from source file. There are some disadvantages of installing nginx using source, like you cannot use nginx as a service. Here, you can find instructions to do same thing with all the functionalities you get while installing nginx using OS-respective packages.
Following the steps in this post from the nginx blog page called "Compilation of Dynamic Modules for NGINX Plus", i could compiled the RTMP módule, downloading the nginx-rtmp-module from Github and import it on my webserver.

I'm trying to move from Apache + Passenger to Nginx + passenger on my Ubuntu Lucid Lynx box.
When I install passenger:
sudo gem install passenger
and
cd /var/lib/gems/1.9.1/gems/passenger-2.2.14/bin
sudo ./passenger-install-nginx-module
everything is fine (no error). Nginx is downloaded and compiled and installed at the same time (when selecting the first option during passenger installation). By default it is installed in /opt/nginx.
I end up with the configuration file /opt/nginx/conf/nginx.conf; This conf file was automatically updated with passenger config). The thing I do not understand is that I also have the configuration file /etc/nginx/nginx.conf. What is the purpose of this one when it seems that the conf file in /opt/... is the main one?
When I run /etc/init.d/nginx start, it starts correclty saying that /etc/nginx/nginx.conf is ok. Does it mean that it does not check the other conf file?
I updated /etc/init.d/nginx script and added /opt/nginx/sbin at the beginning of the PATH and it seems the correct conf file is taken into account. It seems like I have two nginx installations where I only relied on passenger to install it.
You did end up with 2 Nginx installations:
The one installed globally by your OS's package manager (/usr/sbin/nginx). This uses /etc/nginx/nginx.conf as configuration file by default.
The one installed by Phusion Passenger (/opt/nginx/sbin/nginx). This uses /opt/nginx/conf/nginx.conf as configuration file by default.
Only (2) has Phusion Passenger support. Ignore (1) and do not use it.
I don't think that this is a programming related question, but anyway...
It seems like passenger installation have configured nginx to look for config file in /etc/nginx. Post your nginx configure flags and check if /etc/init.d/nginx overrides config file path.
