Compile dynamic nginx modules

My notes for compiling modules in nginx.  As of nginx 1.9.11, you can dynamically load modules using load_module in nginx.conf.  To compile the module, if not available in your repo or you’re running latest version of nginx and not available in your repo, use -add-dynamic-module=path.

Install pre-requisite libraries for compile of nginx

apt-get install libpcre3-dev zlib1g-dev libssl-dev

Get echo-nginx-module

git clone https://github.com/openresty/echo-nginx-module

Get nginx build that matches my version

https://nginx.org/download/nginx-1.12.0.tar.gz
tar zxvf nginx-1.12.0.tar.gz
cd nginx-1.12.0.tar.gz

Configure make

./configure --add-dynamic-module=../echo-nginx-module --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/nginx.pid -- 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 -fstack-protector-strong -Wformat -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -Wl,--as-needed -pie'

Make (but not install)

make -j2

Copy modules to /etc/nginx/modules/

cp objs/ngx_http_echo_module.so /etc/nginx/modules/ngx_http_echo_module.so

Modify nginx configuration to load module

Edit /etc/nginx/nginx.conf and add line:

load_module modules/ngx_http_echo_module.so;

Create a test in site configuration

Edit /etc/nginx/conf.d/default.conf (Your site configuration file may differ…)
Add the following:

location /echo {
    echo "Hello, world!";
}

Restart nginx and test

/etc/init.d/nginx restart

Test!

root@debian:~# curl https://techish.net/echo
Hello, world!
