Simple (lazy) nginx-rtmp install script I use for setting up servers, it's obviously missing the configuration part

nginxrtmp_install.sh

#!/bin/bash

set -e
apt-get update
apt-get -y upgrade
apt-get remove -y nginx-common nginx-full
rm -rf /usr/src/nginx* /usr/src/headers-more-nginx-module
# build dependencies
apt-get -y install dpkg-dev git autotools-dev debhelper po-debconf dh-systemd  libexpat-dev libgd2-dev libgeoip-dev libluajit-5.1-dev libmhash-dev libpam0g-dev libpcre3-dev libperl-dev libssl-dev libxslt1-dev zlib1g-dev autotools-dev de$
cd /usr/src
apt-get -y source nginx
git clone https://github.com/arut/nginx-rtmp-module.git
cd /usr/src/nginx-1*/
awk '/common_configure_flags := \\/{print;print "     --add-module=/usr/src/nginx-rtmp-module\\";next}1' debian/rules > debian/rules.tmp
rm debian/rules
mv debian/rules.tmp debian/rules
dpkg-buildpackage -b
cd ..
dpkg --install nginx-common_*.deb
dpkg --install nginx-full_*.deb
